punctures that become larger and more crowded towards the 

 base. Elytra with regular rows of large punctures, becoming 

 smaller posteriorly ; the interstices apparently without jDunc- 

 tures. Length, 4-5 mm. 



Hah. — Queensland: Cairns (11. Hacker). 



In general appearance very close to pni^usfits and the 

 preceding species ; but readily distinguished therefrom by the 

 rostrum and prothoracic punctures. 



CossoNUS Hackeri, n. sp. 



Black; appendages dark-reddish-brown. 



Head with rather dense and not very small punctures, 

 smaller and sparser on forehead than in front ; interocular 

 fovea very shallow and indistinct. Rostrum wide at base, 

 and almost regularly increasing in width to apex, with denser 

 and coarser punctures than on head ; very shallowly depressed 

 along middle. First joint of funicle slightly, all the others 

 strongly, transverse ; club rather short, continuous with 

 funicle. Frofhorax depressed, base rather strongly bisinuate, 

 with dense and not very small punctures, becoming sparser 

 towards middle, middle itself with an irregular impimctate 

 space (not a line). Elytra feebly convex, no wider than 

 widest part of prothorax ; with regular rows of f aii'ly large 

 (but for the genus decidedly small) punctures ; the inter- 

 stices each with a row of very distinct punctures, but at base 

 each row increasing to two, three, or four in number, and 

 very irregular. Under surface with moderately dense and 

 not very small punctures, sparser and smaller in middle than 

 at sides. Metasternum shorter than two following segments 

 combined, these with a rather narrow depression common to 

 both. Femora very stout, tibiae short, with a fairly strong 

 subapical tooth in addition to the terminal hook. Length, 

 5J-7 mm. 



Hah. — Queensland: Coen (H. Hacker). 



A rather aberrant species, but I have not considered it 

 advisable to propose a new genus for its reception. The ros- 

 trum is no wider at the apex than in many other species, but 

 is much wider at the base and is not suddenly inflated at 

 the antennae, so that it appears to increase almost regularly 

 in MTidth from base to apex. The scrobes are rather abruptly 

 turned under the rostrum and almost meet, and the lower 

 surface of the head (when viewed from the sides and with 

 the antennae removed) appears to be separated from "the ros- 

 trum by a notch. 



The strong rows of punctures on the elytral interstices, 

 and the comparatively small ones in the regular rows, readily 

 distinguish the species from all previously-described ones from 

 Australia.
