236 STUDIES IN AUSTRALIAN ENTOMOLOGY, 



This species resembles A. australis, but is larger, has the pro- 

 thorax more convex and less sharply narrowed behind, the elytra 

 broader and more convex. I should have regarded this species 

 as probably A. concolor, had not M. Putzeys' comparison between 

 that species and A. howitti led me to suppose (though he does not 

 actually say so) that the anterior angles of the prothorax project 

 in A. concolor, as in A. liorvitti; also, from his not noticing it, I 

 think the prothorax in A. concolor must, like that of A. howitti, 

 be without an entire margin on the base. Nor have I been able 

 to regard it as ^. carbonaria, a species I have not seen, because 

 the palpi in the 9 ^^re not broad, the labrum is not rounded in 

 front, and the elytra are very broadly rounded behind. 



AdOTELA AUSTRALIS, n.Sp. 



9. — Black, shining. Head convex behind, rather rugose in the 

 frontal impressions, these broad and shallow ; pre-ocular promi- 

 nences small ; eyes prominent, not inclosed behind, the .sides of 

 the head not swollen behind them. Antennae moniliform, apical 

 joint short with the apex rounded. Labrum very slightly emar- 

 ginate ; the median impression light, only visible near the clypeus. 

 Prothorax transverse (4 x 4^ mm.), convex, declivous behind, 

 truncate in front and behind, broadest a little before the middle, 

 broad in front ; the anterior angles very .shortly rounded, 

 not advanced ; sides lightly rounded, decidedly narrower to the 

 base ; the marginal border narrow, a little sinuate before the 

 base, entire on the base ; the basal angles right angles ; the 

 median line lightly marked, crossed behind by a lightly marked 

 transverse impression. Elytra oval (8x5 mm.), convex, smooth, 

 rounded at the shoulders and declivous to the peduncle, apex 

 broadly rounded, sides parallel ; lateral margins fine, wider behind ; 

 the marginal punctures as in A. atronitens, only the elytra not 

 undulate near the sides towards the apex ; a faint puncture on 

 each elytron near the base ; the suture very lightly impressed. 

 Ventral segments (except the apical) Avith two punctures towards 

 the middle and no lateral fovefe ; the last segment with two punc- 

 tures on each side of the anus. Anterior legs with the thighs
