first two are very slight, while the descriptions of 

 both will fit Macleay's species. The author's iden- 

 tification of chalceus (p. 238 of monograph) was a 

 mistake. 



C. lachlanensis, Cart.=var. of caperatus, Pasc. 



Otrintus fergusoni, Cart.=C politicollis, Bates. 



Cardiothorax clypeatus, n. sp. 



Elongate-ovate ; violet-bronze above, black beneath, an- 

 tennae piceous, apex of tibiae and under-side of tarsi clothed 

 with golden tomentum. 



Head — Epistoma oblique at sides, semi-circularly excised 

 in the middle; suture straight, and, with the usual frontal im- 

 pression, sharply defined and straight at sides, with a wide 

 central depression ; antennae stout, scarcely reaching base of 

 prothorax, punctate and bearing short golden hairs, joint 3 

 shorter than 4-5 combined, 5-10 gradually wider and rounder, 

 11 ovate-acuminate. Prothorax, 4x5 fvix.J mm., widest in 

 front of middle, apex arcuate, front angles rounded and 

 slightly produced, sides widened and rounded anteriorly, slightly 

 sinuately converging behind ; posterior angles acute, deflected, 

 and slightly but evidently dentate ; base widely angulate in 

 the middle; basal and apical borders narrow, lateral border 

 wide and reflexed ; foliate margins moderately wide, obsolete 

 at base, bearing two large punctures (not setiferous) ; disc 

 apparently smooth with sharply impressed medial line, cutting 

 the base but not the apical border. Scutellum, subsemi- 

 circular, smooth, with triangular depression behind. Elytra 

 little wider than and two and a half times as long as prothorax ; 

 shoulders subobsolete, or only represented by a narrow arcuate- 

 epipleural fold; striate with nine striae on each, the lateral 

 two or three but faintly impressed ; intervals nearly flat (ex- 

 cept at apex and sides), smooth and of equal width. Epip- 

 leurae and abdomen smooth, prosternum transversely striolate ; 

 femora without sexual distinctions ; tibiae, especially of male, 

 triangularly-emarginate at apex with two sharp spines, the 

 interior longer and stouter. Dimensions — 16 x 5 mm.

Some half-dozen specimens were taken by the author in: 

 January, 1912, and were at first determined (and possibly 

 given away) as C. politicollis, Bates. On observing the dif- 

 ferences, especially in the clypeus, between two species, I sent 

 one of each to the British Museum for comparison with the 

 type of politicollis. Mr. Blair has very courteously complied 

 and replies, the "smaller with very narrow margins to pro- 

 thorax and the clypeus produced in the midd! b agrees with
