conical tubercles on apical slope and punctures (except on 

 sides) less well defined owing to the greater elevation of the 

 interstices. The only male I have seen differs also in having 

 the prothorax without a median carina and the scutellum 

 not elevated, but these may be individual variations. It is 

 evidently abraded, and has numerous minute denticulations 

 showing on the front tibiae. 



Leptops horridus, Lea. 

 A specimen from the Coen River differs from the typical 

 form of this species in being much smaller (11 mm.) and 

 narrower, with the elytral tubercles conspicuously red and 

 more acute; the Catasarc us-\ike tubercle on each side, more- 

 over, is much smaller than usual, although traceable. 



Leptops laticollis, Lea. 

 Mr. G. F. Hill has taken numerous specimens of this 

 species near Darwin, and sent six for examination. These all 

 have the upper-surface apparently glabrous, but really 

 sparsely clothed with short setae. The female differs from 

 the male in having the elytra considerably wider than the 

 prothorax, and with somewhat shorter legs. 



Leptops parvicornis, Lea. 

 Plate xxxix., figs. 146 to 148. 

 Three specimens were photographed to show the differ- 

 ences in size and appearance of this rare species. 



Leptops cacozeltjs, Lea. 

 PI. xxxix., figs. 154 and loo. 

 A specimen from Tarcoola evidently belongs to this 

 species, but has two small conjoined tubercles on the suture 

 near the summit of the apical slope ; on another remnants of 

 tubercles are traceable ; these specimens seem almost to con- 

 nect the species with parvicoimis. 



Leptops crassirostris, Lea. 

 A specimen from Dr. Ferguson, without locality label, 

 may belong to this singular species ; but it differs from the 

 type in having the elytra less suddenly elevated at the base, 

 with six small tubercles there, some obtuse but fairly large 

 ones on the third and fifth interstices, and the punctures 

 larger ; on the prothorax also the granules are larger and 

 better defined. From phymatodis it differs in the rostrum 

 being much shorter, the elytral tubercles much smaller, and 

 the base of elytra very different.
