464 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION 



•whitish, surronndecl with a black border. There is a row of stout, heavy filaments 

 just above the line of the legs. No protuberauces appear on the dorsal aspect of any 

 of the rings. Length. 2.2 inches. 



Pupa. — Pruiuose, abdominal tip black, bearing eight hooked hairs, the four upper 

 smaller ones turn toward the median line, the four under are larger and turn away 

 from it. (Kellicott.) 



Moth. — Forewings very light gray, heavily powdered and shaded with black 

 •atoms; the base, reniform spot, and terminal space, especially heavily shaded; trans- 

 verse anterior line geminate, diffuse; transverse posterior line rather heavy; M not 

 very strong, the line below dentate ; subreniform white ; a diffuse white spot beyond 

 the reniform spot; subtermiual line white, dentate. Hind wings red, somewhat 

 ghaded at base, with black median band strong, reaching the anal margin ; marginal 

 band broad. Expands 80 to 85™™. C. fucilla Worthington does not differ from this. 



Var. mefkei Grote. Forewings somewhat lighter than unijuga; hind wings with 

 median and marginal bands narrower, the former not reaching the anal margin. 



Var. beaniana Grote. Forewings darker than in unijuga; hind wings with the 

 median band more even, not reaching the anal margin. (Hulst.) 



40. Catoeala cava Guen^e. 



The caterpillar of this fine moth feeds on the willow, according to Mr. 

 Koebele. In Papilio (ii, p. 167) Professor French has given a full life- 

 history of the insect. It molts four times. The eggs were deposited 

 October 6, the larvae feeding on the willow ; the young hatched April 

 6, and became full-fed, spinning their cocoon May 11 to 20, the moths 

 emerging June 23 to 26, but when not in confinement the moth is not 

 «een until the 1st of August. 



Egg. — Diameter .04 inch, nearly globular ; top a little depressed, containing a little 

 button. (French.) 



Larva. — Head gray brown; protuberance on the summit of the eyes prominent. Body 

 with ground color gray ; very heavily marked and striated with rust-brown, which 

 towards the head almost completely covers the body. There is a brown lunule on 

 the eleventh segment with horns forwards. Underneath clear red-brown between the 

 third and sixth segments. The sixth and seventh segments between and in front of 

 the legs have each a large nearly round spot. The larva is considerably smaller than 

 that of C. ilia when full-grown, though the moth is one of the largest, if not the 

 largest, of all Catocalse. (Koebele, Bull. Brook. Ent. Soc, iv., p. 22.) 



Pupa. — Of the usual shape. Dark brown, covered as usual with a white bloom. 

 Abdomen finely punctured, the tip of the last joint very coarsely so. This ends in 

 four hooks, two longer than the others, while there are two more hooks arising 

 from the punctured portion at a little distance from the four. Length 1.45 inches. 

 (French.) 



Moth. — Forewings deep blackish brown ; lines narrow, distinct anteriorly ; lines 

 and veins shaded with olivaceous. Hind wings intense rose-red, with a broad even 

 black median band reaching the oval margin. Expands 85 to 95™™. Middle and 

 Eastern States and northward. 



Var. carissima Hulst. Forewings rich velvety brown, spotted and flecked with 

 olivaceous scales, which form a large spot at the apex. Expands 90 to 100™"'. Habi- 

 tat, south and east from C. cava. C. sylvia is slightly more spotted with olivaceous, 

 (Hulst.) 



41. Catoeala parta Men6e. 



This species has been bred from Populus dilatata by Mr. Thaxter 

 (Psyche, ii, p. 35), but he has given no description of the caterpillar.
