Century Dictionary and Cyclopedia
- One of the two prime divisions of hemipterous insects founded by Latreille in 1817; a suborder of Hemiptera, contrasted with Heteroptera. It contains a very large number of bugs of the greatest diversity in form, normally with large wings, and hemielytra of like texture throughout (whence the name), which are usually folded in a slanting direction. They have a blunt face with inferior rostrum, eyes and ocelli usually present, antennæ commonly inserted in a depression below the eyes, and legs adapted for either walking or leaping. The group is often elevated to the rank of an order. It is principally composed of the Cicadariœ, of which the families are numerous, as Cicadidœ, Fulgoridœ, Membracidœ, Cercopidœ, etc.; but it contains also the aphids or plant-lice, the coccids or scale-insects, the Aleurodidœ, and Psyllidœ, which are often grouped under the name Phytophthiria.
- A group coextensive with the preceding, except that the Phytophthiria are excluded. Auchenorhynchi is a synonym of Homoptera in this sense.
GNU Webster's 1913
- n. A suborder of Hemiptera, in which both pairs of wings are similar in texture, and do not overlap when folded, as in the cicada. See hemiptera.
