while four specimens of H. foveata were taken at Dalveen. Types 

 in the author's Coll. 



Hypaulax puncticollis, n.sp. 



Elongate-obovate, dull black above, nitid beneath, antennse 

 reddish, tarsi with golden tomentum. 



Head: mandibles bifid, epistoma truncate at apex, oblique at 

 sides and continuous with the canthus, limiting suture arcuate 

 and fine, forehead evenly convex, the whole closely and not very 

 finely punctate. Prothorax 4 x 5J mm., subtruncate at apex and 

 base, anterior angles obtuse and scarcely advanced, sides feebly 

 arcuate, abruptly incurving behind, posterior angles obtuse, 

 deflexed and not at all produced or dentate, base and sides with 

 narrow, raised margin, that of the latter with a subangular twist 

 at the point of incurving; disc without foveas or central line, 

 densely and regularly punctate, like the head. Scutellum very 

 small. Elytra : basal border thickened and raised, shoulders 

 obtuse, sides scarcely sinuate at apex; striate-punctate, the striae 

 shallow and unevenly defined, the seriate punctures small, fairly 

 even in size and position (much smaller and closer than in H, 

 orcus or H. ampliatus Bates; about three punctures would go to 

 the width of an interval), interstices almost flat throughout, and 

 distinctly punctured. Abdomen striolate and finely punctate, 

 prosternum coarsely punctate, its process sulcate at the sides, the 

 sulci produced behind the pro-coxae, its apex rounded. Protibiae 

 rather strongly bent and incurved at apex. Bifnensions, 18 x 7mm. 



Hab. — Onslow, West Australia. 



A single specimen in the Melbourne Museum differs from H. 

 interioris Blkb., in (l)its distinctly punctate head and thorax (a 

 character Blackburn could scarcely have left unnoticed had it 

 existed in his species); (2) the unproduced obtuse posterior angles 

 of prothorax, which with H. interioris are " parvis acutis ex- 

 trorsum retrorsumque inclinatis." Moreover, if I have identified 

 H. interioris correctly in a much larger species from La Grange 

 Bay, the abdomen is coarsely and deeply punctate, while the 

 prosternum is finely punctate - the reverse being the case with 

 H. puncticollis. The species differs widely from the other two
