OMOPLATA.—BATONOTA. 161 
‘< Subtriangularis, convexa, nitida, supra dilute, sordide testacea, subtus nigra; antennis basi et extrorsum 
verticeque transversim, nigris; prothorace subtiliter, crebre ptinctulato, medio linea abbreviata, macula 
parva transversa utrinque, arcu postico scutelloque nigris; elytris remote, inequaliter punctulatis ; 
humeris antrorsum modice prominulis, leviter rotundatis; tibiis apice extus obtuse calcaratis.—Long. 12, 
lat. 10 millim.”

Unknown to me. Boheman! states that this species is similar in size and form to 
the South-American O. marginata (Linn.) (¢), the type of the genus ; but he gives 
the hind angles of the prothorax as rounded and the apex rotundate, characters quite 
foreign to Omoplata. To judge from the description, O. maculicollis appears to be a 
near ally of Physonota calcarata, Boh.

A genus of similar distribution to Omoplata, but with fewer species, twelve only having 
been described. One of these is from the State of Panama. 
1. Omaspides bistriata. (Tab. VIII. fig. 1.) 
Omaspides bistriata, Boh. Monogr. Cassid. iv. p. 2287. 
Hab. Panama, Chiriqui (Zrétsch), Veragua (coll. Baly +). 
The type is figured. , 
2. Prothorax more or less rounded and projecting beyond the head in front 
(emarginate in some species of Batonota and Hybosa). 
To this group also belong the Eastern genera Basipta, Aspidomorpha, and Laccoptera, 
and the Antillean genus Asteriza.
