98 
broadly arcuate anteriorly, straight or even faintly sinuate 
and only slightly converging posteriorly; basal angles al- 
most idght but narrowly rounded ; base broadly sinuate ; 
apex subtruncate or very broadly emarginate, with ant- 
erior angles not advanced; lateral margins very narrow, 
with usual setae at base and about 1/4 from apex; disc 
normally convex; sub-basal impressions short, deep, linear, 
iri*egular or subpunctate; a group of punctures (sometimes 
only 1 puncture) between sub-basal impression and lateral 
margin; disc otherwise impunctate, with median line light, 
transverse impressions vague; base not distinctly mar- 
gined, apex margined at sides but not at middle. Elytra 
about 1 6 wider than prothorax; sides subparallel, slightly 
sinuate before apex, then conjointly rounded; basal margin 
entire, bent forward and forming acute angles (more acute 
titan in }tiger) at humeri; striae entire, deep, impunctate; 
intervals slightly convex on disc, more so laterally and 
apically; dorsal intervals equal, 3rd impunctate; 6th in- 
terval a little narrower especially at extremities; 7th still 
narrower and abbreviated posteriorly (ending near apical 
14); 8th very narrow and a little more abbreviated (but 
not so short as in niger) ; 9th with usual ocellate setigerous 
punctures; a vague 10th interval present but not sharply 
sei>arated from marginal trough. Prosternal process strong- 
ly margined (not so in niger), without setae; metepisterna 
short, they and sides of anterior ventral segments more or 
less punctate, but body below almost impunctate; last 3 
ventral segments deeply transversely sulcate basally. Male 
with anterior tarsi moderately dilated, first 3 segments 
biseriately squamulose; last ventral segment of both sexes 
with 1 conspicuous puncture (sometimes doubled) each 
side of middle. Length 6-7 ; width 2.4-2.S mm. 
Holotype $ (M. C. Z. Type No. 29,015) and 10 para- 
types all from National Park, McPherson Range, South 
Queensland (on New South Wales border), 3,000-4,000 
ft. altitude, March, 1932. 
In appearance this new species is a diminutive of Setalis 
nigtr Cast., but the size difference is great {niger is 10-12 
mm. long), and there are some definite structural differ- 
ences ; the new species has more acute humeri, less abbrevi- 
ated eighth elytral intervals, and a strongly margined pro-
