and rugosely punctate, sonietimes obscured by short silky derm; 

 prosternum carinate and finely granulose, abdomen and femora 

 closely and finely punctate, tibiaj scabrous, and, with the tarsi, 

 clothed beneath with red tomentum. Dimensions 13 x 11-5 mm. 



Bab. — North west Australia. 



A single specimen, male, in the Macleay Museum, is readily 

 distinguished from the other described species with bicostate 

 elytra by its small size and nearly circular form. 



Sar.\gus montanus, n.sp. 



Moderately elongate-ovale, broad, convex, glabrous, black:,nitid. 



Head deeply sunk into prothorax, closely rugose-punctate; 

 epistoma limited at sides by well marked suture, at base by 

 shallow groove, apex truncate, sides widely rounded, canthus 

 raised and separately curved, eyes widely separated, antennse 

 with third joint shorter than two following combined, apical 

 four joints wider and rounder than preceding, elevent!) largest 

 and flattened. Prothorax (4x11 mm.), length measured at middle, 

 width at base; deeply emarginate in front, sides rounded and 

 converging from base to apex, base trisinuate; posterior angles 

 very acute and deflexed; foliate margins wide and concave, 

 extreme margin thin and slightly reflexed, surface of foliate 

 margins finely rugose, transversely wrinkled at border; disc 

 irregularly and distinctly punctate, central channel only indicated 

 by laevigate line, with two smooth impressions, one at each side 

 near front, two transverse foveate depressions at base near 

 scutellum, basal edge finely serrated near sides. SmUellum 

 curvilinear-triangular, punctured as prothorax. Elytra thrice 

 as long as prothorax, of same width at base, gradually widening 

 to middle, broadly rounded at apex; humeri obtuse but distinct, 

 bicostate, with two parallel carinse extending from base, abruptly 

 ending Vjefore apical declivity, about 3 mm. apart and having 

 rows of large punctures on each side; the suture also raised from 

 the middle to apex; between the suture and each carina are two 

 rows of large punctures with additional and more confused 

 puncturation near scutellum, between each carina and the foliate
