II. TUBERCULATUS GROUP 



Median segments of male flagellum not widened; pronotum entirely 

 black; prepectal carina complete, its dorsal end moderately strong, 

 curved forward to near front margin of mesopleurum; lower half of 

 mesepimeron almost bare, with a few hairs along its hind margin 

 above; front and middle coxa and trochanters of male not specialized, 

 except that in D. terebrans terebrans the outer side of the middle coxa 

 has rather dense hairs; nervellus broken near or a little above the 

 middle; hind femur about 0.52 as long as deep, rather densely punctate; 

 propodeum rather short, its basal half with rather prominent median 

 longitudinal ridges; ovipositor sheath about 1.2 to 1.7 as long as front 

 wing; dorsal lobe of tip of lower valve of ovipositor tapered posteriorly, 

 with about seven ridges most of which slant a little forward and down- 

 ward (fig. 330,d). 



This group includes the two Holarctic species described below and 

 (Ephialtes) Dolichomitus crassus (Morley) 1913 (new combination) 

 from India.
