Hab. Mexico, Campeche in Yucatan 1-3 (Sallé). 
We have received only a single (¢) specimen of this species, but I have seen 
several others. The humeri are less obtuse in the male than in the female, and they 
are slightly concave in front in the former sex. | 
CHERSINELLA. 
Antenne short, not reaching the base of the prothorax; joints 3 and 4 elongate, slender, 3 nearly twice as 
long as 2 and slightly longer than 4, 5 a little wider and shorter than 4, 6-11 thickened, much stouter 
than 5, 9 and 10 subtransverse, 11 nearly twice as long as 10, acuminate; 1-5 almost smooth and 
shining ; 6-11 densely punctured and opaque. Prothorax nearly twice as broad as long, broadly expanded 
laterally and in front; the apex rounded and extending far beyond the head; the base with a produced, 
rather broad, obtuse median lobe, and thence to the obtuse hind angles subtruncate. Scutellum trian- 
gular, small. Elytra in the male about two and a half times as long as, and very much wider than, the 
prothorax, narrower and longer in the female, convex, very obtuse at the apex, subtruncate on either side 
at the base; the margins broadly expanded and the humeri very oblique in the male, narrower and with 
the humeri obtuse in the female. Claws broadly angularly dilated on the lower side at the base. 
This genus is proposed for the Colombian Cassida heteropunctata, Boh., an insect 
that cannot possibly be retained in the genus Cassida. Chersinella closely approaches’ 
certain species of Physonota (such as P. picticollis, P. maculiventris, &c.) ; but it has 
the antenne differently formed and the claws appendiculate. The humeri are not at 
all produced in front, being oblique in the male and obtuse in the female. The 
antenne are short, and have the six outer joints thickened, the third and fourth 
elongate and slender. 
Boheman states that C. heteropunctata has the facies of a Chelymorpha; it differs 
from that genus, however, in the laterally subtruncate base of the prothorax and elytra, 
and in the short antenne.

Hab. Panama, Tolé (Champion).—Cotomsia 1. 
A single male specimen from Tolé, differing from the type and the two varieties 
described in having a long {-shaped mark on the disc of each elytron, instead of 
some scattered irregular spots; it is like the var. 4, but with the markings longitudinally 
confluent.
