CISTUDINELLA.—PHYSONOTA. 165 
mesosternum, deeply grooved on either side posteriorly (but not down the middle); claws divaricate, 
simple; form elliptic or oval. 
This genus is proposed for the South-American Chelymorpha punctipennis, C. apiata, 
and C. obducta, Boh., and for the new species from Chiriqui described below*. In 
Chelymorpha the head is not so deeply inserted, it being usually prominent, the pro- 
sternal process is deeply sulcate down the middle, and the claws are appendiculate, 
2. é. angularly dilated on the lower side towards the base. 
1. Cistudinella foveolata. (Tab. VIII. fig. 8, 3.)

Soa ai 3. Subelliptic, convex, rather broad, shining, testaceous, the expanded margins of the prothorax and elytra 
jure 
somewhat pellucid; the eyes and antenne black, the five basal joints of the latter testaceous; the body 
beneath black, the ventral segments broadly bordered with testaceous; the legs entirely testaceous. 
Antenne about reaching the base of the prothorax; joints 6-11 rather stout and compressed, 6-10 as 
broad as long, 11 acuminate, longer than 10. Prothorax twice as broad as long, very rapidly, arcuately 
converging from the base, rounded in front and projecting over the head, the base broadly arcuate- 
emarginate on either side, the median lobe produced, rounded at the tip, the hind angles sharp; the disc 
transversely depressed in the middle before the base; the margins broadly expanded, deeply transversely 
depressed in front and behind, reticulate; the surface smooth, the disc only with a few fine, scattered 
punctures at the base. Elytra about two and a half times as long as, and at the sides forming almost a 
continuous outline with, the prothorax, conjointly rounded at the apex; the dise transversely convex 
before the middle and then somewhat obliquely declivous to the apex, with coarse, deep, widely scattered, 
subserially arranged black punctures, the interspaces smooth and flat; the margins rather broadly 
expanded, smooth, reticulate; the humeri obtuse and embraced by the hind angles of the prothorax. 
Beneath shining, almost smooth. 
Length 7, breadth 53 millim. 
Hab. Panama, David in Chiriqui (Champion). 
One specimen. Closely allied to the Brazilian C. apiata, Boh., but differing from 
it in having the prothorax less dilated at the sides anteriorly (more rapidly converging 
from the base), and the elytral punctures much less numerous, the interspaces quite 
flat ; the general shape is also more elliptic. 
PHYSONOTA. 
Physonota, Chevrolat, Dej. Cat. 8rd edit. p. 898 (1837); Boheman, Monogr. Cassid. ii. p. 190 
(1854) (partim) ; Chapuis, Gen. Col. xi. p. 386. 
The name Physonota is here adopted solely for those species that have the claws 
simple, Boheman having also included under it, as noted by Chapuis, some South- 
American forms (P. fuscula, &c.) with the claws appendiculate. The metropolis of 
Physonota would appear to be in Mexico, though only one or two representatives occur 
north of our boundary; the species are all American, ranging from Canada to 
Chili. Many of the species of Physonota, and of the genera that follow, are, as is well 
known, brilliantly metallic golden in life. |
