that extends right across the elytra; the dark dorsal areas 
densely clothed with curled black scales, except at the apex 
where there are sparse, pale buff, setiform scales; the basal 
third of the lateral area, including the shoulders, quite bare 
and shiny; the lower surface fairly closely covered with 
pale buff plumose scales, except on the sides of the meta- 
sternum, which are very densely clothed with a silky patch 
of silvery-white hairs. 
Head with confluent punctation and a shallow median 
fovea ; a short median carina about the fovea in the ¢ only. 
Rostrum very long, longer than the head and prothorax, of 
equal length in the two sexes, and gently curved; in the g 
the dorsum markedly flattened from the base to the an- 
tenn, with a sharp median carina terminating at an inter- 
antennal fovea, an undulating lateral carina at the edge of 
the flattened area, and a less distmct one just within, the 
apical area convex and closely punctate, and the submentum 
with a downwardly projecting tooth; in the ? not flat- 
tened above, with confluent punctation in the basal half, 
a broad, low, smooth, median carina and a very narrow lateral 
one on each side, the apical area sparsely punctate and shiny. 
Antenne inserted at the middle of the rostrum in the @ and 
a little beyond it in the ¢; the scape as long as the funicle ; 
joint 1 of the funicle as long as 2+3, 4 to 6 bead-like and 
slightly transverse, 7 as long as the two basal joints of the 
club. Prothorax broader than long, parallel-sided from the 
base to the middle, then rapidly narrowing to the apex and 
with a shallow subapical constriction; the apical margin 
truncate dorsally, the dorsal outline slightly convex, the 
whole prothorax being tilted upwards auteriorly in relation 
to the long axis of the body ; the dorsum throughout with 
separated and much flattened granules, except the apical 
area, which is closely and shallowly punctate. Scutedlum 
small, not enclosed in front, pyriform, broadest behind, bare 
and usually with a shallow median impression. Elytra 
cylindrical, not broader than the thorax, with a broad, shal- 
low, transverse impression at the base, and broadly rounded 
behind; the striz shallow and with coarse punctures 
(mainly hidden by the scaling), but becoming much deeper 
and with much reduced punctures on the declivity; the 
intervals even, rugosely punctate, 4 and 5 being subgranu- 
late towards the base. Legs (fig. 1, g) elongate, shallowly 
punctate, and rather thinly clothed with linear scales ; the 
front femora with a broad triangular tooth, the front edge 
of which is obscurely denticulate, the teeth on the two 
posterior pairs progressively smaller; the front tibie very
