eighth decidedly separated at apex, ninth punctate as usual in 

 genus ; lateral border narrow, reflexed, basal border lightly 

 curved on posterior margin, not dentate at shoulders ; marginal 

 channel becoming wider towards apical sinuosity. Prosternum 

 not margined at base ; episterna strongly rugulose. Ventral 

 segments smooth (hardly obsoletely rugulose) ; first with a few 

 punctures along anterior margin. 



Length 16-18, breadth 6-6-75 mm. 



Hah. — North Queensland. (Several specimens sent ))y i\Ir. C. 

 French as coming from the Gulf of Carpentaria.) 



This species is allied to R. liopleurus, Cliaud., l)ut is easily 

 distinguished by its wider and mure depressed form, the 

 prothorax proportionately wider and much more strongly rounded 

 on the anterior part of the sides, the elytra more strongly striate 

 with the interstice more convex — the fifth stria and interstice 

 are hardly less developed than those nearer the suture, while in 

 B. liopleurus the fifth stria and interstice are both very 

 feel)le. 



Genus Dakodilia. 



Darodilia macilenta, n.sp. 



Elongate narrow, depressed ; body shortly pedunculate ; 

 prothorax cordate ; elytra oblong, 4-striate on disc, smooth 

 towards sides ; prosternal episterna feebly longitudinally rugulose ; 

 laV)rum deepl}' emarginate ; mandibles long, hooked, decus 

 sating. 



Black, shining ; undersurface, legs and antennse piceous ; tarsi 

 and palpi reddish. Head long, smooth, convex ; clypeal suture 

 distinctly impressed, a fine puncture towards each extremity ; 

 clypeus smooth ; eyes convex, deeply set in orbits at base ; orbits 

 not protuberant behind eyes. Antennte filiform, long, lightly 

 compressed, a little thicker to apex. Prothorax as long as 

 broad (2-3 x 23 mm.), narrowed to Ijase, e\idently narrower 

 across base than apex, truncate in front and on base above 

 peduncle, subdepressed, evenly and Aery lightly convex ; sides 

 lightly and continuously rounded from aj^ex to base ; basal
