30 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.64 



From a cotype specimen from St. Vincent in the collection of 

 Cornell University. Johnson has recorded the occurrence of the 

 species in Florida (Florida List). The National Museum has a 

 specimen from Chinandega, Nicaragua, collected by C. F. Baker. 

 After an examination of a cotype specimen Malloch located the 

 species in Clusiodes, but Williston stated in his Manual that the 

 cruciate bristles are lacking, as they are also in the present specimen.
