GEOLOGICAL SUEVEY OF THE TEEEITORIES. 457 



give here, from my field-notes, a description of a living specimen of 

 what I supposed was (E. coralUpes. 



Female. — Occiput mottled with dark-brown 5 a whitish spot behind 

 the upper canthus of each eye ; the vertex and the broad frontal ridge 

 light ashy-blue, the margins of the ridge light-yellow; parts of the mouth 

 pale carneous, the clypeus having the deepest tinge. That jjart of the 

 neck which is mostly hid by the pronotum bright blue. The lateral 

 carinse of the prouotum have a tolerably broad x>ale stripe along the 

 uf>per side of each. The whitish parts of the pronotum and elytra have 

 a bluish tinge, except the stripes along the dorsal margin of the latter, 

 which are pale yellow. The wings are a clear lemon-yellow at the base; 

 the black band sends a broad ray up the front submargin riearly to the 

 base; the marginal vein being yellow, the apex trausx)arent, with dark 

 nerves. The base of the abdomen dark bluish. The under side of the 

 body light brownish-yellow; the pits or depressions in the sternum red. 

 The four anterior legs a pale asby-blue. Inside of the posterior femora 

 and i^osterior tibiae a bright coral-red. Spots of the elytra as described 

 by Haldeman. Sometimes the whitish and ash colors of the head, 

 pronotum, elytra, and legs are replaced by bright orange-yellow, but 

 the dark brown spots and patches appear to be permanent. 



At Ogden, in Utah, I met with a grasshopper, which in size, shape, 

 markings of the elytra, carvings of the head, mode of flight, and some 

 other respects, corresponds exactly with (E. corrallijjeSj but the wings 

 are red at base, and the interior of the posterior femora and posterior 

 tibiss are yellow. I supposed, after examining it, that it was a distinct 

 species, yet after my return from the West, I am unable to distinguish 

 the alcoholic specimens from the (E. corrallipes. 



The following field-note may be of some value to other collectors : 

 As a provisional name I will call it (jE, paradoxa. 



Vertex rather prominent; a reddish tinge prevails on the lighter 

 parts of the whole insect; the lateral carinee of the pronotum are bor- 

 dered internally with a broad, whitish stripe ; the stripes along the dor- 

 sal angles of the elytra are quite distinct, and the dorsal margin with- 

 out spots; the wings are of an orange-red (sometimes cinnabar-red) at 

 the base ; the dark band crosses about two-thirds the distance from the 

 base to the extremity ; a dark stripe runs up the anterior border ; apex 

 transparent with dark nerves; the posterior femora inside, and the pos- 

 terior tibiae, bright yellow ; the exterior face of the femora crossed by 

 three irregular, oblique, dark bands ; antennae slightly enlarged, and 

 apparently flattened near the apex. Found from Ogden to Smithfield, 

 in Cache Valley. 



The dark bands across the femora, and the slightly flattened antennaf) 

 are not unusual in the other species. I met with a single specimen of 

 this red-winged kind in 1870, in Sweet Water Valley, Wyoming. 



Notwithstanding these wide variations I would not be surprised if 

 future investigations would show that not only these, but also (E. rtigosa, 

 Scudder, (if 1 know that species,*) are but varieties of the same species. 

 I see that Walker (Cat. Dermop. Salt.) gives Vancouver's Island as one 

 of the localities where GE. rugosa is found, and Indiana and Massachu- 

 setts as localities where (E. corrallipes is found, thus, as I suppose, 

 confounding the two. 



The (E. neglecta, Thos., which has a strong resemblance to the male 



*I have received but one specimen from New England, marked CE. rugosa, but 

 this specimen was certainly marked erroneously, being a variety of (S. verruoilata. 

 I have taken, at Washington, D. C, and in Illinois, specimens which correspond ex- 

 actly with Mr. Sciidder's description of CE. rugosa.
