two shallow impressions on the discs near the base are 

 also wanting- in the present species. Elytra narrower, 

 less sinuous at the base, more convex, not so wide, rela- 

 tively, behind the middle, with the rows of impressions 

 much smaller and more punctiform ; the punctures more 

 or less connected in line by a faint stria, and the inter- 

 vals flatter. Prosternal process squarely truncate be- 

 hind. Body shining black beneath, with the legs entirely, 

 the antenna), and the labrum castaneous.

3. Hypaulax tarda, n. sp. 



Length 7 lines. Oblong, black, subnitid. Head broad, 

 but little convex, more visibly punctate than in the two 

 preceding species, the labrum very coarsely so ; epistome 

 separated from the front by a sub-angulate line ; cheeks 

 with a simple curved linear groove, not terminating in 

 a pit or fovea, nor extending" so far across as in the pre- 

 ceding species: mentum having- its anterior angles 

 obliqviely truncate, strongly notched at the apex, con- 

 tracted behind, obscurely furrowed down the median 

 line, with a small wing-like expansion (obscurely visible 

 without dissection) on each side at the back ; labium broad- 

 ly emarginate in front, ciliate. Thorax wider than long, 

 finely and sparingly punctate, convex in front and down 

 the middle, depressed on the discs, with three or four 

 transverse shallow impressions thereon, and another 

 long, transverse and wrinkled, before the middle ; mo- 

 derately rounded at the sides, the fore angles bent down, 

 the hind prominent and acute ; lateral margins slightly 

 sinuous in the middle. Scutellum very small, convex, and 

 strongly transverse. Elytra short, scarcely broader than 

 the thorax at the base, which is sinuous and thickly mar- 

 gined ; of a similar shape to the preceding species, but a 

 little more suddenly declivous behind; scarcely depressed 

 at the shoulders, with the humeral angles rounded ; nine 

 rows on each elytron of large rounded punctures, 

 arranged as in the preceding species, the intervals quite 

 flat. Metasternum very short; prosternal process obtusely 

 pointed behind. Legs and antennas rather short ; fore 

 and intermediate tibiffi moderately arched. Body be- 

 neath, and legs, shining black, with the tarsi, antennae, 

 and palpi castaneous.
