RHOPALOCEKA. 657 



Hab. Mexico, Omilteme and Xucumanatlan in Guerrero, Sierra Madre del Sur 

 7000 to 8000 feet (H. H. Smith 1 ). 



This very distinct species, of which we possess four males, belongs to the section 

 of the genus containing E. argentella and its allies ; it may be readily distinguished by 

 the dentate margin of the secondaries and the prolongation of the anal angle, the 

 blunt apex of the primaries is also a marked feature.

$ mari similis. 



Hab. Noeth America, Southern States 1 . — Mexico (Mus. Berol. 2 ) ; Guatemala, 

 Polochic Valley (F. I). G. & 0. S 2 ), Chiacam (Champion). 



Two species were confused by us under the above name : one, the true E. gemma 

 (Hiibn.), the male of which has the primaries uniformly coloured above ; the other, 

 from which our description and figure were taken, has, in the male a dark patch on 

 the disc of these wings, which are, moreover, distinctly produced at the apex in this sex. 

 The last-mentioned insect is here separated under the name E. pephredo. Of the true 

 E. gemma, Mr. Champion subsequently sent us two males from Chiacam, Vera Paz ; 

 the other Guatemalan localities previously quoted 2 , with the exception of the Polochic 

 Valley, must be transferred to E. jpephredo. A comparison of Edwards's figures 1 with 

 the one given by us 2 will readily show the difference between the two species.

Euptychia gemma, antea, i. p. 92, t. 8. f. 12 (<$) \ 



Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith), Cordova (Mumeli) ; 

 Guatemala, central valleys, Duenas (F. I). G. & 0. S.) y San Geronimo (F. D. G. 

 & 0. S., Champion 1 ). 



We have now seen ten specimens of this insect, which may be readily separated 

 from E. gemma by the characters noted above under that species. It is one of a group 

 the males of which have a patch of darker scales on the disc of the primaries above, 

 no trace of this being visible in E. gemma.
