of tlie said carina, differing, however, from it in general appear- 

 ance. The colour is that of S. atutas, but a shade or two darker, 

 the insect being at the same time larger and altogether more 

 robust. The eyes are small. Antcnnal club three-jointed, the 

 joints forming it gradually increasing in size, ohovate, flat at 

 the base, the last acuminated. Scutellum obsolete. Elytra with 

 two slight basal impressions, the tiaces of a humeral costa, sepa- 

 rately rounded-off at the apex. Legs elongated as usual ; two 

 posterior coxse distant ; tibiae straight, subeyliudric, but not nar- 

 rowed at the apex, the four anterior ones hairy ; tarsi with joints 

 1-4 almost imperceptibly decreasing in size, or perhaps 2-3 

 equal, the anterior ones slightly contracted, these and the inter- 

 mediate ones hairy on the inside. Mesosternal carina middling, 

 flat on the Ijack, with a shallow, but very distinct, longitudinal 

 groove or excavation, anterior part projecting, acuminated.

An anomalous species with regard to its general appearance, 

 which differs considerably from that of the rest of the grouj), 

 and makes it, as I have remarked above, the connecting link 

 between this and the following grouj). This is the largest spe- 

 cies I have hitherto met with. The system of coloration is the 

 usual one, — more or less deep brown, legs and antennre lighter, 

 tarsi and palpi very light. Eyes middling. Antenna with a 

 3-joiuted club, the joints subglobose, flat at 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 sub- 

 perfoliated appearance. The mandibles are furnished with a 

 bifid tooth. The third joint of the maxillary palpi has the shape 

 of an inverted cone, the fourth minute and truncated at the 

 apex. The thorax is of an obuvate form, about | longer than 

 broad, r;uindcd-off before and gradually narrowed belou'^ the 

 middle, isubquadrate at the base, impressed with four foveje or 

 pits, the posterior angles roundtd-ofl". Scutellum minute. Ely-
