portion with moderately large and rather dense punctures, 

 small elsewhere. Club rather long. Prothorax decidedly 

 transverse, sides moderately rounded, base strongly bisinuate ; 

 with moderately dense but comparatively small punctures^ 

 becoming very small at apex; median carina entirely absents 

 Elytra not much wider than prothorax, almost parallel-sided 

 to near apex; with rows of large deep punctures, becoming 

 smaller posteriorly, in feeble striae near base, but striae more 

 distinct posteriorly; alternate interstices elevated, the third- 

 very strongly so, and with transverse granules on basal fourth. 

 Metasternum rather feebly ridged on each side between coxae^ 

 episterna each with a continuous row of punctures. Abdomen 

 with basal segment flattened in middle, third and fourth with 

 rather dense setiferous punctures, not in rows. Legs stout; 

 femora rather strongly dentate; tibiae compressed, somewhat 

 curved, rather narrowed to apex, punctures very small and 

 not in conspicuous striae. Length, 6 mm. 



9 . Differs in having rostrum somewhat longer and 

 thinner (especially towards apex), shining, with smaller and 

 sparser punctures; antennas inserted not quite so close to^ 

 apex of rostrum, and basal segment of abdomen moderately 

 convex.

At first sight apparently belonging to Perissops, but the 

 eyes are coarsely faceted and abdominal sutures straight. This 

 and several other species of the genus with alternate inter- 

 stices conspicuously elevated look as if they might belong to 

 Ccelosternus, but their femora are unidentate. The metallic 

 clothing is almost unique in the Australian members of the 

 subfamily. On the prothorax the clothing varies from thin 

 setae to fairly stout scales, and in colour from white to sooty, 

 the pale scales (some of which have a purplish lustre) are more 

 or less condensed into three feeble longitudinal stripes, on 

 each side in front there is a small spot of white scales with 

 a golden lustre. On the elytra there are two very irregular 

 fasciae of pale scales, a feeble one at basal third, irregularly 

 traceable on to shoulders, and a wider one at summit of 

 posterior declivity; the pale scales from some directions 

 appear to be almost stramineous in colour, but they vary 

 from almost every point of view from red, to purple, aud 

 green, and golden-green. From some directions also some of 

 the interstices have a greenish lustre, this being due to minute 

 scales that, individually, are almost too small to be seen 

 under a lens. The under-surface and legs are clothed with 

 whitish setae. The prothoracic punctures (where not obscured 

 by clothing) look as if each had been punched in.
