otlier subapical, neither quite reaching the suture or outer 

 margin ; the entire surface densely, minutely, rugulosely 

 punctate. Head triangular, finely canaliculate, the epistoma 

 simple, the eyes prominent ; antennae (fig. 4) long, joint 1 

 triangularly dilated outwards, 2 enormously thickened, 

 elongate-oval as seen from above, hollowed at the base and 

 apex, bidentate within, 3-10 elongate. Prothorax elongate, 

 feebly unidentate at the sides. Elytra moderately long. 

 Legs short ; anterior tarsi simple. 



? . Antennse short, tapering outwards, joint 2 elongate, 

 thickened, cylindrical. 



Length 24-3 mm. (S 2 ■) 



Hab. Philippines, Butuan, Davao, and Kolambugan, in 

 Mindanao {Baker: $ ? : Nos. 6699, 16155, 16156), Bohol, 

 Luzon {Semper: c? ? ). 



Four cT c? J fi^'e ? ? . This species works out as near 

 L. diversenotatus, from Banguey, in Pic's table (1910) of 

 the opaque forms with two white spots on each elytron. 

 There are numerous similarly-coloured Malayan insects, 

 most of which are probably peculiar to a particular island. 



29 (/). Laius subcarinatus, sp. u. 



? . Extremely like L. subdentatus, diflfering as follow^s : 

 head with a fine median carina, the eyes less prominent; 

 antennse a little more slender, joints 1-3 only in part testa- 

 ceous ; prothorax less narrowed posteriorly, the lateral tooth 

 just traceable ; elytra more convex, and more widened 

 posteriorly, the spots yellowish or white, the post-basal one 

 strongly transverse, the subapical one large, rounded. 



Length 2|-3|^f) mm. 



Hab. Palawan I. {Baker : type) ; Tenasserim, Tavoy 

 (Doherty). 



Three ? ? , one sent under the same number as a ? 

 L. subdentatus. This is one of three forms from Palawan 

 found by Mr. Baker, It cannot be referred to either of the 

 two species from that island named by Pic in 1910. The 

 allied L. inarmatus, Pic (1917), and L. carinaticeps , Pic 

 (1910), both from Java and both described from c? c? , are 

 said to have the head carinate, but the carina in the latter 

 is laterid. The Tenasserim examples (two ? ? ) have the 

 spots smaller and wholly white. The Sumatran L. luteo- 

 notatus, Pic (1921), must be an allied form. 



29 {g). Laius tetrops, sp. n.
