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
