AMERICAN LEPIDOPTERA. 9 



25. Catocala cerogama, Guenee. 



% 9- — A rather large species with the body parts proportionally slender. 

 Forewings pale wood brown, frosted with white scales and shaded with bright 

 brown and whitish. T. a. line geminate, strongly marked outwardly to sub-me- 

 dian interspace, to below the white and prominent sub-reniform. A broad 

 whitish shade extends downwardlyand outwardly obliquely from costa over the 

 diffuse palebrownish reniform spot, bringingthe strongly marked t. a. line,which 

 it margins inwardly, into relief superiorly. T. p. line black and distinct to 2d 

 nervule, accompanied by bright brownish shades ; the brown bright color ob- 

 tains between the t. p. line and the whitish bordering of the dentate sub-ter- 

 minal line. The veins tend to being marked by dark scales. Hind wings 

 black with an even narrow median yellow band. Base clothed with long 

 pale fuscous hairs, beneath which the yellow scales that clothe the wing may be 

 detected. Thus, in reality, the hind wings do not differ from those of the suc- 

 ceeding group in pattern. Beneath, with primaries, they are pale yellow, crossed 

 by a broad median and marginal black band, the latter retired from the edge 

 of the wing. Expanse 75 to 85 mm. 



Not common. Eastern, Middle and Western States. 



26. Catocala neogama, Guenee. 



% 9 • — A stout bodied species of strong habit. Primaries above cinereous, 

 varying in depth of shade. Basal half line black, distinct, and there is a basal 

 ray, usually evident, accompanied by a brown shade. T. a. line better defined 

 superiorly and outwardly and, with the t. p. line, accompanied usually by 

 bright brown shadings. Reniform tolerably large and distinct, with an 

 interior shaded brown annulus; the disconnected subreniform is pale and 

 moderate though well defined. T. p. line single with two strong subequal 

 teeth and a strongly marked inflection on s. m. interspace. Subterminal in- 

 terspace usually bright brown. S. t. line inconspicuous; the usual sub-apical 

 dark shade or streak. Hind wings dark yellow with an irregular median band , 

 tapering, but continued beneath the longer dark fuscous hair to internal margin, 

 constricted superiorly. Basal hairs dark. Beneath all the black bands very 

 attenuate. Expanse 80 to 82 mm. 



Eastern and Middle States; very common. 



I do not believe this to be tbe Phalaena neogama of Smith. In 

 the Berlin Museum I have named this species Catocala communis, 

 while two specimens from Texas therein contained differed from the 

 present by their brighter colored secondaries, and otherwise more nearly 

 resembled Abbot's figure. I determined these two latter specimens as 

 C. neogama, Smith sp. I have no further material from the South at 

 the moment before me, but believe my determinations in 1867 will be 

 justified by future discoveries. 



27. Catocala subnata, Grote. 



Catocala subnata, Grote, Proc. Ent. Soc. Phil. p. 327 (1864). 



% 9 • — Anterior wings pale grey with a greenish or bluish tinge. All the 

 lines are narrow, better defined superiorly, not very distinct. Reniform 

 smaller, less prominent than in C. neogama, Guenee, which this species closely
