at Diloxi. It was th-,e larr-est fli ,lzt that I have seen in this section. They
,,,ere flyin.1 hi4;h through the tops of thie trees and -oin- in a general northerly
direction' with the prevailing wind. No evidence of fLeoding d.a;ma. C was noticed
and hen he isectalihted on the trees, weedls, -rass, etc., they did not
ampear to feed but only to remain until a S7,ist of wind or come other disturbance caused thorn to ta:ke to the air again. The f light c6uld not be tr-ace. very far from this small farm; and the pole h ad not noticed any o7rasshopper nymphs
eu rin 7 the early part of the fall or summer. Mess,-rs. 0. T. Deen and F. A.

reports state that in some sections it was necessary to raise car windows to
1-eep thle insects from fl-hin2z into the cars as they were movin 7 along. the road.
Cn October 20 some of the same species wore noted in the extreme southern end
of Mobile County, Alabama. Thec distanod from the western Missiscippi observationa to the Alabama obse rvation was at least 75 miles. The0r-: w.as, evidently

list. In addition to feeding upon the bracken and cinihamon for., it ow
defoliates shinning sumac (Rhus copallina) and the tou.-leav s: oak
(Quercus ilicifolia). Numerous other plants characteristic o" the Pin.e Barrens
also fed upon. Grassy areas and margins furnish proper conditions for the
development of larvae throughout the pine re, ion. It is believed that

THE EFFECT OF THE HURRICANE OF SAN CYPRIAN ON INSECTS IN PUERTO RICO
G. N. Wolcott
Insular Experiment Station, Rio Piedras, Puerto Rico
The north coast of Puerto Rico was swept by a hurricane on the night of September 26, 1932, the violence of which continued for four or five hours into the morning of the 27th. The direction of the wind was almost entirely from the north and northeast; it veered to the south less than half an hour before decreasing greatly in intensity. Only sligJtly less than the reported maximum velocity of 160 miles per hour was maintained throughout most of the period of the hurricane.
The effect of the hurricane on many insects presumably will not be marked;
those which are subterranean, for instance, being but little affected by the high wind, while the rainfall accompanying was no more than the precipitation of many an ordinary storm. On the first night after the hurricane a May beetle, Phyllophaga nortoricensis Smyth, was noted at candlelight on the second story of a house in Rio Piedras, and on the following night two black "hard-back" beetles, DyscinetL-s barbatus Fab.,were found under similar conditions. The entrances of ant nests in the ground were noted as being open by the second morning; and while the food supply of the ants may differ from normal, it should not lack for quantity. .nts living in trees may, however, suffer a temporary loss in population, as branches weakened by their tunnels would presumably be most easily wrenched off by the wind. Siilarly, insects living within plant tissue are but little affected, the caterpillars of the sugarcane borer, Diatraea saccharalis Fab., being uninjured, even when the cane itself is flat on the ground.
Despite the almost total defoliation of most trees, leaf-feeding insects appear to be present in normal abundance, more adults of the common large otiorhynchid:beetle Dia-reces abbreviatus L. having been noted in citrus nurseries at Rio Piedras and Bayamon a few days later than had previously been observed in several months. Even such apparently fragile insects as butterflies may not ha e been much affected, except as their-habitat may have. temporarily been changed, a zebra butterfly, Heliconius charitonius L., for instance, having been noted flying about in the nlaza at Rio Piedras far from the Woodland glades it usually frequents.
The insects feeding on dead or dying wood, on or under dead leaves, and on rotting fruit will of course have enormously increased supplies of food available for their consumption, at least terporarily, but practically none after the supply at present available disappears, and a corresponding, fluctuation in their abundance may be anticipated.
As regards the natural enemies of insects, considerable numbers of dead toads have been noted since the hurricane, but these stupid anima ls are so often run over by automobiles under normal conditions that the observed mortality may be little more than would have occurred during heavy rainfall unaccompanied by high wind. In-defoliated'citrus groves birds seem much more numerous than formerly, for they are not accustomed to the absence of leaves, and take no precautions to remain hidden; even if that were possible. So .far as observed, there has been no great mortality among them, despite that reported after previous storms. For
instance, Van Zwaluwenburg, quoting Barrett, states that the changa, Sca-oteriscus
vicinus Scudder, "has been very troublesome in Puerto Rizo only since the hurricane of 1876, which is supposed to have destroyed most of the insect's bird onemies. After 1885 the insect seemed to decrease slightly in numbers until the hurricane of August, 1899."
Surprisingly enough, the insects most directly affected by the hurricane are the scale insects. The trunks and branches of trees exposed to the full force of the Wind are smoothed of rough bark and all projections in a most surprising manner. Of course some scales persist in the crotches and on the retioles of leaves, but the breaking off of leaves, twigs, and large branches causes an immediate decrease in their numbers only exceeded by the mortlity caused by the direct action of thc wind and rain in rubbing the insects from their host. Despite the temporary very great decrease in the number of scale insects, in the case of the cottonycushion scale, Icerya curchasi Mask., the ultimate effect of the hurricane will be to greatly extend its -oreviously restricted range. Previous to the hurricane, its distribution was largely limited to casuarinas and citrus trees in San Juan and Santurce, and to citrus groves along the coast to a little west of Dorado, extending inland only to Pueblo Viejo and Bayamnon in small and scattered infestations. Owing to the effect of the fungus in the summer, and more recently to the greatly increased numbers of Australian lady beetles, (Vedalia) Rodolia cardinalis Mulsant, both in citrus groves and on casu-arina tres, coupled W;ith effective spraying, the numbers of this new pest had been greatly reduced. Since the hurricane, only a few small scales can be found on the trees previously even most heavily infested, but as this foreign scale can thrive on many kinds of native trees and -oplants, its distribution has presumably been greatly extended to the south and West of its former range.
Specimens of a scale (tentatively identified by me as Saissetia oleao Bern.) are very aoundant on a considerable number of Ficus so trees along the road south from Fajardo, blackening their branches and in some cases causing considerable defoliation. I do not n-oreviously remember having noted this scale in such large numbers and on so many trees. As to the species of Ficus, it is not nitida and not lacvigata.

The moth borer Azochis griousalis Talk. was harmful during the entire year to figs, discouraging the growing of this fruit. Adults are still emerging (Augu t 13) from caterpillars that I have been rearing; since May 28. The old borings are often occupied by families of earwigs. This moth borer is beginning to become serious again, on fig, October 8. San Pedro de Montes. de Oca. (Det. Schaus.)
Moths of Stenoma sororia Zell. are very bad; caterpillars fasten leaves togeth er and eat between and bore into buds and tender twigs; -ounae between leaves; observed May 28 to August 13, San Pedro de Montes do Oca. (Det. A, '3usck.) August 13 to October 8 the caterpillars of this'insect were abundant and harmful, causing the death',f twigs of avocado at San Pedro de Montes d6 Oca.
A tent-caterrillar, Stericta albifasciata Druce, has been found on avocado at San Pedro de Montes de Oca; the tents were small, nrobab i because I discovered them and-destroyed them before they had done much damage. Puoae covered with soil are on the surface of the soil. (August 13.) (Det. Schaus.)
The.tent caterpillar Jocara subcuroalis Schs. ? appears to be more harmful than Stericta albifasciata Druce, defoliatin: and destroying tender bark on small branches and causing loss of branch. Pupae in leaf trash. June 24 to August 13. San Pedro de Monteg de Oca. (bet. Schaus.)

The moth Bythyena colhodes Tals. is not serious; cater-illars and pupae
are scattered mostly on outer leaves of avocado; naked putae on upser surface of leaves. Observed at San Pedro de Montes de Oca from May 10 to September,' the caterpillar of this insect was usually present but not numerous on avocado and rather hard to collect because it feeds unon leaves on rather inaccessible branches. (Det. Busck.)
The moth borer Hypsipyla grandella Zell. destroys the greater Oart of young cedar trees at the school at San'Pedro de Montes de Oca before they attain 1 meter height.. Larvaehave been" abundant since first observed June 27 until the present time,' September 9. More adults of the moth borer have emerged. It prefers C. montana var. mexicana Turcz. to C. glaziovii var. puberula C.DC. (Det. C. Heinrich.)
Three specimens of moths reared from the leaves of roble da sabana, Couralia rosea Donnell-Snm., San Pedro do Montes de Oca, July, determined by U. Schaus as Mesocondyla concordalis Hbn. August 13 to September 8 more adults of the leafeating cater-oillar have emerged on C. rosea. This cater-oillar is very harmful to C. rose. (October 8.)
A cicadellid, Cicadella areolata Sign., is usually found on arrowroot, but does little if any damage. It is a frequent visitor to bean plants and also feeds on caiba (Cyclanthera pedata Schrad., farn. Cucurbitaceae), San Pedro de Montes de Oca. On a young tree in Paso Ancho de San Sebastian the tender young leaves of orange were injured by it. C. areolata is also found on pitanga (EUgenia uniflora), August 13 to Sertember 8. This insect feeds on the leaves of aguacatillo (Fhoebe tonduzii), a-tree we are trying out as a stock for avocado, but the' insect is not imrDortant, San Pedro de Montes de Oca. It has been taken on dhlia at Taranja; feeds on the leaves of malacca pear (Eugenia malaccensis) without doing much damage. (October'8'.)
Cicadqlla nardalina-Fowl. feeds upon the leaves of malacca oear without doing much damage. It is injurious on tender shoots of pear, and breeds on poro (Erythrina rubrinervia). October 8. This insect is also found on cashew, but is never abundant.' It is a pest of some importance on quince. (August 13 to September 8.)
