 forehead scarcely impressed ; eyes moderately prominent. Rostrum. 

 distinctly longer than broad, sides subparallel, genie scarcely

Type in the British Museum. 



Natal [coll. Pascoe\ 



I have seen only the type of this species, which was erroneously 

 referred to Phlyctinus callosus Boh. by Pascoe. The shape of the 

 elytra is unusual and gives the insect a distinctive facies. The 

 specimen is probably a female.
