Grasshoppers of Kansas. 37 



but not elevated, the -apical face with no subapical tubercle; furcula 

 delicately developed; cerci compressed styliform, rather small; ovipositor 

 of female normally exserted. 



This genus is very closely related to Melanoplus, from which it is to 

 be distinguished by its large, tumid head and subsellate equal pronotum, 

 as well as by its substyliform cerci. The neuration of the tegmina, when 

 the latter are developed, also differs to a certain degree, pointed out in 

 the description. — 1. c. Scudder. 



Phcetaliotes nebrascensis Thos. 

 Varieties nebrascensis and volucris. 

 Head flaveo-testaceous to rather ferruginous, especially on the top. The 

 interspace between the eyes of the female is hardly three times as wide 

 as the first antennal joint, in some cases not more than twice as wide. 

 The fastigium is distinctly though not deeply sulcate in most of the 

 specimens ; frontal costa nearly reaching the clypeus, about half again as 

 broad below the ocellus than above in the male, and twice as broad in the 

 female, narrowest just between the antenna?. Antennae ferrugino-testa- 

 ceous, somewhat infuscated at the tip. Disk of pronotum varies from 

 testaceous to bright ferruginous; median carina sharp, subequal, more 

 distinct on the metazona than on the prozona in some specimens; prozona 

 distinctly longitudinal in the male but subquadrate in the female. Pro- 

 sternal spine rather retrorse.

Of this species both varieties are quite common and have been found in 

 practically all parts of the state. The short-winged variety, P. nebras- 

 censis, is more common than the long-winged variety, nebrascensis 

 volucris. Neither one of these varieties has ever been found in large 

 enough numbers to be of any economic importance. 



FREAK SPECIMENS IN SPECIES OF MELANOPLI. 



In going over a lot of duplicate material, one always finds variations, 

 in one form or other, in specimens of the same species. Usually these 

 variations are slight and not so noticeable in superficial observations; 

 however, once in a while there occur variations or freak specimens which 

 are very readily noticeable, and interesting to study.
