palæodictyoptera

Century Dictionary and Cyclopedia

1. An order of insects, now extinct, the remains of which have been found in Permian and older rocks. They appear to have combined the characters of the Hemiptera and the Neuroptera, as is well shown in one of the genera, Eugereon. This was a gigantic form, having net-veined wings recalling those of Neuroptera, while the mouth-parts were formed into a beak like that of the Hemiptera.
