Neiv 8pecies of Heteromera. 271 



Alcmconis pulehra, n. sp. (PL XII. fig. 4) . 



9 . Length 5 lines. Head and thorax castaneous ; 

 elytra green, with purple reflections : shining, clothed with 

 a silky golden pubescence. Head coarsely punctured. 

 Thorax depressed, longer than broad, moderately punc- 

 tured, the sides subparallel or very gradually widening 

 to the base, which is subsinuous, faintly impressed down 

 the median line; a large round shallow impression at 

 the middle of the base, within the margin, and another, 

 oblique, on each side, completely marginal; an angulate 

 patch at the base, and a line down the centre, black. 

 Scutellum black. Elytra depressed along the suture and 

 on the discs, truncate at the base, which is rather 

 more than half as wide again as the prothorax ; broadest 

 behind the middle, thence contracted to the apex; 

 crenate-striate, the interstices moderately convex, spar- 

 ingly punctured , and transversely wrinkled. Body be- 

 neath, deep shining black, pubescent ; legs, palpi, and 

 three first joints of the antennae clear red, remaining 

 joints of the latter black. 



Hab. — South Australia (Adelaide) . 



LiCYMNIUS, n. g. 



Also veiy closely allied to Atractus. It differs from 

 that genus in the following particulars : — Last joint of the 

 labial palpi more briefly and broadly triangular ; the 

 second of the maxillary longer and more slender, the last 

 shorter and more broadly cultriform; the foliaceous ap- 

 pendage at the inner side of the base of the mandibles 

 smaller, shorter, less regularly falciform ; antenna * sub- 

 compressed : joint 1, less swollen; 3, relatively shorter ; 

 10, longer and narrower, the last luuch shorter, scarcely half 

 the length of the 10th, subovoicl; head broader, less pro- 

 duced in front; thorax wider, squarer, depressed, the base 

 subsinuous ; scutellum angulate behind ; elytra flatter, 

 gradually tapering from the shoulders to the apex, the 

 epipleurae continued nearer to the extremity ; legs— 

 especially the posterior pair — much shorter, less robust; 



* Starting from the apical half of the third joint, the whole sm-face of 

 the antennas, iinder the microscope, appears rugged with approximate 

 punctiu-es and rugosities, a feature which is not repeated in any of the 

 allied genera.
