Size rather small and forDi comparatively slender. Head mod- 

 erately large, slightly tumid, both on the occiput and gense ; vertex 

 decllnate, broad and flattened ; eyes oval. Pronotum about once 

 and a half as broad as long, emarginate anteriorly, the posterior 

 border slightly arcuate; lateral margins tumid, surface obscurely 

 punctulate ; lateral lobes shallow, the anterior angle obtuse, the 

 lower margin sloping upward and backward to the rounded poste- 

 rior angle. Tegmina moderately long, not much more than twice as 

 long as the pronotum, the mediastinal view with three branches. 

 Anterior and median limbs rather slight, compressed. Posterior 

 femora moderately heavy, rather attenuate apically; tibise two- 

 thirds as long as the femora, armed with 6-8 spines on each margin, 

 the upper inner calcar distinctly shorter than the intermediate 

 one. Ovipositor reaching to the apex of the outstretched meta- 

 tarsus. 



General color blackish-brown, the infraocular portion of the 

 gense and the humeral angle of the tegmina ochraceous, the veins 

 of the mediastinal area being of the same color. Posterior femora 

 orange-red, becoming dull-brownish posteriorly.

Miogryllus lineatus (Scudder)? 



One immature male. 



Alamogordo, Otero county, N. M. April 25, 1902. 



This specimen is very questionably assigned to this species, and a 

 number of characters show considerable difference from the descrip- 

 tion. Considering the apparently immature condition of the speci- 

 men I think this the best course to adopt. 



Subfamily (Ecanthmse. 

 (Ecanthus sp. 



One immature female. 



Alamogordo, Otero county, N. M. June 9, 1902. 



This species is in all probability undescribed and shows closest 

 relationship with (E. niveus and angustipennis.
