Family LOCUSTARI.E Latreille. 



Like the Acridii, this family of Orthoptera is not well represented in 

 the Tertiary rocks; no specimens of either have been found in amber, ex- 

 cepting a few larvfB of this family. Yet almost all of the larger subfamilies 

 are present both in Eui'ope and America. The Conocephalidje, however, 

 which are represented in America by two species, have none in Europe, and 

 per contra, the Decticidse, which have three species in Europe, do not occur 

 in America. Two of the European species can not be placed, Locustites 

 maculata Heer from Parschlug and Decticus exstinctus Germ., from the 

 Rhenish coal. Ten species, including two referred to only by generic 

 names, have been found in the European Tertiaries, and five in America, 

 besides indications of others. Unlike the Acridii, the ?]uropean and Ameri- 

 can species show few points in common, the species wliich are referred to 

 the same subfamilies being widely separated. (July, 1884). 



Subfamily PHYLLOPHORIO.E St^l. 



The only European species of this group, which is best represented in 

 warm, temperate, and tropical countries, is Phaneroptera vetusta Heer from 

 Oening-en, and it is widely distinct from the single American species referred 

 here. (July, 1884.)

Lithymnetts Scudfl., ISuU. U. S. Geol. Geogr. Surv. Terr., IV, 532-533 (1878). 



A stout-bodied genus of Phyllophoridse, probably belonging near Steiro- 

 don, but dilfering from tlie entire series into which Steirodon and its allies 

 fall in the great length of its ovipositor, which is at least as long as the 

 abdomen ; while in Steirodon and its allies, so far as I know them, it is 

 seldom more than two or three times as long as broad ; it is also peculiar
