Hab. — New South Wales : Mount Kosciusko (B. Ingleby, 

 — Lucas, and — Guerand, 7,000 ft., in Howitt's collection). 

 Type, I. 589. 



A strongly-convex dull species, but with shining elytra. 

 Specimens vary somewhat in the punctures of the elytra and 

 one has a few fairly well-defined striae, but all agree in having 

 the prothorax with very dense punctures, with a minute 

 seta arising from each ; on many of them the setae have caused 

 mud to adhere uniformly to the surface, giving it a curious 

 appearance ; the setae on the upper-surface of the head are 

 just as dense, but from several specimens have been completely 

 abraded ; the elytra have a few extremely minute setae 

 towards the sides, but from most directions they are invisible. 

 The apex of the scutellum is without punctures, the apparent 

 base has a few large ones, and the real base (normally con- 

 cealed by the overlapping base of the prothorax) has dense 

 ones. I have been unable to find external indications of sex 

 in the eleven specimens under examination. The eight- 

 jointed antennae and general appearance associate the species 

 with baldiensis and creber, from which it may be readily 

 distinguished by the prothoracic clothing. 



PSEUDOHETERONYX BASICOLLIS, n. Sp. 



PI. xxv., figs. 32 and 33; pi. xxvi., fig. 62. 



Black; parts of antennae, of palpi, and of tarsi obscurely 

 reddish. Upper-surface sparsely clothed with short, depressed 

 setae, more numerous (but still not very dense) on head than 

 elsewhere ; prothorax and elytra fringed with stiff blackish 

 setae, similar setae on parts of under-surface and of legs. 



Head with numerous, but not very dense or large, and 

 rather shallow punctures, becoming crowded on clypeus ; 

 front margin of the latter gently incurved to middle, hind 

 suture lightly impressed and sinuous. Antennae nine-, club 

 three-jointed. Prothorax scarcely twice as wide as long, sides 

 strongly and evenly rounded, base evenly incurved to middle, 

 front angles produced and subacute, hind ones rounded off, 

 median line absent ; punctures similar to those on head but 

 sparser, a few very small ones scattered about. Scutellum 

 with numerous punctures. Elytra with sides gently rounded 

 and apex almost truncate ; punctures slightly larger than on 

 prothorax. Pygidium and metasterniim with rather coarse 

 punctures. Front tibiae strongly tridentate ; two basal joints 

 of hind tarsi subequal; claws strongly appendiculate.
