242 Mr. J. S. Baly’s Descriptions of uncharacterized 
Genus Mesomrpnatta, Hope. 
Mesomphalia Salvinii. 
Subrotundata, modice convexa, viridi-metallica, subnitida, 
subtus nitida; thorace subtilissime punctato, lateribus a basi 
ad apicem rotundato- angustatis, margine antico fulvo; elytris 
dorso antico minus profunde—pone medium margineque sub- 
tilissime—punctatis, utrisque plaga transversa magna, antice 
emarginata, postice sinuata, fulva, zeneo-trinotata. 
Long. 5—6 lin. 
Hab. Panama. 
Extremely close to M. discoides, but at once to be distinguished 
from that insect by its much finer punctation; the elytra are also 
broader, their shoulders being more regularly rounded. Antennz 
equal in length to the thorax, black, four or five basal joints 
fulvous beneath. Thorax opaque, obsoletely punctured; sides 
less dilated than in M. discoides, being regularly narrowed and 
rounded from base to apex. Elytra g much broader than the 
thorax; sides broadly dilated, obliquely rotundate-ampliate at the 
shoulders, thence rotundate-angustate to the apex, the latter con- 
jointly subangulate; the fulvous patch on each elytron is placed 
transversely across the middle of the disc, extending from just 
within the lateral border nearly to the suture; its surface is marked 
with three small zneous spots, placed triangularly on its middle. 
Genus Batonota, Boh. 
Batonota Godmanit. 
Subtriangularis, convexa, obscure fulvo-fusca aut picea, sub- 
nitida; antennis (basi excepta) nigris; elytris viridibus, basi 
retusis, ante medium alte transversim gibbosis, confuse, 
prope suturam  seriatim punctatis, disco laxe elevato- 
reticulatis, ad suturam bicarinatis; humeris antrorsum vix 
productis, acute angulatis, dorso carina obliqua instructis ; 
margine late explanato, fulvo, aneo-punctato, limbo toto 
zeneo. 
Long. 6 lin. 
Hab. Panama. 
Nearly allied to B. bivittipennis, Boh., to which species it bears 
the most striking resemblance in general form, sculpture and 
pattern of coloration; it may, however, be distinguished by the 
colour of the body, and still more easily by the form of the
