posterior line double, obliterate, with included paler shades which traverse the wing obli(|Hdy, 

 marked on costal region; a series of anteapical pale dots; purplish brown subtermiual shade. 

 Median space diffused, shaded with puri)lish brown, more appareutly so before the outer line, and 

 interiorly where the median lines approximate; a terminal brown line, interrujjted on the veins 

 o]jposite to the extremities of which the exserted 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 primaries 

 before apices repeated; fringe brown. Body rusty brown. Tooth on internal margin of primaries 

 not prominent. Exjianse, 36 mm. Collection Buff. Soc. Nat. Sci." 



''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 Noctua% The outer line is less distinct than in the 

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



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

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

 European L. camelhia. 



Geographical distribution. — Found by Mr. C. A. JJlake m New Jersey, near Philadel|)hia 

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

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

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

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



Larva — We copy the following account from Hellins in Buckler's Larvse of British Butterflies 

 and Moths (ii, p. 102). 



I have no notes of tlio egg or young larva. By the time the larva is 10 ram. in length it has a good deal of the 

 adnlt appearance, colors brighter than afterward, no red dots yet on the spiracular line. The full grown larva is 

 about 3;^ mm. in length, stout in figure, tapormg slightly forward, the head much deeper and a little wider than 2; 

 there arc no humps ; on 12 a pair of very prominent warts, the places of the usual dots marked by hairs ; 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 coloring; one mealy whitey- 

 grecuish on the back, with the dorsal vessel like a blue thread, a subdorsal line of a faint bluish tinge, t)ie 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 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 pink, ventral prolegs green with red feet. 



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

 whitey-i)ink, 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 the double tubercles of 

 Lophoptcryx camelina is the primitive condition, the single hump of L. cuenllina " ending in the 

 twin points," being intermeiliate between the twin tubercles of L. camelina and Pheosia. It will 

 now be a matter of great interest to discover the larva of our American Lophopieryx elet/anK. In 

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

 observed that the larva of the Euroiieau L. carmelita is smooth, uoctuiform, with no hump on the 

 eighth abdominal segment.
