STOMYLES. 



Stomyles, Seudder, Rep. Peabody Ac. Sci. iv. p. 76 (1872). 



This genus, the type of which is Pyrgus textor, Hubn., is sunk by Watson as a 

 synonym of Amblyscirtes ; but as the male has a differently shaped brand *, and the 

 second median segment of the primaries is also a little lengthened to make room for 

 the upper portion of it, we retain the two as distinct. The lower radial nervure is 

 slightly depressed at the base, as in certain species of Amblyscirtes; the terminal joint 

 of the palpi also varies in length according to the species, being rather short in 

 8. textor and others, and moderately long and erect in 8. nereus. The brand of the 

 male is formed of two longitudinal streaks, one running beneath the entire length of 

 the second median segment and a second under the first median branch, this latter in 

 8. textor extending nearly to the base of the wing ; in S. florus there is an additional 

 piece just above the submedian nervure. In all other respects Stomyles agrees 

 with Amblyscirtes, and the genitalia of the males are also very similar. In addition 

 to Pyrgus textor, Hiibner, the genus includes Amblyscirtes tolteca, Scudd., Hesperia 

 nereus, Edw., and possibly H. comus, Edw., as well as a new species from Mexico 

 described below.

1. Stomyles tolteca. (Tab. xcv. figg. 21, 22, 23, j .) 



Amblyscirtes tolteca, Scudd. Rep. Peabody Ac. Sci. iv. p. 76 (1872) \ 



Alis nitide fuscis, stigmate concolore, anticis puneto duplici in cellula, tribus in linea transversa subapicalibus, 

 quinque in serie sinuosa obliqua a margine interno prope apicem extendente, albis ; posticis punctis 

 minutis variis discalibus fere obsoletis : subtus ut supra, sed anticis punctis magis obviis, punctis sex aut 

 septem in serie submarginali flexuosa, aliis quatuor basin propioribus, albis. 



2 mari similis. 



Hab. Mexico, Presidio de Mazatlan (Forrer), Acapulco (.7. J. Walker), Jalapa (coll. 

 Schaus), Valladolid in Yucatan (Gaumer), Tehuantepec 1 . 



We have two females from Yucatan and two males from Western Mexico which we 

 assign to this species ; there is also a male of it in Mr. Schaus's collection. The male 

 from Acapulco differs slightly from the rest in having the white spots of the primaries 

 larger. Scudder's types, from Tehuantepec, male and female, have been examined. 



8. tolteca resembles Amblyscirtes nanno (Edwards), but differs from it in having a 

 double white spot in the cell of the primaries; the outer oblique series of spots is more 

 sinuous; and the male has a differently shaped brand. For the genitalia of the male, 

 see Tab. XCV. fig. 23. 



* The North-American A. samoset, Scudd., differs again from Amblyscirtes in the shape of the brand, the 

 upper piece being elongate-triangular, and the lower piece in the form of a longitudinal streak. This insect, 

 however, has the first branch arising from very near the base of the median nervure.
