Five species of this genus are represented in the Mexican collections before me. 
None of them, however, can be identified with the North-American 8S. electa, Say, 
S. flavonotata, Macq., and S. (Gdicarena) persuasa, Ost. Sack, nor with the Mexican 
S. (Gdicarena) tetanops, Low.

Abdomen broad, flattened, shining rufous, on the sides of the second and each of the following segments 
a black stripe; anal segment shorter than the preceding, black at the tip; ovipositor brownish-rufous, 
very short and truncated. Legs and halteres pale rufous. Wings much longer than the abdomen; the 
base, including the second and third basal cells, yellow ; on the costal region the yellow markings reach 
to a little beyond the end of the first vein, with a branch covering the small cross-vein; the proximal 
part of the discal cell, and a slightly arcuated cross-band, from the end of the submarginal cell to the 
posterior cross-vein, are also yellow; the stigma, a small spot above the origin of the third vein, a stripe 
along the ends of the fifth and sixth veins, a border on the posterior cross-vein, and a border along the 
tip of the wings, are fuscous; the small cross-vein distinctly beyond the middle of the discal cell.
