median vitta on the prothorax; the two flavous vittee on each elytron are sometimes 
indistinct from discoloration. C. bullata, Boh., from Brazil, appears to be a closely 
allied species, but has more gibbous elytra. 
8. Chelymorpha vittata. (Tab. VII. fig. 3, ¢.) 
2. Ovate, rather broad, somewhat gibbous, slightly shining, glabrous; the head, prothorax, and scutellum 
testaceous, the prothorax with a very large subtriangular black patch on either side of the disc; the 
elytra flavo-testaceous, each with two very broad black vitte extending almost from the base to near the 
apex—one near the suture, narrowed and a little abbreviated posteriorly, the other on the outer part of 
the disc, narrowed anteriorly and posteriorly, and extending behind the other to near the suture; the 
antenne and legs rufo-testaceous, the apical four joints of the antenne infuscate; the under surface 
black, the prosternum rufo-testaceous. Head canaliculate between the eyes, the lower part with scattered 
rather coarse punctures ; antenne about reaching the base of the prothorax, the five basal joints shining 
and almost smooth. Prothorax more than twice as broad as long, deeply arcuate-emarginate in front, 
the sides a little rounded behind, obliquely and more rapidly converging from the middle forwards, the 
base bisinuate on either side, the median lobe broad and obtuse, the hind angles a little produced behind ; 
the disc with a fine median groove not extending to the apex, sparsely, very finely punctate ; the margins 
moderately expanded, almost smooth, the outer edge slightly reflexed. Scutellum smooth. Elytra 
somewhat gibbous anteriorly, about four times as long as, and at the base a little wider than, the prothorax, 
widest at one-third from the base, the sides thence to the humeri obliquely converging, the humeri obtuse 
and embraced by the hind angles of the prothorax, the apices conjointly rounded ; the dise very convex 
‘anteriorly, rather abruptly declivous from about the basal third; the margins moderately expanded and 
deflexed ; the entire surface, the sutural region excepted, coarsely, thickly punctate. Beneath glabrous, 
smooth, the metapleure rugose; the prosternum very deeply sulcate for its entire length. Claws 
appendiculate. 
Length 10, breadth 7 millim. 
Hab. Nicaracua, Chontales (Janson). 
One specimen, contained in Mr. O. KE. Janson’s collection. Allied to C. alternans, 
C. rufipennis, &c., but easily separable from these by the very broad black vitte of the 
elytra. C. vittata agrees very nearly with the description of C. militaris, Boh. ; but it 
has much broader and differently formed elytral vitte, the elytra themselves more 
coarsely punctured, and, apparently, the hind angles of the prothorax less acuminate. 
The vitte in C. vittata are nearly twice as broad as the intervening spaces of the ground- 
colour.

Chelymorpha militaris, Boh. Monogr. Cassid. iv. p. 204’. 
‘‘Ovata, convexa, testacea, nitida; antennis extrorsum corporeque subtus nigris ; prothorace sat crebre, sub-

Unknown to me. C. militaris is compared by Boheman with, and placed next to, 
the North-American C. argus (Herbst). ‘The elytral vitte are described as “sat latis,
