8S LOED HOWE ISLAND. 



Head rounded in front, extremely finely punctured ; the male with two 

 horizontal pointed horns above the eyes ; the female with two similarly- 

 placed processes, which are blunt at the extremity. Antenna? dark ferru- 

 ginous, finely pubescent. Prothorax at the base about twice as broad as 

 long, extremely finely and rather closely punctured, with two indistinct 

 oblique impressions behind, one on each side of the middle. Scutellum 

 broadly transverse, extremely finely punctured. Elytra strongly convex, 

 finely punctate-striate, the stria? not very deeply impressed and abbreviated 

 posteriorly, the interstices broad, slightly raised, and extremely finely and 

 rather sparingly punctured. Underside pitchy black, somewhat shining, 

 finely and sparingly punctured. Legs dark ferruginous, tarsi paler. Length 

 6 — 6^ mm. 



Except as regards the development of the processes on the head, the sexes 

 of this species do not differ perceptibly. It appears to be very distinct from 

 the described Australian forms; but I have seen a Platydema from Bowen, 

 Queensland, and Kiama, New South Wales, which agrees with it in every 

 point except that the elytral stria? are less strongly marked.

 Saraqus exulans, Pascoe, Journal Entom., II, p. 406 (1866) ; Macleay, 

 Proc. Linn. Soc. N.8.W., (2) II, p. 667 (1887). 

 An abundant species, which varies from 10 to 14 mm. in length. 



*Sakagus gulielmi, sp. nov. 



Elongate-ovate, moderately convex, pitchy black, somewhat shining; pro- 

 thorax finely and densely rugulose punctate ; elytra closely and rather 

 strongly lineate-punctate. 



Head transverse, rather finely rugulose punctate ; clypeus with the sides 

 sloping, scarcely emarginate in front. Antenna? dark ferruginous. Pro- 

 thorax transverse, considerably narrowed and broadly emarginate in front, 

 finely and closely rugulosely punctured on the disc, more evidently rugulose 

 near the sides ; the lateral margins broad and not clearly defined. Scutellum 

 very finely and sparingl} r punctured. Elytra rather strongly and somewhat 

 irregularly lineate-punctate, the punctures less impressed posteriorly, the 

 suture slightly raised. Underside pitchy black, somewhat shining ; abdominal 

 segments minutely punctured and finely aciculate at the sides. Legs pitchy ; 

 the tibia and tarsi ferruginous. Length 14 — 17mm. 



Summit of Mount Ledgbird (2,500 feet), under stones ; also found on the 

 low-lying lands. 



This species may be distinguished from Saragiis exulans. with which it 

 has hitherto been confused in more than one Sydney collection, by its 

 comparatively longer and much more strongly punctured prothorax, and its 

 more distinctly punctured elytra. In form it is more elongate, and usually 

 it is larger in stature. This species,which, like the last, is probably endemic, 

 i3 dedicated to the Hon. "William Macleay, M.L.C., who has recently pub- 

 lished an exhaustive review of the species of Saragus and the allied genera of 

 Hela?ina?. 



*Xyctobates stereha, sp. nov. 



Plate TI, f. 1. 



Elongate, robust, black, shining, strongly convex ; prothorax broadly trans- 

 verse, slightly narrowed behind, with a distinct median line ; elytra very 

 broad behind, narrowed in front, strongly punctate-striate, the interstices 

 broad and convex. 



Head and clypeus rather finely and sparingly punctured, the latter with 

 an indistinct transverse impression in the middle. Antenna? dark ferru-
