LEXIPHANES NORTH OF MEXICO — BALSBAUGH 667 



neither describes nor "characterizes" its names. In it, L. ater is Hsted 

 as a synonym of "Indicus Knoch" in the genus Cry otocephalus. 



Male genitaHa: Apparently the only published illustrations of this 

 structm-e appear in Powell (1941). The length of the adeagus is 

 0.70 mm. long; its wddth is 0.28 mm. It is larger than that of the 

 other species and gives the impression of relative compactness. The 

 portion of the ventral apical lobe beyond the dorsal plate is less than 

 half the mdth of the aedeagus at the median orifice. Twenty speci- 

 mens were dissected.

Female genitalia: No published illustrations of the spermatheca 

 were found. This structure is much larger than that of any other 

 Nearctic species. Twenty-one specimens were dissected.
