rows of rather large punctures, becoming smaller posteriorly ; 

 interstices with sparse and very minute punctures. Length (ex- 

 cludin^^ rostrum) 5-5 1/2 mill. 



Hab. : N. S. Wales : Clarence River (Belgian Museum). 



In appearance ratlier close to bilmeatus, but larger, rostrum 

 shorter, wider in front (approaching the regular Cossonus type) and 

 with small butconspicuous punctures in front, insteadof impunctate. 

 Tlie strong prot^oracic punctures also do not become so crowded 

 towards the base as to form a depression on each side of the base 

 itself; the coarse punctures at the sides are also rather smaller. 



661. COSSONUS PLATYNOTUS n. sp. 



Flavous red, head and apical half of elytra black; tip of prothorax, 

 club, knees and base of femora slightly infuscate. 



Head with rather small but clearlv defined punctures; inter- 

 ocular fovea not very large. Rostrum rather strongly increasing in 

 width from base to near apex; with a wide and rather shallow but 

 conspicuous median impression, feebly connected with inter-ocular 

 fovea; with dense and rather small punctures. Prothorax xery flat; 

 with dense and rather small punctures, becoming sparser and 

 minute towards middle, but each side of a feeble impunctate median 

 line with a feeble row of larger (but still small) punctures; middle 

 of base with crowded punctures. Elytra very flat, with regular rows 

 of large punctures, becoming smaller posteriorly; interstices appa- 

 rently impunctate, the alternate ones feebly raised. Length 5 1/2- 

 7 mill. 



Hab. : Queensland : Wide Bay; N. S. W^ales : Clarence River 

 (Belgian Museum). 



A very depressed species in colour resembling prceiistns but rea- 

 dily distinguished from that species and vicarius by the very diffe- 

 rent prothoracic punctures; from nigroapicalis its very different 

 rostrum and prothoracic punctures will readily distinguish it. The 

 rostrum although wider in front of than behind the antennae is not 

 so suddenly inflated as in so many species. 



HOPLOCOSSONUS n. g. 



Eyes rat^ler large and conspicuous. Rostrum feebly curved, wide, 

 dilated in front of antennae; scrobes almost meeting on lower sur- 

 face of head. Antennae stout; scape shorter than funicle; funicle 

 7-jointed, first joint subtriangular, the others all strongly trans- 

 verse; club rather briefly ovate. Femora stout, the front pair very 

 stout and very strongly dentate; tibiae each with a strong terminal 

 hook.
