elytra are entirely black, except for a small, isosceles, flavous 

 triangle on each side of base. On the other the elytra are 

 flavous, except for a vitta on each side (invisible from above), 

 the suture and a curved mark attached to same near base ; 

 it appears also to have rows of very large punctures distinct 

 to apex, but posteriorly this is due to waterlogging ; from 

 certain directions the punctures, as impressed points, are seen 

 to be almost or quite absent, exax^tly as on the darker specimen. 

 A specimen from Adelaide River (in the British Museum) 

 has the elytra red, except for a narrow black sutural vitta. 



Rhyparida halticoides, n. sp. 



Black, upper-surface with a coppery gloss ; appendages, 

 labrum, and sometimes the throat and tip of abdomen, red. 



B end with rather dense and sharply-impressed punctures 

 of moderate size, becoming larger and more crowded on 

 clypeus ; with a narrow medio-frontal impression, touching the 

 very feeble clypeal suture. Eyes large, prominent, and widely 

 separated. Prothorax across middle more than twice the 

 median length, sides strongly rounded, front angles almost 

 unarmed ; with dense and not very small, sharply-defined 

 punctures. Elytra parallel-sided to beyond the middle, dis- 

 tinctly but not much wider than prothorax ; with rows of large 

 punctures, suddenly becoming much smaller, some rows com- 

 pletely absent from apical slope : interstices with sparse and 

 very minute punctures. Flanks of 'prosternum with dense 

 and rather coarse punctures, in places becoming longitudinally 

 confluent. Femora minutely dentate; claws each with a stout 

 basal appendix. Length, 3J-4^ mm.

 Type, I. 3399. 



In general appearance, at first glance, strikingly like many 

 species of Arsipoda of the Halticidea. 



Two specimens from the Blue Mountains (E. W. Ferguson) 

 possibly belong to this species, but they are rather more convex 

 and have the punctures on the flanks of the prosternum much 

 less numerous (quite absent from some parts), the prothorax 

 with the punctures smaller and with the sides rather angularly 

 dilated in the middle. In the table they would be placed with 

 the dark variety of dim/idiafa, but they are much smaller than
