62 AMERICAN HYMENOPTERA. 



Type. — Location unknown to me. 



I have not seen a specimen of this species, and can only 

 give a free translation of Brull^'s description. There is 

 some question as to the right location and even validity of 

 the species; the linear macula may be an abnormality, and 

 the species belong in reality to the Genus Eremotylus, or a 

 second macula may have been lacking in the type and the 

 species, while belonging to the Genus Enicospilus, may prove 

 to have been already described.
