This modest brown yellow-winged locust has been taken by the 

 writer in Florida at all points where collections have been made. 

 At Ormond it was found mating on March 11, and at Dnnedin 

 both adults and nymphs occur in small numbers throughout the 

 winter. It is found principally in old fields, open pine woods and 

 along roadsides and railways. Its flight is usually short, and 

 stridulation while on the wing much more feeble than that of 

 xanthoptcra or even sulplmrea. It has been recorded by other 

 collectors from numerous stations in Florida as far south as Key 

 West, and is the prevailing form of Arphia throughout the State, 

 its congeners, xatithoptera and sulphured, being confined to the 

 northern third. Outside of Florida, graunhita is said by R. & H. 

 (1016, 176) to be "known from Wilmington, N. Car., and Waynes- 

 ville, Ga., westward as far as Thornasville, Ga.," while Davis has 

 received it from Caesar, Miss. Scudder (1900) accredits it by mis- 

 take to Nebraska, probably on a doubtful determination by Bru- 

 nei- (1897, 130). 



108. ARPHIA PSEUDOXIETANA (Thomas), 1870, 82. Northwestern Red- 

 winged Locust. 



Size and form of sulpJmrea but somewhat more slender. Color ex- 

 tremely variable, usually darker than sulphiirea, the male sometimes 

 nearly black, often with a dorsal sutural clay-yellow stripe on tegmina. 

 both sexes, but especially the females, often grayish-brown with numerous 

 fuscous spots and blotches, giving them a decidedly mottled appearance. 

 Prozona sometimes with a pale cross-bar, appearing like a collar; basal 

 portion of wings bright orange-red, very rarely deep yellow; hind femora 

 and tibiae as in sulphured. Vertex with concavity elongate-oval, wider in 

 female; apex truncate, closed in front, sides continuous with those of 

 frontal costa; foveolas large, shallow, rhomboidal. Frontal costa with 

 sides of upper third feebly converging, its median carina usually forking 

 just above the ocellus. Pronotum with front margin subtruncate or ob- 

 tusely rounded, median carina low, slightly higher on prozona, cut but 

 only faintly notched in front of middle; metazona nearly flat, often with 

 a large shallow basal impression each side. Length of body, $ , 22 24,

South Haven and South Frankfort, Mich.; Sidney and Valen- 

 tine, Neb.; Golden, Colo.; Pine Bluff, Wyo. ; Brandon, Man., and 

 Victoria, B. C. Scudder gives its range as "U. S. and Canada 

 west of Mississippi River," but it is known from Nipigon and 

 Sudbury. Ontario, and has been taken at a half dozen or more 

 points in Michigan, being the only Arphia recorded from that 

 State. It is also said by Thomas (1880, 109) to occur occasionally
