The extremely short antennae, the short robust legs, the flat- 

 tened face betv^^een the eyes, together with the absence of any 

 thoracic grooves, will separate Platycepha from any allied 

 genus.

Head smooth, nearly free from punctures ; surface flat, carina 

 and encarpge entirely obsolete, the interocular spaces being only 

 indicated by a faint line on the upper margin ; labrum flavous ;

 joint moderately, the second slightly thickened, second and five
