The author's description is here given : 



" Nearly uniform dull brownish testaceous, the hind femora feebly 

 infuscated apically. Head full, the face somewhat ferruginous and the 

 genae with fuscous blotches, the fastigium rather prominent, rounded ; 

 antennae very slender, about half as long again as the body, testaceous. 

 Pronotum well rounded, equally arched in front and behind, without 

 lateral or median carinas, the front margin feebly convex, the hind border 

 truncate, but laterally rounded ; lateral lobes obliquely deflexed, well 

 rounded beneath, the oblique posterior margin with a distinct though 

 slight sinus. Tegmina aborted. Legs rather long and slender, the fore 

 tibiae with three spines above on outer margin. Ovipositor more than 

 two-thirds as long as the hind femora, distinctly arcuate, moderately 

 slender, faintly tapering, apically acuminate, castaneous, the apical 

 margins darker. 



" Length of body, 25 mm. ; pronotum, 8 mm. ; fore femora, 7 mm. ; 

 hind femora, 21 mm.; ovipositor, 16.5 mm. 



"One female. Arizona, U. S. National Museum." (Type No. 5736.) 



It is pointed out by the describer that this, being the species on 

 which the genus was established, is the type of the genus, even though 

 another species, E. Scudderi, Cock., had been previously described. 

 This view may be questioned according to the latest published laws on 

 this subject, and the genus previous to the publication of Cockerell's 

 species in 1898 was certainly invalid, being based on an undescribed 

 species. However, the circumstances seem to justify the retention of 

 unicolor as the type of Eremopedes, Scudd.
