Species of Wc'uhs from (he Oriental Rerjion. 403 



tliMt extends ri<i;lit aevoss the elytra ; the dark dorsal areas 

 densely clothed with eiirled hlueU scales, except at the a[)ex 

 where there are sparse, pale bull', setiform scales; the basal 

 third of" the lateral area, iucludiuj^ the shoulders, (juite bare 

 and shiny ; the lower surface fairly closely covered with 

 pale buff plumose scales, except on the sides of the meta- 

 stei'uuui, which are very densely clothed with a silky patch 

 of silvery-white hairs. 



Head with conllnent punctation and a shallow median 

 fovea ; a short median carina about the fovea in the J" only. 

 Rostrum very long, longer than the head and prothorax, of 

 equal length in the two sexes, and gently curved; in the cJ 

 the dorsum markedly flattened from the base to the an- 

 tenna), 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 distinct one just within, the 

 apieal area convex and closely punctate, and the subnientum 

 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. 

 Antenna 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 subapieal constriction; the apical margin 

 truncate dorsally, the dorsal outline slightly convex, the 

 whole prothorax being tilted upwards anteriorly 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 shallow ly punctate. Scutellum 

 small, not enclosed in front, pyri form, broadest behind, bare 

 and usually with a shallow median impression. Elytra 

 cylindrical, not broader than the thorax, with a broad, shal- 

 low, transverse iin[)ression at the 1jase, and broadly rounded 

 behind; the stride 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 j)unctate, 4 and 5 being subgranu- 

 late towards the base. Legs (fig. 1, g) elongate, shallowly 

 punctate, and rather thinly clothed Avith 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 tibife very
