 grooves, the spaces between shar]>ly eUivated (with the keoled sides

 triangular; elytra broader than the prothorax at the base, each with 

 four raised lines, the two central abbreviated towards the apex, the 

 suture uot thickened ; legs pitchy ; body beneath black, sparingly 

 punctured; antennje, especially towards the apex, sparsely clothed 

 with rich golden-brown hairs. Length 21 lines. 



Smaller and proportionably narrower than the last, and readily 

 distinguished by a miiltitudo of characters, although the habit is 

 nearly the same. 



ArosYLA [Tenebrionida).] 



Head convex and subtriangular in front, slightly elongated behind the 

 eyes. Antennse short, eleven -jointed, gi*adually increasing from the 

 base, the first joint partially concealed by the antennarj' orbit. Eyes 

 large, round, entire. Epistome and lip short, very transverse. Palpi 

 with the terminal joint narrowly triangular. Mentum transverse. 

 Prothorax subcordate, scarcely longer than broad. El}^ra narrow, sub- 

 parallel. Legs moderate ; anterior coxa) large, subcylindrical, greatly 

 exserted ; tibia) spined ; tarsi slender. 



But for the large and greatly exserted anterior coxsd, I should not 

 hesitate to place this genus near Calcar, although the antcnnary 

 orbit is so contracted as to leave the eye perfectly free, and the 

 epistome, although short, is of great breadth and apparently distinct 

 from the front. Whatever its affinities maybe, I cannot myself see, 

 at present, that it can be better placed than near Calcar and Boros. 



Aposyla picea. (PL XVI. tig. 4.) 



A. subelongata, rufo-fusca, nitida, punctata ; autennis ferrugineis. 



llah. Queensland. 



Rather elongate, subdepressed, shining, reddish bro%\Ti ; head convex 

 between the eyes, and slightly constricted behind them, irregularly pimc- 

 tured; antenna) ferruginous; lip with stitf greyisli hairs; prothorax 

 with numerous somewhat coarse punctm*es; scutelluni broadly trian- 

 gular ; elytra scarcely wider than the prothorax, punctured in rather 

 irregular rows ; body beneath and legs reddish-brown. LeUgth 3^ lines. 



Rhypasma [Tenebrionidae]. 



Head rather broad, convex in front, truncate anteriorly, the epistome and 

 lip inserted beneath. Eyes small, oblong, entir«'. Antenn.-c ll-joinird, 

 inserted beneath the broad antounary orbil, half the length of the body,
