sternal process. (The M. C. Z. possesses a good series of 
niger from several localities in northern New South Wales 
and southern Queensland.) The new species very much 
resembles certain Setalimorphus, especially S. regidcm's SI. 
(which we have), but differs in the unusual modification of 
the seventh and eighth elytral intervals. 
Genus Trichosternus Chd. 
Trichosternus relictus n. sp. 
Rather elongate in genus, subparallel, normally convex; 
piceous black with purplish reflections especially on head, 
pronotum, and elytral margins (sometimes brassy on head 
and pronotum) ; legs piceous; antennae with 3 basal seg- 
ments piceous, other segments pubescent and progressively 
paler brown; head and pronotum shining, with microsculp- 
ture fine and lightly impressed (nearly isodiametric on 
head, somewhat transverse on pronotum) ; elytra (except 
margins) duller, with microsculpture fine but deeply im- 
pressed, isodiametric; but marginal trough of elytra shin- 
ing, with microsculpture faint; whole insect virtually im- 
punctate above and below, except for punctures of fixed 
setae. Head large,- .77 and .85 width prothorax in • $ 
measured, but appearing wider; mandibles rather short; 
eyes small but convex, slightly more prominent than genae ; 
genae barely longer than eyes, convex in profile ; 2 setae 
above each eye; frontal impressions parallel, not deep, 
rather irregular; mentum deeply emarginate, with tooth 
rather broad, short, channeled ; labium bisetose ; paraglos- 
sae glabrous; inner lobe of maxilla strongly curved in at 
apex, with inner margin densely ciliate. Prothorax nearly 
1/3 (width/length 1.33 and 1.31 in <? 9 measured) wider 
than long, widest about 1/3 from apex; base slightly nar- 
rower than apex; sides only moderately arcuate anteriorly, 
slightly arcuate or straight or at most faintly sinuate post- 
eriorly; basal angles narrowly rounded, obtuse; base broad- 
ly and shallowly emarginate; apex scarcely emarginate, 
with anterior angles slightly advanced; lateral margins 
rather narrow anteriorly, a little wider posteriorly, each 
with a seta near (just before) base and at about apical 1/3; 
baso-lateral impressions irregularly rounded, each with 
whole bottom occupied by a low tubercle; disc normally
