posterior line double, obliterate, ^itli iucluded paler shades \vliicb traverse tlie wing obliquely, 
marked on costal region; a series of anteapical pale dots; purplish brown subtenninal shade. 
Median space diffused, shaded with purplish brown, more apparently so before the outer line, and 
inferiorly where the median lines approximate; a terminal brown line, interrupted on the veins 
opposite to the extremities of which the cxscrted fringe is dark brown. Hind wings ochery, with 
concolorous fringes, becoming brown toward anal angles ; a median pale shade, which intersects at 
internal margin a blackish patch. Beneath, yellowish immaculate, the dots on costa of [ulmaries 
before apices repeated; fringe brown. Body rusty brown. Tooth on internal margin of primaries 
not prominent. Expanse, 36 mm. Collection Buff*. Soc. Xat. Sci.’^ 
‘^Tliis seems to be a stouter and broader M'inged form than the European, in which it would 
conform to Dr. Speyer’s law of variation in the iSoctum. The outer line is less distinct than iu the 
European species, of whicli it may be a modiflcatiou.” (Harvey.) 
I have received a 5 from Mr. O. S. Westcott, taken iu Wisconsin, and he writes me: “ I got 
the name Lopltoiiteryx americana Ilarv. from Grotc.” I can not see that it dilfers from the 
European L. cameUna. 
Geographical dintrihntion. — Found by Mr. C. A. Blake iu ^ew Jersey, near Philadelphia 
(Harvey), The following localities have been sent me by correspondents iu whose collection the 
species is contained: I^ew Jersey (Professor French); IN'ew Jersey, Pennsylvania (G. Palm); 
Chicago (A. Bolter); Racine, Wis. (Westcott); Manhattan, Kans. (E. A. Popeiioe). In Europe 
and Asia L. camelhia ranges from central and southern Bnroxie to Turkey, Siberia, and Amoor. 
Larva — We copy the following account from Hellins iii Buckler’s Larvie of British Butterflies 
and Moths (ii, p. 162). 
I liJive no notes of the egg or yonng larva. By the time the larva is 10 mm. iu length it has a good deal of the 
adult appearance, colors brighter than afterward, 110 red dots yet on the spiraciilar liuo. The full growu larva is 
about 33 mm. lu length, stout in figure, tapering slightly forward, the head much deeper and a little wider than 2; 
there are no humps; on 12 a pair of very prominent warts, the places of the usual dots marked by liairs; to use Albin’s 
words, “ill repose it always lifts up its hinder part,’’ and also throws back its front part till the back of the head 
and segment 2 are quite bent over segments 5 and 6. There are several varieties of cploriiig; one mealy whitey- 
greeuisli on the back, with the dorsal vessel like a blue thread, a sulxlorsal lino of a fi^iut bluish tinge, the side 
htdow more green, the spiracular Ime, which extends around the aunl flap, yellow, edged above with violet, and 
bearing a red spot behind each spiracle; the spir.acles black, the holly green, with a tinge of plum color, and showing 
the usual ventral dots distinctly of a pale yellow, the head smooth, green, the mouth yellow, with a black line, the 
warts on 12 bright red, thoracic legs piuk, ventral prolegs green with red feet. 
Another variety had the head and sides of a pale yellowish pink, ^^the back after 3 more 
whitey-pink, with a darker tinted dorsal thread;” the warts on the eighth abdominal segment full 
deep pink, the spiracular line yellowish, witli the red spots behind the black spiracles. 
Tliis larva is remarkable for the double twinned lugh conical tubercles on the eighth 
abdominal segment, whereas in Pheosia the horn is single. Possibly the double tubercles of 
Lopliopteryx camelina is the prijiiitive condition, the single hump of L, cncullina “ending in the 
twin points,” being intermediate between the twin tubercles of L, camelina. and Pheo.sia. It will 
now be a matter of great interest to discover the larva of our American Lophopieryx eleyann. In 
England the food plant of L, camelina is the poplar, oak, alder, and hazel (Hellins). It should be 
observed that the larva of the European L. carmelita is smooth, noctuiform, with no hump on the 
eighth abdominal segment.
