Museum,’ iv. p. 88, and Tijdschr. voor Ent. xxvi. p. 36), the palpi, the basal joints 
of the antenne, and the anus, also are rufous; but this must be a different species, as, 
according to Macquart, it has the hind tibie clothed with long hairs (trés velues) in 
the male. The specimen from Curagao is larger than the Mexican insect, and differs 
from it in the shape of the interior orbits of the eyes and in having the hind tibie not 
fringed with short hairs.
