The winged members of this order have four wings ; in one suborder the first pair of wings are thickened at the base, with thinner extremities which overlap on the back; in another suborder the first pair of wings are of the same thickness throughout, and usu- ally slope at the sides of the body. The mouth-parts are formed for sucking. The metamorphosis is incom- plete. The name Hemiptera is from two Grisek words: hemi, half, and pteron, a wing. It was suggested by the form of the first pair of wings in the true bugs. Here the basal half of these organs is thickened somewhat like the wing covers of beetles, only the terminal half being winglike. The second pair of wings are membranous, and when at rest are folded beneath the first pair. Within this order are grouped insects that differ greatly in form and appearance. These are dis- 6.
