74 SPOLIA ZEYLANICA. 



slender, its apex reaching to the hinder ocelli. Hypopygium 

 long, plough-share shaped. Legs long and slender. Apex of 

 clypeus roundly incised. 



This new genus cannot well be confounded with any of the 

 described genera of Megastigminw. It comes nearest to Megas- 

 tignms, which may be known from it by the punctured scutellum 

 with a transverse furrow at the apex, by the distinctly 3-dentate 

 mandibles and by the shorter antennal scape, the top of which 

 does not reach to the ocelli. Characteristic is the spotted 

 abdomen, the red head and the thorax, and the projecting 

 cultriform hypopygium.
