15 AUG. R. GROTE. 



lightly, from t. a. line outwardly. T. p. line perpendicular with a hroadly 

 marked sinus, with one hardly prominent tooth. Two specimens in Mr. Ed- 

 wards' Collection have the wings somewhat hoary and the lines more perceiva- 

 ble. These are labelled aimilis. This species has the primaries of a purer grey 

 than usual. It approaches C. androphila in the appearance of the wings; the 

 secondaries are deep>yeHow, with a narrow even median band discontinued much 

 before the margin. Hind border discontinued and appearing again as a detached 

 large spot near the angle. Beneath the band is attenuate. Thoracic lines dis- 

 tinct. Veins of the primaries above indicated. Expanse 40 to 42 mm. 



New York, Rhode Island; not uncommon. 



52. Catocala androphila, Guenee. 

 Corisce arnica, Hiibner. 



% 9- — Primaries pale gray, the lines fine, not very evident, the t. a. line the 

 heavier marked. A distinct black median shade on costa above the reni- 

 form and continued beneath it, running upward to external margin below 

 apex. A brown shade fills the space left by the exserted portion of the t. p. 

 line beyond the reniform. This black median shade is marked on costa, but 

 else sub-obsolete in all the males I have before me and the brown shading very 

 faint. The t. p. line minutely dentate without prominent teeth. Subreniform 

 small, pale and both spots inconspicuous and often incompletely ringed. The 

 serrated sub-terminal white shade is tolerably distinct; fringes dark. Hind 

 wings bright yellow ; abroad black terminal band is squarely discontinued 

 and appears as a black dot at anal angle. Fringes dark except at apex, where 

 is a small yellow patch. Beneath the marginal band is brokenly and narrowly 

 continued to anal angle and the median band is indicated by tolerably large 

 spots or fragments. A specimen from Texas differs by its dirty, ochreous grey 

 primaries much shaded with deep black and may be a distinct species. Ex- 

 panse 40 to 45 mm. 



Eastern States, southward. Not rare. 



According to Guenee, who describes from Abbot's unpublished draw- 

 ings, the larva feeds on oak. The specimen in the British Museum 

 determined as " Catocala arnica" is an Ephesia elonympha, Hiibner. 



53. Catocala lineella, Grote. 



% 9 • — A little smaller than C. androphila. The primaries notably darker, 

 being powdered with glaucous, bluish or greenish-grey, and black scales on a 

 paler ground. Lines black and more distinct while similar to C. androphila; 

 subreniform connected more or less evidently with the t. p. line. Serrated 

 whitish subterminal shade and marginal black lunated line distinct. Second- 

 aries deep yellow, a few dusky hairs at base. Terminal band much as in C. 

 androphila. Beneath, the median band is merely expressed by two small dis- 

 connected dots, of which the upper is sometimes wanting and occasionally both. 

 Expanse 36 to 38 mm. 



Same localities as C. androphila. 



Perhaps this is Guenee's var. a of C. androphila. I have a number 

 of coincident specimens and I believe it to be distinct speci6cally.
