In other groups the perfect insects are wingless, or if i^re- sent, aborted and useless for flight. They are all furnished with long slender antennae consisting of from 11 to 25 joints; the head is large, rounded in front, with convex eyes, and three ocelli (wanting in the wingless forms). They can be collected into a small tube on fences or tree trunks, or shaken into a net or umbrella; but they must be handled very gently, and are best placed in dry tubes, and Fig. 16.—Philotarsus fi-ogyatti (Ender- lein).
