Leugtli 2\ mm. 



Hab. S.E. Borneo {German Mission, ex coll. Fry). 



One male. Very like the Philippine L. dentatithorax and 

 L. siibdentatus ; the head ( cj ) testaceous in front, sub- 

 angulate at the sides before the eyes, and then obliquely 

 narrowed to the apex ; the second anteunal joint diti'erently 

 shaped; the prothoracic tooth smaller than in L. dentati- 

 thorax. 



The somewliat similarly-maculate L. quadriguttatus, Er., 

 has the sides of the protliorax unarmed. 



29 (f/). Laius semperi^ sp. n. 



Elongate, narrow, widened posteriorly, rather convex, 

 subopaque, finely pubescent ; black, the antennse (except 

 the four or five outer joints and the basal one in part) testa- 

 ceous, the elytra each with two large, transverse, somewliat 

 rounded, whitish spots on the disc (one below the base, the 

 other towards the ajjcx), the legs (the tarsi in part excepted) 

 piceous ; the entire surface densely, finely, rugulosely punc- 

 tate. Head rather convex anteriorly, obsoletely canaliculate ; 

 antennee long, joint 1 curved, thickened towards the apex, 

 2 elongate, subcylindrical, stout, 3-10 gradually tapering, 

 each longer than broad. Protliorax convex, longer than 

 broad, transversely depressed before the base, the sides with 

 a prominent median tooth. Elytra long, widest near the 

 apex. Legs rather short. 



S. Antennae (fig. 11) with joint 1 as in ?, 2 oblique, 

 moderately elongate, concave, scaphiform, toothed at the 

 inner basal angle, 3-10 longer and more slender than in ? ; 

 anterior tarsi simple. 



Length 3 mm. 



Hab. Philippines, Luzon {Semper, ex coll. Fry). 



One pair, the ^ immature. This is one of three closely 

 allied Philippine forms with the sides of the protliorax more 

 or less distinctly unidentate ; it is separable from the two 

 others by the narrower, oblique, scaphiform, second anteunal 

 joint in the J" (not unlike that of the same sex of the Bor- 

 neau L. tetrasiictus), and the smaller eiytral spots. 



29 (e). Laius subdentatus, sp. n. 



cJ . Elongate, narrow, rather convex, widened posteriorly, 

 finely pubescent, opaque ; black, the antennal joints 1-4 

 testaceous, the elytra each with two large, transverse, 

 yellowish-white or tlavescent spots — one ante-median, the
