Orthoptera palaearctica critica: II. Genus Tropidopola St. (Acrid.)

Abstract

The first species of Tropidopola vas described by Marschall in 1836 under the name Gryllus cylindricus from Sicily. Three years later Serville (1839) described in his g-enus Opsomala an O. sicula from Sardinia, which also belongs to Tropidopola; another species O. pisciformis, described by Serville in the same book fi-om Java and Egypt and regarded by some later authors as synonymous with cylindrica, has nothing to do with the genus since it is stated to have «disque du prothorax... distinctement tricaréné»; it is possible that the specimen fi-om Egypt which Serville mentions under pisciformis was actually a Tropidopola, but the description was obviously based on the specimen fi-om Java.
