MICROTES KUBILA Scudder. 



This species is a synonjmi of the earher described Sciriettica occi- 

 dentalis of Brunei*. The genus seems amply distinct, and thus the •: 

 species is to be known as Microtes occidentalis Bruner. 



The Genus Alpha Brunner. 



The name Cordillacris has been substituted for Brunner's genus 

 Alpha by Mr. Rehn ^ on the grounds of preoccupation. In proposing 

 Cordillacris Mr. Rehn gives the original reference to AljjJia as ''Smiths. 

 Misc. CoU., XIV, p. 121 (1875)." The volume in this reference 

 should be CCLIV and the page is 117. But the first use of Alpha, 

 however, was nearly a quarter of a century earher when it was used 

 in three different senses by Saussure in his "Etudes Fam. Vesp., vol. 

 ii, p. 167 (1853)," and in the same work, vol. 3, pp. 128, 137, and 

 160 (1854). But I fail to find that Saussure used this name other 

 than as a division between the species and genus. As such groups 

 or divisional names have no place in nomenclature ^ they do not 

 preoccupy and thus Alpha seems to have been available as a generic 

 name when erected in the Orthoptera by Brunner in 1893. 



The Generic name Macneillia of Scudder. 



This generic name was proposed to replace the genus Pedeticum of 

 McNeill on the assumption that that name was preoccupied by the 

 generic name Pedeticus of Laporte in the Hemiptera. But by the rule 

 of identical speUing Pedeticus does not preoccupy Pedeticum and thus 

 Scudder's name Macneillia was not needed. 



AEOLOPLIDES, ne^A/' genus. 



The t3"pe species of the genus Aeoloplus Scudder is Caloptenus 

 regalis by original designation. But regalis is now known to be a 

 species of Melanopliis and thus Aeoloplus, which follows its type spe- 

 cies, is a synonym of Melanoplus. The species formerly included in 

 Aeoloplus are thus left without a generic name, and for them the 

 genus Aeoloplides is here proposed, ^vith the Pezotettix chenopodii 

 of Bruner as the designated type. 



The Genus Boopedon of Thomas. 



Ket/ to Species. 



1. Pi'tiicipal sulcus of the proiiotum not far behind the middle in either sex; males 



with elytra two or more times as long as the pronotum 2. 



Principal sulcus of the pronotum, especially in the male, generally much beliind 

 the middle; males with elytra less than two times as long as the pronotum. . . .4.
