tarsi browuish-ochrcaceous ; basal joint of antennas about as long- 

 as head, second and fourth joints subequal in length, longer than 

 third ; posterior femora prominently spined on inner margin, less 

 prominently spined on outer margin ; posterior tibia3 strongly 

 dilated for more than half their length, broadest at outer margin, 

 the edge of wliich is sharply tridentate, inner margin sinuate and 

 centrally dentate. 



Length 19 to 22 ; breadth between pronotal angles 7 millim.

Division PHYSOMERARIA. 

 Physomerai'ia, Stdl, En. Hem. m, p. 36 (1873). 



This Division differs from the Anisoscelarin by not having the 

 head longly produced in front of the antenniferous tubercles ; the 

 apices of the posterior femora do not reach the abdominal apex ; 

 the posterior femora are distinctly incrassated and more or less 

 distinctly spinous or tuberculate. — The Physomerana are confined 

 to the Ethiopian and Oriental Kegions.
