REVISION OF GENUS EUCERCERIS CRESSON 51 



all coxae and trochanters black marked ^\^ith considerable creamy 

 white, fore femora black with large creamy white patches apically, 

 remaining parts of all legs largely ferruginous with a large creamy 

 white patch on the mid femora and small spots on the fore and mid 

 pau" of tibiae; wings subhj^aline with dark patches near the apex; 

 the 2nd submarginal cell is not petiolate. 



Abdomen black except for a broad semidivided band on tergum 1, 

 emarginate bands on terga 2, 3, 4, 5, and 6, bands on sterna 2 and 3, 

 and lateral patches on sternum 4, all of which are creamy white; 

 wide prominent rows of bristles appear inserted on the apical mar- 

 gins of sterna 3 and 4, a very indistinct pair of bristle clusters may 

 appear on sternum 5; the pygidium has the form illustrated (fig. 82f). 



Both sexes of E. morula morula ScuJlen closely resemble E. vittati- 

 jrons Cresson in size and color. The females may be distinguished 

 by the structure of the clypeal borders and the males by the color 

 pattern of the face, the abdominal bristles and the venation of the 

 ■uings. The male of E. morula morula is close to the male of E. baja 

 Scullen but is distinguished from that species by the ferruginous 

 area back of the eye and a very distinct row of bristles on sternum 5 

 on the latter species. The male of E. pacifica Scullen is also very 

 close, but the key should separate them. (See notes under E. morula 

 albarenae Scullen, p. 48.)
