Dark reddish-yellow; head bright yellow, with a small, rather long,

 dish yellow ; wings hyaline, the basal nervures brown, those of the 

 apex reddish-yellow ; discocubital cell with two maculae ; abdomen 

 strongly compressed, towards the apex darker, often brown. 



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

 give a free translation of the original description. 



Type. — Location unknown. 



This species has hitherto been placed among the Ophions, 

 but a glance at the description shows at once that it belongs 

 to the genus Enicospilus. The identity of this species is in 

 doubt, as the " small tubercle " may not be constant and the 

 other characteristics given are not definite enough. It is, 

 however, very closely related to E. fuscicornis Cam., which is 

 possibly a synonym. The characters agree so far as given 

 and the distribution offers no difficulty.
