other male one side is subangulate (much as on heterodoxa)^ 

 but the other is very feebly tridentate. On one male the 

 abdomen is not much darker than the legs, except that the 

 basal segment is greenish in the middle, on a second specimen 

 only the apical segment is pale, the rest of the under-surface 

 being more or less brassy ; on the female the abdomen is red- 

 dish, with a slight metallic gloss, and the sterna are golden- 

 red. The elytral pubescence is not dense, but being suberect 

 and almost evenly distributed in subseriate rows, it is quite 

 conspicuous ; the prothorax, however, is almost glabrous. On 

 the female the median line of the head is well defined, but 

 on the male it is feeble. On the male the pygidium appears 

 to add a short sixth segment to the abdomen. About the base 

 and on the apical slope most of the elytral punctures are 

 separately impressed, but on the slope they are confined to 

 well-defined striae, although these (except near the suture) 

 are somewhat irregular. 



Geloptera (type tuherculata). 



Terillus (type rotundicollis ) . 



Alittus (type foveolatus). 



Agetinus (Agetus n. pr. ; type suhcostatitsj. 



Hypoderes (type denticollis). 



Of the above genera their typical species are indicated, 

 and of these tuherculata is a well-known and abundant species 

 in Western Australia; subcostatus is a well-known and abun- 

 dant species in South Australia, Victoria, and Tasmania ; and 

 denticollis is a well-marked species, occurring in northern New 

 South Wales and southern Queensland. I am unacquainted 

 with rotundicollis ; but elsewhere am commenting upon 

 foveolatus. 



According to Lefevre, the genera in question all agree in 

 the following details, regarded by him as generic : — "Proster- 

 nal episterna with front margin straight or concave. Base of 

 prosternum straight or arcuately truncate. Femora unarmed. (^i) 

 Tibiae (at least the middle pair) longitudinally carinate, the 

 four hind ones not notched near outer apex. Claws appendicu- 

 late." And a table based on differences as noted by himself 

 and Chapuis would be as follows : — 



Upper-surface clothed. 



Prothorax with sides entire. 



Prothorax with sides straight ... ... ... Alittus 



Prothorax with sides rounded in middle ... Terillus 



Prothorax with sides more or less dentate or un- 

 dulated ... ... ... ... ... ... Hypoderes 



Upper-surface glabrous. 



Antennae with joints two and three subequal ... Agetinus 

 Antennae with these joints very different in length G-eloptera 



(81) Several species with armed front femora have been referred 

 to Geloptera.
