This species is very common in Kansas and is one of the first to ma- 

 ture in spring. Fully developed specimens have been found the first of 

 June. There are, very probably, two generations a year. Although very 

 common and at times quite numerous, we have never observed them in 

 large enough numbers to be of any great economic importance. They 

 are found along the roadsides and pastures as well as in cultivated 

 fields. The length of the tegmina varies from very short to ones that 

 extend the entire length of the abdomen, or even beyond it. We have 

 observed the females oviposit from the middle of June till late in Sep- 

 tember, and even in October. 



Found in all counties where collecting has been done. 



Melanoplus discolor Scudd. 



The general color is brownish fuscous above and yellowish brown be- 

 low. Antennas ferruginous, somewhat infuscated at the tip. A very 

 broad piceous belt, which widens posteriorly, extends from behind the 

 eyes across the prozona. Tegmina are darker on the lateral field than on 

 the dorsal. 



Vertex of head considerably elevated above the pronotum of the male, 

 but not elevated at all in the female. Frontal costa subequal, flat above 

 ocellus, slightly sulcate at and below ocellus. Median carina distinct, 

 cut only by the principal sulcus. Prosternal spine cylindrical, blunt and 

 retrorse. Supra-anal plate of male triangular, with median sulcus ex- 

 tending half the length of the plate. Furcula very small approximate 

 lobes, the lobes shorter than the last dorsal segment from which it 

 springs. Hind femora trifasciate above with blackish, the basal fascia- 

 tion taking the form of a dark spot. Hind tibia bright red with black- 

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