ICHNEUMON-FLIES, PART 2\ XORIDINAE 499 



hind trochanters and extreme base of hind femur fulvous brown; 

 apical margin of hind femur and basal 0.15 of hind tibia white; hind 

 tarsus blackish brown to light brown, its fifth segment always black; 

 wings subhyaline. 



A female from Raleigh, N. C, has the front and middle coxae, 

 femora, and tibiae infuscate, which makes this specimen somewhat 

 intermediate to the subspecies piceatus. One female from Mahnomen 

 Co., Minn., has the hind coxa fulvous, as in the subspecies sierrae. 

 The type of X. australis, from Louisiana, is difficult to classify. It has 

 some of the characteristics of the subspecies piceatus and mexicanus, 

 as well as of the present subspecies. Its placement must be arbitrary 

 until the subspecies of the southern United States are better under- 

 stood.
