This insect is certainly distributed further to the westward, so as to cross the Rio 

 Grande into Mexican territory. It is common in weed-patches, where it occurs most 

 frequently on different species of Helianthus.

While this form, or species, is found throughout the greater part of Texas, it seems 

 to be most common northward. It may also reach Mexican territory.]

Hesperotettix is a well-defined genus, the representatives of which are fairly evenly 

 dispersed over North America between 18° and 54° N. lat. The species are, for the 

 most part, fully winged and of a prevailing green or greenish colour. They were 

 tabulated by Scudder {loo. cit), and more recently by the present writer (Bulletin 

 Colorado Exp. Station, No. 94, pp. 62, 63).
