Very distinct from all previously described species, and easily 

 identifiable by its very flat form and beautiful colour. Tlie ely tral 

 striation and punctures somewhat resemble those of C Guerhdi; 

 the colour is somewhat like that of C. basalis, and the antennse 

 are considerably thicker than those of C. insidiator. 



Calochromus brevicornis, n.sp. 



(J. Head, antenna^, under surface and legs sooty-black; pro- 

 thorax, scutellum, elytra (except extreme apex), apex of coxte and 

 base of femora beneath yellow, prothorax tinged with red. Elytra 

 densely clothed with short pubescence ; sides of prothorax, 

 antennae, under surface and legs feebly pubescent. 



I/ead feebly punctate, a wide shallow groove between eyes. 

 Rostrum very short. Antennte scarcely extending to posterior 

 coxse, 1st joint thick, as long as 3rd, 2nd small, round, moderately 

 distinct, 3rd-5th serrate internally, 3rd-llth gradually decreasing 

 in width, and 4th-llth in length. Prothorax scarcely transverse, 

 sirles incurved to middle, apex rounded, base feeblj^ bisinuate, 

 feebly notched in middle, notch invisible from above, slightly 

 wider than apex, posterior angles subobtuse; disc with a rather 

 .shallow groove at base connected with apex by a feeble ridge; 

 sides, especially at base and apex, deeply impressed. Scutellum 

 transverse, apex semicircularly emarginate. Elytra slightly wider 

 than prothorax, very feebly increasing to near apex; densely and 

 regularly punctate, punctures moderately round, subapproximate; 

 each elytron with ten rounded scarcely raised interstices, sub- 

 costate near base. Penultimate segment of abdomen feebly 

 incised. Length 7f, width 2^ mm. 



2- Differs in having shorter and thinner antennae, smaller eyes, 

 prothoracic impression shallower, and simple abdomen. 

 //a6.— Galston, N.S.W. (Dumbrell and Lea). 



The disc of the prothorax could scarcely be called five-areolate. 

 It is not close to any species with which I am acquainted except 

 the following.
