Head with small crowded punctures, somewhat sparser 

 in middle than in front, clypeus short, with larger and much 

 sparser punctures than between eyes, sides strongly rounded 

 and rapidly decreasing to apex, which is very feebly incurved 

 to middle, and with angles widely rounded off. Antennae 

 seven- jointed. Prothorax with sides rather strongly rounded 

 and produced outwards towards base, hind angles widely 

 rounded off, the front ones produced and acute, median line 

 briefly and vaguely indicated; surface shagreened, and with 

 rather small and not crowded punctures. Elytra with punc- 

 tures much as on pronotum ; geminate-striae well-defined ; 

 with a conspicuous, finely corrugated apical membrane. Hind 

 parts with small shallow punctures. Front tibiae strongly 

 bidentate ; basal joint of hind tarsi slightly longer than 

 second. Length, 6-7 mm. 



Hab. — Queensland: Cunnamulla (H. Hardcastle). Type, 

 I. 7865. 



Readily distinguished from all others of Group 19 by its 

 bidentate front tibiae. In general appearance it is strikingly 

 close to pallidus and unidentatus (of Group 13), but those 

 species have nine- jointed antennae, whilst on the three 

 specimens before me of the present species the antennae are 

 easily seen to be but seven- jointed. The upper-surface has a 

 slight pruinose gloss ; the pronotum is very narrowly inf uscated 

 on all its margins, but the infuscation is invisible to the naked 

 eye, the scutellum also has its margins very narrowly 

 inf uscated. 



Automolus. 



I cannot quite follow Mr. Blackburn in his table of this 

 genus (ante, 1906, pp. 279-281), as regards the clothing of the 

 head and pronotum of the species of BBB being "at most 

 fine adpressed sparse hairs" ; on gramdatus and humilis the 

 hairs are dense and stout (more or less setose in character), 

 but being adpressed they have a very different appearance to 

 the erect hairs of the other groups ; but this is liable to 

 alteration by maltreatment, as has been already commented 

 upon under ordinatus; two specimens of valgoides before me 

 also have the clothing of the head and pronotum decumbent. 

 Moreover the clothing of the pronotum quite commonly varies 

 in colour, so that it is not advisable to place much reliance 

 on this as a distinguishing feature. 



Automolus alpicola, Blackb. 



Many specimens from New South Wales agree perfectly 

 (sex for sex) in structure with two co -types of this species, 

 but have most of the clothing of the pronotum black ; by the
