‘“s Subrotundata, convexa, rufo-testacea, parum nitida, glabra; prothorace obsolete, subremote punctulato,

I have not seen a Chelymorpha agreeing with the description of this species. The 
spots on each elytron are arranged 2, 3, 1, 2.

11. Chelymorpha rugicollis, (Tab. VII. fig. 4, ¢.) 
Q. Oblong ovate, moderately convex, slightly shining, somewhat thickly pubescent; rufo-testaceous, the eyes, 
six spots on the prothorax—four, equidistant, in a transverse line across the middle (the two on the disc 
larger than the others), and two on the disc at the base, the latter small and faint,—and the scutellum, 
black; the elytra each with seven large rounded spots—three placed one behind the other on the disc. 
towards the suture (the first at the base, the second just behind and almost confluent with it, the third 
about the middle, the latter larger than the others and nearer the suture), three on the outer part of the 
disc (the first on the humeral callus, the second a little before the middle, and the third not far from the 
apex, the latter the largest), and one on the margin a little beyond the middle,—and a common, large, 
-oblong patch on the suture below the base, black; the antenne (joints 8-11 broken off) and legs rufo- 
testaceous ; the under surface black, the ventral segments 3-5 each with a reddish transverse mark at 
the sides. Head rugosely punctured and canaliculate between the eyes, the lower part with coarse, 
separate punctures ; (antenne mutilated). Prothorax nearly twice as broad as long, moderately convex, 
broadly arcuate-emarginate in front, the sides rapidly converging from the base forwards—a little rounded 
behind, obliquely converging in front,—the base deeply bisinuate on either side, the median lobe strongly, 
subtriangularly produced, the hind angles sharply produced behind ; the disc with an abbreviated distinct 
median groove; the apical and lateral margins strongly thickened and reflexed, concave within; the 
entire surface coarsely, confluently punctured. Elytra regularly and moderately convex, about three 
times as long as the prothorax, and at the base a little wider than it, widest at the middle, the sides 
thence to the base sinuously converging, very obtuse behind, the humeri obtuse and embraced by the hind 
angles of the prothorax ; the margins narrowly expanded, with the outer edge thickened and slightly 
reflexed; the surface coarsely, thickly punctate, the spots smoother. Beneath very sparsely, tinely 
punctate, sparsely pubescent ; prosternum very deeply sulcate, Claws appendiculate. 
Length 11, breadth 73 millim. 
Hab. Mexico, Michoacan (Sal/é). 
One example. This very distinct species resembles C. comata, Boh., but is in reality 
more nearly allied to the North-American C. argus (Herbst). The elytra are not at all 
gibbous below the base, this character separating it at once from C. comata and its 
allies. The pubescent, duller surface, coarser punctuation, &c., distinguish it from 
C. argus, C. mexicana, &c. The prothorax is coarsely, confluently punctured.
