and sparser puncturation, and in tlie shape of the head. In form 

 X. ceylonicum most closely approaches Tricliosiiliaeriestes fryi (infra), 

 the present insect having the 8th joint of the antennae not markedly 

 wider than the 7th, the setae less numerous, the colour different, etc. 



Lissodema denfiqernm, n. sp. 



Elongate oval, castaneous, with the club of the antennae and the apical 

 twd-tliirds of the elytra piceous. Rostrum short; siipra-antennal carinae 

 straight, convergent in front. Thorax trausverse, widest a little in front of 

 the middle ; sides each with five teeth, of which the first (anterior) is small 

 and blunt, the other four being very stout and almost equal in size, each tooth 

 hearing on its apex a straight seta ; disc evenly convex from side to side, 

 coarsely and rather closely punctate, with a transverse impression before the 

 base. Elytra widest behind the middle, sides rounded throughout ; shoulders 

 rounded, lateral carina completely visible from above; puncturation strong in 

 basal half, gradual!}' obsolescent towards the apex ; punctures in rows, not very 

 closely placed, becoming rather confused towards the base, especially in the 

 scutellar area. 



Length 2 mm. 

 Hah. Java {Boivring). 



A single ^eclmen. A stout, convex species, apparently most closely 

 allied to L. japouum lleitt. and L. miiuifum Lewis, both from Japan. 

 From the former it differs, inter alia, in its shorter antennae, the more 

 coarsely punctured prothorax, and the less regular, somewhat confused 

 puncturing of the elytra ; in L. japouum the rows of punctures are 

 impressed with slightly conyex intervals. From L. minutum the present 

 species is separable by the stronger lateral teeth of the prothorax, the 

 coarse, though not crowded jiuncturing of the disc, the confused elytral 

 puncturation, etc. 



Lissodema Irwisi, n. sp. 



Elongate oval, nitid, testaceous, with the elytra paler except for a darh 

 fasc'a across the middle which extends backwards along the suture, and a 

 (lark triangle at the base ; the latter is due, iu part at any rate, to the dark 

 abdomen, where it is not covered by the folded wings, showing through the 

 translucent elytra. Head ratlier sparsely punctate, the supra-antennal carinae 

 sinuate, so that the rostrum is wider at the apex than at the points of insertion 

 of the antennae ; tlie latter moderately slender, the basal joint not very strongly 

 inflated, joints 2-8 gradually decreasing in length, but all longer than wide, 

 the last three joints very strongly incrassate and much darker in colour. 

 Thorax transverse, widest before the middle, with five setigerous teeth, which 

 increase in size from in front backwards, on each side ; disc evenly convex 

 from side to side, strongly but not closely punctate, with a strong transverse 

 fovea or impression on each side before the base. Elytra oval, widest about
