Described from three females and one male from Omilteme 

 and Xucumanatlan in Guerrero (H. H. Smith) and Ciudad 

 Mex. (Forrer). One female from Vienna Museum, labeled 

 "Mexico Coll. Sign, {hebrceus det. Sign.) (114)," which is slightly 

 darker than the rest but does not differ otherwise. 



Phlepsius {lowanus) spatulatus V. D. (Fig. 4b and c). 



This is a smaller, paler, and less definitely marked species, 

 occurring commonly from Colorado south to Central Mexico. 

 Specimens are at hand from Mexicali, June; Ti-Juana, August 

 (Ball); El Taste and Presidio Mex. (Forrer). The short teeth 

 on the female segment separated by an acute notch will readily 

 separate this species from any other. 



Subgenus Texananus nov. 



Resembling Phlepsius but with head narrower than the 

 pronotum, front rather broad, convex, widening above the 

 antennae and approaching the eyes. Vertex bluntly conical, the 

 margin to the front rounding. Pronotum large, broadly and 

 evenly rounding in front; the lateral margin long, oblique, and 

 definitely carinate. Elytra broader and shorter than in lowanus, 

 whole surface inscribed with vermiculate lines. Type of the 

 subgenus Phlepsius {Texananus) mexicanus n. sp.

Phlepsius {Texananus) eugeneus //. sp. (Fig. 5b and c). 



Nearly of the form of excultus but larger, paler, and lacking the 

 definite markings of that species. Pale grayish or slightly fulvous 

 brown. Length 7 mm., width 3 mm. Vertex convex, one-fourth longer 

 on middle than against eye, twice wider than long. Anterior margin 

 bluntly rounding except at apex, front broader than in hebrceus, almost
