172 NOTES ON AUSTRALIAN COLEOPTERA, 



prothorax), its joints unusually stout, moniliform, 3rd slightly 

 longer than 4th, the apical four considerably and successively 

 widened, the last oval and large. Prothorax 2x2^ mm., apex 

 arcuate, base subtruncate, widest at middle, sides well rounded 

 and sinuate behind; anterior angles obtuse, posterioi acute; disc 

 very coarsely punctate, the punctures close on the subexplanate 

 margins, more distant on central part; with two discal fovese and 

 other smaller depressions, and with a slight rugosity near pos- 

 terior angles. Elytra wider than prothorax at base, and twice 

 as long, shoulders rounded, sides subparallel to beyond the 

 middle: striate-punctate, with nine deeply impressed stria?, con- 

 taining round, moderately large, closely-placed punctures; in- 

 tervals subconvex and distinctly punctate, the 3rd and 5th much 

 wider than the rest and bearing setiferous impressions. Whole 

 underside punctate, the Hanks of prosternum and epipleurse 

 coarsely so. Dimensions: 6^-7x24 mm. 



Hab.— Exeter, N.S.W. (H. J. Carter). 



Two examples, 1 think the sexes, taken by me in November, 

 11)11. The species comes nearest B. cheesmani mihi, in its wide 

 and depressed form, but is easily distinguished by the following 

 combinations: coarsely punctate surface, brilliant colour, wide 

 3rd and 5th elytra! intervals, and robust antennae. In B. chees- 

 mani the elytral intervals are quite Hat, the striae very fine, and 

 seriate punctures small. 



Types in Coll. Carter. 



Amarygmus incultus, n.sp. 



Ovate, moderately convex, black, nitid. 



Head minutely jjunctate; eyes rather widely separated (at least 

 full width of one eye); antennas with last five joints considerably 

 enlarged, 7-10 rhoinboidal. Prothorax with sides arcuately con- 

 verging from base to apex, anterior angles slightly advanced and 

 (seen from above) acute, posterior widely obtuse; disc lajvigate, 

 or only microscopically punctate, with the faintest suggestion of 

 a median line. Scutellum triangular, finely punctate. Elytra 

 convex, finely striate-punctate, intervals quite flat and impunc-
