The present species differs from its more western race, 7. elegans 

 consuetipes, in being less slender in structure and the marginal 

 field of the tegmina narrows more abruptly distad from the proxi- 

 mal third, •'^- moreover typical elegans shows a herring-bone pattern 

 of greater or less intensity on the tegmina, while in the western geo- 

 graphic race these organs are immaculate or nearly so. From /. co- 

 villeae, the species showing nearest relationship, elegans may be 

 easily separated by the very different pronotum, less abruptly nar- 

 rowing marginal field of the tegmina and striking differences both in 

 coloration and color pattern. 



Described from three females from two adjacent localities in 

 central southern New Mexico. 



Single Type here chosen. — 9 ; Mesilla, New Mexico. Elevation 

 3865 feet. June 30, 1897. (A. P. Morse.) [Scudder Collection.] 



Description of Type. — Size medium for the genus, form rather slender- 

 Head with greatest width contained about one and three-fifths times in 

 greatest depth; occiput rounded, slightly declivent toward fastigium, the 

 latter narrow, compressed, subequal, with an appreciable medio-longitu- 

 dinal sulcus on the dorsal surface, lateral margins roundly elevated, fasti- 

 gium in contact with frontal fastigium for full length of both, widening 

 slightly more than in /. toltcca above this sulcus; eyes large, prominent, 

 ovate in outline, equalling in length the infra-ocular portion of the genae. 

 Pronotum with dorsal length about one and three-tenths the greatest (caudal) 

 dorsal width, dorsum of pronotum deplanate, slightly elevated caudad; 



" The figure which accompanies the original description is poorly drawn 

 and fails completely to show this character and the tegmen as it really is.
