Coptengis. 



g. n. {typ. Sheppardi, Pascoe). 



Eyea emarginate by tlie raised edge of the gense. Antennae 

 with "the 3rd joint elongate, club 3-jointed, 9th elongate-triangular, 

 larger than the other two. Thorax much longer than broad, sides 

 parallel, base broadly emarginate. Elytra punctate, apex truncate. 

 Coxae distant, prosternal process very broad, metasteruum short, 

 ventral process broad, truncate. 



The brilliant colours of this genus (peculiar to the Malay archi- 

 pelago) give it a striking appearance. M. Chapuis had suggested 

 the above name in a provisional classification of the family for- 

 warded to me.
