 tains, Califorr, . April, 1891 (A. Koebele, through C. V.

Elophila fulicalis Clemens. 



Cataclysta fulicalis Clemens, Proc. Acad. Nat. Sci. Phil., xii, 



217, 1860. 

 Cataclysta angulatalis L,ederer, Wien. ent. Mon., vii, 453, 486,

This species can be distinguished from opulentalis Led. by 

 the presence of a small black discal dot on fore wing and the 

 absence of a distinct narrow dark line on hind wing. Opulen- 

 talis has a discal ringlet, not a dot. 



The following may be races of fulicalis, but for the present, 

 I give them specific rank. 



Elophila satanalis, new species. 



Fore wing with the base brown; subbasal line white, dif- 

 fused ; a broad brown band, stained with orange in the middle, 

 followed by a straight white line with dark outer edge ; middle 

 field brown above, irrorate with black below ; a blackish discal 

 spot in a brown cloud ; an orange line from discal dot to tornus ; 

 oblique subapical and subterminal white lines separated by an 

 orange spot ; terminal band orange. Hind wing with the broad 

 band containing an orange spot, its outer edge angled and 

 followed by a more or less distinct line ; black irrorations all 

 the way across the median space ; terminal dots not preceded 

 by a line. Expanse, 18 mm.
