the difficulties involved in this case being fully discussed under the 

 latter species. 



Although Kirby2 has referred Locusta -pollens Fabricius,^ to 

 Scudderia, we have omitted the species from the present treatment, 

 as we are of the opinion that it does not belong to this genus. 



The present genus is found from Nova Scotia to southern Brit- 

 ish Columbia, southward to the Isthmus of Panama, and in 

 South America is known only from Trinidad (Caparo) and Dutch 

 Guiana (Paramaribo). In the arid regions of the western United 

 States and Mexico it is not to be fomid in the desert proper, but 

 almost everywhere in the desert hills and mountains. The species 

 of the genus are largely nocturnal, manifesting but little activity' 

 during the day. All but one of the species are normally uniform 

 green in general coloration.

Scudder in his revision of the Scudderiae,* has incorrectly sup- 

 posed Heer's name Phaneroptera suturalis to apply to the present 

 species, and has sought to retain it for what from Heer's de- 

 scription, appeared to him to be a color form. 



Heer described Phaneroptera suturalis from New Georgia,^ but 

 in his treatment apparently mistook the locality for Georgia in 

 the United States. The specimen was doubtless properly labelled 

 "New Georgia," one of the Solomon Islands, since the description 

 further shows the species to belong to the genus Diicetia, not agree- 

 ing at all with any species of Scudderia. 



Lugger has given two excellent figures of the sexes of the present 

 species from Minnesota unfortmiately calling them *S. pistillata,^ 

 he had doubtless both species before him. This record is the 

 first which applies, at least in part, to this species from west of 

 the Appalachians. Bruner's material shows that it was this
