CATOBARIS (hoctco, Baris, num. gen.) gen. nov. 



Among the Barini t'roni Florissant is a single species which from its 

 form it is impossiljle to place in any of the known genera and for which, 

 couseqnenth', the al>o\e name is proposed. It is ot a pretty large, size for 

 the group, w itli jiarallel sides, tlie head and prothorax together forming a 

 buUate mass, which is broadest and suhaugulate just behind the front margin 

 of the prothorax, where it is fully as broad as the elytra, though at base it 

 is much narrower. There aie no postocular lobes. The beak is unfortu- 

 nately broken in the only specimen known, Ijut it is rather slender, and the 

 antennge, part only of which are preserved, are evidently short, have rather 

 a stout ovate club, and the terminal joint of the funicle is cuneiform. The 

 femora are nearly as long as the bi-eadth of the body and very nuich ex- 

 panded, while the tibiie, or some of them at any rate, are arcuate.
