towards the apex, oblique; the surface very densely, finely 
punctate. Head triangular, canaliculate above; eyes 
moderately large, prominent; antennz with joint 1 curved, 
much widened outwards, 2 extremely large, ear-shaped, 
simply concave within, and angularly produced at the 
proximal inner angle, which is furnished with a long, slender, 
curled appendage (P1. VIII. fig. 19), 3-9 rather long, slender, 
filiform. Prothorax transverse, subcordate, as wide as the 
head, deeply, transversely excavate before the base. Elytra 
rather short, dilated and rounded at the sides posteriorly. 
Legs short, tarsi less than half the length of the tibiz. 
Length 24 mm. 
Hab. Borneo, Brunei (éype of Pic: 3), Sarawak (A. R. 
Wallace, in Mus. Oxon.: 2). 
In the Hope Museum there is a specimen from Sarawak 
that is perhaps referable to L. borneensis, Pic, the ¢ of 
‘which is diagnosed in a few words only ina table of Malayan 
forms with 4-spotted elytra, the only tangible characters given 
being the monstrous second antennal joint (third of Pic) 
without ‘‘ fossette nette ” towards the apex and the testaceous 
anterior portion of the head. The head is much smaller 
than in L. guttatus, Pasc., and the antennal joints 3-10 are 
quite slender, 
28. Laius sarawakensis, sp. u. 
g. Oblong, narrow, widened posteriorly, opaque, very 
finely pubescent ; black, the elytra each with two whitish 
spots—one, large, transverse, below the basé, not reaching 
the suture or outer margin, the other smaller, rounded, on 
the outer part of the disc towards the apex,—the sides of the 
metasternum, the anterior knees, the tarsi and abdomen in 
part, and the antenne (the black apical joint excepted) testa- 
ceous ; the upper surface densely, very finely, the under sur- 
face more sparsely, punctured, the head and prothorax slightly 
shining when the pubescence is removed. Head subtri- 
angular, with a short longitudinal impression in the middle 
between the eyes, the latter moderately large, prominent ; 
apical joint of maxillary palpi rather broad ; antennz long, 
comparatively stout, joimt 1 much thickened, feebly curved, 
somewhat oval, slender at the base, 2 very broad and stout, 
oblong-oval, somewhat ear-shaped, excavate above, and with 
a long, straight, compressed appendage arising from near 
the base (Pl. VIII. fig. 20), 3 short, 4—9 a little longer than 
broad, 10 oval, stouter than and nearly twice as long as 9. 
Prothorax rather narrow, as long as broad, convex, sinuously
