large almost circular fovea, extending from base to the 

 slightly overhanging pygidium; with two short medio-apical 

 processes. Metasternum sloping upwards from base to beyond 

 the middle, and then strongly sloping downwards to apex. 

 Front and hind tibiae somewhat dilated, the middle pair 

 short, strongly curved, and terminated by a sharp spur. 

 Length, 2 J mm. 



Hab. — Queensland: Cairns district, from a nest of ants 

 (F. P. Dodd). Type (unique), I. 8538. 



The type was somewhat mouldy, and on cleaning it pos- 

 sibly some of the pubescence was removed; the species, 

 however, is one of the most distinct in the genus; it is a 

 rather large dark one, at first glance somewhat resembling, 

 but really very different from, dentiventris and lopliosternus ; 

 it is about the size of dilaticornis, but the abdomen is very 

 different, antennae smaller, etc. Structurally it is close to 

 raffrayi, but is much darker, the under-surface of the abdomen 

 with a more sharply defined excavation (without sub- 

 basal armature), and antennae slightly shorter. The antennae 

 are narrow at the base, then suddenly and strongly dilated 

 and flat, near the apex they become narrower and deeper, 

 with the apex itself almost circular, the greatest width is 

 almost median ; seen from below the basal two-thirds appear 

 to be finely striated. The medio-basal impression of the pro- 

 notum is, for the genus, decidedly feeble, but is quite distinct. 

 The excavation on the under-surface of the abdomen is 

 actually of greater extent than the one on the upper-surface ; 

 the summit of the metasternal elevation is not spinose, but 

 from some directions appears to be slightly angular. 



CUCUJIDAE. 



Laemophlaeus blackburni, Grouv. (1902). 

 L. frencki, Blackb. (1903). 



There was not time for the description of blackburni 

 to be noted in the Zoological Record when the description 

 of frenchi was sent for publication; otherwise the late Rev. 

 T. Blackburn would certainly not have redescribed this 

 remarkably distinct species. 



SCARABAEIDAE. 



Neso flavipennis, Macl. (formerly Platydesmus). 



N. yorkensis, Blackb. 

 N. planicollis, Blackb. 



The late Rev. T. Blackburn has already (5) referred to 

 planicollis as a synonym of flavipennis; but he was under the 



(3) Ante, 1907, p. 274.
