This well-known genus includes nearly one hundred described species, few of 
which are from the New World. The North-American forms, however, are numerous 
and require revision. Of the ten here enumerated from within our limits, S. signoreti, 
Guér. (=ornata, Stal), is the only one inhabiting the sea-coast, where fresh species 
are certain to be discovered, the others being from the banks of ponds or streams. 
Following Dr. Reuter’s system of arrangement, S. signoreti should form the type of 
a new subgenus near Chiloxanthus, the other Central-American forms belonging to his 
section Acanthia. 
a. Species large and elongate (length 64-7 millim.), with a very long 
second joint to the antenne, which are entirely pale ; upper surface 
dull and simply pubescent ; pronotum and elytra more or less 
variegated with whitish ; membrane with five areole . . signoreti, Guér. (ornata, Stal). 
5. Species small (length 23- 5 millim.), ovate or oblong-ovate in shape ; 
membrane with four areole. 
a’, Upper surface with long, erect hairs, and a more or less distinct 
short decumbent pubescence. 
a’, Head, pronotum, and scutellum very shining; the lateral margins 
of the pronotum black. 
a’, Elytra shining throughout . . . . . . . . . . . Jbevis, n. sp. 
6’, Corium shining, the clavus (except along the suture) opaque ; 
the sides of the pronotum straight and rapidly converging 
from the base forwards ... . - . « . sulcicollis, n. sp. 
ce’, Elytra opaque ; the pronotum much dilated at the sides : form 
short ovate . . . . . . . . + Opacipennis, 0. sp. 
b’. Head, except in front, pronotum, and seutellum slightly shining, 
the elytra opaque; the lateral margins of the pronotum flavous. comata, n. sp. 
b’. Upper surface with a short decumbent pubescence only. 
c’’, Lateral margins of the pronotum black. 
d’’, Pronotum slightly rounded at the sides, comparatively broad 
in front. 
a‘, Elytra with small flavous spots, the pronotum somewhat 
broadly dilated at the sides . . . . . . . . . . saltatoria, Linn. 
b*. Elytra with the flavous coloration more extended, the pro- 
notum more narrowed in front . . . . . . « . « tropicalis, n. sp.
