83. Mtelanoplus Packard!! Scudd. — Barber Co. and Garden City (Cra- 

 gin). 



This is the locust which was described as Caloptenus fasciatus, Scudd., 

 but afterwards changed to the above name by the same author to avoid 

 conflicting with the Gal. fasciatus of Walker, a species found at St. Mar- 

 tin's Falls, Hudson Bay. This is an upland insect and may be met with 

 throughout the western half of the United States and British America at 

 all suitable localities. It bears some resmblance to M. bivittatus Say, but 

 never leaves the open country for timbered or \oyr localities where the veg- 

 etation is rank, as does this and several of our larger species of this genus. 



84. Mtelanoplus bivittatus Say. — Labette Co. (Newlon); Topeka, Gar- 

 den City and Barber Co. (Cragin). 



This is the common two-striped locust of our meadows and fields, and 

 usually occurs where vegetation is rankest. It is found from ocean to 

 ocean, and from the Gulf of Mexico northward to the Saskatchewan River 

 in the British possessions. Mr. Scudder says that the variety with red 

 posterior tibiae is the Caloptenus femoratus of Burmeister, and considers 

 it a distinct species. 



85. Melanoplus differentialis Thos. — Labette Co. (Newlon); Topeka, 

 Garden City and Barber Co. (Cragin.) 



This is our largest species of the genus and occurs in suitable localities 

 throughout the central and eastern portions of the United States, where it 

 also frequents low grounds among the rankest of vegetation. M. robustus 

 and M.ponderosus are allied species which occur in Texas. 



86. Melanoplus Turnbullii Thos. — Garden City (Cragin). 



This species is one of the few that is partial to some particular food-plant 

 or set of food-plants, and in this instance it is the members of the Chen- 

 opodiacese, and especially the different kinds of pigweeds. It occurs at 

 various points throughout Arizona, New Mexico, Colorado, Kansas, Wyo- 

 ming and Montana. Scudder's Pezotettix plagosus is a synonym of this 

 insect, at least this is what Mr. Scudder himself states. 



87. Tettix granulata Say. — Topeka (Cragin). 



The small Grouse Locusts, of which there are quite a number of species 

 in the United States, are very difficult to identify, and appear to vary so 

 much that I have never done much toward trying to separate the material 

 in my collection. They all winter over as larva?, pupse or mature insects, 

 and are to be found on sunny hill slopes throughout winter. Their favor- 

 ite haunts are the edges of groves and the margins of streams. Closely 

 browsed pastures are also frequented by them during the warm days of late 

 fall and early spring, where they appear to congregate for sunning them- 

 selves. They never become so numerous as to injure crops, and but seldom 

 enter cultivated grounds, except where these are low and damp, or lie along- 

 side of meadows or groves near streams. 



88. Tettigidea polyiiiorpha Burm. — Barber Co. (Cragin). 



The members of this genus, like those of the preceding and also those 

 of BatracJiidea, are found in like localities with them, and are also similar 

 in general appearance and habits.
