These specimens agree fully with the description and figures of this 

 species, which has been previously recorded only from northern and 

 w^estern Arizona. There is considerable variation in size, 20 to 24 

 millimeters in the length of body of the & and 24 to 28.5 in the 9 . 

 The color of the caudal tibise varies from pale glaucous to very decided 

 blue, pale laterad, while the general color is more besprinkled with 

 fine spots of umber on the dorsum in some specimens than in others. 



This species was found almost invariably among the sage. The 

 color of the insects blends so exactly with the sage-brush that when 

 at rest they are difficult to find. I noticed that the insects almost 

 always sought refuge in the sage instead of on the ground. On and 

 about Ensign Peak the species was plentiful.

This large series presents a considerable amount of variation in size 

 and color. The smallest d^ measures 17.5 millimeters in the length of 

 body, the largest 22 ; the smallest 9 20, the largest 26. The individuals 

 with the pronotum with a dark median bar superficially much resemble 

 M. packardii. The general coloration is quite dark in some individuals 

 and very light in others, the latter type having all the normal darker 

 markings very weak, while some few specimens have the dorsum of 

 the head and pronotum suffused with purplish red. The Roggen 

 individuals are more grayish than any others examined. Of the large 

 series examined all but two have red caudal tibiae, the color usually 

 pale coral red. The other two specimens, a pair from Knob Hill, 

 have glaucous tibise. The authors are much inclined toward the 

 opinion recently expressed by Gillette,^^ to the effect that M. coccineipes 

 represents merely a red-legged form of M. angustipennis. 



This was one. of the species which made up the vast swarms of 

 Orthoptera everywhere to be found in the prairie grasses outside of 

 Colorado Springs. So great was the number of grasshoppers that it 

 was almost impossible to follow any one interesting specimen when 

 seen. All of the specimens of this species were taken by sweeping the 

 grass.
