elongate, pale yellow, with narrow sutural, median, and submarginal 

 vittae not united at the apex; surface faintly shining, finely alutaceous 

 and finely punctate. Epipleura with dark edge. Body beneath and 

 femora entirely pale yellow, tibiae and tarsi reddish brown, the first 

 tarsal joint in the anterior pairs of legs much enlarged in the male. 

 Length 5.6 to 6.2 mm., width 2.3 to 2.5 mm. 



Type: Male, USNM 61814 (from the Biologia Centrali-Americana 

 material), Jalapa, Mexico, Hoge collector. A male in BM (Fry 

 collection) is labeled Truqui, Mexico. 



Remarks: The striking characteristics of this species, represented 

 by onl}^ two specimens, are its slender, elongate shape and the unusual 

 shape of the aedeagus, with its darkly cliitinized areas. The type 

 specimen, evidently from the Biologia material, has been dissociated 

 from its original arrangement so that I cannot tell under which species 

 Jacoby placed it. There was also a specimen among the unidentified 

 material sent me from the British Museum.
