242 t)N THE AUSTRALIAN CLIVINIDES, 



truncate; wings concave, strongly advanced beyond median part, 

 obtusely rounded anteriorly; guise convex, hardly at all rugulose. 

 Labial palpi with penultimate joint stout, rather short, about 

 same length as terminal; this wide and obtuse at apex. Antennae 

 with third joint shorter than second; joints 4-11 short, hardly 

 compressed. Prothorax smooth, transverse (2-6 mm. x 2-9 mm.), 

 widest a little before posterior angles, greatly narrowed anteriorly 

 (ant. width 2 mm. ), very convex, strongly and roundly declivous 

 to base; sides rounded; anterior angles obtuse; posterior angles 

 obtuse, but marked; basal curve short; border thick, wide and 

 reaching neck at anterior angles; median line weak; anterior line 

 strongly impressed; lateral basal impressions obsolete. Elytra 

 ovate (5-5 x 3'5mm.); strife deep, entire, very coarsely punctate 

 on disc ; interstices subcarinate for whole length, narrow and 

 more carinate on apical declivity. 



Length 10, breadth 3-5 mm. 



Hah. : Queensland — Cooktown (from Mr. French). 



This species agrees in all points of structural detail with C. 

 nyctosyloides, Putz., of which it may possibly be a marked variety, 

 though I regard it as a distinct species. The following differences 

 from C. ny ctosyloides may be noted; the smaller size; more convex 

 form; more elongate head; prothorax more convex, narrower, more 

 strongly narrowed anteriorly; elytra more convex, strias deeper, 

 interstices more convex, especially towards apex. 



Clivina mastersi, n.sp. 



Very large, robust, convex. Head as in C. procera: prothorax 

 smooth, greatly narrowed anteriorly, convex, strongly declivous 

 to base; basal curve short, rounded : elytra oval, smooth on sides 

 and apex; five inner striae impressed towards base, first only 

 entire, fourth and fifth confluent at base; sixth interstice narrow, 

 not carinate at humeral angle,* eighth not visible near apex: 



* The weakly developed submaryinal humeral carina is a continuation of 

 the sixth interstice; it is very narrow and hardly raised.
