226 Mr. J.S. Baly’s Descriptions of uncharacterized 
In C. ferrugineus the thorax is more convex, and, together 
with the head, more coarsely punctured ; the basal joints of the 
antennae, instead of being entirely red, as in C. Murrayi, are 
obscure rufo-piceous ; and the elytra are irregularly punctured 
over their whole surface. In C. Murrayi the elytra are irregularly 
punctured on the disk, but near the suture the punctures are 
arranged in longitudinal rows, the puncturing being also finer 
than in Gerstacker’s insect. 
Ceralces Walleri. 
Oblongo-ovata, convexa, rufo-fulva, nitida; antennis nigris, 
pectore, pedibus, antennarumque basi nigro-piceis; thorace 
elytris latitudine fere cequali, dorso leviter punctato, utrin- 
que unifoveolato; elytris subcrebre punctatis, punctis prope 
suturam subseriatim dispositis. 
Long. 45—5 lin. 
Hab. Zambesi River. 
Mouth nigro-piceous, epistome and vertex closely punctured ; 
lower portion of face just above the epistome impressed with three 
short longitudinal grooved lines. Thorax twice as broad as 
long, nearly as broad at the base as the elytra, sides rounded and 
narrowed from base to apex; disk somewhat distantly, sides 
rather more closely, punctured, 
The broad thorax at once distinguishes this species from either 
of the two mentioned above ; the punctuation of the thorax is also 
much finer, more especially on the disk. 
Ceralces spilota. 
Breviter ovata, convexa, fulva, nitida; antennis extrorsum, oculis, 
thoracis maculis tribus transversim dispositis, elytrorumque 
maculis octo, harum quatuor infra basim et quatuor vix pone 
medium positis, nigris; scutello nigro-piceo; thorace trans- 
verso, irregulariter punctato; elytris crebre punctatis, punctis 
prope suturam in seriebus gemellatis dispositis. 
Long. 33 lin. 
Hab. Zambesi River. 
In form of thorax and body closely resembling C. Walleri; 
rather shorter, however, and stouter than that species. Head 
coarsely punctured. Thorax feebly excavated on either side the 
disk. The black patches on the elytra, which are arranged in two 
transverse rows, vary in my specimens somewhat in size, and it 
is probable that in some individuals they are considerably enlarged
