sides much less strongly rounded and recurved. (N.B. — The 

 figure of B. reticulatus, Ann. Mag. Nat. Hist. 1869, pl.x. fig. 6, 

 exaggerates the recurved sides). The elytra are less coarsely 

 rugose, but the punctures above and below are larger and more 

 distinct. The abdominal punctures especially differ; in B. reticu- 

 latus they are largely confluent and longitudinally rugose; in B 

 kosciuskoamts they are uniformly round and separate. My 

 specimen of B. reticulatus Pasc, is from Fernhill, Victoria; and 

 was compared with the type in the British Museum by myself. 

 Two other specimens from Buffalo Mountains, Vic, differ from 

 the Fernhill specimen in having a less widely reflected margin to 

 prothorax, and more distinctly raised costse on the elytra. Four 

 specimens of B. kosciuskoanus are before me, of which I consider 

 there are two of each sex. If this be correct, the apparent males 

 are smaller, narrower, more convex than the females, with the 

 penultimate joint of the front tarsi less transverse. 



Cardiothorax rotundicollis, n.sp. 



Flat, elongate-ovate. Black, moderately nit id. 



Read and front with typical markings. Antennae short and 

 stout, with apical joints less markedly thicker than the basal 

 joints, as in most of its allies, and clothed with reddish hairs. 

 Prothorax almost flat and widely foliate at sides, and with a 

 markedly wide raised border extending all round except at base, 

 and middle part of apex. Much narrower at base than apex, 

 widest at middle; base slightly curved, with the concavity towards 

 the elytra and basal edge depressed. The front very sinuate, 

 with middle of disc advanced and anterior angles well produced 

 forward to meet the rounded sides at an obtuse angle. Sides 

 widely and regularly rounded, rather abruptly contracting at base 

 posterior angles obtuse and subobsolete. Central channel deeply, 

 impressed throughout, except on apical border. On each side of 

 this two deeply lineate impressions abruptly ending forward but 

 produced at right angles to meet central channel behind. Foliate 

 sides divided from disc by curved impression. Elytra ovate, 

 deeply and regularly striate. Intervals sharply raised, about as
