Fore-wings of Heteroptera, showing thickened veins and arrangement of veins in membranous tip characteristic of various families /, Capsidae; 2, Pyrrhocor'idac ; Lygaeidac; 4, Coreidac; j, \abidae; 6, Acaiitliidac (.\fter Comstock) bug he refers to an insect of the Q«:der Hcmiptera. The insects of this order are readily recognized by the strong, pointed suck- ing beak which extends from the head between the legs, and in which are inclosed the other mouth-parts, as already described (see p. 17). They develop with an incomplete metamorphosis, as has been described for the squash-bug (p. 50), which is a good ex- ample of one group. The name of the oedfer, Hemiptera, is de- rived from Jicjiii (half) and ptcron (wing), but is really applicable to only one aitborder, the Heteroptera. The name Heteroptera has a similar significance, referring to the fore-wings, which have the 107.
