distinguished by the tips of the elytra (pi. xxv., figs. 23 and 

 25), these not being notched on the present one. Black males 

 may be distinguished from males of atra, by the inconspicuous 

 punctures of the upper-surface. From the real pi/silla, of 

 Blanchard, it is distinguished by. its larger size; the outlines 

 of the female elytra are somewhat similar, but the longer front 

 portion of the front tarsi of the male is considerably longer 

 and otherwise different. So far as the specimens before me 

 indicate, however, the present species is confined to Queens- 

 land, and the others mentioned to New South Wales and 

 Victoria. On fig. 24 the apical portion of the larger front claw 

 of the male is shown as long and thin, as it appears from one 

 direction, but from another it is seen to be strongly dilated to 

 its base ; and in fact the claw varies in appearance from every 

 point of view. •

$ . Colours variable. Prothorax, elytra, and parts of 

 under-surface opaque owing to a sericeous or pruinose bloom. 

 Prothorax and elytra with a few fringing setae. 



Sculpture as described in preceding species except that the 

 hind suture of the clypeus is better defined, that its suture 

 with the labrum is marked by a series of conspicuous punc- 

 tures, that the elytra are less distinctly separately rounded at 

 apex, and that the front claw- joint with its claws are somewhat 

 different. Length ( d , 9 ), 3'25-3'9 mm. 



9 . Differs in having the prothorax and elytra polished, 

 with more distinct punctures, the elytra wider and each side 

 near .apex with a flange-like elevation, the abdomen larger, 

 more convex, and the front claw-joint with its claws, much as 

 the others.

A small species with the sericeous appearance of the elytra 

 of the males very pronounced. The female may be distin- 

 guished from females of other species by the sides of the elytra, 

 each of these near the apex has a somewhat convex flange, 

 causing the apex to appear rather abrupt ; from some directions 

 and in certain lights each side appears to be notched (some- 

 what as on the females of ruficollis), but this is due to the 

 part at the apparent notch being very thin, allowing light to 

 show through. The average size of specimens is slightly more 

 than that of pusilla, and distinctly less than that of ruficollis. 

 On the male the fringe on each side cousists of a few r
