Australian and Tasmanian Coleoptera. 179 



rather darker and less punctate alonji;- middle than on sides, 

 third to tenth joints each about eight times as wide as long, 

 apical joint slightly longer than three preceding combined. 

 Prothorax scarcely two-thirds as long as greatest width, sides 

 strongly rounded on apical half and decidedly oblique on basal 

 half, sides feebly raised and thickened, median line very 

 feeble ; with fairly numerous but small punctures about apex 

 and apical sides, but elsewhere almost or quite impunctate. 

 Elytra wide, not three times as long as prothorax, with 

 numerous small punctures, becoming extremely minute pos- 

 teriorly. Hind tibiae about once and one-half as long as their 

 greatest width. Length 10, width 4 mm. 

 //«&.— N.S. Wales: Sydney (A. J. Coates). 

 Comparatively wider than any other described species of 

 the genus. The prothorax is considerably wider than in brevis, 

 apical joint of antennae longer, and the whole insect bulkier ; 

 in brevis the extreme width of the prothorax appears to be 

 scarcely, if at all, greater than the extreme length, in the pre- 

 sent species it is about once and one^half its length. The 

 third to tenth joints combined are rather more than once and 

 one-half as long as wide. The disc of the prothorax appears 

 to be extremely feebly corrugated (as in many Carabidae), and 

 is almost impunctate. 



There are several other species before me that are possibly 

 undescribed, but as Macleay usually omitted to describe the 

 comparative width of the hind tibiae I do not feel justified in 

 describing them till able to examine his types.
