SCUDDER. — GENERA OF MELANOPLI. 205 



Hesperotettix Scudder is found across the coutiuent, but only a single 

 species, brenpennis Thom., is known east of the Great Plains, and that 

 has been found only on or near the Atlantic border. The other species 

 are vin'dis Thorn., pacificus Brun. (undescr.), speciosus Scudd., and four 

 new species, including two which have often been confounded with one 

 of the foresoinj;. 



jEoloplus <ren. nov. is confined to the western half of the United States 

 from the Yellowstone to the Mexican border. I have seen no species 

 from further east than western Kansas and Nebraska, so that it does not 

 appear to reach the prairie region. There are ten species, of which 

 those already published are regalis Dodge, chenopodii Brun., turnbulli 

 Thom., and plagosus Scudd. 



Bradynotes Scudder is confined to the extreme northwestern United 

 States, and contains seven species, of which the only ones already 

 described are hispida Brun., and obesa Thom. (optmus Scudd.). 



Dendrotettix Riley has but a single and dimorphic species, quercus Ril. 

 (longipennis Ril.), ranging from Missouri to Texas. 



Podisma Latreille is used in replacement of Pezotettix Burmeister for 

 reasons given in Psyche (vii, 195). It has a wider distribution than any 

 other genus of Melanopli, being found in Europe and temperate Asia, as 

 well as in America. The American species occur in two great districts, 

 one in the west from Alberta to northern New Mexico, the other in the 

 east from western Ontario and New York to Maine. There are eight 

 American species, of which those already described are the following; 

 glacialis Scudd., stupefacta Scudd., dodgei Thom., marshallii Thom., and 

 oregonensis Thom. Eupodisma is a subgeneric term for primnoa Fisch. 

 de "W. of Siberia. 



Paratylotropidia Brunner is based on an undescribed species found 

 from Dakota to Texas. 



Melanoplus Stal is the dominant genus, with one hundred and thirty- 

 one species, but it is confined to North America. These species have 

 been grouped into twenty-eight series, but as, on account of its pre-eminent 

 importance, this genus is treated separately in another paper in press, no 

 further account of the species is given here. 



Phcetaliotes gen. nov. is based upon a single species, nehrascensis 

 Thom., found in the western part of the Mississippi basin, and beyond its 

 latitudinal limits from Alberta to Mexico. 



Paroxya Scudder has three species, mostly confined to the Atlantic 

 and Gulf States ; they are atlantica Scudd., hoosieri BlatchL, and 

 jioridana Thom.
