margins. The second fascia is immediately behind the middle 
of the length, and touches the lateral margins ; it is straight and 
nearly twice as wide as the front fascia, its lateral apices con- 
siderably dilated. The hindmost fascia is somewhat of a 
half-moon shape,—viewed with the head of the insect next the 
observer, it resembles an open umbrella,—and is near the apex. 
The prothorax, at its widest, is scarcely more than three-quarters 
the length of the widest part of the elytra; it is half again as 
wide as long, and nearly twice as wide across the base as across 
the front. Its puncturation is about as close as that on the pro- 
thorax of S. amphicroa, Boisd., but is a trifle finer (except in 
front of the scutellum where it is stronger and less close), 
and less rugulose. Its form is strongly convex in all directions, 
so that it appears decidedly gibbous. The head is moderately 
elongate and moderately concave longitudinally ; its puncturation 
is much like that of the prothorax. The underside is closely and 
finely punctured. 
This species seems to be near Burchelli, L. & G., but differs 
from it and its described allies by the the trispinose apex of 
each of its elytra; of the three apical spines the middle one is 
the largest and the least acute ; the others are small and sharp.

Extremely like S. Andersoni, L. & G. It is a shorter and 
more depressed insect, with the elytra much more dilated behind 
the middle. The prothorax is much more strongly and sparsely 
punctulate, and is without any trace of a fovea in the hind 
angles ; the scutellum is much less transverse; the punctures in
