whitish, sharply marked from the dorsal color. Warts l)lack, ii, iii, 

 V, and vi large, i small, all many haired except i and v, which have 

 only two or three hairs, iv a tiny rudiment behind the spiracle, just 

 perceptible. Joint 2 much contracted, the cervical shield indistinct; 

 joint 3 a little elevated above 2. Thoracic warts as before; lib quite 

 visible. 



Stage IV. — Head ])ilobed, full, shining- pale luteous, a black spot on 

 each lobe before, one in clj'peus, a streak in the vertical suture, and 

 ocelli narrowly black; mouth only slightly brown; Avidth, 1.2 mm. 

 BodA' nearh' black, a faint, pale luteous subdorsal and suliventral ])and, 

 straight and even, the subventral the broader, both obscure. Joint 2 

 much contracted, the long hairs of 3 overhanging the head. Other 

 hair moderate, black and white. Warts large, arctiiform, many 

 haired except iv, which is obsolete. Wart i large, smaller than ii; 

 iii largest of all. Warts dark gray, with black hair-tubercles. All 

 feet black. 



Stage Y. — Head full and rounded, scarcely at all bilobed, very pale 

 luteous brown, the small clypeus and a transverse band adjoining it 

 and nearly covering ocelli as well as vertical suture narrowly and 

 posterior edge of occiput, black; labrum. antenna?, and mouth pale; 

 width, l.S mm. Body black, venter gra}^, as also joint 2, which is 

 nearly without hairs except subventrally ; cervical shield shining, small. 

 Lines all obsolete, subventral fold a little pale; throracic feet partly 

 black, abdominal ones pale. Warts large, black; hairs black and 

 white, moderate, a group of longer ones overhanging the head. 

 Another had the head pale, a tiny brown spot on the face of each lobe 

 and apex of clypeus; the two groups of ocelli narrowly black and a 

 line in the vertical suture. The warts are large, except i\', which is 

 a nearly hairless rudiment. Later black, subdorsal line faintly trace- 

 able, pale brownish, subventral line whitish in a broad pale gray area 

 that extends from wart iv to venter. As the body pales further with 

 growth, a dark dorsal line appears and shades below the subdorsal and 

 above the subventral stripes. 



Stage YL — Head round, full, rather large, not bilobed; clypeus 

 small, shining reddish luteous, marked with black as before; para- 

 clypeal pieces pale; width 2.6 mm. Body arctiiform, joint 2 con- 

 tracted; warts large, low, black, iv obsolete. Dorsum dark gra}-, 

 with shaded black dorsal line; subdorsal line distinct, bright orange 

 shaded, especially posteriorly on the segments, sides black; substig- 

 matal line pale yellow, a little transversely streaked, like the subdorsal 

 one; venter gray; feet very pale. The long hairs of joints 3 and -t 

 (from the large warts ia+ib+iia and iv+v) and joints 12 (from 

 wart ii) and 13 (from warts i, ii, and anal plate warts) are black; 

 those from the rest of the body paler, from i to iii slightly penciled;
