140 PHYTOPHAGA. 
male of the typical form from Chiriqui, a female of the var. primaria from Cordova, 
and a female of the var. 8 from Cerro Zunil. 
5, Mesomphalia quadrinotata. 
Mesomphalia quadrinotata, Boh. Monogy. Cassid. iv. p. 185°. 
“ Rotundata, modice convexa, cxrulea, nitida; antennarum articulis 2-4 testaceis; prothorace subtiliter, sat 
crebre punctulato, ultra medium oblique ampliato, dein rotundato et basin versus angustato ; elytris sat 
crebre, evidenter punctatis, singulo mox ante medium maculis duabus, transversim positis, luteis, interiore 
ovata, exteriore rotundata, nonnihil majore.—Long. 83, lat. 7 millim.” 
Hab. Costa Rica (Wagner, in Mus. Berol.). 
I have not seen a specimen of this species. Boheman! states that J. guadrinotata 
resembles I. lebasi at first sight ; but is smaller, rounder, and more shining, the elytra 
somewhat coarsely punctured, with the marginal spot larger and nearer to the exterior 
limb, and the humeri subangular. | 
6. Mesomphalia costaricensis. (Tab. VI. fig. 4.) 
Broadly cordate, moderately convex; greenish sneous, ceruleous, or black; the elytra each with a large 
rounded sanguineous or fulvous spot on the expanded margin before the middle, extending to the outer limit 
of the dorsum but not to the lateral margin, and sometimes a minute similarly coloured spot midway 
between this and the suture; the antenne black; the under surface and legs ceruleous or greenish- 
seneous, shining, the former somewhat thickly, the latter sparsely, pubescent; the prothorax and elytra 
(the suture excepted) opaque, almost smooth (minute scattered punctures are visible under a strong lens), 
and clothed with very short, scattered semi-erect whitish hairs. Head deeply canaliculate ; antenne 
rather elongate, extending to far beyond the base of the prothorax, the four basal joints shining, the 
others opaque. Prothorax twice as broad as long, feebly arcuate-emarginate in front, widest a little 
behind the middle, the sides thence to the apex rapidly, obliquely converging, straight or slightly 
converging behind, the base strongly sinuate on either side, and thence to the hind angles nearly straight, 
the latter subrectangular, the median lobe obtuse and moderately produced; the disc with a smooth, faint 
median line, the lateral portions concave, the apical and lateral margins slightly reflexed. Scutellum 
smooth, moderately large. Elytra about three times the length of, and one half wider than, the prothorax, 
broadly cordate, conjointly rounded at the apex, somewhat obliquely converging behind in the male; the 
disc feebly and regularly convex, the suture smooth and shining, and a little raised throughout; the 
margins very broadly expanded, broadly rounded at the shoulders. Beneath sparsely, finely punctured, 
the ventral segments also transversely aciculate. 
Length 114-123, breadth 103-113 millim. 
Hab. Costa Rica (Van Patten), Volcan de Irazu 6000 to 7000 feet, Rio Sucio (Rogers), 
Fifteen specimens. This insect has somewhat the facies of an Omaspides. It may 
easily be known from the similarly coloured two-spotted variety of M. lebasi by the 
almost smooth, very dull upper surface, and by the more concave margins of the pro- 
thorax. ‘The males are a little shorter than the females, the shoulders being broadly 
rounded in both sexes. 
.7 Mesomphalia xanthospila. (Tab. VI. fig. 5, ¢.) 
3. Subcordate, broad, moderately convex; greenish-eneous, the anterior margins of the prothorax (except in 
the middle) fulvous; the elytra each with a broad F-shaped mark on the middle of the disc at the base,
