An anomalous species with regard to its general appearance 
which differs considerably from that of the rest of the group, and 
makes it, as I remarked above, the connecting link between 
this and the following group. This is the largest species I have 
hitherto met with. The system of coloration is the usual one : 
more or less deep brown, legs and antennae lighter, tarsi and palpi 
quite so. Eyes middling. Antennae with a 3-jointed club, the 
joints sabglobose, flat on the base, the last large, conic, joints 6-8 
are slightly truncated at the apex, 7 and 8 being at the same time 
strongly compressed have a subperfoliated appearance. The man- 
dibles are furnished with a bifid tooth. The 3rd joint of the maxill. 
palpi is of the shape of an inverted cone, the 4th minute and trun- 
cated at the apex. The thorax is of an obovate form, about one- 
fourth longer than broad, rounded off before and gradually nar- 
rowed below the middle, subquadrate at the base impressed with 
4 foveae or pits, the posterior angles rounded off. Scutellum minute. 
Elytra with 2 short humeral costae, separately rounded off at the 
apex. Legs stout ; 2 posterior coxae distant ; tibiae slightly bent 
at the base, subcylindric at the apex, the 4 anterior ones hairy ; 
tarsi with joints 1-4 gradually decreasing in size, the anterior 
ones dilated, the joints transversely triangular, the intermediate 
pair hairy on the inside. Mesosternum of the preceding. Me- 
tasternum with a slight longitudinal depression down the mid- 
dle. Penultimate abdominal segment grooved on the back as in 
S. alatus. The enlargement of the anterior tarsi (as in other beetles) 
indicates undoubtedly a sexual distinction, since it is not equally
