E'RIDBIOPTEKA OF THE NEW WO'RLD — ROSS

Remarks. — The holotype of this species, mounted on a slide in bal- 

 sam, was in such poor condition that Davis (1939d) was unable to 

 establish with certainty the generic position of the species or ade- 

 quately to redescribe the terminalia. Recently, through the kindness 

 of Dr. Banks, the writer has been able to remount the fragmentary 

 specimen after first treating the parts in KOH. Many essential details 

 of the terminalia are now visible, and it is apparent, by comparing 

 holotypes, that Anisemhia sckwarsi Ross is with little doubt a syno- 

 nym of venosa. The details of the head and terminalia of the holo- 

 type of venosa are shown in the accompanying figures.

The holotypes of venosa and sclvwarzi differ in a number of striking 

 details, which, however, because the specimens are from the same state 

 of Cuba, are regarded as interspecific variation. The shape of the 

 left tergal process (10 LP) is quite different and may not be due to 

 the angle of view (cf. figs. 79 and 81). The lobe of the left cercus
