(18) WINTHEMIA CECROPIAE, new Bpecles 



Exorista leucaniae var. cecropiae Riley, Fourth Missouri Rep., p. 108, 1872; 



Gen. Index Missouri Reports, p, 60, 1881. 

 Winthemia quadripustulata (part) Coqxjillett, Revis. Tachiu,, p. 125, 1897. — 



Aldeich, Catalogue, p. 474, 1905. 



Riley never published a description of his proposed variety, but 

 one male specimen of the original type series is still preserved in 

 the United States National Museum, E. leucaniae is not recognizable 

 from the description, and with no type specimen extant, so far as 

 known, the name is dropped. Riley's name is here used, according to 

 type, for a large or robust form that may be readily recognized by 

 the abbreviated claws and pulvilli and the uncommonly broad front 

 in the male sex. I am unable to associate the corresponding female 

 in the material examined.
