Paratypes in the British Museum (Natural History.) 



Many specimens reared from the eggs of Anaplie infracta by Mr. 

 C. C. Gowdey, together with Telenomus gowdeyi, on which it must be 

 a secondary parasite. The area between the two medial carinas on 

 the propodeum varies in showing from one to three indistinct carinae, 

 the type-specimens being as given in the above descriptions. The 

 color also varies considerably especially in the male, being at times very 

 similar to the description given for the female. 



Genus HORISMENUS Walker. 



In working with these minute forms it is necessary to use the highest 

 magnification of the Zeiss binocular microscope to see certain of the 

 characters such as the sculpture of the first segment of the abdomen. 



The following table using in part characters not mentioned by Dr. 

 W. H. Ashmead will separate the females of the species known to
