entirely concealed (except at sides) : an impunctate and 
slightly depressed median line. Elytra cordate, shoulders 
slightly prominent ; seriate-punctate, punctures large and 
deep ; interstices feebly convex, not at all or very slightly 
wider than punctures, themselves with small and rather 
numerous, but entirely concealed, punctures. Abdomen 
with punctures entirely concealed, but evidently dense and 
not very large. Terminal hook of posterior tihiie. strongly 
incurved and outwardly dentate. Length, 7 ; rostrum, 1^ : 
width, 4 (vix.) ; variation in length, 6^-7^ mm. 
Female. Differs in being entirely without golden ha"»r 
on the under surface, the terminal hook of the posterior tibiae 
simple, the rostrum squamose only at base, and antennae in- 
serted more distant from apex of rostrum.

A much less convex species than usual, the male witli 
very remarkable clothing and posterior tibiae. I believe the 
species belongs to DeciJaus, the clothing of the under surface 
is almost exactly the same as in aiiricomus, an undoubted 
Decila.us. . Many of the elytral punctures have a slightly tri- 
angular appearance, others are more or less rounded or 
ovate, each is isolated by a distinct transverse ridge, which is 
just below the level of the interstice, but which is more or less 
concealed by the clothing. 
Decilaus spissus, n. sp. 
Very densely clothed with soft, pale, dirty, fawn-coloured 
scales, which are larger and more rounded on prothorax and 
abdomen than elsewhere. Head and rostrum very densely 
clothed ; pectoral canal with a few elongate scales. 
Punctures of head and rostrum entirely concealed, but 
those on the latter evidently seriate in arrangement. Ros- 
trum wider at base than apex, and much wider than be- 
tween antennae. Scape stout, inserted nearer base than apex, 
the length of two following joints ; these subequal in length. 
Prothorax rather strongly transverse, sides not suddenly 
narrowed towards apex ; with dense, large, round, clearly- 
cut punctures, which are partially concealed. Elytra oblong- 
cordate, more than twice the length of prothorax-, striate- 
punctate, punctures rather large, subcontiguous : interstices 
convex, much wider than punctures, fourth widest of all. 
Two basal segments of abdomen with exactly similar punc- 
tures to those on prothorax. Length, 5 ; rostrum, 1§ ; widtli, 
2^ mm. 
The clothing is so dense that, except where abraded, the 
sculpture can scarcely be seen.
