Garde, Shapiro, Clench — Lethe 
85 
Taxonomic History. — described from 17 males and 8 females, all 
labeled “Omaha” by Leussler, as are various later topotypes. Al- 
though it was described as a “variety,” the geographic nature of 
fumosa was clearly expressed. 
The Greek noun Ar|#r| is feminine and retains its gender in the 
Latinized form Lethe. Both the species names in this group are 
also feminine. We have adopted the spelling fumosa to make this 
subspecies agree in gender, as provided by the Code. 
Summary of Characters. — Lethe eurydice fumosa resembles L.e. 
eurydice in most respects, but the males and some females are 
darker above. The four eyespots on the forewing are consistently 
graded in size, from the smallest on top to the largest at the bottom ; 
this is especially obvious beneath. The male valves have far fewer 
setae than in L. e. eurydice. The early stages are unknown.
