Schistocerca rubiginosa Harris. 



Only two specimens of this species have been seen, both 

 captured in the southeastern part of the state among the 

 wooded bluffs of the Mississippi River. It is light rust-red, 

 rather uniform. Elytra opaque, rather paler on the over-

 with small, darker colored spots. Wings transparent, yel- 

 lowish at base, slightly reddish tow^ard the tip; veins black-

 black spot on the side. Spines of the tibi« whitish, tipped

 a slight vermilion tint. A yellow stripe extends from the
