So far represented by the type in the Cornell Collection, a female 

 paratype from St. Petersburg, Fla., in the Barnes Collection, a male 

 from Biloxi, Miss. (June 13, 1917), also in the Cornell Collection, 

 and a male and female from the Fernald Collection in the National 

 Museum (these last are part of the same reared series as the type. 

 They have been partially eaten by a Dermestid but wings and abdo- 

 mens are intact). In all specimens veins 3 and 4 of hind wing are 

 stalked, a very exceptional character in this subfamily and here 

 apparently a specific rather than an individual aberration. 



Female genitalia figured from type. Male genitalia similar to 

 that of transferrawus (fig. 39), but Avith slightly heavier spine-tuft.
