Outside of the Arkansas valley a specimen was taken at Wray 
(Ball). We have taken this species at Pueblo, Nepesta, 
Rockyford, Las Animas, Lamar and Wray. 
All the males are black with hind tibiae more or less red 
and with elytra nearly attaining the tip of the abdomen. In 
length they vary between 20 mm. and 27 mm. (52 specimens). 
Out of 30 females, 26 are dusky and greenish, marked with 
yellow, and four are black. They vary in length between 31 
mm. and 44 mm., and, with one exception, the wings are 
short, about 12 111m. long. The single long-winged female 
has elytra surpassing the tip of the abdomen. 
flavofasciatum Thos. Probably the light-colored form of the- preced¬ 
ing species. 
STIRAPLEURA Scudder. 
decussata Scudd. Occurs across the plains and in the mountains to 
an altitude of 8,000 feet. Quite abundant in the vicinity of 
Ft. Collins. Occurs commonly in open grassy areas; food- 
plants not known. 
Taken at Ft. Collins, Laporte, North Park, Denver, Col¬ 
orado Springs, Pueblo, Rockyford, Lamar, Canon City, Trini¬ 
dad, Antonito, Gunnison, Claremont, Elbert and Dunkley.

deorum Scudd. What I take to be typical examples of this species 
in the collection are from Colorado Springs (Cockerell), Pueblo 
and Boulder, though others nearly as typical come from 
Rockyford, Ft. Collins and other points. This species seems 
to me to grade impereeptably into scudderi . 
occidental^ Brun. (See diseription following this article). 
A west slope species, the specimens in the College collec¬ 
tion coming from Antonito, Durango, Grand Junction, Glen- 
wood Springs and Delta. Dates—Aug. 5th to Sept. 23rd. 
scudderi Brun. A common species upon the plains near the foothills, 
particularly in the northern portion of the State. It extends 
to the eastern border of Colorado and to an altitude of 6,000 
feet at least in the foothills. Adults begin to appear at Ft. 
Collins about June 20th and we have taken them as late as 
Sept. 28th. Adults were mating freely July 30th, 1902. (Ball.) 
Specimens taken at Ft. Collins, Laporte, Dutch George’s, 
Livermore, Greeley, Ft. Morgan, Snyder, Merino, Wray, Ster¬ 
ling, Julesburg, Boulder, Palmer Lake, Pueblo, Rockyford, 
Las Animas and Lamar. This species seems to me to be a 
unicolorous variety of deorum.
