males of those species with appencliculate claws, the basal portion 
of the anterior claws is usually stouter than in the females, and 
the hind-body of the females throughout the genus is longi- 
tudinally (i.e., as viewed from the side) considerably more convex 
than that of the males. 
The present memoir contains descriptions of all the previously 
undescribed Australian species known to me, of the first main 
group (or “section”), of the 2nd (or “intermediate section”), and 
of that portion of the 3rd in which the antennte are 8-jointed and 
the claws bifid. I prefix tabulations to aid the study of the des- 
criptions that follow, and have included in them the names of all 
the previously described species of which I have types before me. 
The following species I have not been able to identify, nor are 
their descriptions sufficiently detailed to allow of my placing them 
in the tabulation without actual inspection of specimens. They 
all belong to the group treated of in this present memoir ; — 
H. latice])s, Bunn. Exact habitat not known ; probably it is 
allied to H. corpulentus, Mach, but distinguished by its pale colour 
and by the truncate apex of the elytra, — the outer extremity of 
truncation being sharply angled. 
H. planalus, Biirm., from S. Australia. It is said to be remark- 
able (as its name implies) for its flattened form. 
II. proicox, Er., from Tasmania. Probably near my H. c&qualis 
but distinguished inter alia by the prothorax being feebly 
channelled. 
H. temj)estivi(,s, Er., from Tasmania. Probably near my H. 
teslaceus, but with the clypeus evenly rounded in front. 
H. pilosellus, Blanch., from N.S.W. Not sufficiently charac- 
terized, no definite distinction from H. piceun, Blanch., being 
pointed out. 
II. piceo-niger. Mad., from N.W. Australia would j)roVjaV)ly 
come war corjyalentus in my taVjulation.
