2 HYMENOPTERA. 



if necessary but for the present, to solve the correct rela- 

 tionships of the species of this family, we have got to be able 

 to correctly identify them and it appears that this may mean 

 the use of many minute characters, easy to see and appar- 

 ently stable but whose value may drop to zero if interbreed- 

 ing descendants of any one of the species are obtained and 

 studied. So far these minute characters have stood that test 

 in the case of several species. 



The positions and relations of these genera will be fully 

 discussed in the sequel, the revision. 



Superfamily CHALCIDOIDEA Ashmead. 



Family TRICHOGRAMMATID^ Foerster. 



Subfamily Oligositin^ Ashmead. 



1. APHELINOIDEA genus novum. (Figs. 1 and 2.) 



Normal position. 



Female. — Normal for the subfamily, resembling in general 

 aspect some of the Aphelininae of the family Eulophidae, 

 especially in the pubescence of the fore wings. Tarsi 3- 

 jointed. 



(Cephalic aspect) head rounded triangular, the eyes large 

 and promxinent, the ocelli normal, 3 in the center of the ver- 

 tex, the latter broad, the lateral ocelli distant from the eye 

 margin, the eyes with scattered pubescence ; antennae in- 

 serted below the middle of the face but slightly above 

 (dorsad) an imaginary line drawn between the ventral ends 

 of the eyes, 5-jointed — scape, pedicel, 1 ring-joint* and 2- 

 jointed club, the funicle absentt, the 2-jointed club longest, 

 cylindrical, the pedicel much longer than wide, slightly over 

 half as long as the club. 



* In some specimens, which are in a better position, apparently two 

 distinct ring-joints but the second or distal one appears to be the rim- 

 med proximal end of the first club joint, there being no articulation 

 present between it and the basal club joint. 



t I have stated the segmentation of the antennae this way rather 

 than count the joint or segment succeeding the ring-joint as funicle 1, 

 because there is no differentiation present to represent a funicle, the 

 two joints succeeding the ring-joint being unequal in length but form- 

 ing a well defined club.
