This subfamily is quite distinct from tlic other two subfamilies, an<l is easily 

 recognized by the structural peculiarities of the mesonotum l)rought out in my 

 table of subfamilies. 



A full account of till' group is given in my paper entitled, "On the ( ieiiera of the 

 Eupelminte," published in the Proceedings of the Entomological Society of Wash- 

 ington for 1896. Since that paj^cr was published, however, a new tribe and some 

 new genera have been recognized ; these are characterized below. 



TABLE OF TRIBES. 



Mesonotum in femak-s always (U-piessed or imiiressed, concave or subconcavc, iiu'dially with usuallx- a tri- 

 angular elevation anteriorly, the jiarapsidal furrows not, or rarely, sharply deiiiied, never short ; in males 

 subcouvex, with the furrows rarely complete, not short nor curved off laterally Tribe I. Eupelmini. 



Mesonotum convex in both sexes, the parapsidal furrows delicate, but always complete, short and strongly 

 curved off laterally, the scapuhe short Tribe II. Tanaostiginini. 



TiuisF, I. KujicJiHini. 

 The im[jressed and incomplete mesonotal furrows in the females distinguish the 

 group. The males are not so reatlily defined, and are easily mistaken for males in 

 the family Cleonipiti<hr, the mesonotum being sometimes subconvex, with the fur- 

 rows complete or incomplete ; the mesopleura are, however, usuall}'- entire and this 

 peculiarity, together with the venation, the structural characters of the head, the 

 antennie and the metathora.x, will, in most cases, distinguish these insects.
