542 Mr. T. Vernon AVollaston on the 
malleated, but nevertheless nearly unconstricted in front, 
for its legs being a good deal thickened, and for its body 
being of a piceous hue, with the exception of the elytra — 
which are conspicuously paler, or of a clear rufo-testaceous. 
45. HiMATiUM {jiov. gen.). — In its narrow, parallel, 
cylindric, but not very convex, body — Avhich is of a rufo- 
piceous hue, and sparingly studded with elongate, partially- 
erect, fulvescent hairs — the interesting little Cossonid for 
which the present genus is proposed, and Avhich has been 
communicated by jNIr. Fry as having been received from 
Malabar in southern India, will be easily recognized. Its 
surface is slightly shining, and (with the exception of the 
head, Avhich is convex and almost free from punctation) 
coarsely and very densely sculptured; its rostrum is 
parallel, but nevertheless somewhat narrow and not very 
elongate ; its eyes are depressed, and greatly separated 
fi'om each other, — so much so indeed that they are barely 
visible when the insect is viewed from above ; its antennae 
(which are inserted just before the middle of the rostrum) 
have their scape rather abbreviated, straight, and robust, 
and their fimiculus-joints (with the exception of the first 
one), short, subequal, and submoniliform ; its prothorax is 
oval, and a good deal constricted in front ; its metasternum 
is elongate ; its coxje (even the anterior pair) are wide 
apart, and the third articulation of its feet is nearly 
simple. 
46. Pholidonotus {nov. gen.). — I am indebted to 
Mr. Pascoe for the loan of the somewhat obscure and in- 
significant little insect (captured by Mr. Wallace at 
Sarawak, in Borneo) to contain which the present genus is 
proposed ; and, apart from its rather diminutive size, and 
piceous, opake, densely-sculptured surface, it is remark- 
able amongst the Cossonidce for being one of the very 
few forms the surface of which is clothed (as in Pholido- 
forus from Japan) Avith scales, — some of them being coarse 
and mud-like, and others thick, robust, and setiform. In 
the inferior position of its depressed eyes (which are 
scarcely visible when the specimen is viewed from above), 
as well as in the structure of its rather long and narrow, 
but straightened, rostrum, and in the fact of its surface 
being piceous and (at any rate) clothed, I think there can 
be little doubt that it displays a certain degree of affinity 
Avith the Indian genus Himatium ; but, in addition to its
