CLASSIFICATION OF THE EUPHORINAE 
This group has been consistently divided into two subfamilies, 
based on the number of cubital cells, since the publication of Foerster’s 
classification of the Braconidae (1862). In 1923 (13, p. 4), however, 
the present writer indicated that the Meteorinae do not represent 
a natural group distinct from the Kuphorinae and might need to be 
united with that subfamily. Subsequent study has emphasized the 
artificial character of the division. Accordingly, the two subfamilies 
are combined in this publication. 
The Euphorinae may be characterized as follows: 
Head transverse to quadrate; mandibles bidentate, crossing at apices and 
fitting against clypeus; clypeus separated from face by an impression; anterior 
margin of clypeus subtruncate, more or less reflexed; maxillary palpi with 5 or 6 
segments; labial palpi with 2, 3, or 4 segments; eyes prominent, usually bare or 
sparsely hairy, very rarely thickly hairy; temples and cheeks margined; occiput 
usually margined but with the carina often interrupted medially; transverse 
impression at base of scutellum broad and deep; prepectus margined; legs slender; 
calearia of posterior tibia varying from very short to half as long as metatarsus; 
2 or 3 cubital cells, very rarely only 1; radial cell ranging from very small and more 
or less lunate to very large, measured on wing margin in some specimens not more 
than one-fourth length of stigma, in others extending nearly to apex of wing; 
rarely, radial cell not defined, the radius lacking; first cubital and first discoidal 
cells either separated or confluent; recurrent vein very rarely absent; medius 
ranging from well developed to obsolete; first brachial cell open at apex; subdis- 
coideus not interstitial; submediellan cell large, rarely not defined. First ab- 
dominal tergite petiolate, the spiracles at or behind the middle; second and third 
tergites connate, large, usually but not always carinate at sides, usually over- 
lapping on venter; apical margin of second tergite rarely distinct; ovipositor 
sheaths either concealed or prominent. 
This subfamily is most closely related to the Leiophroninae, but 
can be distinguished by the more definitely petiolate first abdominal 
tergite and the position of the spiracles of this tergite. 
As in most of the major subdivisions of the Braconidae, the sub- 
family Kuphorinae contains several more or less anomalous genera, 
such as Aridelus, Wesmaelia, Myiocephalus, and Cryptoxios, the 
relationships of which are not apparent. However, they align them- 
selves so definitely with the Euphorinae on the basis of characters 
distinguishing this group that they must be placed here. Schmiede- 
knecht proposed the subfamily Helorimorphinae for his genus Helori- 
morpha, but the characters defining it do not appear to be of sub- 
family value. 
KEY TO THE GENERA OF EUPHORINAE

Anterior wing with 2 cubital cells, rarely with only 1, never with 3; radius 
composed of not more than 2 abscissae, rarely entirely lacking_----_ 
2. Lateral margins of second abdominal tergite not carinate; first tergite 
very long and slender; notauli lacking; radial cell shorter than 
stigma; antennae always 18-segmented; ovipositor not exserted

ening strongly behind middle; notauli distinct; radial cell longer 
than stigma; number of antennal segments variable but always more
