bi-oad. The neuration does not show clearly ; there is no diminution in 

 breadth before the rapidly rounded apex ; the teg-mina appear to have been 

 clear and light colored on the disk but broadly obscured at base, at the 

 margins, and along the principal veins, and on the apical third broadly 

 margined throughout witlr brownish fuliginous, fading gradually basally. 



Length of head and thorax, 3.5""" ; tegniina, 9""" ; breadth of latter, 

 2.75™"'. 



Green River, Wyoming. One specimen, Nos. 34 and 35, Prof L. A

2. Tettigonia priscotincta. 



PI. 19, Fig. 9. 



Head, as viewed from above, rounded, subtriangular, the front strongly 

 convex, the ocelli situated on the vertex, the surface of the head and thorax 

 iniiform, the scutellum roundly angulated behind. Tegniina barely reach- 

 ing the tip of the abdomen, pale with bold dark markings, as follows : A 

 broad subequal stripe follows the outer edge of the sutura clavi to the mid- 

 dle of the wing, where it unites faintly with a narrow stripe which has fol- 

 lowed the commissural margin to the tip of the sutura clavi and distinctly 

 and broadly with a small round spot on the middle of the costal margin ; 

 the markings on the outer half of the wing are somewhat irregular, but may 

 best be described as taking the form of a broad and rude X, one bar run- 

 ning from the center of the wing, just out of contact with the basal mark- 

 ings, to the lower apex of the wing where the margin is clouded with fulig- 

 inous, the other crossing the whole wing obliquely and recurved on the 

 costal margin. I do not find any existing species with markings at all sim- 

 ilar, the nearest approach being that of T. bella Walker from Silhet. 



Length of body, 7.75""°' ; breadth of head, 2°^"' ; of abdomen, 2 5""" ; 

 length of tegmina, 6™™ ; breadth, 2™™. 



Florissant. Two specimens, Nos. 7628, 12996. 



3. Tettigonia pkiscovakiegata. 



A single specimen is preserved, of which only one of the tegmina may 

 certainly be claimed for the species. This is very long and slender, three 

 and a lialf times longer than broad, in the apical fifth tapering rapidly to 

 the rounded tip which is in the middle of the inner half of the tegmina ; it 

 is [)ale with blackish brown markings, which consist, first, of a narrow mar-
