A pretty species, with somewhat brilliant iridescence. I 

 have a specimen from the same locality as the type which I 

 believe to be its female ; it is very much damaged and crush- 

 ed, and differs from the male in the somewhat shorter flabellum 

 of its antennae, its pygidium gibbous near the base, and its 

 punctaration in general somewhat closer and stronger. The 

 most noticeable specific characters of this species seem to be 

 its clypeus more elongate, and in front more narrowly rounded 

 than in allied species, and the extremely strong, rounded dila- 

 tation of the sides of its prothorax behind the middle. It is 

 rather close to H. decepfor, Blackb. (from Central and South 

 Australia), but differs from that insect by, infe?' alia, its longer 

 and anteriorly narrower clypeus, its prothorax less convex 

 (transversely), and with sides much more strongly rotundate- 

 ampliate, and the different proportions of its tarsal joints.

Easily distinguishable from all its near allies by the sides 

 of its prothorax not being rotundate-ampliate. This segment 

 is very little convex (i.e., not in any marked degree declivous 

 hindward near the base). In colouring resembles Tf . heJIa, 

 Blackb. I have not seen a female example.
