dorsal carination. In the present species the majority of the 

 specimens are decidedly' long-winged, i. e., having the tegmina 

 and wings strongly surpassing the apices of the caudal femora, 

 while in a number of specimens, these outnumbering the more 

 usual type in the eastern Nebraska representation, the teg- 

 mina and wings are extremely elongate, surpassing the caudal 

 femora by from one-half to two-thirds their length. The long- 

 winged type is that to which Scudder gave his name longipen- 

 nis. The tegmina and wings average shorter in the specimens 

 from Kearney, Neligh, North Platte and Haigler, Nebraska, and 

 Billings, Montana, than in those from any other locality. Every 

 one of seven specimens collected at electric lights at Lincoln, 

 Nebraska, by Prof. Bruner is of the very long-winged type, while 

 of thirty specimens from Billings, all taken in a sedgy area, but 

 two are of the verj^ long-winged form. 



The color variation is chiefly in that of the dorsum of the 

 pronotum and of the face. The former area may be uniform 

 with the general body color or ma}^ be supplied with a pair of 

 brownish diverging lines, the area between these may or maj- not 

 be infuscate or washed with ferruginous, while the extent and 

 depth of these lines and the embrownment of the enclosed area 

 on the occiput is variable in the same proportion as on the prono- 

 tum. The face may be concolorous with the remainder of the 

 head or supplied with a more or less distinct median vertical bar, 

 which in the more intensely colored specimens is almost blackish 

 and generally considerably expanding ventrad, although it ma}' 

 be nearly subequal in width. Interior specimens do not show 

 this dark l^ar, as far as our material goes, except in the case of the 

 Indiana material called indianense by Blatchley and of a single 

 female labelled "Colorado," but from the coastal sections this 

 form generally outnumbers the pale faced type which occurs in 

 exactly the same situations. In the coastal area of Texas the 

 pale faced type is proportionately more numerous tlian in the 

 eastern coastal section. The occasional presence of a similar 

 facial bar has also been noted bj' us in 0. luilitare. 



From observations made in New Jersey by the junior author 

 during the summer of 1914, it is evident that the young of the 

 present species found in the eastern coastal region exhil)it two 

 color forms, one with a striped face, the other with a uniformly
