422 THE INSECT WORLD. 
The Agrions, which are of the same family, have the body white, 
brown, or green, and the eyes very prominent. They are more 
slim and graceful than the Libellulas, properly so called; their 
larvee are very elongated. 
In the spring, one meets in the woods with insects having large 
heads and elongated thoraces. The females have a long auger, 
with which to deposit their eggs under the bark of trees, where 
their larve, which feed on insects, and twist themselves about 
like small serpents, live. The pups are also very active; they

resemble the adults:very much, and have the wings laid against 
the body. ‘These insects, which are met with everywhere, but 
always in small numbers, are the Aap/idras, which we see repre- 
sented (Figs. 395, 396, 397) in the state of larva, pupa, and adult, 
and the Mantispas (Fig. 398), one species 
of which is common in the south of Europe. 
M. Blanchard classes in the same tribe the © 
genus Semblis, whose larve are aquatic, with 
scaly heads, provided with eyes, and with 
curved mandibles and short antenne. The

those of fishes. Nevertheless the pupz live on land, not in water.
