NORTH AMERICAN LEPIDOPTERA. 181 



twelve or fourteen days after transformation." 1 have taken the 

 insect in Brooklyn in September. I have specimens from Texas, 

 taken in April, May, June and September. In Texas, therefore, it 

 may be, and probably is, two-brooded. Mrs. Fernald took the insect 

 from June 24th to July 23d, at Amherst, Mass. Prof Forbes 

 writes me he has taken the imago at electric light on July 20th and 

 August 16th, at Champaign, 111. 



2. C liaminoiicli Riley, Mo. Rep. iv, 46, fig. 21, 1872 (Pempelia) ; Index 

 Mo. Rep. p. 80, 18S1 ; 111. Rep. xv, 252. 1877; Weed, 111. Rep. xv, p. 58.— Average 

 expanse 12 mm. Fore wings glossy purplish brown, with two silvery gray trans- 

 verse bands, dividing the wing on costa in about three equal parts; the basal 

 band sharply defined outwardly, and always extending to inner margin, the pos- 

 terior band never extending more than half way acro.ss the wing, and generally 

 not more than one-third, illy-defined. In some specimens the basal band is quite 

 narrow, with the basal -shade paler than the median ; in others the band forms 

 a double line. In some specimens also a narrow, pale, transverse line outside the 

 second band, and a pale terminal shade are visible. Hind wings uniformly paler 

 gray. Under surface glossy gray with no marks, the front wings a shade darker 

 than the hind. 



Larva. — Length 11 — 12.5 mm. General color olive or pale green, or brown, 

 with a broad dark stripe along each side of back. Tapers slightly both ways, 

 joints 4 — 12 inclusive, divided into two transverse folds; freckled with numerous 

 pale specks and with piliferous spots, the specks often taking the form of two 

 pale broken lines along the upper edge of dark stripe. The piliferous spots are 

 pale with a central black dot, and are best seen in dark specimens. On joints 

 4 — 12 inclusive, there are placed 4 in a square in the middle of the back, and 4 

 more each side, the two upper lateral ones being on the anterior fold, the stig- 

 mata appearing as minute rufous specks between them. Both these spots are 

 often double. The third lateral spot is on the posterior fold, and the fourth is 

 subventral and anterior. The hairs proceeding from these spots are long and 

 setaceous. Head horizontal, freckled, pale behind, tinged with green in front 

 and with a few long hairs; joint 1 also freckled, and with a large black pilifer^ 

 ous tubercle, with a pale basal annulation, and in range with middle of dark 

 stripe, joint 2 with similar black tubercles, with a white center and replacing 

 the uppermost lateral pale spot. There are but two of the small, pale, dorsal 

 piliferous spots on this joint (between the tubei'cles). as well as on joint 3. Be- 

 neath immaculate, except that the thoracic legs have sometimes a few dusky 

 dots. In very dark specimens the head, cervical shield, and anal plate remain 

 pale. The cervical shield is then well defined, with four piliferous specks at an- 

 terior edge, and the large shiny tubercle forms the extreme anterior angle. 



Pupa. — Length 6 mm. Rather short and stout, with two diverging spines and 

 a few stiff bristles at tip. 



In many specimens the subdorsal dark stripe is obsolete or siibob- 

 solete, but even then the four black tubercles on joints 1 and 2 char- 

 acterize the larva sufficiently (from Riley). 



Pi'of Forbes took this insect at electric light July 2oth.
