532 MISCELLANEA ENTOMOLOGICA, NO. IV. 



25. Pterohel^eus hirtus, n. sp. 



Oblong, black, sub-nitid, the upper surface rather thickly clothed 

 with erect soft haii's. Head rugosely punctate, clypeus broadly 

 rounded, smooth and slightly rellexed, eyes about their diameter 

 apart. Thorax transverse, thinly punctate, the anterior angles 

 produced and angularly rounded, the margins broad, thinly 

 punctate, narrowly raised on the edge, and of a piceous colour, the 

 posterior angles acute and slightly pointed backwards, the base 

 bisinuate, with a transverse canal on the central lobe, and a deep 

 fovea at the middle of the emarginate part on each side of it ; 

 the disk is moderately convex with the median line rather faintly 

 marked, and a shallow groove marking the line of separation 

 between the disk and the margin on each side. Scutellum slightly 

 transverse, triangular, rounded behind. Elytra of the width of, 

 and three times the length of the thorax, parallel-sided for two- 

 thirds of the length, and then narrowing to the apex, the disk very 

 closely seriate-punctate, the punctures large, deep and crowded in 

 17 rows, every second interstice costate and smooth, the lateral 

 margins narrow, uniform in width throughout, and smooth with 

 reflected edge. Undersurface of body nitid, striolate-punctate 

 and thinly clothed with decura.bent hair of a yellowish colour ; 

 the prosternum terminates in a lai-ge flat process, rounded at the 

 apex and fitting into the mesosternum, which is longer than usual 

 in the genus. The legs are stout and setose, the tarsi very short, 

 the three first joints very broad, bilobed and largely padded with 

 masses of red hair. 



Long. 10 lines, lat. 5^ lines. 



Hab. — New South Wales. 



The form of the tarsi is the most remarkable thing in this, in 

 many respects, curious insect. It might very properly be con- 

 stituted into a genus.
