orbital punctures. Prothorax widely transverse (5 x 8) ; a trifle 
wider than the elytra ; rounded on the sides, widest at about half 
its length, and narrower in front than at the posterior angles; 
lateral margins wide and reflexed ; base lobate, the basal part 
defined by a transvei’se line, a distinct transverse line in front ; 
the median line distinct, ending in front and behind in the 
transverse lines ; an oblique impression near the lateral angles of 
the base ; each lateral channel with three punctures. Elytra of a 
somewhat oval form (7f x 11), the sides widest at the middle of the 
length, and narrowing equally towards base and apex ; the base 
truncate and declivous ; the lateral margins reflexed, wider 
towards the apex, at the humeral angles slightly thickened and 
erect ; the suture rather deeply impressed ; two discoidal punc- 
tures towards the apex. The anterior . tibiae tridentate as in C. 
OdevKihnii. 
Loc . — Gascoigne River, West Australia. 
I am indebted to Mr. C. Fi’ench of the Botanic Museum, 
Melbourne, for this handsome species. 
Chariscapterus, subgen.nov. 
Caput magnum, supra oculos unipunctatum ; frons bisulcata, 
sulcis parallelis. 
Palpi maxillares ordinarii, apice dilatati truncati ; lahiales 
securiformes. 
Antennae sub-moniliformes. 
Prothorax valde transversus, late marginatus. 
Elytra late marginata, postice bipunctata. 
an^tcfe valde tridentata; ; femora antica ad apicem intus 
punctata. 
This subgenus will come between Calliscapterus (as represented 
by C. campesti-is, C. Odewaknii^ ikc.) and PLatythorax. 'The 
anterior tibite are much more strongly tridentate than in 
Calliscapterue caTnpeetrie, being very like those of Platyt/iora.c
