inner corner, the outer edges of the styles curved, the inner edges 

 sinuous, spine at base pointing upward, not outward. 



(3) S. granulosa (Fowler) 



The specimens I have from Orizaba under this name differ 

 slightly from Fowler's description; from hoeheli they differ 

 in having the process on anal segment very much shorter and 

 the styles are widest shortly before apex. 



(4) S. l-oeheli sp. nov. (59) 



A very short furcation at base of median facial keel. Scutellum, 

 pronotum, vertex, antennae and face between eyes brown, face below 

 eyes and genae yellow, speckled with brown at apex; clypeus brown; 

 keels on head and thorax lighter in color; female abdomen yellowish 

 with brown spots, male abdomen brown with small yellowish marks 

 near base; femora brown, especially in male, all tarsi and tibiae 

 banded with brown. Tegmina hyaline, veins not colored, dotted with 

 large, brown, hair-bearing granules, a curved brown mark over first 

 median sector and cubitus, a light brown spot in median cell and the 

 clavus slightly fuscous. 



Medio-ventral edge of pygophor deeply and roundly emarginate, 

 the corners of the emargination forming subacute points; anus at 

 base of anal segment, the ventral portion of segment beyond anus 

 flattened, gradually narrowed to the acutely pointed apex, and curved 

 under; genital styles curved, meeting together at their bases and 

 forming a "horse-shoe," narrow, subequal in width to truncate apices, 

 which are slightly widened, from their bases where they touch arise 

 two small, stout spines. 



Length 2.5 mm. ; tegmen 3.4 mm. 



Hab. Morelos, Mexico. (A. Koebele coll.) 



I take pleasure in naming this species after Mr. A. Koebele. 



(5) S. azteca sp. nov. ( $ 9 ). 



Facies very similar to kocbeli, but inclined to have the lighter 

 marks more extensive. The male pygophor medio-ventrally emargin- 

 ate, the sides cut back; the anal segment short, the ventral edge 

 beyond anus forming a downward-pointing, short spine reaching 

 about two-thirds to ventral margin; styles slightly curved, thin and 

 cylindrical at base, slightly flattened on apical half, truncate at apex 

 with each corner drawn into a small spine, an outwardly pointing 

 spine at the base of each style, joined together at their bases. This 

 differs from (iramnom by having a spine on the anal segment and not
