570 FIFTH REPORT OF THE ENTOMOLOGICAL COMMLSSION. 



departure from the usual structure auil habits of a numerous familjof 

 moths, the end of the papa being specially adapted for a residence in a 

 cocoon to prevent its being shaken out of its exposed pupal abode. 

 Like all tree-feeding Xoctuidje, the caterpillar is well protected from 

 observation by its style of coloration, in the present case the pale 

 green assimilating it to the leaves among which it feeds. 



25. Catocala parta Gneu. 



The caterpillar has been reared from the willow by Mr. A. W. P. 

 Cramer and described in Papilio (iii, p. 24) by Mr. Henry Edwards. 



Mr. Hulst states that it feeds ou the poplar, but on whose authority 

 is not stated. Mr. Thaxter, however, has bred it from the willow. 



Larva. — Dull fawn color. Head, as in all the genus, flattened on tbe top, with a 

 deep frontal sinus. A black line surrounds the head, except at the junction with 

 the second segment. There is a pale brownish dorsal line, and a subdorsal one, 

 slightly waved, on each segment, and inclosing a darker space. These lines are 

 most apparent at the junction of the segments. A rather broad, brownish lateral 

 line, slightly waved, incloses the spiracles, which are brown. Feet and legs cou- 

 colorous with the body. At the extreme lateral edge is a row of short sharp cilise. 

 Length, 2.80 inch. (H. Edwards.) 



j^oth. — Forewiugs close smooth even bluish gray, with basal, apical, and sinus 

 shadings; lines fine, but distinct ; |V| of transverse posterior line produced, a white 

 band from within reniform, extending obliquely outward, including the subreni- 

 form, not reaching the inner margin. Hind wings rather dull red, median baud 

 even, curved, not reaching the inner margin. Expands 80 to SS""". Eastern United 

 States. 



Var. perplexa is slightly more shaded with blue and lighter. 



Yar. pet ulans Hulst has yellow hind wings, with just a shading of reddish along 

 the anal margin. (Hulst.) 



26. Catocala concumbens Walker. 



This has been bred by Mr. Saunders from the willow ; Hulst adds 

 the poplar as also forming its food-plant. 



Larva. — Head flat, dark grayish intermixed with red. Upper surface dirty brown 

 with a lightish chain-like dorsal stripe and a very small fleshy protuberance on each 

 side of this stripe on each segment. Ou the ninth segment is a small protuberance 

 of a brownish color and on the eleventh a mark resembling an oblique incision. A 

 thick lateral fringe of short hair close to the under surface ; the latter pinkish with 

 a central row of round black spots which are larger about the middle of the body 

 and much smaller towards the extremities. (Saunders.) Length, 2 to 2.50 inches. 



Moth.— Foresvings pale violaceous brown, mixed with gray, lightest towards the 

 costa; lines fine, but distinct ; reniform vague, whitish, pale brown within. Hind 

 wings bright pink; median band very broad, rapidly narrowing towards the anal 

 margin, which it does not reach ; the submarginal pink space even through its whole 

 length. Expands 75 to 85'"'". Northern States. C. diaiia has the abdomen partly 

 pink. C. hilUi Grote has yellow hind wings in place of piuk. (Hulst.) 



27. Catocala babai/aga Strecker. 



The caterpillar of this Arizouian species, according to Mr. Doll, 

 feeds on the willow. The moth is like C.junctura, except that the fore- 

 wiugs are of a rich velvety reddish brown. The wings expand 100'"'".
