''This seems to be a stouter and broader winged form than the European, in which it would 

 conform to Dr. Speyer's law of variation in the Noctu:>^. The outer line is less distinct than in the 

 European species, of which it may be a modification." (Harvey.) 



I have received a $ from Mr. O. S. Westcott, taken in Wisconsin, and he writes nie: " I got 

 the name Lophoptcryjs americana Harv. from Grote." I can not see that it differs from the 

 European L. cameUna. 



• Geographical distrihutioii. — Found by Mr. C. A. Blake in jMew Jersey, near rhi!adeli)hia 

 (Harvey). The following localities have been sent me by correspondents in whose collection the 

 species is contained: New Jersey (Professor French); New. Jersey, Pennsylvaiua (C. Palm); 

 Chicago (A. Bolter); Racine, Wis. (Westcott); Manhattan, Kans. (E. A. Popenoe). In Europe 

 and Asia L. camcJina ranges from central and southern Europe to Turkey, Siberia, and Amoor. 



Larva — We copy the following account from Uellms in Buckler's Larvic of British Butterflies 

 and Moths (ii, p. 1G2). 



I liave uo notes of the egg or young larva. By the time the larva is 10 mm. in lougth it has a good deal of the 

 adult appearance, colors brighter than afterward, uo red dots yet on the spiracular line. The full grown larva is 

 about 33 mm. in 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 hairs ; to use Albin's 

 words, "in 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 coloring; one mealy whitev- 

 greenish on the back, with the dorsal vessel like a blue thre.ad, a subdorsal line of a faint bluish tin"-e, tlie side 

 below more green, the spiracular line, which extends around the anal flap, yellow, edged above with violet, and 

 bearing a red spot behind each spiracle; the spiracles black, the belly green, with a tinge of plum color, and showiu"- 

 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 pink, ventral prologs green with red feet. 



Another variety had the head and sides of a pale yellowish pink, "the back after .'> more 

 whitey-pink, with a darker tinted dorsal thread;" the warts on the eighth abdominal segment full 

 deep pink, the spiracular line yellowish, with the red spots behind the black spiracles. 



This larva is remarkable for the double twinned high conical tubercles on the eighth 

 abdominal segment, whereas in Pheosia the horn is single. Possibly tlie double tubercles of 

 Lopliopiery.T cameiiiia is the primitive condition, the single hump of L. cucullhia " ending in the 

 twin points," being intermediate between the twin tubercles of L. cameUna and Pheosia. It will 

 now be a matter of great interest to discover the larva of our American Lopliopieryx clcyavs. In 

 England the food plant of L. camclinais the poplar, oak, alder, and hazel (Hellins). It should be 

 observed that the larva of the European L. carmclita is smooth, noctuiform, with no hump on the 

 eighth abdominal segment.
