the sides and at ‘the Base, remote on the medial disc. Elytra oblong, acutely rounded 
at the apex, convex; distinctly punctured, flavous; each with the apical fourth and 
three large patches, placed two obliquely below the. base, one on the humeral callus, 
the other on the inner disc, and a third transverse, obliquely placed near the middle, 
black. Extreme apex of abdomen fulvous. 
This insect differs from A. ornatus in the less coarsely punctured and entirely black 
thorax; in all other respects the two species closely agree. Its coloration is constant, 
so that I have considered it as distinct from the preceding insect. . 
Mr. Champion found this species upon the leaves of Musacez in the virgin forest of 
the low country.

Alurnus cassideus, Westw. Ann. Nat. Hist. i. 1841, viii. p. 204°. 
Hab. Mexico (coll. Melly).—Urrser Amazons!, Pebas (Bates); Ecuapor (Buckley). 
The variety with black elytra from Ecuador, described by Mr. C. O. Waterhouse 
[Proc. Zool. Soc. 1881, p. 265], is much narrower than the typical form, and probably 
belongs to another species. 
XANTHISPA. 
Xanthispa, Baly, Cat. Hispide, p. 31. 
Although the insect here described differs from the original diagnosis of Xanthispa 
(2. c. p. 32) in having the second joint of the antenne short, it agrees so completely in 
the formation of the parts of the mouth with the typical species |X. cimicoides, Guérin, 
from Cayenne], that I do not hesitate to place it in the same genus. 
1. Xanthispa ceruleipennis. (Tab. I. fig. 8.) 
Ovata, subdepressa, rufo-testacea, nitida; antennis, articulo basali excepto, oculis scutelloque nigris; antennarum 
articulis basalibus duobus brevibus equalibus, tertio elongato; thorace transverso, levi, lateribus reflexis, 
a basi ad apicem convergentibus; elytris late ovatis, metallico-ceruleis, sat fortiter punctato-striatis, 
interspatiis ad latera convexis, hic illic costatis. . 
Long. 24 lin. 
Hab. Nicaraeua, Chontales (Belt). A single specimen. 
Antenne half the length of the body; two lower joints very short, equal, the basal 
one not thickened ; third joint longer than the preceding two united. Thorax trans- 
verse ; sides regularly rounded, and converging from base to apex ; the anterior angles 
obtuse ; apical margin concave; disc impunctate ; the lateral margin reflexed. Scutellum 
pentangular. lytra broadly ovate, rounded on the sides, more broadly rounded at the 
apex, outer margin minutely serrulate; disc slightly convex, flattened along the suture, 
broadly excavated laterally before the middle; rather strongly punctate-striate ; striee on
