congeneric with B.-apicalis, Motsch., the type of the genus, 
is: doubtful, because the author says of this species that the 
claws of the tarsi are simple. In the Ceylonese species of 
Biurus and in B, pennatus the claws are formed as in Ichthy- 
urus, that is, with two conspicuous inner processes. Harold 
catalogues the genus as Diurus.

Malthodes kobensis, sp. n. 
Niger, opacus ; capite thoraceque dense granulatis ; antennis nigris ; 
pedibus infuscatis. 
L. 5 mill. 
Black, opaque; the head and thorax densely sculptured, 
sculpture granulate, the former with prominent eyes and 
narrowed from the eyes to the neck; the thorax nearly quad- 
rate, anterior angles obtuse, posterior angles a little produced ; 
the elytra somewhat less opaque than the thorax, with sculp- 
ture also less remarkable, strie faintly visible; the legs, 
basal half of the thighs palish brown, the rest with the tibiz 
and tarsi infuscate.

Cyphonocerus marginatus, sp. n. 
C. ruficoll: similis, sed differt in colore ; thorace elytrisque obscure 
brunneo-piceis et marginibus rufo-brunneis ; antennis pedibusque 
infuscatis.

This species is very similar to C. ruficollis, Kies., but the 
colour is very different, being brownish with a darker 
shade ; the thorax and the elytra (except at the base) have 
both reddish-brown margins; the thorax is more perfectly 
arched in outline, and the oblique carina at the posterior angle 
is more conspicuous, being red, and the appendages to the 
antennal joints are as long again as in C. ruficollis. 
Hab. Kuma Kuni in Higo. One male example. 
Drilaster unicolor, sp. n. 
Niger, vix nitidus ; elytris dense rugoso-punctatis ; antennis pedi- 
busque concoloribus. 
L. 6% mill. 
This species is extremely similar to D. awillaris, Kies.,
