length of the caudal femora; apex at humeral angle very broadly 

 and roundly obtuse-angulate, distal margin of dorsal field almost 

 transverse, very broadly arcuato-truncate, sutural margin passes 

 into distal margin with a distinct, rather sharply rounded angulation 

 at an angle of slightly more than ninety degrees; intermediate 

 channel not conspicuously depressed and forming part of the dorsal 

 field, this field rounding very slightly; longitudinal veins few but 

 conspicuous, cross-veinlets^^ exceedingly faint. Wings absent. Ovi- 

 positor^*^ a little more than two-thirds as long as the caudal femur,

distinctly though feebly arcuate, form and armament much as in 

 cubensis. Caudal femora and spines of caudal tibiae much as in that 

 species. 



We here select as allotype, a male from Las Vegas, Nevada, taken 

 Sept. 2, 1909, by Rehn and Hebard, and in the Hebard Collection. 



Description of Allotype. — Size smaller than female, proportions 

 much the same. The tegmina are translucent and when in repose 

 the dorsal fields are hemi-elliptical in outline. Wrings absent.

55 These cross-veinlets are so faint in some specimens as to be scarcely visible 

 under a Zeiss binocular. 



56 As the ovipositor of the paratype before us is broken, we have drawn up this 

 portion of the description from the type.
