342 Mr. G. C. Champion on various African 
narrowed posteriorly, transversely, arcuately depressed 
before the base. Elytra moderately long. Metasternum 
convex in the middle. Legs rather stout, short, the posterior 
tarsi barely half the length of the tibiz. Wings ample. 
Length 2} mm. 
Hab. Borneo, Mt. Matang, W. Sarawak, alt. 1000 ft. 
(G. E. Bryant: 17.1.1914). 
One male. Very near L. 4-guttatus, Er., the type, g, of 
which was found on the Island of Bintang, in the Gulf of 
Singapore, before 1840. _ The comparatively stout, testaceous 
antenna, with joint 10 only black, and 2 strongly appendi- 
culate, and the wholly black head, sufficiently distinguish the 
present insect. It cannot be identified with any of the 
numerous Malayan species of the Jntybia-group of Laius 
tabulated by Pic (‘ L’Echange,’ xxvi. pp. 83, 84, 1910). 
29. Laius tetrastictus, sp. n. 
9. Extremely like ZL. sarawakensis, but differing as 
follows: the two white or yellowish-white spots on each 
elytron shaped thus—one, near the suture below the base, 
large, narrowing outwards, the other transverse, large, on 
the disc towards the apex ; head sharply canaliculate down 
the middle, the groove extending upwards on to the vertex ; 
eyes a little larger; apical joint of maxillary palpi not so 
stout ; antenne more slender, gradually tapering outwards, 
joints 2-5 in great part testaceous, 2 very stout, flattened- 
subcylindric (oblong-oval as seen in certain aspects), nearly 
as long as 3-5 united; legs black. 
?. Var. The subapical transverse spot reduced to a small 
streak. 
Length 23-3 mm. 
Hab. Borneo (ex coll. Sharp: var.), Quopin W. Sarawak 
(G. E. Bryant : 15.11. and 19. ii. 1914). 
Two specimens from Quop, precisely similar, and one of 
variety. It is scarcely possible that these insects are females 
of L. sarawakensis, the sharply canaliculate head and the 
relatively larger eyes forbidding such an association. The 
antenne are shaped almost as in L. guttatus (9), as figured 
by Pascoe. 
30. Laius carinatifrons. 
Laius carinatifrons, Pic, Bull. Soc. Ent. Fr. 1910, p. 290 (¢ 2). 
3. Head depressed in the middle, transversely carinate
