MESOMPHALIA. _ | 141 
and a very large subtriangular patch on the disc a little beyond the middle, the latter connected externally 
with an equally large slightly curved antemedian lateral patch, these markings not reaching the sutural 
or lateral margins, yellow; antenne and legs black, the joints 1-3 of the antenne narrowly fulvous at 
the tip: beneath black, shining. Head rugosely punctured, opaque, deeply canaliculate; antennse with 
the four basal joints shining, the others opaque. Prothorax subopaque, twice as broad as long, deeply 
arcuate-emarginate in front, the sides rapidly arcuately converging from the base, somewhat obliquely so 
. towards the anterior angles, the base subtruncate on either side, the median lobe obtuse and moderately 
produced, the disc with a fine, smooth median line, the surface sparsely, very minutely punctured. 
Scutellum smooth. Elytra more than three times the length of, and one half wider than, the prothorax, 
broadly subcordate, conjointly rounded at the apex; the disc moderately shining, regularly convex, thickly, 
finely punctured, the suture a little raised posteriorly, smooth; the margins very broadly expanded 
anteriorly, more narrowly so posteriorly, somewhat obliquely rounded at the shoulders, the median patch 
shining, more closely punctured than the disc, the other part opaque, minutely punctured, the exterior 
limb slightly thickened and reflexed. Beneath subglabrous, almost smooth, shining. 
Length 12, breadth 10 millim. 
Hab. Guatemaa, San Juan in Vera Paz (Champion). 
One example. Exceedingly close to UV. salvini, but with very different elytral 
markings, the disc of the elytra a little more uniformly punctured. 
8. Mesomphalia quadriguttata. (Tab. VI. fig. 6,9.) 
Q. Broad ovate, moderately convex; greenish-sneous, the anterior margins of the prothorax (except in the 
middle) fulvous; the elytra each with a large, oval, oblique patch on the disc at the base, and a very 
broad oblique patch a little before the middle, extending from the middle of the disc almost to the 
lateral margin, yellow; the antenne black, joints 2-4 testaceous beneath ; legs and under surface bluish- 
black, the pro- and epipleurse (the median spot excepted) ceruleous. Head opaque, rugulosely punctured, 
deeply canaliculate; antenne with the four basal joints shining, the others opaque. Prothorax opaque, 
twice as broad as long, rather deeply arcuate-emarginate in front, the sides rapidly arcuately converging 
from the base, the base subtruncate on either side, the median lobe obtuse and somewhat broadly produced, 
the disc with a smooth, fine, impressed median line, becoming deeper behind, the surface with very 
minute, shallow, scattered punctures. Scutellum smooth. LElytra about three and a half times the 
length of, and at the base not wider than, the prothorax, broad oval, conjointly rounded at the apex; the 
disc moderately shining to beyond the middle, opaque at the apex, regularly convex, thickly, finely 
punctured, the punctures a little coarser and more irregular on the light-coloured parts, the suture 
smooth, not raised posteriorly; the margins moderately expanded, deflexed, obliquely converging — 
anteriorly, widest at about one-fourth from the base, punctured like the disc, opaque, the median — 
patch slightly shining, the exterior limb scarcely thickened. Beneath shining, very sparsely pubescent, 
almost smooth. 
Length 10, breadth 8 millim. 
Hab. Nicaragua, Chontales (Belt). 
One example. Closely allied to Mf. salvint and WM. xanthospila, but with different 
elytral markings; the elytra (2) much less broadly expanded at the sides, at the base 
not wider than the base of the prothorax, the margins punctured like the disc.
