[December 
but not strongly rounded in much of length, weakly sinuate before 
base; basal angles c. right or slightly obtuse, scarcely blunted; apex 
subtruncate or very broadly emarginate with angles scarcely advanced, 
apex not margined ; base subtruncate or slightly emarginate at middle, 
slightly rounded-oblique toward sides, weakly margined only toward 
angles; lateral margins narrow, scarcely wider basally, each with i 
seta about 1/4 from apex and 1 on margin at basal angle; disc con- 
vex, middle line well impressed, transverse impressions rather weak; 
baso-lateral foveae rather weak and irregular, reaching posterior 
margin but separated from side margins by convex areas, not punctate 
and not much more rugulose than disc. Elytra slightly more than 1 /4 
wider than prothorax, rather short, slightly narrowed anteriorly; hu- 
meral angles nearly right, slightly toothed; striae represented by de- 
pressed spaces between intervals; latter subequal on disc, convex but 
not much elevated except 7th elevated and costate basally; 10th inter- 
val indicated posteriorly; each 3rd interval with 2 or 3 dorsal punc- 
tures posteriorly. Mesosternum anteriorly and prosternal process 
(sometimes inconspicuously) setose. Male front tarsi moderately 
dilated, 3 segments squamulose; c? with 1, $ 2 setae each side apex 
last ventral segment. Length 18-20; width 6. 5-7.0 mm. 
Holotype <$ (M.C. Z. Type No. 30,359) and 4 paratypes from 
Mt. Fisher (see below), c. 4000 ft., Feb. 1958; and 5 additional para- 
types from mountains above (SW of) Millaa Millaa, c. 3500 ft., 
Dec. 1957 ; all specimens taken by the Darlingtons, in rain forest. The 
two localities are close together in the mountain mass between Raven- 
shoe and Millaa Millaa on the Atherton Tableland, North Queens- 
land. 
This species differs from the preceding one (f rater) in smaller size, 
color, smoother basal pronotal foveae, and other details. It differs 
from soror in form of c? tarsi, in being a little broader, different in 
color, and in other details. For further comments, see under following 
species. 
Trichosternus fisheri new species 
Larger than preceding; black with strong purplish reflections, mod- 
erately shining except elytra slightly duller. Head slightly more than 
4/5 width prothorax; eyes moderate, genae c. wide as eyes, rounded 
and narrowed to neck; antennae rather long (in genus), passing base 
of prothorax by 2 or 3 segments; 2 supra-ocular setae each side. Pro- 
thorax subcordate, c. 1/4 or less wider than long at middle; base c. 
1/10 narrower than apex; apex subtruncate or very broadly emargin- 
ate, with angles scarcely advanced; apex not distinctly margined; base
