140 Mr. F. P. Pascoe on the Colydiide 
each side, the disk simply tuberculato-setose; elytra broadest in the 
middle, the edges tuberculate, the tubercles arranged in rows on the 
disk, two small buff-coloured fascicles of hairs at the base of each 
elytron and two more towards the apex; body beneath dull black, with 
grey sete; antenne and legs black, setose, tarsi ferruginous. Length 
34 lines. 
A fine and very distinct species, differing in many respects from 
Hyberis araneéiformis, as a comparison of the descriptions of the two 
will show. I have another species, from Java. 
ATYSCUS. 
Caput immersum, subquadratum. Antenne setigeree, basi tectse, 10-arti- 
culate, articulis basalibus haud incrassatis, clava articulo unico oyvato. 
Prothorax transversus, antice bisinuatus postice constrictus, lateribus 
rotundatis, crenato-setosis. Elytra ovata, convexa. Pedes elongati, 
tibiis fusiformibus, setigeris, ¢arsis gracilibus. Corpus ovatum, con- 
vexum, setoso-squamosum. 
The club of the antenne in this genus appears to be composed of 
only one joint, as in Apeistus and Hyberis. From the latter of these 
genera Atyscus differs in the margins of the prothorax not being 
toothed, in its sete assuming more the character of scales, and in the 
absence of tubercles. The eyes, as in Hyberis, are not, or only 
very sparsely, setose. In Trachypholis and Chorites they are com- 
pletely so. 
Atyscus arqutus. (Pl. VIII. fig. 8.) 
A, latus, fuscus, griseo squamatus; elytris breviter ovatis, basi vix con- 
strictis, lateribus subparallelis. 
Hab. Tondano. 
Broadly ovate, dark brown, covered with small, greyish, squamiform 
hairs; head subquadrate; antennze 10-jointed, the first three joints of 
nearly equal size, the remainder, except the last, shorter and more or less 
obconic, furnished with a whorl of stiff setee, the tenth ovate, but not 
thicker than the others ; eyes round, not setose ; prothorax transverse, 
the sides rounded, with a fringe of stiff scales; scutellum small, dis- 
tinct; elytra short, scarcely contracted at the base, the sides nearly 
parallel, the disk with the scales arranged in rows; body beneath dark 
brown, subnitid, with small oblong raised lines; legs dark brown, 
fringed ; tarsi slender, ferruginous. Length 23 lines. 
Atyscus squalidus. 
A, oblongus, fuscus, griseo squamatus ; elytris ovatis, lateribus rotundatis. 
Hab, Sarawak. 
Oblong-ovate, dark brown, with small squamiform hairs; head with
