478 PERCY SLADEN TRUST EXPEDITION 
Length 14 mm. (¢ ?). 
Loc. Seychelles: Silhouette. 
One specimen, found at Mare aux Cochons on Sept. 6th, 1908. Recognizable by its 
comparatively long rostrum, prominent eyes, feebly constricted, rather coarsely punctured 
prothorax, and confusedly seriato-punctate elytra, and also by the fine erect pilosity of the 
upper surface. The under surface has not been examined, for fear of damage to the 
vestiture. Lasiotrupis clavigera is similarly pilose. 
LASIOTRUPIS, n. gen. 
Rostrum subcylindrical, curved, the antenne inserted towards the apex in ¢ and at 
a little beyond the middle in 9, the scrobes inferior and extending backward to between 
the eyes, the latter lateral, in part visible from above, the head feebly constricted immedi- 
ately behind them ; antennze long, slender, the funiculus 5-jointed, the club large, ovate, 
annulate; prothorax subquadrate; scutellum minute; elytra wider than the prothorax, 
narrowing from near the base, moderately long, punctato-sulcate ; anterior coxze small, 
separated by about their own width; intermediate and posterior rather widely separated ; 
metasternum moderately long; ventral segments 1 and 2 long, connate, 3 and 4 very 
short ; legs short, slender; tibize without visible uncus at the apex ; tarsi short, slender, 
joint 3 simple, not wider than 2, the claw-joint rather stout, the claws divergent ; body 
subfusiform, shining, sparsely pilose: species minute. 
Type, L. clavigera. 
The minute insect from which the above diagnosis has been drawn up has the general 
facies of a Stenomimus or Tytthomimus; but the funiculus is 5- (not 7-) jointed ; the 
antenne are long and slender, with an unusually large club; the tibie (as in Micro- 
himatium) are apparently unarmed at the apex; and the third tarsal joint is simple. 
The absence of ventral depression or fovea in the male is an unusual character amongst the 
Cossonids. The hairs on the upper surface are not easily seen, except on the elytra, 
and easily abraded. The specimens with somewhat gibbous rostrum and the antennze 
inserted towards the tip are assumed to be males. 
107. Lasiotrupis clavigera, n. sp. 
Moderately elongate, feebly convex, shining ; ferruginous or obscure ferruginous, the 
eyes black ; sparsely clothed above and beneath with rather long, fine, stiff, pallid hairs, 
those on the elytra setiform and arising from the punctures of the strize. Rostrum (9) 
shorter than the prothorax, depressed at the base and somewhat gibbous between the 
points of insertion of the antennz, sparsely, faintly punctulate, the short apical portion 
a little wider than the rest, (?) a little longer, simply curved, and with the apical portion 
relatively more elongate ; antennze with jomts 3—5 of the funiculus transverse, the club 
nearly as long as the funiculus. Prothorax subquadrate, about as long as broad, abruptly 
narrowed just before the feeble apical constriction; closely, rather coarsely punctate. 
Elytra considerably wider than the prothorax, parallel at the base, narrowing from about 
the basal fourth ; punctato-sulcate, the interstices narrow, convex. Beneath alutaceous,
