GENOTYPE, Mesocliorus scutellatus, Grav. 



Head with the genal sulcus wanting ; frons entirely and face 

 often black, the latter never with (he orbits alone determinately 

 pale and in tf always pale throughout. Lateral thoracic carime 

 often basally obsolete. Abdomen subpilose discally, with the 

 postpetiole margined in both sexes. Upper wings with the lower 

 basal nervure usually postfurcal and the anal emitted from the 

 centre of the second discoidal cell, which is externally acute 

 below. Hind wings with nervellus nearly always geniculate. 



Range. United States, Europe, Ceylon. 



This genus differs from Mesocliorus in possessing genal sulci, in 

 its geniculate or intercepted nervellus, and in the anal nervure 

 not being emitted from above the centre of the first recurrent ; 

 in the last character it agrees with Stictopisthus, Thorns, (entirely 

 overlooked by Ashmead in 1900), which has the nervellus entire 

 and not intercepted.
