OF DOUBTFUL GENUS. 



bistigmata Say, Bost. Journ, Nat. Hist., i. 264 (1836). The open 

 areolet allies it to Apanteles., but the distinct radial vein and 

 supplementary stigma render the location of the species 

 doubtful. 



mellipes Say, Bost. Journ. Nat. Hist., i. 261 (1S36). Agrees with 

 Apanieles except in its distinct radial vein and subfusiform 

 abdomen. The " thorax with its two oblique impressed 

 lines confluent behind" is also a peculiar character, although 

 there is an indication of it in Microplitis ceratomice. 



robinice Fitch, Fifth Report, p. 56 (1S59). The open areolet 

 points to Apanteles^ but the brevity of the description pro- 

 duces doubt.
