Head with crowded and small but seldom confluent 

 punctures; with a lightly elevated, semidouble, transverse 

 median ridge ; clypeus with slightly larger and sparser punc- 

 tures than between eyes, sides strongly decreasing to apex, 

 which is truncate, but with angles widely rounded off. 

 Antennae eight-jointed. Prothoraor less transverse than usual, 

 sides moderately rounded, hind angles obtuse but not com- 

 pletely rounded off, front ones produced and acute, median 

 line vague ; punctures small and sparse. Elytra with rather 

 sparse punctures of moderate size: geminate-striae well 

 defined. Hind parts with rather dense and small punctures, 

 the propygidium with an obtuse median tubercle. Front 

 tibiae strongly tridentate ; basal joint of hind tarsi distinctly 

 longer than second. Length, 7 mm. 



Hab. — New South Wales (Blackburn's collection). Type 

 (unique), I. 4580. 



Belongs to Group 17; but the type is a specimen assumed 

 by the late Rev. T. Blackburn to be tuberculatus, and placed 

 by him in Group 19, on account of its antennae appearing to 

 be seven-jointed. As a matter of fact it is neither tubercidatus 

 nor a member of .Group 19, its antennae being really eight- 

 jointed. The left antenna has the joints of the club separated, 

 and the fifth joint is so small and so closely applied to the 

 base of the club that as a joint it appears to be non-existent, 

 and in consequence that antenna appears to be seven- jointed; 

 but on the right antenna the fifth joint is less closely applied 

 to the club, and is seen to be acutely pointed on one side. The 

 basal joint of the hind tarsi is very decidedly longer than the 

 second, although less conspicuously so than on criniger, from 

 which it differs in its opaque pronotum, and very different 

 clothing. In general appearance it is close to many species, 

 but by the use of Blackburn's table it may be readily 

 separated from all others. The clothing of the abdomen 

 consists of a row across each segment : at the side rather long 

 pale depressed hairs, across the middle short stiff suberect 

 setae ; the elytra have fragments of a very short apical 

 membrane. 



Group 19. 



LlPARETRUS PALLENS, 11. Sp. 



Castaneo-flavous, head and legs with a redder tinge ; 

 antennae and palpi flavous. Under-surface moderately, the 

 abdomen more sparsely, clothed ; upper-surface glabrous 

 except for a fringe on each side of pronotum, a few short 

 depressed setae across its apex, and a few inconspicuous 

 setae on clypeus ; hind parts with short, sparse, and incon- 

 spicuous setae.
