numerous punctures. Pygidmm with fairly dense punc- 

 tures, a depression in each basal angle. Front tibiae 

 wide and strongly tridentate ; basal joint of hind tarsi longer 

 and stouter than second. Length, 8-9 mm.

The male has longer and thicker legs than the female, 

 and the sexes differ to a slight extent in the prothorax, its 

 greatest width in the male being postmedian, in the female 

 antemedian, in the male also it is less transverse than in the 

 female, hence the characters used in Blackburn's tablet 14 ) are 

 unsatisfactory; but of the species known to Blackburn it 

 seems closest to tetricus, from which it differs in its smaller 

 size, much smaller elytral punctures, less convex elytral inter- 

 stices and red legs ; it is without the metallic gloss of micans.

and differs in other respects from that species. The median 

 line of the prothorax is either absent or vaguely impressed 

 for a short distance near the base. Countless thousands of 

 specimens of this species are sometimes washed up on the 

 beaches near Hobart, after sultry nights. 



PSEUDOHETERONYX SETICOLLIS, 11. sp. 



PI. xxvi., fig. 61. 



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

 dish. Head and prothorax with dense and extremely short 

 suberect setae ; abdomen and pygidium with longer and 

 sparser setae, parts of legs, front wall of clypeus, angles of 

 prosternum, and margins of elytra with still longer setae, or 

 stiff hairs. 



Head smooth and impunctate at base, elsewhere with 

 crowded (but not confluent) and rather shallow punctures of 

 moderate size. Clypeus with punctures as on rest of head, 

 front margin feebly incurved to middle, hind suture appear- 

 ing as a narrow sinuous elevation. Antennae eight-, club 

 three-jointed. Prothorax widely transverse, sides gently 

 rounded, base very feebly bisinuate, front angles produced 

 and acute, hind ones lightly rounded off, median line feeble ; 

 punctures somewhat smaller than on head, but quite as dense. 

 Elytra with sides gently and apex widely rounded ; with 

 rather feeble relics of striatien ; punctures slightly larger, 

 sparser, and more sharply defined than on prothorax. 

 Pygiditim with irregularly distributed, asperate punctures. 

 Front tibiae strongly tridentate; basal joint of hind tarsi 

 slightly longer than second, each claw with a strong basal 

 appendix. Length, 11 '5- 15 mm.
