248 NEW SPECIES OF AUSTRALIAN COLEOPTERA, II., 



definite, deeply striated, with six striae on each elytron, all except 

 the sixth well marked to the apex and not confluent. Interstices 

 convex, straight and equal. On sides and epipleurae are three 

 lines of punctures. Two punctures much larger than the rest on 

 side, about equal distances apart, and the same distance respect- 

 ively from the base and apex. Legs thin, tarsi nearly straight, 

 femora unarmed. Dimensions 10 x 3d mm. 



Hah.— Clyde River, N.S.W. (Mr. Masters). 



Through the courtesy of Mr. Masters I am able to describe 

 this species, of which the two type specimens are in the Macleay 

 collection, captured by Mr. Masters himself. I am unable to 

 speak definitely as to the sexes of these, the abdomen of one 

 specimen being absent, nor are there any marked sexual char- 

 acters in the tibiae and femora. The small size, light colour, the 

 triangular depression on prothorax, and the two large punctures 

 on sides of elytra are sufficient to point out the identity of this 

 species. 



Cardiothorax rugosus, n.sp. 



Elongate-ovate, black, opaque. Legs, abdomen, and basal half 

 of antennae shining black. 



Head: epistoma rather flat and longitudinally rugose; frontal 

 impression large with front and sides rectangular, base 

 rounded; with two large shallow foveas on its centre. Antennae 

 about the length of head and prothorax combined, rather slender 

 at base, thickening towards apex. Joints 1-7 shining, 8-11 dull 

 black, 3rd joint much longer than 4th. Prothorax very little 

 convex, transverse, widest at middle, finely bordered throughout, 

 apex emarginate, front angles wide, obtusely pointed, reaching 

 nearly to the eyes; foliaceous margins wide, flat and of nearly 

 equal width to the base, separated from disc by a broad and deep 

 sulcus; sides gently rounded anteriorly, more abruptly posteriorly, 

 where they are suddenly constricted towards the wide, subrect- 

 angular, dentate hind angle; this angle sometimes more acutely 

 produced outwards by the thickened border. Base much narrower 

 than apex and widely angular. Disc with medial channel evenly 

 and strongly marked throughout, but not interrupting front or
