REHN AND HEBARD 47 



TTjpe. — cf ; San Antonio, Bexar County, Texas. August 15 to 

 16, 1912. (Rehn and Hebard.) [Hebard Collection Type Xo. 

 164.] 



Desa-iption of Type. — Size medium (for the genus); form robust; surface 

 moderately polished. Head with the fastigium gently ascending from the level 

 of the occiput, the width of fastigium faintly greater than width of proximal 

 antennal joint, the margins when seen from the cephalic aspect regularly but not 

 strongW converging ventrad; eyes moderately prominent, faintly ovate in basal 

 outhne; antennaewhen in perfect condition nearly four times as long as the body. 

 Pronotum very faintly sellate, this being due to the gently ascending character 

 of the metazona, the line of the prozona nearly straight when seen from the side; 

 greatest caudal width of the metazona contained one and one-third times in 

 the entire pronotal length; cephaUc margin subtruncate, caudal margin gently 

 arcuate, metazona about two-thirds the length of the prozona, well separated 

 from the latter by an appreciable transverse sulcus; lateral lobes of pronotum 

 with their greatest dorsal length surpassing their depth, cephaUc margin 

 oblique subtruncate, ventro-cephalic angle very broadly rounded, ventral 

 margin strongly oblique truncate, ventro-caudal angle rectangulate, caudal 

 margin gently arcuate, humeral sinus hardly indicated, convex callosity subo- 

 vate, with pomted extremities and moderately broad. Tegmina not reaching 

 the tips of the caudal femora, in general form resembUng those of vulgare; 

 stridulating area subequal in extent to the dorsum of the pronotum, stridulat- 

 ing vein transverse, robust. Wings very slightly surpassing the tegmina. 

 Disto-dorsat abdominal segment wath the median emargination U-shaped, 

 relatively broad and deep, the flanking processes considerably produced and 

 recurved ventrad; cerci rather heavy, proximal half straight, rounded in form, 

 subcolumnar, median tooth aciculate, placed immediately distad of the middle, 

 elongate, but Httle shorter than the length of the entire shaft of the cercus, 

 directed inwards and gently falcate distad, subdepressed proximad, distal 

 portion of the shaft of the cercus tapering to a blunt point, depressed; sub- 

 genital plate with distal margin subrectangularly emarginate, styles short, 

 subrobust, lateral margins regularly converging to the bases of the styles, 

 venter of plate with distinct paired ridge-Kke carinae extending cephalad from 

 the base of the styles, a much fainter median carina also present. Caudal 

 femora robust, distal portion rather slender, ven tro-external margin armed 

 distad with three to four spines, ventro-internal margin unarmed, genicular 

 lobes bispinose. 



Allotype. — 9 ; Same data as type. 



Description of Allotype. — Differing from the description of the type in the 

 following respects. Dorsal line of pronotum nearly straight when seen from 

 the side, not ascending on the metazona; greatest caudal width of metazona 

 contained one and one-half times in entire pronotal length. Ovipositor slightly 

 less than half the length of the caudal femora, regularly falcate, rather broad, 

 ventral margin very faintly serrulate distad, subgenital plate of the form usual 

 m the genus.
