Mr. J. 8. Baly on new Species of Cassididee. 9 
very convex, obsoletely gibbose before the middle, deeply rugose-punc- 
tate, covered with a strongly raised irregular reticulation enclosing 
small interspaces ; on each side, a short distance within the suture, is a 
strongly raised longitudinal ridge, which sends short transverse branches 
to the suture ; lateral margin broadly dilated, its surface sinuate ; below 
its middle is an irregularly excavated transverse black patch, which 
extends a short distance on to the limb of the disk. 
The species is much more strongly rugose than any other with 
which I am acquainted. 
Prioptera gibbosa. 
P. ovato-rotundata, valde convexa, fulva, subnitida, subtus nitida ; thorace 
utrinque basi nigro maculato; elytris sat fortiter punctatis, infra basin 
excavatis, ante medium in gibbum compressum acutum elevatis, disco 
hie illic irregulariter excavatis, pone gibbum late foveolatis, confuse 
elevato-reticulatis ; utroque maculis quatuor magnis, duabus infra 
basin duabusque pone medium, seriebus duabus transversim positis, 
secunda in serie posteriore ad marginem lateralem adfixa, nigris; mar- 
gine exteriore late explanato.—Long. 5 lin.

Ovate-rotundate, fulvous, subnitidous, shining beneath. Antenne 
scarcely longer than the thorax, entirely fulvous. Thorax smooth, 
impunctate, its basal lobe impressed with a round deep fovea, from 
the apex of which an indistinct groove runs upwards on the disk; on 
either side of the latter, attached to the base, is a large nigro-piceous 
patch. Elytra very convex; sides obliquely ampliate and slightly 
rounded from their base to the middle, then for a short space rotundate- 
angustate, thence to the apex obliquely angustate, the apex itself being 
subangulate ; upper surface elevated before the middle into a trans- 
versely compressed, subacute gibbosity, the surface of which is covered 
on either side with three large foveze, two in front, oblong, the third 
on the hinder surface, irregular; disk distinctly punctured, the punc- 
tures being indistinctly arranged on the outer side in irregular striae ; 
surface irregularly pitted, confusedly elevate-reticulate; each elytron 
with four large black spots, arranged as follows :—one below the base, 
on the outer surface of the gibbose portion; the second just below the 
humeral callus, parallel with the first ; the third nearly halfway between 
the middle and apex, close to the suture; and the fourth parallel to the 
third, placed on the outer margin, its surface excavated ; dilated border 
smooth, concave before the middle. 
Prioptera nigricornis. 
P. oblonga, convexa, nitida, pallide flavo-fulva, plaga metasterno anten- 
nisque (harum articulo basali excepto) nigris; thorace levi, basi tenuiter 
nigro marginato, disco nigro binotato; elytris basi non gibbosis, disco
