182 Arthur M. Lea : 



Hah. — Tasmania: vSwansea. One specimen from a nest of 

 Colobopsis ga-sseri (A. M. Lea). 



Tlie males have the front tibiae dih^ted as in gulosus, but the 

 head and prothorax are much darker in that species. The club 

 of the antennae is rather stouter than in the preceding species, 

 but is otherwise the same, the sides of the prothorax are rather 

 more densely clothed. The elytra are somewhat wider and the 

 whole insect slightly larger. 



From some directions the elytra appear to be of the same 

 shade of colour as the prothorax, but from others they appear 

 to be paler. 



Scydmaenus daveyi, n.sp. 



Of a bright castaneous, appendages paler. Upper surface 

 with sparse pubescence, but becoming longer and denser on 

 sides of prothorax. 



Head smooth, eyes distinct but not prominent ; antennae as 

 in clientulus, except that the eighth joint is somewhat smaller, 

 although distinctly part of the club. Profhorar slightly longer 

 than wide, sides widest and gently rounded near apex, base with 

 four large punctures or small foveae, the two on each side shal- 

 lowly connected with each other, but the two median ones 

 separated by a feeble ridge or carina. Elytra oblong-ovate, 

 rather strongly inflated to near middle; basal impressions 

 rather shallow ; with sparse indistinct punctures. Front tibiae 

 moderately inflated towards apex. Length 4-5th mm. 



Hah. — -Victoria: Forrest, Geelong, in nests of a small black 

 ant Colohnpsisi (H. W. Davey). 



Close to caHaneogl aher . but antennae thinner, elytra not quite 

 so highly polished and not quite glabrous. From colobopsis it 

 differs in being smaller, elytra with sparser and much shorter 

 clothing, sides of prothorax much less densely clothed, and 

 antennae thinner. 



Scydmaenus (jhtbripennis, n.sp. 



Head and prothorax blackish brown, under surface somewhat 

 paler ; elytra brightly castaneous, suture somewhat darker ; 

 appendages somewhat, the tarsi quite, flavous. Head at base, 

 and prothorax at apex and sides, with fairly dense reddish hair 

 or fine setae; rest of upper surface almost or quite glabrous.
