The eyes meet on top of the head. In coloration and general appearance they are much like the preceding families but with the majority of them the wings are generally clear with only apical brown spots and sometimes they are a little smokv. These large d. agon-flies are abundantly found all through the summer. They are among the first to appear in spring and among the last to disappear in the autumn. Their flight is very strong, and the large are most ferocious- looking creatures. In fact, the largest and most powerful dragon- fly in the North American fauna is Epurschiia hcros Fabr. One of the commonest forms which may be seen in many parts of the country is Anax Junius Drury. On account of the strong flight of these insects they are frequently found far away from the place of their birth ieeking their prey in the fields and'about open places in the woods, busying themselves continually in the cap- ture of flies and even larger insects. The male and female of Auax /uiiius paired are common objects flying over the water. The female seems to prefer to lay her eggs in stagnant pools or in ponds where the surface is covered with duckweed and o'her aquatic plants. The female submerges her abdomen in la^ ng her eggs. According to Williamson, this species appears in large and compact ilocks, some of them numbering several hundred individuals, and they pass back and forth frequently near the ground as twilight comes on, seeking e-pecially swarms of midges. Six genera are represented in this country, mostly the species belonging to the typical genus
