 at base and apex, testaceous ; hind tarsi with the basal about as 

 long as the apical joint, and double the length of the second.

Type in the Pusa collection. 



The vei\y distinctly sinuate radial nervure is remarkable, and 

 exactly resembles that of Catoglyptus fortipes, Grav., to which it 

 is also allied in its unusually stout femora ; but the equally biden- 

 tate mandibles, subsessile abdomen and the structure of the 

 nervellus pi-eclude its inclusion in that genus. It is also very 

 distinct from most species of Tryphon in the complete absence of 

 an areolet and metanotal arese. 



Described from a single male.
