together, ol)tiisely pohited. Palpi yellow. Head broad; 

 the eyes very large, even broader than the elytra; the 

 elyj)eiis armed in front Avith two very elongate, pitehy- 

 yellow spines, whieh arc ciliated internally, the horny 

 elyj)eus deeply impressed and separated by a straight 

 depressed line from the front; the front with elevations 

 and depressions so placed as to form a central elevated 

 space, surrounded, except at the summit in tlie middle, by 

 a broad, iri'cgular de])ression; also with a fine depression 

 along the inner margin of the eyes, in Avhich are a few 

 ])unctui-es. Thorax broad, Avith four transverse furrows 

 in which are large punctures; the first of these grooves is 

 ])laced near the front margin, Avhose course it follows; the 

 second extends in a nearly straight line across the thorax, 

 so that it is nearer to the front one at the sides than in the 

 middle, — it can scarcely be said to be interi'uptcd in tlie 

 middle ; the third furrow is the broadest and is distinctly 

 interrupted in the middle, the hinder one is placed close 

 to the base; the sides appear a little waved and have two 

 angular projections near the front. Scutellum emarginatc- 

 truncate at the apex, bearing two foveie. Elytra broad, 

 broader than long, about as long as the thorax, dee])ly 

 impressed at the base for the thorax ; each near the 

 shoulder Avith an oblique stria, sharply limited on the 

 inner but not on the outer side. Legs yellow; coxte 

 castaneous. 



Ega; two specimens, both of Avlilch appear to be 

 females. 



Obs. — Besides the tAvo females aljove described, I have 

 also tAvo males of this species, Avliich I obtained from the 

 collection of Mr. E. W. Janson, Avhere they Avere labelled, 

 " Parii, Brazil." These tAvo males have the ventral ])late 

 of the 7th segment of the hind body slightly emarginate 

 on each side the middle at the extremity: and the ])re- 

 ceding segments are slightly flattened along the middle, 

 and furnished there Avith a A'cry fine and scanty short 

 ])ubescence. The structure of the antcnnre is cpiite the 

 same as in the females.
