Trichosternus setosiceps SI. 
Sloane (1923, p. 23) described setosiceps from the South Johnstone 
River and Malanda, which are on or near the Atherton Tableland. 
The species is widely distributed on the Tableland, except apparently 
the northern part, and reaches the lower slopes of Mt. Bellenden Ker 
and extends south to the Kirrama Range. 
This species differs from all other Trichosternus in having 2 seg- 
ments of each male front tarsus squamulose. 
Trichosternus kirrama new species 
Form as figured (Fig. 3), large, with strongly cordate prothorax 
and oval elytra; black, head and prothorax moderately shining, elytra 
dull. Head large, 4/5 or slightly more width prothorax; eyes small, 
genae slightly wider than eyes, broadly rounded and narrowed pos- 
teriorly to neck; antennae rather long, passing base of prothorax by 
c. 2 segments; 2 or 3 supra-ocular setae each side (often asymmetri- 
cal) ; frontal foveae as usual except area between them slightly de- 
pressed and/or with longitudinal prominences outside them. Prothor- 
ax strongly cordate, nearly 1/2 wider than long at middle; base c. 
4/5 (±) width of apex; apex emarginate at middle, rounded toward 
sides, with angles (lateral channels) advanced; apex not margined; 
base broadly emarginate except subtruncate near angles, rather irregu- 
lar, vaguely margined ; sides rounded through much of length, strongly 
sinuate about 1/6 before base, thence subparallel to c. right, well de- 
fined posterior angles; lateral margins moderate anteriorly, slightly 
wider posteriorly, each 2 to 4 (rarely 5) setae at and before middle 
and one a little before base; disc with usual middle line, transverse 
impressions weak ; baso-lateral impressions irregular, transversely strig- 
ulose, the strigulose area extending forward at sides and across base; 
extreme basal strigae longitudinal. Elytra 1/5 or slightly more wider 
than prothorax; margin somewhat obtusely angulate but only vaguely 
toothed at humeri ; striae formed by lines of small punctures ; even 
intervals slightly convex, odd intervals 3 and 5 slightly more raised 
but not costate, interval 7 strongly raised, costate at base; no 10th 
interval; each 3rd interval 2-punctate, behind middle and on declivity. 
Mesosternum and prosternal process not setose. Male front tarsi 
moderately dilated, 3 segments squamulose; 2 or 3 (often asymmetri- 
cal) setae each side last ventral segment in both sexes. Length 30-33; 
width 9.9-10.6 mm. 
Holotype cf (M.C. Z. Type No. 30,364) and 11 paratypes all 
from Kirrama Range, near Cardwell, North Queensland, 2000-3000 
ft., Dec. 1957 and Feb. 1958, taken by the Darlingtons, in rain forest.
