NO. 3546 MOTHS OF GENUS EUSCEPTIS TODD 13 



Distribution : Known only from the type locality. 



Remarks: This species agrees with irretita and differs from the 

 similarly marked species in that the outer, dark costal mark of the 

 forewing is about equal in width to the median costal mark. The 

 species is slightly larger than irretita, has the outer, dark costal 

 mark of the forewing distinctly looped immediately above lower 

 angle of the cell, and has the terminal orange line extending around 

 the apex of the wing. In addition, the male genitalia are specifically 

 distinct.

The splendens complex is composed of at least five species, some 

 of which have been misidentified as splendens or treated as forms or 

 aberrations of that species. The species of this complex (figs. 9-18) 

 may be separated from the other species of the genus by the following 

 combination of maculational characters: hindwing with some orange, 

 yellow, or white, terminal area of forewing with some yellow between 

 vein Ml and tornus, and outer, dark costal mark of forewing about 

 twice as wide a median costal mark. 



The species of the splendens complex form three segregates on 

 genitalic and maculational characters. E. splendens (Druce) and 

 E. lelae, new species, extremely closely related species, form one segre- 

 gate. Two other species, E. paraguayensis (Draudt) and E. robertae, 

 new species, belong to a second distinct segregate. The fifth species, 

 E. extensa (Strand), is intermediate on maculation and genitalic 

 characters and is considered to be a separate segregate. The species 

 and the segregates of the splendens complex can be identified by 

 means of the characters utilized in the keys. 



The known geographic distribution of the four species of the 

 splendens complex in South America is illustrated on map 1. The 

 fifth species, E. lelae, new species, is known to occiu" in Mexico, 

 Guatemala, and Costa Rica. 



E. splendens (Druce) is red escribed in this paper because other 

 species of the complex have been confused with it in the past and
