Cassididce. 71 



Long. 6 lin. 



Hah. — Ecuador. 



Antennae scarcely longer than the head and thorax, 

 slightly increasing in thickness towards the apex ; thorax 

 nearly one-third broader than long, sides very oblique, 

 slightly sinuate near the middle. Very close to 0. bistri- 

 gata, Boh. ; the antennae shorter, the elytra less broadly 

 dilated, surface rather more strongly punctured on the 

 disc, the humeral angles less distinct, surface of dilated 

 margin more deflexed. 



Batonota distinda. 



Subtriangularis, apice rotundata, viridi-senea, supra 

 opaca, subtus nigra, nitida ; antennis nigris, basi fulvis ; 

 thorace longitudine plus duplo latiori, lateribus oblique 

 ampliatis, basi rotundatis, fere parallelis, dorso impunc- 

 tato, pube argenteo-sericea adpressa dense vestito ; elytris 

 thorace multo latioribus, humeris antrorsum valde pro- 

 ductis, apice acutis, extrorsum curvatis, dorso carina 

 diagonali divisis ; lateribus ante medium fere parallelis, 

 pone medium ad apicem rotundato-angustatis, apice 

 conjunctim rotundatis; dorso convexis, sparse cinereo- 

 sericeis, basi retusis, deinde transversim gibbosis, sub- 

 fortiter punctatis, punctis prope suturam seriatim, prope 

 marginem, inordinatim dispositis ; interstitiis duobus prope 

 suturam alteroque disci elevatis ; margine laterali tenuiter 

 punctate. Mas, 



Elytrorum humeris antrorsum minus productis, apice 

 subacutis, extrorsum non curvatis ; lateribus pone hu- 

 meros ad apicem rotundato-angustatis, apicem versus 

 citius angustatis, apice conjunctim subacutis. Fcem.

Hah. — Ecuador. 



The male of this species may be at once known from 

 congeneric forms, by the strongly produced humeral 

 angles of the elytra ; and both sexes by the dense seri- 

 ceous pubescence clothing the disc of the thorax. 



Batonota Jansoni. 



Triangularis, convexa, nigra, supra opaca, subtus nitida, 

 antennis nigris ; thorace longitudine fere duplo latiori,
