458 PERCY SLADEN TRUST EXPEDITION 
obscurely rufescent. Rostrum very stout, moderately long, coarsely punctate; head 
similarly punctured ; eyes small, transverse, depressed. Prothorax long, subcylindrical, 
deeply constricted beyond the middle; coarsely, closely punctate. Elytra comparatively 
short, wider than the prothorax, obliquely narrowed from about the basal third, and 
produced at the apex, the humeri oblique; coarsely punctate-striate, the interstices 
uniformly convex throughout, the fifth and seventh interstices not carinate at the apex. 
Length (exclud. rostr.) 14%—275 mm. 
Loc. Seychelles : Mahé. 
Twenty specimens, found in the same localities as the preceding species (and also 
in the Mare aux Cochons District), in company with which it was very possibly taken. 
Smaller than the smallest D. lymeaxylon, and separable from it by the non-carinate apices 
of the elytra. No sexual differences have been detected. 
Sect. Pentarthrides. 
CHG@RORRHINODES, nN. gen. 
Rostrum stout, curved, parallel-sided, about as long as the exposed portion of the 
head, the antennz inserted at the middle, the scrobes oblique and rapidly descending ; 
head long, exserted, the eyes small, lateral, somewhat prominent, distant from the 
prothorax ; antennze moderately long, the funiculus 5-jomted, joint 1 stout, 2—4 widening 
outwards, 2 small, triangular, 3—5 transverse, the club small, oval, annulate, pubescent ; 
prothorax subcylindrical, constricted before the apex; scutellum scarcely visible; elytra 
elongate, parallel-sided to beyond the middle, the apices simple; anterior coxze somewhat 
narrowly separated ; metasternum long, unimpressed ; ventral segments 1 and 2 connate, 
2 a little longer than 3 and 4 united, the latter short, the sutures straight ; legs short ; 
tibize with a slender uncus at the outer apical angle; tarsi with joints 1 and 2 very short, 
narrow, 3 wider, feebly lobed, the claws small; body very narrow, elongate-fusiform, 
opaque, rugose and incrustate above. 
Type, C. tenuiculus. 
The type of this genus may be described as a very narrow, small, feebly-developed 
Cherorrhinus (= Pentacoptus, Woll.), with a strongly exserted head, a curved, moderately 
long, stout, subeylindrical rostrum, rather long antennze, and the stout, spiniform 
prolongation of the outer angle of the tibiee reduced to a slender uncus. The general 
facies is suggestive of that of Melarhinus. The type of Cherorrhinus is European, that 
of Pentacoptus is from Japan. The 5-jointed funiculus separates the present genus 
from Pholidoforus. C. tenwculus is probably winged. 
79. Cherorrhinodes tenwculus, n. sp. 
g. Very elongate, narrow, fusiform, feebly convex, opaque ; piceous, the antennee 
and legs obscure ferruginous, the dense rugose punctuation of the upper surface visible 
through the earthy inerustation. Rostrum stout, less rugosely punctured than the 
exposed portion of the head, the two together much longer than the prothorax, the 
head narrow, less than twice the width of the rostrum. Prothorax about as long as
