From the dates of capture it would appear that there are 

 tw^o broods of this species. "In Montgomery County, Vir- 

 ginia, cellus is occasionally taken in the watered rocky ravines 

 where the wild catnip covers the ground " (Smyth). 



Eudainus (Rliabdoides) pseudocellus. 



Achalarus pseudocellus Coolidge and Clemence, Ent. News, 23, 3, 1911, 

 ''Male. — Upper surface of primaries brownish-black, somewhat 

 lighter along the external margin, and sparsely dusted with whitish 

 atoms, a macular band extending from costa across end of cell and 

 abruptly terminating about 2.5 mm. from lower angle ; this band is 

 divided by the nervules into five spots as follows : first, quadrate ; 

 second, elongate; third, with the nervules Y-shaped and projecting 

 outwardly; fourth, quadrate; and the fifth, triangular; the formation 

 of this band is similar to that of cellus, and is quite regular, the fifth 

 spot, however, varying considerably in size and shape ; color of first 

 spot pure yellow ; the second orange, slightly tinted with yellow ante- 

 riorly ; the others all orange ; midway between this band and the apex 

 a small procurved whitish-yellow bar ; otherwise immaculate. Second- 

 aries concolorous with primaries, immaculate, fringes of primaries- at 

 lower angle whitish, becoming black checkered as they approach the 

 apex, where there is usually a distinct whitish patch of fringes. 

 Fringes of secondaries checkered black and gray. Primaries beneath 

 with spots reproduced ; color as above but considerably lighter along 

 outer margin and dusted sparsely with grayish scales ; inner angle 

 clouded with buflf, in some specimens a distinct whitish point below
