In the Typical Coleoptera the mouth-parts are of the ordinary type ; the head is not prolonged into a snout; the gula is present, there being two gular sutures, at least, before and behind (Fig. 6oi, b); and the epimera of the prothorax are not prolonged so as to meet on the middle line of the body behind the prosternum (Fig. 612). Family ClClNDELlD^ (Cic-in-deri-dae). The Tiger-beetles. The graceful forms and beautiful colors of the greater number of the tiger-beetles have made this family one of the favorites of students of Coleoptera. To this family belong the most agile of all beetles; and they are not merely swift of foot, but are also able to fly well. They are found on bright, hot days in dusty roads, in beaten paths, and on the shores of streams. They remain abso- lutely still until we can see them well but are still out of reach ; then like a flash they fly up and away, alighting several rods ahead of us. Before alighting they always turn so that they face us, and can thus watch our movements. Their popular name is suggestive of their predaceous habits, and of the spots with which many are marked. They are usually a metallic green or bronze, banded or spotted with yellow. Some are black; and some that live on white sand are grayish white, being exactly like the sand in color. A useful character for distinguishing the members of this family is the fact that the terminal hook of the maxilla (the digitus) is united to this organ by a movable joint (Fig. 618, h). The sexes of the tiger-beetles can be dis- tinguished, except in Amblychila^ by the sixth abdominal segment of the males being notched Fig, 618. 11 1 1 M so as to expose a small seventh segment; while in the females only six segments are visible.
