1918] Phlepsids of Mexico and Central America 385 



Color. Pale yellow, two pairs of approximate dots on suture between 

 vertex and pronotum as in excultus, two indistinct brown spots at apex 

 of vertex, and front brown with pale dots. Elytra milky, inscribed 

 with brown, faintly washed with rufous in most specimens, the tips of 

 the claval nervnires fuscous. 



Genitalia. Female segment long, angularh- narrowing posteriorly, 

 middle half roundingly emarginate clear to the base where there is a 

 slight median tooth. Male valve very short and obtuse; plates large, 

 triangular, with nearly straight margins, white with black spots at the 

 base of the short marginal hairs; the stout spines of the pygofers 

 exceeding those of the plates. 



Described from twelve specimens from Acuguizotla, Guer- 

 rero, 3,500 ft. Oct. (H. H. Smith); Amula, Guerrero, 6,000 ft. 

 Sept. (H. H. Smith) ; Das Arroyos, -Guerrero, 1,000 ft. Sept. 

 (H. H. Smith); Tierra, Colorado, Guerrero, 2,000 ft. Oct. 

 (H. H. Smith); Cuernavaca, May; and Iguala, Mex. 



This species may be separated from excultus by the absence 

 of definite fulvous and wavy markings along the dorsum, as 

 well as by the much longer notch in the female segment, and 

 from spatulatus which it resembles by the distinct genitalia. 



Phlepsius {Te.xaiianus) superbus T'. D. (Fig. Gb and c). 



This compact, dark brown species much resembles mexicanus 

 but is slightly smaller and more elongate. The very dark face 

 and distinct genitalia will readily distinguish it. 



It occurs from Colorado and Oregon south to Central 

 Mexico. Specimens are at hand from Ti .Juanai, June (Ball) 

 and Mescala, Guerrero Mex. (H. H. Smith). 



Phlepsius (Texananus) mexicanus n. sp. (Fig. 7a, b, c, d and e). 



Closely resembling P. areolatus but quite distinct in shape of vertex 

 and genitalia. A stout species with the brownish fuscous irrorations 

 irregularly distributed, leaving patches of milk white. Length ().75 mm., 

 width 3 mm. 



Vertex convex, with the front almost conical, nearly half longer on 

 middle than against eye, almost three times wider than long, front 

 broad wedge-shaped but little longer than its basal width. Elytra broad 

 and short, the apices appressed; apical cells short. 



Color. Vertex testaceous brown, three irregular blotches on the 

 anterior margin and numerous dots on the disc pale; pronotum tes- 

 taceous brown, with irregular hieroglyphic light markings on anterior 

 half and light pustulate spots on the remainder. Scutellum with the 

 apex and two marginal spots light. Elytra milk}' white, the nervures 

 fuscous brown, the vermiculation mostly coalesced into fuscous dots- 

 which are larger toward the margins.
