ACRIDIIDAE — ACRIDIINAE 49 



between coxae ; tegmina linear, lateral, distant, 

 with only a few longitudinal veins ; abdomen 

 of female tapering regularly to a pointed tip ; 

 ovipositor normally exserted. 



Asemophcs Scudder. 



e'^. Face rather strongly oblique, the angle it makes 



with the fastigium varying about from 55° to 67° ; eyes 



elongate, almost or quite twice as long as broad ; portion 



of metasternum lying behind the lobes subtriangular, 



not greatly broader than long ; tegmina linear and 



lateral or absent. . . Aptenopedes Scudder. 



Of these genera Melanoplus is the dominant ty|3e and the most 



prolific in species of anj'- North American Orthoptera, having 



within om* borders alone one hundred and twenty species or 



more. Podisma (Pezotettix Burmeister) is the most peculiar in 



distribution, its eight species being confined to high altitudes or 



latitudes and to two great districts, one in the west from Alberta 



to New Mexico, one in the east from New York and Ontario to 



Maine. The other well endowed genera belong mostly to the 



western half of the continent, Aeoloplus with ten species being 



found from the Yellowstone to Mexico ; Bradynotes with seven 



species confined to the extreme northwest ; and Hesperotettix with 



seven species having much the same range as Aeoloplus but wider, 



one species being confined to the eastern half of the continent and 



found indeed only on or near the Atlantic border. Of the genera 



with two or three sjjecies each, Aptenopedes and Paroxya are 



confined to the Gulf or the Gulf and Atlantic States, Campylacan- 



tha to the plains and prau'ie region from Nebraska to Texas, 



Paraidemona to southern Texas and Poecilotettix to the southern 



part of the Pacific coast. Of the remaining genera with one 



species only in the United States, Gymnoscirtetes and Eotettix 



are confined to Florida ; Asemoplus to the extreme northwest ; 



Hypochlora, Dendrotettix, Paratylotropidia and Phoetaliotes 



range between the Rocky Mountains and the Mississippi from 



various points northerly between Alberta and Texas ; Phaedro- 



tettix, Rhabdotettix and Cyclocercus are found in southern Texas ;
