MELANOPLUS. 319 



ivory-white apically ; hind tibise on their immediate base ivory-white, for the rest deep bluish-glaucous, 

 the spines white, black-tipped, the tarsi largely ivory-white. 

 Length of body, $ , 30 ; of pronotum 8, of tegmina 24, of hind femora 16, of antennae 10 millim. 



Hah. Mexico, Colonia Garcia, Chihuahua (C. H. T. Townsend). 



One female. There is another female specimen of the genus Melanoplus at hand 

 which comes rather close to the one just described, but it is a little more slender in 

 form and lacks the green tinge of the head and pronotum of M. picturatus, while the 

 sulci are not infuscated or the hind femora so vividly coloured. Possibly the insect 

 referred to by Rehn (Proc. Acad. Nat. Sci. Philad. 1907, p. 55) as M. regalis, Dodge, 

 belongs to the present species.

This insect is very common along the banks of the Rio Grande and its lower 

 tributaries, where it occurs, according to Prof. T. D. A. Cockerell, on Pluchea borealis 

 as a food-plant.

Doubtless reaches Mexican territory, the same remark applying to the following 

 species.

This insect is unknown to the present writer, but, if distinct, comes close to 

 M. bowditchi and its allies.]
