342 Mr.J.8. Baly on new Genera and Species of Hispide. 
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 coste 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 paullo productis ; utroque tricostato, inter- 
spatiis profunde bifariam punctatis, interspatio tertio pone medium 
confuse punctato. 
Long. 33 lin. 
Hab. Amazons. 
Head strongly produced between the eyes, vertex subopake, 
slightly concave behind, furnished with a longitudinal ndge in 
front ; antennz 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 joimts, 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 increasimg 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.
