piceous. Head with frontal impressions diverging strongly back- 

 wards as far as back of eyes ; the eyes hemispherical, very promi- 

 nent. Prothorax very little wider than head with eyes, trans- 

 verse (1 X 1-3 mm.), cordate, convex, widest before the middle 

 (at anterior marginal puncture), evidently narrower across base than 

 in front, truncate in front and behind ; sides a little obliquely 

 (hardly roundly) narrowed in front to anterior angles ; roundly 

 narrowed behind anterior marginal puncture, strongly sinuate 

 posteriorly and meeting the base at right angles ; basal 

 angles acute, prominent ; lateral border narrow, sharply 

 reflexed ; a deep fovea on each side near the l)asal angle, this 

 fovea margined externally by a short lightl}'^ raised carina joining 

 the border at the basal angle ; median line linear, distinctly 

 marked. Elytra ovate (2-75 x 1-8 mm.); sides lightly rounded, 

 a little widened behind the shoulders ; apex evenly and widely 

 rounded ; shoulders rounded, not marked ; seven strongly punctate 

 but lightly impressed stria? on each elytron, exclusive of the 

 marginal stria and the scutellar striole ; interstices flat, third 

 lightly bipunctate on disc ; scutellar striole long, punctate; marginal 

 channel lightly punctate behind shoulders ; border finely reflexed, 

 a little thickened and turned back to form a slight prominence at 

 base of fifth stria. 



Length 4-4-75, breadth 1-8-2 mm.

The female is rather darker coloured than the male, both in 

 the green, and the pale apical marking of the elytra. The pale 

 part of the elytra extends round the apex a little way along the 

 sides and is about the width of the lateral declivity. This seems 

 a very distinct species among the described species of Australian 

 Bembidiides ; comparing it with B. jacksoniense, Guer.,* which it 

 resembles in the colour of the elytra, and in company with which 

 I have taken it ; its greater size and ver}?^ differently shaped 

 prothorax are apparent and conspicuous differences. I found it
