brown shading is more extensive, covering the body except snbdorsally 

 on (5, 7, 10, and 11 in ring spots aronnd warts II, in little streaks in the 

 incisures and subventrally in a broad band which is narrowed at wart 

 V and forms a series of intersegmental lunate patches. These marks 

 are white. Hair black and white,, spiny. 



Stage IV. — Head black, labrum pale; width, 1 mm. Body brown- 

 black, slightly mottled with whitish, the subdorsal patclies nearly 

 ahsent, but the substigmatal band distinct as before. Hair mostly 

 whitish, only a few dusky, stiff", bristly. 



Stage V. — Head black; width 1.3 mm. Body as before. 



Stage VI. — Head, 2.4 mm. Body brown-black, a little speckled with 

 white, especially snbdorsally; abroad substigmatal band of interseg- 

 mental lunate spots white. Warts black. 



Stage VII. — Head scarcely bilobed, black; width, 3.7 mm. Body 

 velvety black, mottled with yellow dots, which segregate into a series 

 of irregularly shaped patches snbdorsally on the posterior i)art of the 

 segments and in the incisures. A broad, yellow stigmatal band, deeply 

 incised at the spiracles and narrowly cut by wart V into a series of 

 lunate patches on joints 2 to V2. Spiracles white. Warts black; 

 hair short, bristly, a few long ones at the extremities and a very few 

 fine short feathery hairs from warts I to III on joints 5 to 10. These 

 feathery hairs may be absent and are never conspicuous. From this 

 more generalized form there is a wide variation ; the warts may be 

 deep red, or situated in a series of broad, transverse red bands, reach- 

 ing across to the spiracles on each segment. The yellow marks may 

 be very much increased, the substigmatal band broadened and con- 

 tinuous, the subdorsal spots forming a continuous mottled stripe. 



Cocoon. — Spun tightly among leaves; composed of silk. 



Pupa. — Cylindrical, terminal abdominal segments rapidly tapering. 

 Segments coarsely tubercular granular, except the smooth, raised pos- 

 terior margin. Cases shagreened and grooved, nearly smooth. Color 

 brown, not blackish. Cremaster flattened, broad, concave below, slightly 

 tubercular, with a more distinct tubeicle or short spine on each outer 

 corner. Tuft of spines rather narrow, but fine; sparse, as if partly 

 absent, not concealing the end of the cremaster. 



Food plants. — Buttonbush, willow, alder, strawberry, raspberry, etc.

Ground color white or nearly so, very densely powdered witli black, 

 so that the insect obtains a bluish gray appearance. Head and thorax 

 without distinct markings, but with a tendency to a dusky line on tl)e 

 patagiae. Primaries with all the markings obscured. The basal and 

 transverse anterior lines are very feebly marked on the costa and some- 

 times entirely wanting. There is a bare indication of the median shade
