of this city, -iowilng that the attack wa- not local. although more
severe on the d(lepartmient grounds, which had iattracted Ihe ibut-
terflies from afar, doubtlies- owing to tlie much?
larger parkage. Caterpillar-. kept iiiiunder observa-
tion had "spun up" for pipiiation 1v September

larva, present in garden f)lat,. and there was
evidence that they hi:ald I een at w\vrk at least a-
late as the middle of .i\i.t, while the age of the
larva indicated that the butterflic- lia1 appeared
to lay their e,,, late in Jily. but evidently not
t earlier. The cau:-e of tiil- i nva-ion was appar-
*en ent(1 that the snmiiier of 1905. was an unusually
hot one. Heat fa\vor- :in increase of iriects of
this type. Prevailing -,itlerly winiid-, however,
S were probably miore potent factors in causing

a] il,,ighli it inhabits also the extreme Soutitherni State.- of our Union.
So far as can be learned it is known to exist permanently only in
the Gulf Statet. South Carolina. and Porto Rico in our domains. It
also inhabits Cuba and Jainaica, liowever, andi in South America
occurs as far south as Argentina, where it was years ago reported to
lIe common by Burmeister.
In an earlier article on this species (loc. cit.), SeCidder's dictum was
followed and the mentioned occurrence of this -pecies at Bay Ridge,
T.,niig Island. and at New York City were considered as merely tran-
sitory. It is evident that such infestations mi'v occur in the North
whenever conditions favor the iiorthwiliard flighli of tlie butterfly.
These conditions have been mentioned. It i1 hardly probable that
the insect successfully overwinteis in the District of Columbia or

are favorable conditions for such i flight. Careful search was made
by the writer in the parks of New Yorkl City in September and Octo-

was no evidence whatever of tlhe presence of this species in the State
