HYMENOPTERA. 93 
FAMILY II. 
PUPIVORA. 
In the second family of the Hymenoptera we find the ab- 
domen attached to the thorax by a simple portion of its trans- 
versal diameter, and even most frequently by a very small 
thread or pedicle, in such a manner that its insertion is very 
distinct, and that it moves on that part of the body(1). The 
females are provided with an ovipositor. 
The larvee are destitute of feet and mostly parasitical and 
carnivorous. 
I divide this family into six tribes. 
In the first, that of the Evanraxes, Lat., the wings are 
veined, and the superior ones, at least, are lobate; the an- 
tenn filiform or setaceous, and composed of thirteen or four- 
teen joints; the mandibles dentated on the inner side; the 
maxillary palpi composed of six joints, and the labials of four. 
The abdomen is implanted on the thorax, in several under the 
scutellum, and has an ovipositor usually salient and formed of 
three filaments. 
This tribe appears to form but the single genus 
Fanus. 
Sometimes the ovipositor is concealed, or but very slightly salient, 
and resembles a little sting. The ligula is trifid, a character which 
approximates these Insects to the preceding Hymenoptera.

Where the antennz are geniculate, and the very small, compress- 
(1) The first segment of the abdomen forms the posterior extremity of the 
thorax, and unites intimately with the metathorax, so that the second segment of 
the abdomen becomes the first.
