Eyes emarginate by the raised edge of tlie gense. Antennae 

 witli the 3rd joint elongate, club 3-jointed, 9tli elongate-triangular, 

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

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

 Coxse distant, prosterual process very broad, metasteruum short,

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

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

 warded to me.
