8 AUG. R. GROTE. 



22. Catocala ilia, Cramer sp. 



^ J . — Primaries dark cinereous, powdered with glaucous scales and shaded 

 with black. A basal ray. T. a. line geminate. Reniform whitish with a 

 small black internal ring. Subreniform pale, subquadrate, connected usually 

 With the t. p. line. Beyond the spots the median space is shaded with black. 

 Sometimes the whole wing is shaded with blackish to t. p. line, leaving the re- 

 niform as a large white blotch without the annulus. Again the wing wants 

 the glaucous scales and the reniform is concolorous, or merely shows a few 

 white scales. Secondaries orange red with an irregular black median band 

 tapering to the margin. Basal hairs fuscous. Average expanse 75 mm. 



An exceedingly common and very variable species, found in Mary- 

 land and Virginia. 



23. Catocala uxor, Guenee. — 



This species has not been recognised by me. I am disposed to re- 

 gard some of the varieties of C. ilia as intended. The use of the spe- 

 cific name is objectionable. 



24. Catocala inmibcns, Guenee. 



% 9 • — A species of moderate size with rich brown primaries, powdered with 

 glaucous scales. The lines are distinct, black and not very jagged. The sub- 

 reniform is small, and pale and a ready character. The wings tend to be dif- 

 fusely shaded with deep brownish from the base outwardly. Secondaries red- 

 dish-orange, with a broad tolerably even median band which tapers suddenly 

 towards internal margin where it becomes lost in the long dull colored hairs 

 which clothe the base and internal edge of the wing. Expanse 65 mm. 



Not uncommon in the Middle and Western States. 



This species must not be confounded with C. muliercula, Guenee, 

 which I refer to the following section from the color of its hind wings, 

 and which wants the whitish serrulate shading before the subterminal 

 line characteristic of C. innubens. I now consider as a well marked 

 variety merely of C. innubens : 

 a. Catocala scintillans, G. &■ R. 



Both sexes of this form have occured rarely. The primaries above 

 are intensely and entirely blackish brown to the transverse posterior 

 line, and this portion of the wing is overlaid by bronze or glaucous me- 

 tallic scales arranged in fine wrinkled lines which in certain lights are 

 brilliant. I was first led to associate C. scintillans with C. innubens, 

 by seeing an analogous variation in C. ilia, and on detecting the glau- 

 cous scales of C. innubens to be brilliant in certain lights, Certainly 

 the two look very distinct, but there seem no other palpable differences, 

 while the paler apices and terminal space and whitish subterminal line 

 of C. innubens are well expressed in C. scintillans. Besides, a speci- 

 men of C. scintillans, in Mr. Edwards' Collection, shows the t. a. line 

 and the subreniform spot of C. innubens plainly.
