Brazil 7; Awntitius 4, Martinique 7. 
Not hitherto recorded from Mexico or Central America. 
17. Mesomphalia evanida. 
Mesomphalia evanida, Boh. Monogr. Cassid. i. p. 881°, and iv. p. 177 2, Cat. Col. Ins. Brit. Mus. 
ix. p. 65°. . 
Hab. Muxico (Truqui, in Mus. Brit.) —Co.omsia !~°. 
There are two specimens of this species in the British Museum labelled as from 
Mexico. MM. evanida is exceedingly closely allied to M. exclamationts, and it is 
probably nothing more than a variety of that insect. 
18. Mesomphalia nigrolineata. (Tab. VI. fig. 17, 3.) 
Rotundate (3), broad ovate (? ), moderately convex, shining, flavo-testaceous or stramineous; the prothorax 
with a narrow median vitta extending from the base to the apex, and the lateral margins from a little 
before the middle to the base, black ; the scutellum black; the elytra with the suture from the base to 
the apex narrowly, a narrow stripe on the outer part of the disc extending from the base nearly to the 
apex (bent inwards and a little widened at the base), and the exterior limb to beyond the middle ( ¢), or 
to about one-third from the base (@ ), very narrowly, black; the antenne black, the four basal joints 
testaceous, 2-4 infuscate above; the under surface and legs pale testaceous, the tibiz on their outer edge 
and the tarsi black. Head deeply canaliculate, not visible from above; antenne rather slender, the four 
basal joints shining, the others densely punctured and opaque. Prothorax twice as broad as long, very 
feebly emarginate in front (the apex subtruncate, if viewed from above), the sides slightly rounded in 
their basal third and thence rapidly and obliquely converging to the apex, the anterior angles obliterated, 
the base feebly sinuate on either side, subtruncate outwardly, the hind angles rather sharp, the median 
lobe obtuse and moderately produced, the disc transversely depressed in the middle behind and with a 
faint median groove, the margins concave, the apex raised; the surface almost smooth, the sides only 
with distinct punctures. Scutellum smooth. Elytra about one-half broader than the prothorax, at the 
base not much wider than it, conjointly rounded at the apex, the base moderately sinuate, the humeri 
rounded and not prominent; the disc regularly convex ; the margins broadly expanded in the g, mode- 
rately expanded in the 9, deflexed, broadly rounded anteriorly; the entire surface thickly, finely 
punctate. Beneath smooth, glabrous. Claws appendiculate. 
Length, 3,9, breadth 8 millim.; @, length 123, breadth 92 millim. 
Hab. Costa Rica (coll. Janson); Panama, Volcan de Chiriqui 4000 feet (Champion). 
One specimen from each locality; the male, from Costa Rica, is figured. This species 
approaches I. albida, M. exclamationis, &c.; but it has the margins of the elytra more 
broadly expanded, especially in the male. 
19. Mesomphalia interrupta. (Tab. VI. fig. 18, 2.) 
Rotundate ( ¢), rather broad ovate ( 2 ), moderately convex, shining, dilute stramineous; the prothorax with 
a median vitta extending from the base to the apex, usually a little widened in front, and the lateral 
margins narrowly from about the middle to the base, black; the scutellum black; the elytra with the 
suture for a short distance immediately below the base, narrowly, a short slightly curved, oblique streak 
on the humeral callus (extending to the base), and a fine longitudinal streak of variable length on the
