Males 



I associate with the females of crantor, seven males from the same two Cretan localities. 

 Also, I associate with cloelia, nine males with the same data as the females. These two series of 

 males are beyond doubt different and confirm the specific validity of the two species. There is 

 a marked difference in the shape of the penis-valve ; in crantor it is narrow and evenly oval as 

 seen from above (Text-fig. 209) while in cloelia, the structure is relatively larger, broad medially 

 and rather abruptly narrowed to apex (Text-fig. 208). I have seen no male that I can with 

 confidence associate with evander, a species that in several respects is intermediate between 

 crantor and cloelia. 



The male of butalidis lacks the convergent eyes of the female and differs from the males of 

 crantor and cloelia in having almost hyaline wings and the coarse mesoscutal sculpture of its 

 female. 



The FALCATUS-Grovp 



Apanteles falcatus, the common and sole European representative species of this 

 group has usually been placed among the species that constituted Wilkinson's group 

 A and Marshall's section IV. I do not consider the relationship to be as close as 

 these authors believed. 



The genital apparatus of the male of falcatus and of caudatus is remarkable on 

 account of its relatively enormous size. There is no approach to this in any other 

 group of Apanteles known to me. 



The group is represented in N. America by three species, two of which are extre- 

 mely close to falcatus.

The genitalia of the male, though relatively large for Apanteles, are by no means so 

 large and exaggerated in appearance as in falcatus ; nevertheless, the paramere, as 

 in falcatus, is widely truncate at apex with the upper corner more pointed than the 

 lower one. The female is remarkably distinct because of its pale ovipositor sheaths, 

 a colour feature I have not so far met with elsewhere in Apanteles. The species is 

 not closely related to falcatus and caudatus, lacking the characteristic appearance of 

 the basal tergites peculiar to these two species.
