segment witb slight central reddish portion; lateral black shading on 5th and 6th 

 abdominal segments extending down ever prolegs; a black lunate mark on rear 

 of 8th segment dorsally; tubercles red-brown. Beneath whitish with black patches. 

 Length, 20 mm. 



Stage IV. Head pale, apex of lobes orange, this color extending downward 

 to the region of the ocelli, the whole frontal area bordered by an encircling black 

 band. Body smooth, slender, pale purple-brown with orange tubercles of which 

 II is the largest, especially on the rear segments; dorsal stripe of previous stage 

 shows strong central brown marbling; the lateral stripes are more or less lost in 

 the brown marbling which is responsible for the general body-color, traces of the 

 defining darker lines may be found in longitudinal rows of dark dots; a prominent 

 pale orange transverse wart with brown basal shading on 5th abdominal segment; 

 laterad to this orange brown shading extends obliquely backward over rear portion 

 of 5th and front portion of 6th segments; prolegs pale ochreous, shaded with brown 

 on the contiguous sides; claspers bordered inwardly with blackish; lunate mark 

 on 8th abdominal segment orange-brown bordered posteriorly with blackish; 

 tubercles prominently orange; spiracles situated in a pale area, black rimmed. 

 Length, 35 mm. 



Stage V . Very similar to the preceding stage. Color pale brown. The lateral 

 oblique patch of brown on 5th and 6th abdominal segments has almost disappeared, 

 when present it is a pale suffused brown, scarcely deeper than the ground-color, 

 crossed by slightly darker shade-lines; filaments whitish. Length, 55 mm. 



Food-plant: Willow. 



We received a large number of ova laid by typical faustina and 

 the forms diantha, verecunda and zillah. The species seems quite 

 difficult to breed and we had success only with those larva? which 

 hatched earliest and were fed on billow-catkins; the parent of 

 these was a 9 diantha and the resulting progeny was about 

 equally divided between diantha and verecunda; larvae of the 

 other forms attained maturity in numbers but died before pupa- 

 tion ; we could see nothing in the larvse to warrant the supposition 

 that faustina is distinct from verecunda as a species; the eggs 

 hatch over a very extended period and when the first imagines 

 appeared in June we still had young larvse in the first stage. 



Catocala californica Edw. 



Ovum. Not distinguishable from that of C. faustina, deep purple-brown blotched 

 ap'cally with yellowish and with a yellowish central band. 



Stage I. Head pale brown; body dark greenish with three pale lateral stripes; 

 scarcely to be distinguished from that of faustina. Length, 5 mm. 



Stage II. Head pale, very strongly marked with black. Body greenish-black, 

 deepening in color posteriorly, with pale broad irregularly edged dorsal stripe 

 and three pale waved lateral lines; small black transverse wart on 5th abdominal
