median tibiae nearly half again as long as the femora. Caudal 

 femora about a third again as long as the body, moderately inflated 

 in the proximal three-fifths, genicular lobes unispinose; caudal 

 tibiae surpassing the femora by about the length of the pronotum. 



Allotype: 9 ; Laguna del Gato, three miles west of Sam Fordyce, 

 Hidalgo County, Texas. Elevation 175-200 feet. August 6, 1912.

Description of Allotype. — Characters not specifically mentioned are 

 not markedly different from the male sex. 



Size medium; form moderately robust. Pronotum much less 

 compressed, the median width of the disk of the pronotum contained 

 less than three times in the length of the same. Tegmina much 

 broader than the apparent length, apices hardly surpassing the 

 margin of the metanotum, the distal margin rotundato-truncate, the 

 interspace between the tegmina not more than half the width of 

 a single tegmen; venation irregular. Cerci very short, conoid; 

 ovipositor nearly equal to the length of the head and pronotum 

 together, tapering in the proximal two-thirds, the proximal 

 depth slightly more than a third of the length, moderately 



arcuate, ventral margin appreci- 

 ably flattened for a portion of 

 its length, dorsal margin more 

 arcuate distad than proximad, 

 apical margins proper slightly 

 more acute than a rectangle, 

 armed on the distal third of the

(X i ) ventral margm strongly arcuate 



distad, armed with nine spines, 

 the proximal several of which are smaller than the others, the 

 distal ones distinctly recurved; subgenital plate brief, strongly 

 transverse, distal margin obtusely brace-shaped (■ — . — •) emarginate. 

 Cephalic femora slightly exceeding the combined length of the head, 

 pronotum and tegmina, slightly more robust than in the male. 

 Median femora as robust as the cephalic pair. Caudal femora a 

 fourth again as long as the body (exclusive of the ovipositor) , appre- 

 ciably more robust than in the male, the proximal dilation slightly 

 more extensive. 



Paratypic Series. — A paratypic series of five males and eight females 

 from Laguna del Gato has been selected, the measurements of the 

 same being given below.
