p. 388. 



Habitat. — Canada. 



Host. — Unknown. 



Type in the Museum of Public Instruction at Quebec, Canada, and 

 not examined. The species has been placed in the table on the basis 

 of the original description and notes made by A. B. Gahan after a 

 study of the type. It appears to be very similar to radiafus, but is 

 probably distinct, apparently having clear hyaline wings.

Apanteles radiatus Ashmead, Proc. Ent. Soc. Wash., vol. 4, 1897, p. 162. 



Habitat. — New Hampshire; Illinois; Virginia; New York. 



Host. — Unknown. The type series was recorded from " a lepi- 

 dopterous larva feeding on Plantago major.'''' 



The National Collection contains, in addition to the type series, 

 two specimens of this species from Illinois, and one from Arlington, 

 Virginia, without further data. 



70. APANTELES FLAVOVARIATUS, new species. 



Very similar to papaipemae^ from which it differs in lacking the 

 prominent median longitudinal carina on the propodeum, and in the 

 second abdominal tergite being only half as broad at base as long 

 down the middle. 



Female. — Length, 3.3 mm. Face hardly broader than long, shin- 

 ing; vertex, temples, and cheeks smooth and shining; mesoscutum 

 very weakly punctate and shining; scutellar disk indistinctly
