men, and the much stronger femoral dentition. On the elytra 

 of one specimen the clothing is uniform, but on the other 

 it exhibits a feeble tendency to become fasciate. 



SUBFAMILY COSSONIDES. 

 CossoNUS viCARius, n. sp. 



Red ; head and apical half of elytra black, knees and 

 base of femora infuscate. 



Head with dense and rather small punctures; inter- 

 ocular fovea fairly large. Rostrum ratlaer wide at base, 

 suddenly and strongly inflated in front, with a short median 

 impression ; with dense punctures, rather smaller than on 

 head. Prothornx flat, base feebly bisinuate ; with dense and 

 moderately small punctures, towards middle becoming larger 

 (but not very large) and sparser ; middle itself with a feeble 

 impunctate line. Elytra with regular rows of large punc- 

 tures, becoming smaller posteriorly, the interstices each with 

 a row of very minute punctures. Length, 7 mm. 



Hab. — New South Wales: Sydney. 



In general appearance remarkably close to prceustus, but 

 prothoracic punctures much smaller and less uneven at the 

 base ; the elytral punctures are also considerably smaller, 

 although similarly disposed. It should possibly be treated 

 as a variety of 'prceustus, but I have seen no intermediate 

 forms. 



The elytra of the type are quite black at the apex, but 

 where the two colours join (slightly nearer base than apex) 

 the black becomes less intense, so that the two colours are 

 not sharply defined. The rostrum and antennae, although 

 red, are slightly darker than the prothorax, but this also is 

 darker at the apex than elsewhere. 



A smaller specimen (5 mm.) differs from the type in 

 having the prothorax black, the black on the elytra slightly 

 advanced towards the base, and quite sharply defined, and 

 the side pieces of the mesosternum blackish, but I can find 

 no structural differences between it and the type. 



CoSSONUS NIGROAPICALIS, n. Sp. 



Of a rather bright-red, head and apical half of elytra 

 black ; apex of prothorax, knees, and base of femora slightly 

 infuscaite. 



Head smooth and almost impunctate ; interocular fovea 

 rather large. Rostrum smooth and convex, without a 

 median line, siiddenly and strongly inflated in front of an- 

 tennae ; with small, sparse, and irregularly-distributed punc- 

 tures. Prothorasc not very flat ; with dense and not very 

 small punctures ; with an impunctate median line (appearing 

 almost like a carina), on each side of which are some coarse
