CLASSIFICATION OF THE HORNTAILS AND SAWFLIES, OR THE SUB-ORDER PHYTOPHAGA

Abstract

This family is very sharply separated from the Selandriidœ, Dineuridœ and the Tenthredinidœ by having only one marginal cell in the front wings, while from the Hylotomidœ, Lophyridœ, Perreyiidœ and the Pterygophoridœ which also have only one marginal cell, it is readily distinguished by pteropterological and antennal characters, and especially by the basal nervure in front wings uniting with the subcostal vein far from the origin of the cubitus.
