Genera and Species of Ilymenoptera. 205 



apex J tliere is a small area narrowed towards the apex on the 

 middle of the median sei^ment at the base ; the legs are 

 longish ; the anterior tarsi twice the length of the tibia? and 

 curved at the base ; the apex of tiie penultimate joint of the 

 hinder tarsi has a bunch of stifF longish bristles. The genus 

 Aglaocri/ptas comes near to it, but may be kn9wn by the 

 circular metathoracic spiracles and by the areol^t being 

 narrowed above. 



Most of the species in this genus have the metathorax more 

 or less red.
