broader shoulders and face, a more sloping pronotum with 
higher median carina opposite the shoulders, and more sinuate 
facial profile. A female of this form labeled from the alpine 
region of the White Mountains is in the Scudder collection. I 
have also seen three specimens, which probably belong to this 
form, taken in July at Moosehead Lake (Capens, and Sugar Id.), 
Me., by Mr. C. W. Johnson.

The distinguishing characters of this species have already been 
stated in the key. Long-winged and short-winged examples 
are about equally numerous. The name triangularis 
was applied by Scudder to the short-winged form of 
this species (Boston Journ. Nat. Hist., vol. 7, p. 475, 
1862). 
Color: generally dark brown or graj'ish, either 
uniform or varied above with pale brown or white. 
The pattern is exceedingly variable. There is often 
a pair of triangular blackish spots on the disk of the 
Ornate Pygmy pronotum oppositc the base of the hind femora, and 
Locust, Aery- elougatc or cresccutic spots in front of them, on a 
dium ornatum. i • i i i 
(After Lugger.) palcr grouud; sometnnes a broad transverse pale 
band covers the front of the shoulders, giving a 
'collared' appearance; sometimes the disk is dark, with narrow 
white lines bordering the lateral carinae along the humeral 
angles; or the anterior median portion and the hind process may 
be pale, with the shoulders marked with intricate patterns of 
blackish.
