HESPEROTETTIX. 315 



Ilab. North America, Southern States 1_5 . — Mexico 5 . 



The present insect is one of the most widely-distributed members of the genus. 

 It seems to be partial to several species of small yellow-flowered Composites as food- 

 plants, and occurs in numbers wherever these plants are found.

Hab. North America, Los Angeles Co., California *, Arizona 2 and New Mexico 

 (coll. L. Bruner). 



H. festivus will certainly be found further southward in Sonora and Chihuahua, 

 Mexico. 



4. Hesperotettix pratensis, Scudd.

Hab. North America, various localities from Manitoba to Texas and from the 

 Mississippi River to the Pacific Ocean l . — Mexico, Orizaba {coll. L. Bruner). 



The Mexican specimen is not quite typical, and may represent a closely allied 

 species, as suggested by Scudder. 



5. Hesperotettix speciosus, Scudd.

Hab. North America, various localities from the Dakotas to Northern Mexico 1-5 . — 

 Mexico, Northern Chihuahua (coll. L. Bruner). 



The present species is somewhat a.berrant in its general structure, and varies greatly 

 in size, the southern specimens being much larger than those from its northern range. 



Another species, H. gacificus, Scudder, which is common about Los Angeles, 

 California, is also likely to occur in Lower California and the northern part of Sonora, 

 although no records of such distribution of the insect are at hand.
