much wider than long; sutural striae distinct, the others feeble. 

 Under surface of abdomen with a rather deep, suboval, median 

 fovea. Motasternum with a wide, polished, median excavation, 

 continuous throughout but narrowed to base. Length 2^-2 1 mm. 



Q. Differs in the metasternum being flattened along middle, 

 and the abdomen without a fovea. 



Hab. — Tasmania : Mount Wellington, Hobart, Waratah(A, 

 M. Lea). 



From some directions each side of base of prothorax appears to 

 be supplied with two deep grooves, with a narrow carina between 

 them. The species is longer and narrower, with the basal joint 

 of antennse longer than usual, and the sexual characters very 

 pronounced. Of the twelve specimens before nie, six were taken 

 from moss, and six from fallen leaves. 



PSELAPHUS TUBERCULIVENTRIS, n Sp. 



(J. Bright reddish-castaneous, palpi and tarsi somewhat paler* 

 Sparsely clothed with pale, subdepressed pubescence; elytra 

 fringed at apex, and with feeble lines of pubescence on disc. 

 Under surface with dense white pubescence at base of abdomen, 

 on mesosternum, apex of prosteinum and middle of neck. 



Head moderately long, with a distinct median channel from 

 base to apex, but irregular between eyes. AntenuBe moderately 

 long, first joint as long as the three following combined, second to 

 eighth but little, or not at all, longer than wide, ninth and tenth 

 longer than wide, and combined about equal to eleventh. Palpi 

 elongate, club of apical joint about half the length of peduncle, 

 this distinctly curved. Prothorax very distinctly longer than 

 wide, with five subbasal impressions. Elytra much shorter than 

 abdomen, about as long as wide; sutural stria distinct, discal 

 fairly distinct. Undersurface of abdomen strongly convex in 

 middle, and at its highest part with a strongly raised truncated 

 tubercle. Length 2^ mm. 



^. Diflfers in having shorter antennae and abdomen non-tuber- 

 culate.
