This species is named after my mother in recognition of her en- 

 couragement of my boyhood entomological interests.

The pattern of maculation of the dorsal surface of the forewing of 

 this species is Uke that of splendens except the gray brown obhque 

 subterminal bar is widest toward the base. The pattern of macula- 

 tion of the dorsal surface of the hindwing is more like that of E. 

 paraguayensis (Draudt). The males have the hindwing mostly white 

 with a narrow marginal band of yellow and a dark brown apical spot. 

 The hindwing of the female is yellowish orange usually with a heavy 

 dark brown marginal band, the latter being widest at costa, bent basad 

 at Mg, usually broken at Cu2 and followed by a short recurved spur of 

 brown scales. The ventral surfaces of the wings of the male are like 

 those of splendens except the hindwing is mostly white. The markings 

 of the ventral siu-face of the forewing of the female are very dark and 

 usually fused together into a large median and subterminal spot con- 

 nected to the dark costal marks. The amount of dark scaling present 

 on both surfaces of the hindwing of females is variable, but more so 

 on the ventral surface, varying from two moderate spots, one at apex 

 and one on costa, to a repetition of the broad marginal band usually 

 occurring on the dorsal surface. Length of forewing: male, 14 mm.; 

 female, 14 to 15 mm. 



Male and female genitalia as illustrated (figs. 29 and 30), inter- 

 mediate to those of the other two segregates of the splendens complex. 

 Left clasper of male genitalia decidedly smaller than clasper of right 

 valve as in splendens and lelae, but costal margin of sacculus of right 

 valve with a well-developed spine as in robertae and paraguayensis. 

 Sclerotized groove in ductus bursae of female genitaha short, extend- 

 ing along ventral siu-face, not directed to either the left or right side. 



Type: A female from Huayabamba, Peru, in the collection of the 

 Konigliche Zoologische Museiun, Berlin, Germany. 



Distribution: Ten examples of this species from the following 

 localities have been exammed. Brazil: Vigosa, Minas Geraes, and 

 Chapada near Cuyaba, Matto Grosso. Argentina: Remsers, Missiones 

 and "Misiones." Paraguay: Puerto Bertoni. Bolivia: Prov. del 

 Sara. There are two females of this species from Salto Grande, 

 Parana and Campinas, Sao Paulo, Brazil in the British Museum 

 (Natural History). This species appears to be intermediate in dis-
