412 Mr. C. O. Waterhouse on new Genera 
Colocnemis, but narrower behind the eyes. Antenne with 
third, fourth, and fifth joints subcylindrical, the third one third 
longer than the following, the sixth and seventh joints shorter 
and broader at the apex, the eighth, ninth, and tenth sub- 
quadrate ; the eleventh oblong, rounded at the < apex. ‘Thorax 
large, transverse. Elytra short, very ample, convex, narrowed 
towards the base. Legs long and stout ; femora subcylindrical, 
flattened below ; tibies cylindrical, slightly flexuous especially 
the anterior ; the apical spurs hidden by the tomentum. Basal 
joint of the tarsi scarcely as long as the two following joints 
together ; apical joint large. Intercoxal projection of ‘the ab- 
domen ver y wide. Mesosternum very short, deeply trian- 
gularly emarginate. Metasternum very short. Body clothed 
with fomentum. 
This very remarkable genus is evidently closely allied to 
Celocnemis, but is quite unlike in form and general appear- 
ance to any "Heteromerous insect with which I am acquainted. 
Dysceladus tuberculatus, sp. nov. 
D. niger, opacus, dense fusco-griseo tomentosus ; capite fere plano, 
antice truncato; thorace magno, antice posticeque angustato, 
longitudine #2 latiore, antice fortiter emarginato, angulis anticis 
sat acutis, lateribus rotundatis, angulis posticis acutis retrorsum 
directis, superne convexo tuberculis minutis aspero; scutello 
parvo; elytris thorace vix duplo longioribus, basi thorace angus- 
tioribus, postice rotundato-amplatis ad apicem breviter attenuatis, 
convexis, ad suturam depressiusculis, tuberculis nitidis plurimis

The antennz of this species are black, the five basal joints 
are shining and almost impunctate, the sixth and seventh are 
delicately punctured, the eighth to eleventh are granular with 
a smooth central line on the upperside. The sides of the 
thorax in the specimen described are slightly angular in the 
middle. I have seen the head and thorax of a second, larger 
specimen, in which the sides are evenly rounded.
