458 Notes on the Lejndoptera of America. 



nently projected at external marginal extremity of second median 

 nervule. Three, narrow, faint, sub-parallel, transverse lines cross 

 the wing, of which the outer, crossing the nervules, is the least 

 distinctly defined. The middle line runs slightly obliquely from 

 costa to internal margin, just beyond the discal cell, crossing the 

 median nervure at about the point at wbich the second and third 

 m. nervules are thrown off together. Posterior wings, resem- 

 bling anterior, crossed by a distinct median line, the latter corre- 

 sponding to the middle line of the primaries. An outer line, pro- 

 minently angulated at the middle of the wing, arising on costa at 

 a point about midway between the apex and the inception of the 

 middle line, and joining internal margin at about the same point 

 with the latter. Fringes, on both pair of wings, pale ochreous, a 

 little darker than the wings. The external margin of the seconda- 

 ries is prominently medially projected. 



Under surface, a little paler than upper surface ; the irrorations 

 are obsolete; the two outer lines of the upper surface are here 

 reproduced.

The palest species of the genus known to us. In the shape 

 of the wings it is allied to E. fiscellaria, Guenee. The wings 

 are slightly silky, but not so diaphanous as in the other species 

 of the genus. The greater number of transverse lines on the 

 primaries and their nearly straight and sub-parallel course, will 

 distinguish this species from its congeners ; the peculiar angu- 

 lation of the outer line on the secondaries, following the out- 

 line of the external margin, though considerably removed, is 

 suggestive of the ornamentation of certain species of Endro- 

 pia. In describing these species of Ellopia, the nervule emit- 

 ted from the discal cross vein, is regarded as the first median 

 nervule. The angulation of the external margin takes place 

 at the extremity of what might be considered the median ner- 

 vure itself, but which is here assumed as the second median
