342 Mr. J. S. Baly on new Genera and Species of Hispidse. 



nearly twice as broad as long at the base, flattened on the 

 hinder disk, subcylindrical in front ; surface deeply and closely 

 impressed with large punctures, rugose. Scutellum semiovate. 

 Elytra broader at the base than the thorax, gradually but slightly 

 increasing from their base to the hinder angles; shoulders 

 oblique ; lateral and apical margins narrowly dilated, coarsely 

 serrate ; interspaces between the co8ta3 deeply and coarsely bi- 

 gemellate-punctate ; on the outer disk, just above the com- 

 mencement of the third vitta, the puncturing is somewhat 

 confused.

Uroplata concava, n. sp. 



U. elongata, subparallela, subdepressa, obscure rufo-fusca, subnitida; 

 thoracis vittis duabus nigro-fuscis ; pedibus flavo-fulvis : elytris 

 fere parallelis, apice conjunctim concavis, serratis, angulo postico 

 in laminam acutam, trigonam, postice serratam, extrorsum vix 

 dilatatam, retrorsum pauUo productis ; utroque tricostato, inter- 

 spatiis profunda bifariam punctatis, interspatio tertio poue medium 

 confuse punctato. 



Long. 3| lin. 



Hab. Amazons. 



Head strongly produced between the eyes, vertex subopake, 

 slightly concave behind, furnished with a longitudinal ridge in 

 front; antennae very robust, incrassate, two basal joints short, 

 almost transverse, thickened, nearly equal, four following joints 

 short, cylindrical, transverse, nearly equal, the sixth being 

 scarcely perceptibly shorter than the fifth ; seventh nearly as 

 long as the two preceding united, coalescent with the four ter- 

 minal joints, which together form an opake compressed club, 

 dilated at its upper edge, their sutural lines visible under a lens. 

 Thorax about one- half broader than long at the base, sides 

 moderately narrowed and rounded from base to apex, anterior 

 angles armed with an obtuse tooth ; above subcylindrical, flat- 

 tened and transversely depressed on the hinder disk, surface 

 closely covered with coarse deeply impressed punctures, sides 

 rugose ; basal lobe oblique, broadly truncate, not transversely 

 grooved. Scutellum transverse, sides diverging from the 

 base towards the apex, the latter obtusely truncate. Elytra 

 broader than the thorax, subparallel, scarcely increasing in 

 width near the hinder angles ; sides very narrowly margined, 

 their outer edge finely serrate, suture (more particularly in front) 

 strongly costate. Thighs armed with a short tooth beneath.
