REVISION OF ELEODIINI BLAISDELL. 4S 



very sparsely punctate and setose apically, setse moderately short. 

 Sinus triangular, membrane slightly setose at bottom. 



Female. — Genital segment quadrate, valves refiexed at the sides, 

 setose, glabrous and shining. 



Valvula (Plate 4, fig. 26). — Dorsal plate oblong, explanate exter- 

 nally and slightly defiexed, internally refiexed and impunctate in 

 apical half; surface convex externally, very sparsely punctate, punc- 

 tures denser on convexity, each with a long seta ; external margin 

 straight ; angle rectangular and prominent, sometimes feebly rounded, 

 with a few moderately long setae; apical margin squarely truncate to 

 moderately and arcuately produced in outer half, more or less sin- 

 uate over the appendage ; internal margin more or less arcuate. Apex 

 short, triangular and acute, set with a few moderately long setse. 



Apjyendage (cercopod) short and moderate in size, conical or feebly 

 depressed, bearing moderately long setse. 



Basal 'prommences not evident. 



Superior pudendal meTnhrane feebly and distinctly longitudinally 

 rugulose, reaching to about the middle of the dorsal plate. 



Ventrolateral surface moderately convex, scarcely concave before 

 the apex ; submarginal groove broad and shallow beneath the ex- 

 planate external border of dorsal plate ; surface finely punctate and 

 setose, setse minute. The internal borders of the valvulse are con- 

 tiguous in basal sixth; genital fissure fusiform and moderately wide, 

 with the inferior pudendal membrane visible in basal half. 



Habitat.— ^ew Mexico (Santa Fe, C. V. Riley) ; Arizona (Sulphur 

 Spring Valley, Hubbard and Schwarz) ; Texas (Alpine, elevation 

 4,400-6,000 ieet, H. F. Wickham). 



Number of specimens studied, 3 males, 6 females. 



Type in the LeConte collection. 



Type-locality. — New Mexico ; collected by Mr. Fendler. 



Salient tyj^e-characters. — Thorax subquadrate, slightly narrowed 

 anteriorl}^; sides broadly rounded; apical angles acute, the basal ob- 

 tuse; base broadl}^ rounded. Elytra oval and convex, strongly de- 

 clivous posteriorly, not acuminate at apex; base broadly emarginate; 

 humeri acute; disc quite strongly striato-punctate, intervals with a 

 single series of fine punctules (LeConte). 



Diagnostic characters. — In size and shape dehilis resembles a 

 smooth extricata., from which it diifers in having the anterior femora 

 unarmed in both sexes, and by the distinct and rather distant series 

 of moderate punctures, with a single interstitial series of irregularly 

 spaced fine punctures. 



The punctuation in dehilis somewhat resembles that observed in 

 carl)onaria^ from which it can be separated by its smaller size and 

 female genital characters; the latter also separates it from all other 

 members of the subgenus.
