Division PROSTEMMARIA. 



Nabiua, Stlil, En. Hon. iii, p. 106 (1873). 



Stal's name cannot be employed for this division, as he used 

 Prostemma as a synonyni for yahis. 



As in the previous division, the pronotum is not narrowed and 

 developed anteriorly into a distinct collar ; the Lead is usually, 

 but not invariably, immersed to the eyes, which touch the anterior 

 margin of the pronotum ; the rostrum is longer, third joint 

 extending to beyond base of head ; ocelli present.
