186 Mr. Arthur M. Lea's Revision of the 



impressions in front. Antennae extending almost to apex of elytra, 

 Srd joint dentate, 4th-10th pectinate, 11th long. Prothorax 

 longer than wide, sides and apex rather strongly rounded. Elytra 

 considerably wider than prothorax, smooth ; with scattered in- 

 distinct punctures. Legs long and thin ; basal joint of front tarsi 

 with a black comb on the inner margin. 



Length to apex of elytra 3^, of abdomen 5 mm. 



Hah. Victoria : Fernshaw (National Museum). 



In size and general appearance very close to janthini- 

 pennis, but at once readily distinguished by the scarcely 

 punctured elytra and black basal segments of abdomen ; 

 these, it is true, are reddish at the sides, but in the other 

 species they are entirely red. 



Balanophorus ater, n. sp. 



^. Black; sub-basal joints of antennae and knees obscurely 

 diluted with red. 



Head wide, feebly impressed on each side in front, with a few 

 small scattered punctures. Eyes small but prominent. Antennae 

 glabrous, passing apex of elytra ; Srd joint dentate, 4th-10th 

 pectinate, 11th long. Prothorax moderately transverse. Elytra at 

 base not much wider than prothorax ; indistinctly punctate. Legs 

 long and thin. 



Length to apex of elytra 1^, of abdomen 2 mm. 



Hah. S. Australia (type in Macleay Museum). 



Readily distinguished from all the other species of the 

 genus by its minute size and black prothorax. In the type 

 the front tarsi are missing. 



Genus Carphurus, Er., Entomogr., p. 132 ; Lacord., Gen. 

 Coleop., IV, p. 396. 



This genus may be regarded as the central one of the 

 group of genera having exsertile vesicles and short elytra ; 

 branching off in one direction to Balaoiophorus ; in another 

 to Helcogaster, and in still another to Neocarphurus. It is 

 more numerously represented in species than Helcogaster, 

 but few of them are at all abundant in specimens as are 

 many of the latter genus. 



The genus of a female Carphurus can always be ascer- 

 tained ; but, as noted above, it is not always possible to 

 tell whether a specimen, apparently a male, belonging to
