ICHNEUMON-FLIES, PART 2: EPHIALTINAE 181 



and the fuscous marking on hind tibia and tarsus either tending to 

 be diffuse as in the European Tromatobia angens, or not diffuse but 

 with the basal fuscous band on the hind tibia very narrow. This 

 latter variation seems to occur in arid localities. These illustrate 

 the types of variation that may be found, but the total number of 

 combinations of variations is more extensive. The subspecies is pres- 

 ent in Hawaii, where it is represented by a race similar in appearance 

 to that in southwestern California (as at San Diego). Presumably 

 it was introduced into Hawaii from that area.
