the Dascillida dc. of Japan. 113 
Black, shining, parallel at the sides, with greyish pubes- 
cence; the head widest at the eyes, gradually narrowing to 
the neck, microscopically punctulate ; the thorax clear red, 
transverse, as wide as the elytra, deeply incised at the basal 
angle, with a deep fovea or pit just within the lateral margin 
at the widest part; the scutellum widest at the base; the 
elytra evenly but rather rugosely sculptured ; the legs, tibie 
palish, thighs and tarsi infuscate ; the antenne, second joint 
very small, joints 3 to 10 apically strongly pectinate, joints 
5 to 9 having appendages longer than the joint itself. 
The pectination of the antenna is very unusual in Siélis, if 
not altogether exceptional in the genus.

rently all males.
