striolate. Tibiae straight, femora unarmed, posterior tarsi rather 

 short, claw-joint longest. Dimensions'. lo x 7 mm. 



Hah. — Southern Cross, West Australia. 



A single specimen, 5, was given to me by that very enthusiastic 

 collector, Mr. H. W. Brown, amongst some Chalcopteri, which it 

 somewhat resembles, except in the structure of head and thorax. It 

 differs from 0. vittata Westw., (a specimen of which is before me) 

 in the following respects : (1) Colour less brilliant; (2) body more 

 convex and robust; (3) prothorax with nitid spaces, the sides much 

 more widely rounded, front angles wider, margins less refiexed; 

 (4) elytral intervals more strongly punctured. 



The prothorax is very similar, in form and colour, to that of 

 Frojjhanes chalcopter aides Cart., which is a much larger insect; 

 the elytra are similar, in shape and colour, to those of Chalcop- 

 terus polychromus Pasc, but the seriate punctures are less dis- 

 tinct. Type in the Author's Coll. 



OLISTH.ENA KUF0-.ENEA, n.sp. 



Ovate, slightly convex; head and prothorax castaneous (margins 

 rufous), elytra green-bronze; antennae, legs, and underside pale 

 red. 



Head rather deeply enclosed in prothorax, epistoma short, round 

 in front, widely impressed behind, evidently and clearly punctate, 

 eyes separated by a distance greater than the diameter of one eye, 

 antennae short, not reaching base of prothorax, apical joints en- 

 larged, two penultimate joints about as wide as long, eleventh 

 elongate-ovate. FrothorcLC 2 x '6b mm., deeply bisinuate and 

 and emarginate at apex, the middle lobe a little raised and ad- 

 vanced (this emphasised by the depression behind) ; anterior angles 

 strongly advanced in front of eyes, acute but a little blunted at 

 apex, sides nearly straight and gradually widened to apex, base 

 bisinuate; posterior angles acute, a narrow horizontal margin 

 within the raised border, widened at the angles; disc very finely 

 and densely punctate, with two small basal foveae and a large cen- 

 tral depression on apical half. Scutellum triangular with rounded 

 sides, punctate. Elytra of same width as prothorax at base and
