 reason it is included here.]

The present genus is rather widely distributed, but the species are more frequently 

 met with along the sea-coast and the shores of the larger lakes northward. The only 

 representative is the following, which most assuredly crosses the Mexican border, 

 although no records or specimens are at hand to confirm the statement.

This insect occurs in both yellow- and red-winged forms, those with the red wings 

 being most prevalent in the south, while the yellow-winged individuals predominate 

 northward. 



[CONOZOA, Saussure. 



Conozoa, Saussure, Prodr. (Edip. p. 164 (1884) ; Scudder, Cat. Orthopt. U.S. p. 40 (1900).

Conozoa seems to be absent from the region covered by this work. At least, both 

 the collections studied and the references examined have failed to indicate that it is 

 found in Mexican territory. Notwithstanding this lack of evidence for its inclusion 

 among the fauna of Central America, the genus seems to be most abundantly represented 

 in the border region of the South-western United States and, in several instances, to 

 within a very few miles of Northern Mexico. There are at least eight so-called species 

 which will fall into this category : C. behrensi, C. rogenhoferi, and C. rebellis, Saussure, 

 and C. sulcifrons, C. acuminata, C. corrugata, C. picturata, and C. melleola, Scudder, 

 any, or all, of which may be looked for south of the Mexican frontier. 



They are very similar to some of the forms usually placed in the next genus.]
