180 PHYTOPHAGA. 
This insect has not hitherto been recorded from north of Brazil. In life, the 
numerous raised callosities on the elytra are of a brilliant metallic golden or golden- 
green, in contrast to the blackish or castaneous colour. of the dorsum. We have 
received four specimens from within our limits. 
3. Charidotis flavomarginata. (Tab. IX. fig. 21.) 
Broadly elliptic, very convex, shining, sanguineous; the prothorax and elytra bordered with piceous along 
the outer part of the disc, their expanded margins dilute flavous and subhyaliue ; the antenne, legs, and 
under surface (the inner half of the epipleura excepted) testaceous. Antenne short, not extending beyond 
the base of the prothorax, joint 3 very short, much shorter than, and not nearly so stout as, 2, 4 very 
little longer than 3, 5 and 6 subequal, longer than 4, 7-11 stout, 8-10 as broad as long, 11 twice as 
long as 10, acuminate. Prothorax broadly dilated at the sides and in front; the disc deeply, obliquely 
grooved at the base on either side of the very broadly truncated median lobe, and with some scattered 
distinct punctures at the sides behind. Scutellum very large, smooth. Elytra about two and one third 
times as long as, and at the sides forming a continuous outline with, the prothorax, deeply sinuate-_ 
emarginate at the base, and with prominent subangular humeri; the disc very convex, bifoveate at the 
base, hollowed behind the prominent humeral callus, and rather abruptly declivous behind and at the 
sides; with rows of moderately coarse, not very closely placed punctures (which become finer towards the 
suture) extending to the apex, the interstices smooth and almost flat; the margins only moderately 
expanded, becoming very narrow at the apex, smooth, and reticulate, separated from the disc by a row of 
very deep fovee. 
Length 44-44, breadth 34 millim. 
Hab. GuateMALA, Chacoj and La Tinta in Vera Paz (Champion). 
Three examples, all from the lower part of the Polochic Valley. This small species 
is perhaps nearest allied to C. erythrostigma. It has the fourth joint of the antenne 
very little longer than the third, it being shorter than in most of the allied forms. 
4. Charidotis erythrostigma, (Tab. IX. fig. 23.) 
Broadly elliptic, very convex, shining, black, the expanded margins of the prothorax and elytra dilute flavous 
and hyaline; the elytra with a common transverse yellowish-red patch before the middle—narrowing 
outwardly and reaching to the fifth interstice, and extending along the suture to the base; the legs and 
antenne flavo-testaceous ; the underside black, the ventral segments flavo-testaceous. Antenne short, 
not extending beyond the base of the prothorax, joint 3 very short, much shorter than, and not nearly so 
stout as, 2, 4-6 subequal, each much longer than 3, 7-11 stout, 8-10 as broad as long, 11 twice as long 
as 10, acuminate. Prothorax broadly dilated and reticulate at the sides and in front; the disc deeply 
obliquely grooved at the base on either side of the very broadly truncated median lobe and with some 
scattered distinct punctures at the sides behind. Scutellum very large, almost smooth. Elytra about two 
and a half times the length of, and at the sides forming a continuous outline with, the prothorax, deeply 
sinuate-emarginate at the base, and with prominent subangular humeri; the disc very convex, bifoveate 
at the base, hollowed behind the prominent humeral callus, and somewhat abruptly declivous towards 
the apex and at the sides, with rows of closely placed, deep, rather coarse punctures extending to the apex , 
the interstices smooth ; the margins only moderately expanded, becoming very narrow at the apex, smooth, 
and reticulate, separated from the disc by a row of very deep foves. 
Length 5, breadth 4 millim. 
Hab. Mexico, Cerro de Plumas (/ége). 
One example only of this very distinct species has been received. It is allied to the 
Brazilian C. rubrocincta and C. circumscripta, Boh., from both of which it differs in 
the common transverse yellowish-red patch on the elytra, and in having the punctures
