Prosopis flavifrons, Kirby, Ent. Mo. Mag. XVII. p. 85, 
male. 
Allied (but not very closely I think) to P. Blachburni, 
Sm., and P. facilis, Sm., this insect may be readily 
identified by the following characters :~The yellow 
mark on the face occupies the whole space in front 
of the antennse, but does not extend behind them. 
The clypeus is rounded in front. The basal joint of the 
antennse is extremely compressed, being, on the flat 
face, scarcely longer than wide, and of subcordiform 
shape; the anterior margin of this joint is narrowly 
testaceous. Near its apex the flagellum is testaceous 
beneath, while the legs are of an obscure colour 
except the front tibise, which are testaceous in front. 
The head does not differ much in shape from that of 
P. facilis, Sm., nor is the punctuation of the insect 
much different. The length is about 7| mm. I 
have found this species only on Kauai, and have not 
seen the female.

This is a very distinct species. In the male the face is 
colored as in typical P. Blachburni. The anterior 
margin of the thorax and a spot under the tegulse are 
yellow; the tibise are yellow with a black spot on the 
posterior face of the front pair, and a similar spot on 
each side of the others; the first joint of each tarsus 
is yellow, the remainder are fuscous ; of the antennae, 
the lower surface of the flagellum is testaceous, and 
the basal joint is much compressed (considerably 
more so than in P. Blachburni), but the dilated face
