FAMILY CYNIPIDJ). 153 



thirteen-jointed in ? and fourteen in $ ; so that this 

 third group merely differs from the first in not having 

 a cup-shaped depression, and in the $ having one 

 joint less in the antennae. 



The " Figitidze " were divided by Thomson into 



i. The Allotrina, with the second abdominal segment 

 longer than the third and sub- sessile. 



ii. The Anacharina, Figilina, and Onychinia, which 

 all differ from the Allotrina in the abdomen having 

 the second segment not, or but little, longer than the 

 third. The three sub-tribes were separated by the 

 relative lengths of the second and third segments of 

 abdomen. 



In a subsequent paper (Opus. Ent., p. 778) Thom- 

 son divided the family into four groups Cynipina, 

 Allotrina, Figitina, and Ibalina, and pointed out a 

 new character whereby they might be distinguished, 

 namely, by the position occupied by the cubitus on the 

 transverse basal nervure. 



A valuable and instructive paper was publised by 

 Foerster in 1873 (Verh. z.-b. Ges. Wien, xix). Here 

 we have defined three main groups : first, Ibalina ; 

 second, the Cynipina ; and third, the parasitic spcies, 

 which were distributed among five sub-families of 

 equal value to the Ibalina and Cynipina namely, the 

 "Allotrioidse" the " Eucoeloidse," the " Megapelmoidae," 

 the " Onychioidae" and the " Figitoidde." 



Reinhard monographed (B. E. Z., iv, 204-45) the 

 central European species of Figitides, and united 

 Megapelmus, &c., with Figites, from which they were 

 separated by Hartig. He described the Figitides 

 (which comprised the Onychina, Figitina, and Anacha- 

 rina of Thomson) thus : 



Antennae maris quatuordecem-, feminae tredecem-articulatae. 



Segmentum secundum dimidio abdominis brevius. 



Alarum cellula radialis latitudine ad summum duplo longior. 



A useful and admirable work followed in the same 

 year from Griraud. The lamented author divided the
