quadricostatis, costis duabus exterioribus apice confluentibus, 
tertia medio fere interrupta ; obscure nigro-purpureis, maculis 
parvis numerosis disci, maculaque transversé communi ante 
apicem, fulvis ; femoribus anticis subtus spina brevi armatis. 
Long. 2 lin. 
Hab. Brazil. 
Head moderately produced between the eyes, vertex lon- 
gitudinally grooved ; antennz longer than the head and thorax, 
robust, subincrassate, two basal joints short, equal, the basal one 
slightly thickened, third rather longer than the second, fourth 
scarcely equal to the third, fifth and sixth very short, transverse, 
nearly equal, the sixth however being visibly shorter than the 
fifth, seventh nearly as long as the two preceding. taken conjointly, 
thickened, and forming with the four terminal joints an elongated 
slightly-compressed club ; the sutural lines between the last four 
joints obsolete. Thorax twice as broad as long, sides obliquely 
narrowed from just above the extreme base to the apex ; upper 
surface subcylindrical in front, flattened and transversely excavated 
on the hinder disc, deeply impressed with large deep round pune- 
tures, which, closely crowded on the sides, are irregularly placed 
at much more distant intervals on the disc ; whole surface of basal 
lobe excavated, depressed. Scutellum transverse, its apex obtuse. 
Elytra scarcely broader at their base than the thorax ; humeral 
callus laterally prominent, its apex not extending beyond the lateral 
border, obtuse; sides gradually dilated from below their base to 
the hinder angles, narrowly margined, their outer edge distantly and 
irregularly serrate; hinder angles produced slightly outwards and 
obliquely upwards and scarcely backwards inte a triangular plate, 
the upper surface of which is deeply concave, its apex obtuse, and 
its apical border armed with four or five coarse teeth; upper sur- 
face flattened, interspaces deeply gemellate-punctate, the first irre- 
gularly punctured at the base, a space on the outer disc just below 
the middle, extending between the second and fourth costz, irre- 
gularly punctured. 
5. Uroplata terminalis. 
Elongata, apicem versus vix ampliata, subdepressa, obscure 
fulva, subnitida; pedibus flavis; vertice macula utrinque, 
antennis, thorace utrinque vitta lata laterali, abdominisque 
segmento ultimo, nigris; elytris apice obtusis, distincte 
subfortiter serratis, angulo postico parum prominulo, ro- 
tundato, utrisque tricostatis, linea suturali postice abbre-
