168 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



chitiaous setie whicli are incurved at the end. The basal abdominal suture is well 

 marked, being very deep. Length 20""". 



Moth. — This species is the American analogue of the European A.psi, It constantly 

 diifers from its ally by the paler color of the fore wings, which are more sparsely 

 covered with scales, and by their somewhat squarer shape. The reniform spot on 

 the disc shows a bright testaceous tinge, and the ordinary spots are less approximate 

 than in A. psi. The secondaries are dark gray, nearly uuicolorous, a little paler in 

 the male, and darker in either sex than its European analogue. Expanse of wings 

 L40 inches. (G. and R.) 



226. Apatela lobelice (Guen6e.) 



This caterpillar was found by Mr. Coquillett ou the burr oak in Illi- 

 nois, June 6 ; it spun a cocoon June 22, the moth appearing July 14. 



Larva. — Body bluish-gray, the dorsal space tinged with yellow; a dorsal and subdor- 

 sal pale yellowish line extending only to segment 11, which is humped, the top bluish, 

 and on it are four quite large piliferous spots; the top of segment 4 bluish, inter- 

 rupting the dorsal line; piliferous spots whitish, prominent, each bearing a black 

 hair; sides of the body quite thickly covered with whitish hairs; spiracles white, 

 encircled with black ; body beneath greenish white. Head gray, dotted with black, 

 and marked on the top with two blood-red spots. Length 1.50 inches. (Coquillett, 

 Papilio, i, 6.) 



Moth. — Fore wings oblong, somewhat square, of a clear ash, finely speckled, with a 

 thick basal line, the transverse inferior line thick, and the superior one more feeble 

 and black, ordinary lines quite well marked. The spots not distinct, joined together 

 by a thick black spot; the orbicular spot relatively small. Fringe plainly spotted 

 with black. Hind wings dirty white, a little irised, with the veins and the edge 

 broadly washed with blackish ; beneath white, with a basal dash, a large triangular 

 spot, an interrupted transverse line and distinct terminal black dashes. Female with 

 the fore wings relatively rather large, the hind wings more obscure, with the line on 

 the under side more entire. Expanse of wings 55 '"^ (2.20 inches). (Quen^e.) 



227. Apatela afflicta Grote. 



Several caterpillars were observed feeding on the red oak by Mr. 

 Thaxter. They spun stout, elongated cocoons September 17 to 25, and 

 the moths appeared in June and July of the following year. 



Larva. — Light yellow-brown, tinged with green, darker above. A few lateral whit- 

 ish hairs. Stigmata white, ringed with black. A whitish stigmatal line; a distinct, 

 continuous black dorsal line. A subdorsal row of stiff club-shaped hairs, such as are 

 found in the larva of d. funeralis, but much smaller and not noticeable. These are 

 easily broken and in the specimens before me are present only on segments 4, 5, 6, and 

 11, though in more perfect specimens they may occur on all the segments. Oue 

 specimen found was rich yellow-green, and all vary considerably in shade. Head 

 stout, flattened behind, yellow-brown, lighter externally, sparsely clothed with whit- 

 ish hairs. It rests with the head touching the posterior segments, selecting a withered 

 or discolored leaf on which it is well concealed. (R. Thaxter in Papilio, iii, 17.) 



Moth. — Fore wings dark gray, shaded with black. The basal and transverse anterior 

 lines are black, geminate, undulate. The median space dark gray, lighter on the 

 costa and along internal margin, and traversed by the median shade-line, which is 

 black, dentate, crosses the reniform spot, and is composed of three distinct black 

 bands, which are obscured iu the center of the wing, and only apparent on the costa and 

 internal margin. Discal space occupied by a deep, blackish shade, showing a some- 

 what greenish reflection, and which occupies all the subterminal space. The ordinary 

 spots are of the normal shape ; the orbicular spot distinct, whitish with black center;
