406 PROCEEDINGS OF THE ACADEMY OF [Sept., 



similar in coloration to individuals from eastern Colorado and Nebraska. 

 The coloration is decidedly brown, sometimes gray brownish, and little 

 yellow or clear gray is apparent. The head and pronotum are sprinkled 

 with fine umber dots and the tegmina have distinct quadrate macula- 

 tions. The length of the body ranges from 17.5 to 19.5 millimeters. 



All of the specimens of this species were found in the valley of the 

 Grand river. Those taken at Grand Junction were found on silt 

 near the river, where very little vegetation was to be seen. The 

 insect's coloration was extremely protective and the species relied 

 almost entirely on its wings for locomotory power.

This series shows considerable variation in size and color, the latter 

 chiefly in varying intensity of the pattern. 



This species was found in the same situations as M. occidentalis, but 

 in much greater numbers. 

 Melanoplus sanguineus Bruner. 



Garden of the Gods, Colorado, Aug. 17, 1 c?, 1 9 . 



This striking and beautiful species was recently described from 

 Lamar and Las Animas, in the prairie section of the Arkansas valley, 

 Colorado. This record shows it ascends well into the foothills. 



The coloration of the caudal femora and tibiae is very striking and 

 serves to readily identify the species. The female specimen in hand has 

 the head, caudal section of the disk of the pronotum and the dorsal 

 face of the caudal femora somewhat suffused with greenish. 



The specimens were taken in the high grass of a meadow at the 

 western entrance to the Garden of the Gods.
