 Mange. Both hemispheres. 



Head subglobose, as wide as or wider than the thorax ; a lamellar 

 tubercle above the bases of the antennae, concave above ; eyes large, 

 oval; ocelli complete, round, rather close together, placed in 

 a triangle on the vertex ; antennae fili- 

 form, long, the scape thick, about as 

 long as the 2nd joint of the flagellum ; 

 pronotum with the posterior portion 

 raised, quadrate anteriorly, prolonged 

 into a sort of neck ; mesonotum very 

 short, its posterior margin nearly in a 

 line with the posterior margin of the 

 tegulae ; scutellum large ; median segment 

 flat above, steep at the sides ; posteriorlv 

 truncate, the upper surface with longi- 

 tudinal carinas somewhat as in Ampulex ; 

 legs long and slender; femora flattish. Wings — fore wing v\ith 

 one radial and three cubital cells ; the radial cell long, narrow, 

 acute at apex, not appendiculate ; the 1st cubital cell very little 

 longer than the 2nd, the 2nd nearly half as long again as the 3rd, 

 the 2nd and 3rd narrowed towards the radial cell ; the 1st trans- 

 verse cubital nervure geniculated close to its origin and giving off" 

 a subobsolete oblique nervure in the 1st cubital cell. Abdomen 

 pseudosessile, subcylindrical, with the margins of one or more 

 of the basal segments constricted ; the terminal segment in the 

 Eastern species acute in the female. 



Nothing is on record as to the habits of the Eastern species of 

 this genus.
