ICHNEUMON-FLIES, PART 2 1 EPHIALTINAE 177 



infuscate; hind coxa black to fulvous; hind first trochanter pale 

 fulvous in male, fulvous to fuscous in female; hind second trochanter 

 pale yellow in male, light fulvous in female; hind femur fulvous; 

 hind tibia pale fulvous, with an indistinct subbasal infuscate band 

 and its apical 0.15± fuscous; hind tarsus stramineous, the segments 

 infuscate apically; abdomen entirely black, to ferruginous with only 

 its apex and apical sublateral spots on median tergites black, most 

 often with an intermediate amount of ferruginous. 



This species is aptly named, as the color is unusually variable 

 and the areolet may be either present or absent. Specimens from 

 the eastern half of North America tend to have less extensive black 

 markings than specimens from the western half, and specimens from 

 warmer situations tend to have less black than those from colder areas.
