11. A REVISION OF THE POWDER-POST BEETLES OF THE FAMILY
'LYCTIDAE OF THE UNITED STATES AND EUROPE.

By E. 1. KRAUS,
Expert Prepara tor, Forest Insect In vest igatIions.
INTRODUCTORY NOTE.
[By A. D. HOPKiNs.]
This contribution by Mr. Kraus is based on a study (1) of the material in the forest insect collection and general collections of the Butreaui of Entomo logy and of the United States National Museum and (2) of the types of species described by Doctor Le Conte and Colonel Casey, and of specimens of Europea~n species submitted by Mr. Edmund Reitter, of Austria. The family Lyctidve is represented in North America by certain species which are of special economic importance as causing the injury to seasoned wood products known as "powder post." These species have been the subject of extended investigation by the writer and his associates to determine their habits, seasonal history, and practical methods, of control. There has, therefore, been special need of a revision of the group to bring the knowledge of systematic facts up to date and to furnish a reliable basis for working uip the biological data.
INTRODUCTION.

Much has been written regarding the mfemb}ers of the f amily Lyctidee, especially with respect to their economic importance. There has, however, been considerable doubt as to the correct idlentity of some of the species, perhaps more especially on account of their enormous variability. In this paper the author has attempted to point out the more prominent specific characters and, give something of the range of variation within the species as he has recognized them. For the determination of some of the species he has had occasion to examine a series of several hundred specimens. .Through the courtesy of Col. T. L. Casey, the author has been permitted to examine the types of his species. Mr. Samuel Henshaw, of the Museum of Comparative Zoology at Cambridge, Mass., has kindly permitted, him to make a personal examination of the Le Conte types; Dr. Henry Skinner, of the Academy of Natural Sciences, Philadel-

HISTORY.
Tfe genius L!/ctus an(I allied genera constitute a group which has al way b eeni a source of p~erplexi ty to systema tists, a(id the 'opinions as to their relationship have been almost as many and varied as the number of writers who have ventured them, as may in a general way be gained from the following summary:
T11. first reference to anl insect belonging to the present family Lyctidaw was made by (Jeoiii'oy (1762), whose description reads thus:
Derauwstes ob/ontu tisci.Cs, elviris stiaiis. Le (lernieste levrier sties.
The ne(xt reference, is by (ioeze (1777), who described the same insect as Dermcstcs itfl(Ufl8. Ini 1783 Hlerbst agai described andl fig tired ti e spec ies as Xhrni ( 8toid(s wiU ipwln eta tus. Oilivier, first in 1 790, and again inl19,(ecie a Ip ol -, adgvs a vei'y goo(l

of families, followed the BostricijidtV ~PwIii t he Lyctidaw, of whihl hie gives the following synopsis:

lie dividledl the family into two tribes, Dinodleriiia and Lyetina, the latter of which lie dliagnosedl thus: Antennie 11 -articulatwa, clava biarticulata. Labrurn transversurn, apice emarginato, libero. ()oxae anteriores rotun~lw parurn, })ostica', lat ius dislantes. Tibiwe externe haud dent iculatoe. Acetabula antica occl usa.
Pascoe (1863) described the genus inhthea andI remarked that in Erichison's arrangement this genus, owing to the position of the coxx andl the large basal abdominal- segment, would be placed with Bothrideres and Sosyl'us in the ColydIlidue. Redtenbacher (1874) placed Lyctus in the Cryptophagides. In 1877 Kiesenwetter, in his revision of the Anobiadve, divides the family into the Bostrichini, Anobiini, and Ptinini, and again divides the Bostrichini into five groups, Psoini, Sphindini, Lyctini, Bostrichini yeni, and Hendecatomini. Lyctus, in which lie included Xylotrogus Stephens, was the only representative of the Lyctini. lie further remarked that while this group is related to the Bostrichini it might well be considered as a connection between the Anobiadve and the Colydii, but that it was widely separated from C~is by its mouthparts and the antenfhal and tarsal structure, and that eventually a separate family might well be erected for it. He probably had not seen Thomson's work. The following year (1878) Reitter published an article, "Beitrag zur Kenntniss der Lyctidve." He assigned no characters to the family, but referred to it Lyctus Fabricius, Trogoxylon Le Conte, Lyctoxylon Reitter, new genus, and Lyctopholis iReitter, new genus (Jfinthea Pascoe), and described several new species. Le- Conte and Horn (1883) divided the Ptinidoe into four subfamilies, Ptininve, Anobiinaw, Bostrichinve, and Lyctinoe. To the Lyctinve are assigned Lyctus Fabricius and Trogoxylon Le Conte. In 1885 Reitter again gave a synopsis of the European species of L'yctus and Trogoxylon and assigns them as before to the family Lyctidoe. Casey (1890) diescribed several new species of Lyctus under the Ptinidue, but in the appendix of the same paper referred the genus to his more broadly conceived Cucujidoe, and gave a discussion on its apparent relationship to other families and genera. Lesne (1896-1898), in his revision of the Bostrichidee, (divided that family into four tribes-

Psoine, Polycaonine, Dinoderinm, and Bostrychine, but made no mention of Lyctus. Kolbe (1901) has retained the Lyctide as a family and placed it in his IHeterorrhabden under the suborder Heterophaga; and Ganglbauer (1903) placed the family between the Anobiide and Sphindide in his Diversicornia under the suborder Polyphaga. Reitter, in 1906, has the family between the Bostrychide and the Anobiidoe.
Without doubt the family Lyctide is a valid one, its members possessing characters which will not readily admit of their being placed in any other family. The family Ptinide of Le Conte and Horn is a composite one, and the subfamilies Ptinine, Anobiine, Bostrichinaw, and Lyetine are deserving of family rank and in fact have already been so treated by European coleopterists. While it is not intended to treat extensively on the exact position of the Lyctide, it may be said that the family is apparently most closely allied to the Bostrychide, especially by the pentamerous tarsi with the first segment very short, the method and point of insertion of the antennT, and the only too well-known destructive habits of the larve, which bore into the solid wood. The larva possesses three pairs of well-developed prothoracic legs, and in form and structure is scarcely to be distinguished from the bostrychid larva, but is totally different from any scolytid larva to which it has been likened, the resemblance being scarcely even superficial. The mouthparts of the adult Lyctus are very similar to those of Dinoderus, especially in the structure of the labium, maxills, and the broad mentum. The family has very little in common with the Cucujide. As pointed out above, the larva is of a wholly different character in form and habits, and the adults, while agreeing in one character or another with those found in certain other genera included by Colonel Casey in his broadly conceived Cucujide, have probably derived those characters in(lependlently of any real connection with them. The family seems best placed as in the latest (1906) edition of the Catalogus Coleopterorum Europa,, i. e., immediately after the Bostrychide and preceding the Ptinida.

Legs not contractile, slender; tibim slender; tarsi five-segmented, the first segment very short.

SYNOPSIS OF GENERA.

At present but three distinct genera belonging to this family are recognized. They may be separated as follows: Antennal club with both segments subequal, neither decidedly elongated; pronotum varying in shape from subquadrate with all angles acute to cordate with the angles rounded; elytra punctate, the punctures confused or distinctly seriate; pubescence confused or seriate; anterior tibiae slender, acutely produced externally; tarsi slender..................................................Lyctus Fabricius.
Antennal club with both segments very strongly elongated, the segments much longer than broad, the terminal one very much narrower than the preceding; sides of head with three hooklike teeth; the prothorax as in Lyctus (Trogoxylon), the margins, however, clothed with bristles; elytra punctured in not very regular rows, the pubescence, however, scarcely in rows; anterior tibia on either side strongly widened into a tooth externally, with a large tooth, straight at the base and hooklike at the apex; tarsi rather slender; claw-segment simple......Lyctoxylon Reitter. Antennal club with terminal segment elongate, sides of head with three weak teeth at either side; margins of pronotum denticulated and, like the margins of the body, with bristles; elytra striately punctured, with rows of erect bristles. Tibiae at the outer angle unequal, curved, the anterior widened into a tooth at the apex, with a somewhat large curved spine; tarsal segments short, claw segment strongly clavately thickened, claws simple, rather small; form of body and prothorax as in Lyctus.......................................................Minthea Pascoe.

REVISIONAL NOTES.

In the foregoing generic synopsis Trogoxylon Le Conte has been placed with Lyctus, as has been done by Colonel Casey (1891). Le Conte, in separating the genera, did so on the ground that TrogoxyIon did not have the anterior tibia prolonged at the outer apical
a The first visible ventral segment in the Lyctide is the third abdominal sternite. (See Hopkins, Tech. Ser. 17, Pt. I, Bur, Ent., U. S. Dept. Agr., p. 55, fig. 38, 1909.)

angle. As stated by Reitter, later by Casey, and as is easily seen, they are produced and in some species as strongly as in any true Lyctus. Reitter in his synopsis states that in Trogoxyilon the sides of the head are provided with three hooklike teeth, that the pronotum has all its angles sharp, and that the elytra are without rows of punctures or hairs, but that these are irregularly disposed. As a matter of fact, LYctus (Trogoxylon) imnpressus Comolli does have the three elevations mentioned, but in all the species so far recognized in the United States not only the tooth over the eye is obsolete, but the posterior angles and margin of the epistoma are closely joined to the angles of the front, so that the epistoma is but slightly depressed below the level of the front, and the two elevations seen in many species of Lyctus are not traceable-a character also observable in L. (Xylotrogus) politus n. sp. The shape of the pronotum is of little value; in L. brunneus Stephens all the angles are acute. The elytral punctures in L. (Trogoxylon) californicus Casey are decidedly striate and there is a tendency to the same thing in L. curtulus Casey.
The first visible ventral segment in most species which would fall in Trogoxylon is as long as the second and third combined, but in others it is not longer than the second and one-half of the third.
Xylotrogus has long since been shown by Wollaston (1854) and other writers to be syfionymous with Lyctus, and Trogox'lon must also be so considered, though it might well be regarded as representing a well-marked subgenus.
The species of the family Lyctide are very variable, especially in size. Well-developed individuals are frequently four or five times larger than others, the difference in size perhaps dependinglargely on food supply; for the offspring of those individuals which have bred in the same piece of wood for four, five, or six generations are very much smaller and quite different in some of the structural details from the first individuals reared. Accompanying the d(lecrease in size are found such changes as in the shape and punctation of the pronotum and the punctation and pubescence of the elytra. As a result, one must allow for much variation within the limits of the species, and characters which might be of specific importance in groups more constant in character can only be held to be individual.

SYSTEMATIC NOTES.
Genus LYCTUS Fabricius. Lyectus Fabricius, 1792, p. 502. Xylotrogus Stephens, 1830, pp. II (16-1 17. Trogoxylon Le Conte, 1861, p. 209.
Lyctus impressus ('omolli. Lyctus impresses Comolli, 1837, pp. 40-85; Seidlitz, 1875, p. 160; Erichson, 1877,
p. 17.
Trogoxylon impress (Comolli) Reitter. 1885, p. 100.
This species is the largest of the Trogoxylon group which the author has seen. It is very distinct in the quadrate prothorax and in the possession of the three elevations at the sides of the head, one over the eye, another just before it at the frontal angle, and another at the lateral angle of the epistoma.
Material examined.-A series of 5 specimens, very constant in
character, except in size. The species occurs in southern Europe, but has not as yet been recorded from the United States.
Lyctus punctatus (Le Conte). Trogoxylon punctatum Le Conte, 1866, p. 104.
Lyctus punctatus (Le Conte) Casey, 1891, pp. 13, 16.
This species is easily known by its short, broad form, coarse punctation of the pronotum and elytra, and the stiff, short, almost squamose pubescence.
Material examined.-A single specimen from Santa Rosa, Lower California, and Le Conte's type, which is from Cape San Lucas, Lower California.
Lyctus californicus Casey. Lyctus californicus Casey, 1891, p. 14.
This species is readily recognized by its elongate, highly polished body, and by the finely but definitely striated punctures of the elytra, the pubescence of which is fine and sparse. It is easily distinguished from L. curtulus, to which it is probably most closely allied, by its more slender, parallel, elongate form, finer elytral punctures, and other minor details. There is some variation in size and density of color, but other characters are quite constant.
Material examined.-A series of 5 specimens from Santa Rosa, Lower California. Colonel Casey's specimens are from Fort Yuma, Cal.

Xylotrogus parallelopipedus Melsheimer, 1844, p. 112.

Lyctus parallelopipedus (Melsheimer) Casey, 1891, p. 13.





122 MISCELLANEOUS FOREST INSECTS.

Most readily recognized by the very finely, densely, confusedly punctured elytra, with the pubescence long, dense, fine, and decumbent, and the margin of the prothorax strongly trisinuate.
There is great variation in size, as usual. The side margins of the prothorax are generally straight, sometimes slightly curved inward, and the prothoracic punctures are generally fine.
Material examined.-A series of more than 100 specimens. Distributed throughout the eastern and southeastern United States.
Lyctus curtulus Casey.
Lyctus curtulus Casey, 1891, p. 15.
One of the smaller species, easily separated from parallelopipedus Melsheimer by its coarse elytral punctation, average smaller size, and prothoracic structure, and from californicus Casey by its much shorter, robust form, denser elytral pubescence, coarser and less sinuate arrangement of elytral punctures, and in being much less shiny.
There is considerable variation, more especially in size and coloration, and likewise in the density and size of the prothoracic and elytral punctures, in the convergence of the sides of pronotum, in the sinuation of its anterior margin (the latter sometimes becoming feebly trisinuate), and in the degree of depression of the epistoma. A single specimen from Bonner, Mont., differs quite noticeably in several respects from the more typical examples of curtulus, and may represent an undescribed species. However, it is placed here until more specimens show it to be distinct.
Material examined.-A series of more than 300 specimens. Distributed throughout the soutl western ITnited States.
Lyctus politus n. sp.
Type.-Cat. No. 7432, United States National Museum; U. S. Department of Agriculture, No. 7414; one of 21 specimens collected and reared by Dr. F. II. ('hittenden from licorice at Washington, D). ('.
This species is readily separated from brunneus Stephens by its much shorter, broader formI, more shiny, finely and less densely punctured prothlorax, and by the structure of the front as outlined in theI synopsis (p. 1 18).
There is consi(lerable variation in size, and to a less extent inii the convergence of the sidles (of the i)rothorax posteriorly, and in the plr-obotal l)ulctatioll.
It is )ossibh that this species ihas been already described, but the author has heell unable to place it in any of the species of which he has had speci IHCs or oldescriptions and has, in consequence, described it as beillrg new.

1885, p. 100; Reitter, 1906, p. 423.
Lyctus caroline Casey, 1891, pp. 13-14.
This species, while allied to L. politus n. sp., is readily distinguished by its larger size and coarser structure throughout and more acute anterior angles of prothorax; the epistoma also is more depressed, its posterior angles as in planicollis Le Conte. The series of specimens is very constant, except that there is the usual variation in size and color. A single specimen from Philadelphia, Pa., is more slender, the prothorax narrower and more constricted behind, with the sides straight, and the anterior margin more strongly arcuate. It is probably best placed here for the present. A series of 3 specimens from Mr. Reitter shows considerable variations, more especially in the shape of the prothorax, and one individual has the pronotum much more coarsely punctured.
Material examined.-A series of 14 specimens. The species is
widely distributed throughout the world.

Lyctus pubescens v. caucasicus (Tournier) Reitter, 1906, p. 423.
The species is very distinct. It is perhaps more closely allied to brunneus Stephens than any other, both in elytral and prothoracic structure, though very distinct from it. It is remarkable in having the prothorax very much darker than the elytra, a character seldom met with in this family.
Material examined.-Two specimens from Mr. Reitter are labeled "Silesia, on Willow." One of them has the prothorax strongly narrowed posteriorly, the other much less, although distinctly so. The species occurs in Europe, but up to the present time it has not been recorded from the United States.
Lyctus opaculus Le Conte.
Lyctus opaculus Le Conte, 1866, p. 103; Casey, 1890, p. 324; Casey, 1891, p. 13.
This species is remarkably distinct and easily separated by the narrow, convex prothorax, the anterior angles being very broadly rounded, the side margins strongly convergent posteriorly, the surface opaque and very densely subrugosely punctured, the median

The pronotum may be densely, evenly puncturedl over the entire surface, or have the punctures less denise and the surface polished anteriorly, but is never scabrous; the median impression varies from very deep and becoming broadly expanded anteriorly, wilth a small circular impression at either sidle, to subobsolete in I lie smaller specimens.
Whether this species and carbonarius Waltl are synonymous the author can not say, since he has not seen Waltl's description. However, he has 2 specimens widch Mr. E. A. Schwarz tells him are
from Mexico, received through Dr. E. D)ughs from Guanajuat(o.
These specimens are probably from among the series on which Doctor Dughs based his "Metamorphoses du Lyctus planicollis." Tihey
differ in some of the minor details from planicollis, more especially in having the pronotal punctures coarser and less (lense; and the median impression is deep, oval, and not broadly expanded anteriorly. Should these characters prove constant in a larger series they might well be considered as representing a distinct species, probably carbonarius Waltl, very closely allied to planicollis.
Material examined.-A series of over 500 specimens. The species is found widely distributed throughout the entire United States at least.
Lyctus parvulus Casey.
Lyctus parrulus Casey, 1884, p. 175; Casey, 1890, p. 325; Casey, 1891, p. 13.
This species is remarkably distinct and is separated at once from the other species by the broad cordate prothorax and its dense, coarse, subrugose punctation.
There is great variation in size and to a less degree in the shape of the prothorax and in the acuteness of the posterior angles. In general form it resembles planicollis Le Conte, but in structural details resembles opaculus Le Conte. It is readily separated from either, and is far removed from linearis Goeze, with which species it has very little in common.
Material examined.-A series of about 50 specimens. Distributed throughout the western and southwestern United States.

NOTES ON HABITS AND DISTRIBUTION, WITH LIST OF
DESCRIBED SPECIES.a
By A. 1). HOPKINs,
In charge of Forest Insect Inrestigations.
HABITS.

So far as known, the species of the family Iyctide live in dead and dry wood of natural growth, in the seasoned sapwood of commercial products, and in the pith of vines and the dried roots of herbaceous plants, but do not infest the wood of coniferous trees.
Some of the species appear to prefer the dead and dry wood of standing trees, shrubs, and vines under natural conditions, and therefore are rarely found in the commercial articles; for this reason they are not subject to temporary or permanent removal from the natural range of the species. The other species, which infest commercial products, are subject to wide distribution over the world.
The following notes relate to species represented in the collections of the United States National Museum and United States Departniment of Agriculture, the habits of which have been observed by the writer or recorded in connection with the specimens.

The genus Lqctus has Irnatially e ,,tlae range ,s the family; the genus Lyctoxylo it seems to h ave its natural distribtion in eastern India and Asia between thle twentieth i and( fortietlh parallels north; while in the genus Mfittu (h one species is from IRo(Irirguez Island and the Philippines, with a record(l from soutlerin Europe, and the other species is from Bogota, Colombia, South Ameria.
It appears that the center of (l istrib)utition of the greatest number of species of the family is between the twentieth and fortieth parallels north in both continents.
The available evidence would intdlicate that the natural distributions of the species studlie(d by the writer are approximately as follows:

The natural distributionll of the species is evidently in the South Atlantic and Gulf States, and( in part of the Mississippi and Ohio valleys, from which it has been temporarily introduced into other States.
L. curtulus Casev.-California, Arizona, TFexas, and Guatemala. This evidently represents its natural distribution. One record from Montana indicates temporary introduction, and a recor(l from the Sandwich Ian(ls may represent a permanent introduction.





134 MISCELLANEOUS FOREST I'NSECTS.
SUBDIVISION B.
L. )olit us Kra us .-Temporarilv introduced into the District of Columbia, probably from northern Spain or Italy, from which the commercial product of licorice is exported.
L. bru nne u (Stephens) .-Paraguay, Brazil, Cuba, and Mexico. This evidently indicates the natural range of the species, from which it h ias probably been introduced and become established in Europe, Asia, Africa, and Australia. It has been recorded from South Carolina, from Philadelphia, Pa,., and from Chicago, Ill., which probably represenut temporary introductions, although it is not at all improbable that it may become permanently established in the Gulf States, especially in Florida and Texas.
L. ptd*.w ccns Panzer.-R ecorded as common in southern and mid(Ile Europe, which may be its ~atural distribution.

SUBT)1V1SION C
SECTION a3.
Subsction 1)1.
L. opaculus Le Conte.-MNichig,)an, Iowa, Nebraska, Ohio, Long Island and Staten Island, N. Y., District of Columbia, andl North Carolina. This probably represents the natural distribution, andl since the species lives in natural growth it is not likely to be distribuited out of its natural range.


L. ,oitarais Falderniain.-Caucasus, southern Ruissia.
L. ca riwoi, Le C'(on te.-C -(alifornia, several localities, wthi (loubtfuil record from Oregron.

L. pla'i ;colfi Le ('onte.-Arizona, Nevadla, Texas, and thie Gulf alldl Sonth Atlantic States. Thlis range probably represents thle naturul (list ribution of the species, but it is frequently intro(luced tempIorarily into the Northiern and11(lidle States zand evidently into other cou1ntries, since there is a (lelillite recor-d fromi Capetown, South Africa, in lumbeor froni the southern iT iited St ales.

with characters mentioned by Mr. Kraus. It is probable that there is some overlapping of the ranges of these two allied species in Florida and from Tex as to California, and that in such localities occasional specimens will be found which occui)y an intermediate position.
L. parvulus Casey.- Arizona, C "alifornia, an( Itah. This evidently indicates the natural distribution of the species.

DivisioN 1I.
SUBDIVISION D.

L. linewaris (Goeze).-This species is recorded in literature as extending over Europe, and especially England, France, and Germany, where it lives in natural growth, cordwood, etc. This evidently represents its natural habitat, from which it has been introduced in commercial wood products to many other countries of the world, but it would appear from observations and records in the United States that it becomes permanently established only in those countries with climates similar to that of central and northern Europe. The species appears to be permanently established in the States north of North Carolina, Tennessee, and Arkansas. There are a great many records from this area, including Maine, Massachusetts, New York, Pennsylvania, Virginia, West Virginia, Ohio, Indiana, Michigan, Illinois, Missouri, Iowa, and Minnesota. The specimens in the national collection show but a single record from the South Atlantic and Gulf States, and that is evidently a temporary introduction. Undoubtedly the species is frequently carried into the southern region, but evidently does not survive there.

THE GENUS LYCTOXYLON.

L. japonum Reitter.-Japan, China, and India. This probably represents the natural range of the species, from which it has been introduced into Europe, America, and other countries, possibly becoming established in those with climatic conditions similar to that of its original habitat. The recorded introductions into the United States are from China into California and Massachusetts, and probably from Japan into New Jersey.

THE GENUS MINTHEA.
M. rugicollis (Walker).-Philippine Islands, Siam, China, Ceylon, and the Malay Archipelago. This probably represents the natural habitat, from which it may have been introduced into Europe, the West Indies, and the Hawaiian Islands.
M. stichothrix (Reitter).-Bogota, Colombia, South America.
