NEW AUSTRALIAN JiEES. 57 



coutiguous, punctures ; hair in middle line and around antennae 

 very beautifully plumose ; hair at ujjper part of sides simple. 



(2.) Mesothorax. 



H. warhurtoni. ~ With shallow but large and almost con- 

 tiguous punctures all over ; they are somewhat shiny, and the 

 intervals are smooth. (The scutellum is also extremely densely 

 and strongly punctured.) 



TL mitcJidli. — Strongly and closely, but not contiguously, 

 punctate on a smooth ground ; a few minute punctures inter- 

 spersed. The interval between the punctures perhaps averages 

 from half to three-quarters the width of a puncture, though in 

 places it is more. (Scutellum has very small punctures, with a 

 few larger ones interspersed ; the punctures are mostly scattered, 

 not dense.) 



H. burkei. — Eather shining, minutely but very distinctly 

 tessellate, with very distinct but very widely separated punc- 

 tures. 



H. tvillsi. — Eough, and contiguously punctured all over. 



H. sturti. — With widely separated weak punctures, on a 

 rather obscurely tessellate surface. 



H. leichardti. — Obscurely tessellate, with rather close strong 

 punctures all over, except that anteriorly the punctures become 

 weaker and sparser. 



H. forresti. — Minutely tessellate, with rather shallow fairly 

 close punctures. 



(3.) Second abdominal segment. 



H. ivarhartoni. — Basal half well-punctured, on a micro- 

 scopically tessellate surface ; aj)ically the punctures get smaller 

 and much more distant, and the tessellation gives way to a 

 transverse lineolation. 



H. mitchelli. — With small regular punctures all over, averaging 

 about as far apart as twice the diameter of one. Ground ob- 

 scurely transversely lineolate. Hind edge of segment (as also of 

 first) very narrowly light yellow (so narrowly that it is not readily 

 noticed with a lens). 



H. hurkei. — Dullish, not punctate ; the basal part minutely 

 transversely lineolate. 



H. icillsi. — Minutely and densely, though not contiguously, 

 punctured. The broad depressed apical part transversely lineo- 

 late, with minute widely-separated punctures. 



H. sturti. — Obscurely lineolate, with only minute scattered 

 hair-punctures. The subapical region has a row of depressed 

 dark bristles. 



H. leichardti. — Closely punctate, the punctures small but 

 strong. 



//. forresti. — Dullish, with very minute and quite sparse
