REHN AND HEBARD 51 



lating field quite ample, rather bullate, in area surpassing that of the dorsum 

 of the head and pronotum, stridulating vein straight, transverse, crassate, 

 speculum broader than usual in the genus. Wings surpassing the tegmina by 

 nearly the pronotal length. Cerci robust, rather short, median tooth directed 

 proximo-mesad and subdepressed, shaft of cercus with a sinuate medio-longi- 

 tudinal carination on the dorsal surface, the distal section subacuminate when 

 seen from the dorsum, tapering regularly when seen from the side ; subgenital 

 plate moderately produced, distal margin obtuse-angulate emarginate, styles 

 brief, articulate, a moderately distinct and complete medio-longitudinal and 

 distinct lateral carinae indicated. Caudal femora about four-fifths the length 

 of the body, moderately inflateii proximad, ventral margins unspined, genicular 

 lobes bispinose. 



Allotype. — 9 ; Rosenberg, Fort Bend County, Texas. July 25 

 and 26, 1912. (Hebard.) [Hebard Collection.] 



Description of Allotijpe. — The features here given are those of difference from 

 the male sex. Size smaller than in the male sex; form more slender. Prono- 

 tum not at all sellate, when seen from the lateral aspect the dorsal outline is 

 straight, greatest width of raetazona about two-thirds the length of the whole 

 pronotum; length of the metazona almost one-half the entire pronotal length, 

 transverse sulcus well indicated on the dorsum but by no means so impressed 

 as in the male; lateral shoulders not appreciably indicated anywhere. Teg- 

 mina slightly surpassing the apices of the caudal femora. Wings surpassing 

 the tips of the tegmina by several millimeters. Ovipositor sUghtly more than 

 half the length of the caudal femora, rather strongly falcate, comparatively 

 bi'oad, apex acute, ventral margin of ovipositor appreciably but very finely 

 serrulate on distal half; subgenital plate of female shallowly and narrowly 

 emarginate disto-mesad. 



Paratypic Series. — We have selected as paratypes two males 

 from Galveston, Texas, bearing the same data as the type, one 

 male from Rosenberg, Texas, bearing the same data as the allo- 

 type and six males from Gregory, San Patricio County, Texas, 

 July 30, 1912 (Hebard).
