30 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.49. 



States NationeJ Museum with specimens from Arizona, identical with 

 the form described recently by Bruner as B.fuscum. Also, from the 

 original description of B. nigrum of Thomas and his subsequent 

 quoting of that species in the synonymy of what he took for nuhilum 

 Say but which was, as shown above, the B. fuscum of Bruner, it is 

 evident that this was also the same species and, being the older, 

 should supplant Bruner's name. 



MELANOPLUS MUTATUS, new name. 



Melanoplus minor of Scudder, described as Pezotettix minor in 

 1875, is a primary homonym of Pezotettix minor Walker, an African 

 grasshopper described in 1870.^ Under all recent codes of nomen- 

 clature Scudder's name must fall and for it the new name Melanoflus 

 muiatus is here proposed. 



MELANOPLUS MARGINATUS Scudder. 



Melanoplus marginatus pauper Scudder. 



The brachypterous specimens of Melanoplus marginatus constitute 

 the typical form, being the only ones mentioned in the original 

 description. Scudder's varietal name pauper therefore falls as a 

 synonym of the typical nsune rnarginatus, according to paragraph 31 

 of Entomological Code. The long-winged form is properly called 

 amplus. 



MELANOPLUS FEMUR-RUBRUM DeGeer. 

 Melanoplus coloradus Caudell. 



Melanoplus coloradus Caudell is but a minor variety oifemur-ruhrum, 

 the only constant differentiating character being the fercula of the 

 male surpassing more or less the mesial interruption of the median 

 sulcus of the supraanal plate. This character is of scarcely sufficient 

 value to hold a name, and this species is therefore sunk as a sjnionym 

 of femur-rubrum. 



MELANOPLUS DEVASTATOR Scudder. 



Melanoplus devastator typicalis Scudder. 



Tills varietal name should be di'opped and the name devastator 

 alone used according to paragraph 31 of the Entomological Code. 



MELANOPLUS DEVASTATOR Scudder. 



Melanoplus devastator offinis Scudder. 



The name affinis as here used is invalidated by the earUer use as a 

 specific name by the same author. Paragraph 37 of Entomological 

 Code applies here. But the characters separating this variety from 

 the typical form are of such minor importance that the name may
