Long. 18'5 mm. 



Ilab. Portuguese East Africa. 



I'liis species is rather longer tlian the one described imme- 

 diately before, but tlie thorax is shorter. The posterior part 

 only of the head is covered with erect set?e, theclypeus being 

 naked, shining, and very narrow. The antennae, like the 

 elytra and the lower surface of the body, are of a bright 

 reddish-testaceous colour and the antennal club is long. Tiie 

 legs and claws are of the normal form. 



The following species belongs to the recently formed genus 

 Diaclaspus of Brenske, differing from CUtopa chiefly by the 

 form of the front tibia", which have three teeth, and the 

 absence of sharp ridges on the head.
