A NEW SPECIES OF THE RHYNCHOPHORID 
GENUS CRYPTODERMA 
DESCRIBED BY 
C. RITSEMA Cz. 
Cryptoderma plicatipenne, n. sp. o' and Q. 
Resembling as to shape Cr. brevipenne Rits. '), likewise 
from Borneo, but the elytra are more convex seen side- 
ways; differing by the less regular sculpture on the pro- 
thorax and elytra; the punctures or pits are less numerous 
and consequently their interstices broader; the punctures 
are deeper and their interstices raised, which gives an un- 
even aspect to the upper surface especially on the sides 
of the elytra where the interstices are confluent. 
Length of the males as well as of the females, measured 
from the anterior margin of the prothorax to the apex of 
the elytra, 8—11 mm. 
Covered with a brownish crust and with linear white 
markings; these markings are however of a very different 
development not depending from the sex; in some indivi- 
duals they are entirely absent, in other specimens they are 
more or less incomplete, in still other ones the markings 
are quite normal like in discors Fabr. — The legs are of 
a somewhat more greyish colour. 
The thorax is slightly longer than in the middle broad, 
very convex; at the base two flat, semi-ovate, shining 
black spots, making the incrusted surface deeply bisinuate. 
The scutellum is small, more or less ovate.
