most of length (most strongly so near base) ; 10th interval indicated 
but not well developed; each 3rd interval with o, 1, or 2 dorsal punc- 
tures behind middle (often asymmetrical in number and position). 
Mesosternum anteriorly and prosternal process setose. Male front 
tarsi slightly dilated, 3 segments squamulose below; <A with 1, $ 2 
setae each side last ventral segment. Length 23.5-27; width 7.9-9. 1 
mm. 
Holotype cf (M. C. Z. Type No. 30,356) and 39 paratypes all 
from west slope Mt. Bartle Frere, North Queensland, 3000-5000 ft. 
(none lower), Dec. 1957, collected by the Darlingtons, in mountain 
rain forest. Also 6, not types, from east side Mt. Bellenden Ker, 
3000-4500 ft., Dec. 1957, taken by myself, in mountain rain forest. 
This seems to be a typical, rather generalized (primitive?) Trichos- 
ternus, without known close relatives. It is of course distinguished 
from other species in the preceding key. 
Trichosternus nudipes new species 
Form about average ; greenish black, the green most distinct at sides 
and baso-lateral areas of pronotum and marginal channels of elytra; 
head and pronotum shining, elytra duller. Head c. 3/4 (by measure- 
ment) width prothorax; eyes small but abrupt, genae c. wide as eyes, 
convex, somewhat narrowed to neck; antennae of moderate length; 2 
supra-ocular setae each side. Prothorax subcordate, moderately nar- 
rowed at base, c. 1/3 (±) wider than long at middle; base slightly 
(less than 1/10) wider than apex; apex broadly emarginate with 
angles (lateral channels) slightly advanced, not margined; base 
broadly emarginate at middle, slightly rounded laterally, margined 
laterally; sides broadly rounded for much of length, moderately sinu- 
ate near c. right or slightly obtuse, scarcely blunted basal angles ; later- 
al margins narrow, not wider basally, each with 1 or sometimes 2 
setae each side 1/3 or less from apex and 1 seta on margin at basal 
angle; disc not very convex, middle line fine, transverse impressions 
weak; baso-lateral impressions deep, c. 1/3 length prothorax, separated 
from lateral margins by convexities but extending inward somewhat 
vaguely nearly to middle; disc of pronotum impunctate except base 
irregularly rugulose. Elytra 1/3 or less wider than prothorax, sub- 
oval, slightly narrowed anteriorly ; margins forming c. right or slight- 
ly obtuse, finely raised-dentate angles at humeri; dorsal striae very- 
fine, finely punctate; each elytron with 7 (including suture) rather 
weak but almost entire costae, 7th carinate basally; 10th interval in- 
dicated toward apex; 3rd interval usually 2-punctate, the punctures 
at or before apical 1 /3 and near apex, but individual punctures some-
