and Asiatic Species of Laius. 329 
two basal joints of the antennz partly testaceous, the elytra 
nigro-cyaneous, with a rather broad, common, angulate, 
flavous or rufescent, submedian fascia; the head and 
prothorax very sparsely, minutely punctate, the latter 
almost smooth on the disc, the elytra with intermixed 
coarse and fine punctures. Head scarcely as wide as the 
prothorax, impressed in the middle between the eyes, the 
latter rather. prominent ; antenne with joints 1 and 2 
moderately thickened, long, subequal in length, 1 curved, 
3-9 longer than broad. Prothorax convex, broader than 
long, rounded at the sides, constricted posteriorly, deeply, 
transversely excavate before the base. LElytra rather 
elongate, broad, in the widest part about twice the breadth 
of the prothorax, bluntly rounded at the tip. 
6. Antennal joints 1 and 2 almost wholly, and the 
anterior femora in part, testaceous ; antennal joint 1 broadly 
widened, curved, triangular, 2 extremely large, concave, 
broadly lunate, rounded distally and bicuspid at the inner 
angle, each point bearing a small tuft of long curled hairs 
(Pl. VIII. fig. 7), 3-9 longer than broad. 
Length 4-42 mm. (¢ 2.) 
Hab. Invia, Ranikhet and Central Almora Divisions of 
Kumaon (H. G. C.: vi. 1920). 
Described from a series of thirty females and four males, 
some of which were found on a species of Polygonum. This 
species may be known by the almost smooth, shining, black 
head and prothorax, and the nigro-cyaneous, rufo- or flavo- 
fasciate elytra, the latter with intermixed coarse and fine 
punctures; the ¢ with an enormous, concave, luniform, 
bicuspid second joint to the antenne. L. fasciatus, Bourg. 
(1890), from Cambodia, is doubtless an allied form. 
9. Laius taprobanus, sp. n. 
?. Moderately elongate, rather convex, widened posteri- 
orly, shining, clothed with fine greyish pubescence intermixed 
with longer, erect, hairs; black, the antennal joints 1-3 
(1 sometimes with a dark line above), a common ante- 
median fascia on the elytra (widened outwards and also at 
the suture), and the ventral surface in part, testaceous or 
luteous, the rest of the elytra nigro-cyaneous. Head small, 
closely punctulate, sulcate in the middle between the eyes ; 
antennz moderately long, joints 1 and 2 elongate, rather 
stout, 2 a little shorter than 1, 4-11 much more slender, 
shorter, subfiliform, Prothorax very little wider than the 
head, about as long as broad, constricted behind; smooth
