the separating suture arcuate and clearly denned, forehead 

 convex, less strongly punctate than, but equally densely as, the 

 epistoma ; antennae with joint 3 as long as 4-5 combined, 4-7 

 obconic, 8-10 elongate-ovate, 11 ovate-acuminate. Prothorax 

 4\ x 1\ mm., widest at middle, arcuate at apex, feebly 

 bisinuate at base, wider at base than at apex, sides moderately 

 and evenly rounded, slightly sinuate at hind angles, anterior 

 angles subrectangular and scarcely produced, posterior acute, 

 dentate, and pointing obliquely outwards; lateral border 

 strongly thickened and round, produced but narrowed and 

 abruptly ending on anterior part of front angle, rather widely 

 channelled inside this border ; disc very densely and finely 

 punctate, like the forehead, with two faint foveate impressions 

 on centre of disc, and some equally faint transverse impressions 

 near base. Scutellum very transversely triangular. Elytra 

 of same width as elytra at base, shoulders widely rounded, 

 slightly obovate, with narrow horizontal margin and renexed 

 border, each elytron with four wide and little raised costae, 

 Desides the sutural costa, the fourth separated from the margin 

 by a row of large punctures, intervals vermiculately rugose 

 and strongly punctate, the punctures uneven in size and some- 

 times — as at the suture— in a lineal formation, the costae 

 somewhat crenulate from the large, but irregular, punctures 

 at their sides. The whole under-side finely and closely punc- 

 tate, prosternal process produced, channelled down its middle, 

 but not bifid at apex ; mesosternal notch triangular ; posterior 

 intercoxal process widely circular, its border raised : submen- 

 tum widely notched in the middle, and with a small flat tooth 

 pointing forwards. Dimensions — 18 x 9 mm. 



Hab. — New South Wales : Howell (Inverell district). 



A specimen sent me by Mr. J. F. Stephen, to whom I 

 dedicate it, differs from JE . mnrc/irii'pennis, Cart., in its more 

 even and densely punctate head and prothorax, the longer 

 third joint and lighter colour of antennae, the wider anterior 

 angles of prothorax, its thicker border, more dentate hind 

 angles, the elytral costae more defined, etc. It is much further 

 removed from all the other species of the genus. Type in 

 author's collection. 



^Ethalides coxi, n. sp. 



Widely ovate; nitid-black above, rather dull black 

 beneath. 



Head very similar to JE '. stejiheni, except in the following 

 particulars : — Epistomal suture straight, its surface more 

 horizontal; canthus more raised and strongly furrowed within; 

 punctures more widely separated; forehead more rigid
