cursoria

Century Dictionary and Cyclopedia

1. In Latreille's classification of insects, one of two prime divisions of Orthoptera (the other being Saltatoria), distinguished by their mode of progression, and by having tubular instead of vesicular tracheæ. The division comprised the three leading types of Forficula, Blatta, and Mantis, being therefore equivalent to the modern Cursoria plus the Gressoria and Euplexoptera.
2. A suborder of Orthoptera, containing only the Blattidæ or cockroaches; the Dictyoptera of Leach. In this restricted use of Cursoria, introduced by Westwood, the remainder of Latreille's Cursoria are called Ambulatoria (the Phasmidæ) and Raptoria (the Mantidæ).
