 Melanoplus packardii Scudder. 



This species varies considerably in the general ground colors, varying 

 from real light yellow to dark brownish fuscous. Medio-dorsal stripe 

 varies both in intensity of color and in breadth; in color from testaceous 

 to blackish, in width from a rather narrow stripe to one-half the width of 

 the prozona. In the blue-legged forms the stripe often is darker and more 

 clearly defined than in those with red hind tibia, and shows a stronger 

 tendency to taper to a point on the metazona. Frontal costa slightly 

 sulcate at and below the ocellus; antennae yellowish brown, infuscated at 

 the tip; tegmina extending beyond the hind femora 2 to 5 mm. Hind 

 femora bifasciate to trifasciate above; hind tibia blue or red with black- 

 tipped spines ten to twelve in number in the outer series.

Localities. This species is very common in the state, and may be 

 found among practically all the cultivated fields and crops as well as pas- 

 tures and meadows. 



Melanoplus fcedus Scudder. 



The general color is "dirty cinereous above and dingy clay-yellow be- 

 low." Quite similar in size and structure to M. packardii, but with red 

 hind tibia. Frontal costa enlarging slightly anteriorly, failing to reach 

 the clypeus. Tegmina extending beyond the abdomen of the male by at 

 least 2 or 3 mm. Extremity of male abdomen somewhat recurved, clavate. 

 Hind tibia dull red with a blackish basal annulus; spines black, ten to 

 thirteen in number in the outer series.
