of new genera and species of Tenebrionidce. 359 
joints 9 — 10 of tlie antennre are fully as long — if not 
longer — as broad ; neither does it any better accord with 
Erichson's genus Olisthcena. 
Mithippia Jansoni, n. sp. 
This species differs from Pascoe's aurita (Ann. Mag. 
Nat. Hist. 1869, p. 293) in having the elytra covered 
with rounded punctures — more or less confluent by irre- 
gular transverse wrinkles — without the slightest trace of a 
regular linear arrangement, and by being entirely destitute 
of hairs. 
Long. 4 lin. ; lat. elytr. 1^ lin. 
Hab. — Albany and Champion Bay, West Australia. 
Five examples. 
Ctimene, n. g. 
Mentum trapezoidal, very convex in the middle, nar- 
rowly flattened at each side ; labium broadly emarginate 
in front, last joint of its -palpi oval, broadly truncate at 
apex, that of the maxillaries rather strongly securiform : 
head immersed in prothorax up to the eyes, broadly rounded 
in front : antennary orbits rather long and narrow, obliquely 
rounded at the sides, a little reflexed : epistomal suture 
strongly marked : eyes moderate, transverse, reniform, dis- 
tant, the portion visible above rounded: antennce moderate 
in length, pilose, much stouter outwardly from the 6th 
joint; 3 as long as 4 — 5 together ; 7 — 10 obconic, gradually 
wider ; 9 — 10 a little wider than long; 11 large, rounded 
at apex : prothorax transverse, moderately and regularly 
convex, arcuate-em arginate in front, front angles not at all 
prominent ; sides finely margined, slightly and curvedly 
narrowed from base to apex; base broadly lobed in the 
middle, and subtruncate in front of the scutellum : scutel- 
lum rather large, triangular : elytra elongate, subcylindric, 
the greatest convexity behind the middle, broader at base 
than base of prothorax ; sides strongly margined, reflexed 
and canaliculate ; epipleural fold somewhat abruptly termi- 
nated at the 4th ventral suture : p)rosternum a little pro- 
duced in front, compressed but not carinate, the process 
horizontal, produced and triangulate behind, the end 
slightly upturned : mesa sternum rather short, vertical in 
fi'ont, and triangularly cleft nearly to the base : inter coxal 
process somewhat narrowly oval : legs short ; femora 
thickened ; tibiae a little thickened outwardly ; tarsi pilose 
beneath, first joint of the posterior longer than the two fol-
