semble the adults very much, and have the wings laid against 
the body. These insects, which are met with eerratiors but 
always in small numbers, are the Raphidias, which we see repre-

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 larvee are aquatic, with 
scaly heads, provided with eyes, and with 
curved mandibles and short antenne. The | ' 
larvee and the pupz breathe, like those of the is: 398—Mantispa pagana, 
Ephemere, by articulated external fillets or gills, analogous to
