channelled within, border, extreme border very narrow at sides, and 
not continued beyond the angles at apex ; disc and margins (like the 
head) closely, not finely, punctate, with some coarse verniiculate 
impressions on the centre and short medial line near apex. 
Scutellum triangular, longitudinally deeper and less transverse 
than usual. Elytra much wider than prothorax at base, and closely 
applied thereto, shoulders obsolete, sides widely oval, with greatest 
width behind middle, apical declivity steep, each elytron with three 
sharp slightly undulate costa?, besides the double sutural elevation, 
the last more strongly raised and bifurcate in the seutellary region, 
becoming interrupted and nodulose on hinder half ; the first costa 
extending from base to apical declivity, the second from base to 
beyond the first, the third starting from behind the shoulder at a 
junction with the second, reticulately and vaguely connected with 
second near apex ; a> lateral indefinite line of pustules on posterior 
half forming a fourth sub-co state impression ; intervals with vernii- 
culate transverse indefinite reticulation, with rows of large punc- 
tures on sides of costae, and a row of larger punctures at sides^ 
extreme border not raised or at all horizontal. Under surface 
black, moderately nitid, glabrous, and minutely shagreened, 
sternum closely punctate, prosternal process with raised margins, 
bluntly rounded at apex, intercoxal process wide, margined, the 
margin interrupted in middle; legs, especially hind femora, very 
long, tibia? without tomentose clothing.

Habitat : Yetholm, New South Wales (Mr. H. Deane, M.Inst.

A single specimen, taken by Mr. Deane, is very distinct from 
all described species, differing from the other cost ate species in its 
subangulate-sided head, its wide elytra (compared with prothorax), 
the thickened and reflexed margins of prothorax with its pronounced 
hind angles, and the coarse elytra! sculpturation, in which the 
reticulation is only well defined towards the apex.
