PSILEPHYDRA Hendel.! 
A species was recognized from Costa Rica as belonging to a 
new genus, and I had drawn up a description of it as such 
when the Supplementa Entomologica came to hand. Hendel’s 
new genus, erected for a species found in Formosa, was at 
once recognized as being similar to, if not identical with, my 
new one. The drawing had been made and engraved, or I 
would have given figures of characters of more specific im- 
portance. In addition to the form of the head, there are 
other essential characters which make it very probable that 
the Costa Rican species belongs to this genus. It is extremely 
interesting that species from so widely separated localities 
should be discovered about the same time belonging to the 
same and a new genus. The following notes are based on the 
examination of the Costa Rican specimens only. 
This genus may be distinguished by the peculiar shield-like 
development of the face which extends rather low, appearing 
somewhat subhemispherical, being evenly and distinctly con- 
vex in all directions, including the cheeks. There are no in- 
dications of the usual parafacial grooves or areas, and the 
face is destitute of characteristic bristles or hairs. In general 
the face appears vaulted or arched, as is typical with Ephydra 
and Parydra, but the mouth is not proportionately so large.
