Stal (Hem. Afr. ii. p. 114) describes this species, of which it is 
stated ‘“ Exemplum typicum Westwoodi haud examinavi,” as having 
the “ rostrum coxas posticas attingens.” The rostrum, however, is 
much longer and generally reaches the third abdominal segment. 
This is the real distinguishing character which separates the species 
from S. hematica Germ.
