club three-jointed, the joints forming it gradually increasing in 

 size, obovate, flat at the base, the last acuminated, Scutellum 

 obsolete. Elytra with two slight basal impressions, the trace 

 of a humeral costa, separately rounded off at the apex. Legs 

 elongated as usual ; two posterior coxae distant, tibiae straight, 

 subcylindric, but not narrowed at the apex, the four anterior 

 ones hairy ; tarsi with joints 1-4 almost inperceptibly decreas- 

 ing in size— or perhaps 2-3 equal, — the anterior ones slightly 

 contracted : these and the intermediate ones hairy on the in- 

 side. Mesosternal carina middling, flat on the back 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 group, 

 and makes it, as I have 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 antennas 

 lighter, tarsi and palpi quite so. Eyes middling. Antennae 

 with a three-jointed club, the joints 6-8 are slightly truncated at 

 the apex, 7 and 8 being at the same time strongly compressed 

 have a subperfoliated appearance. The mandibles are fur- 

 nished 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 quarter longer than broad, rounded off before and gradually 

 narrowed below the middle, subquadratic at the base, impres-
