Hah. —Cuba. One specimen. Coll. Ent. Soc. Phila. 
A very beautiful and distinct species. The Society is indebted to 
Mr. P. R. Uhler, for the 9 specimen from which the above description 
is taken. The S is unknown to me. Gruerin says, “ We possess a 
female which in truth belongs to this species, but we have received it 
from Mexico. The superior anal plate terminates in a point and is 
carinated above; the inferior plate is longer, nearly straight, and a 
little hollowed out on each side towards the extremity.” The shape of 
the anal plates given here does not accord with that of the 9 specimen 
from which I drew up the description given above, and therefore either 
Gruerin’s 9 from Mexico, or mine from Cuba belongs to another species.
