 with sides feebly sinuate posteriorly, a small fovea in centre near base. Elytra 

 sub-quadrate, attentiate, and slightly rovmded to base ; nearly twice as long as 

 prothorax, with two basal foveae. Abdomen much shorter than elytra, gibbose, 

 attenuate to apex, punctuation a little stronger than on the elytra. Meta- 

 sternixm transverse, concave, with a blunt tooth on each side. Ventral surface 

 of abdomen deeply excavate, the margins of excavation sub-serrato-carinate. 

 Femora stout, narrowing to base ; anterior and intermediate pairs irregularly 

 dentate ; posterior pair bidentate towards base. Tibiae broadening from about 

 middle to apex. Tarsi with three joints : 1 very short, 2 and 3 about equal in

Hah.: Sarawak, Quop (13.iii.l4, 1 ^, found by sifting dead 

 leaves in low-lying jungle). 



The species can be placed in G-roup VII, near C. bironis Eaffr., 

 from New Guinea, which was the first described member of the genus 

 with 10-jointed antennae. C. sarawakensis is a larger insect, and can 

 be distinguished by the dentate femora. Superficially, it is very like 

 a large $ example of G. impar Raffr.

 widest at apex ; 2 transverse, narrower than 1 ; 3, 4, 5 transverse and compact ; 

 6, 7, 8 transverse, each gradually wider, 9 narrower ; 10 very large, transverse, 

 outer margin rounded, apical margin slightly curved, and meeting basal margin 

 in a point. Maxillary palpi with last joint large and rather oblong, rovmded at

 near shoulders. Abdomen very short, attenuate, and rounded at apex, with the
