front; the entire surface (the suture excepted) thickly, moderately coursely, almost uniformly punctured. 
Beneath subglabrous, almost smooth. 
Length, 3, 74, breadth 64 millim.; 9, length 94, breadth 73 millim. 
Hab. Costa Rica (Van Patten). 
Four examples, two of each sex. 
a. The elytra marked as in the type; the under surface obscure ferruginous; the basal joints of the antenna 
above and beneath and the legs testaceous. 
Hab. Panama, Bugaba (Champion). ‘Two male specimens. 
B. The elytra immaculate, flavo-testaceous, testaceous, or ferruginous, the suture usually more or less infuscate 
anteriorly ; the prothorax sometimes with a narrow median vitta; the under surface and legs varying in ~ 
colour from black to testaceous. (Fig. 14.) . 
Length, ¢, 7-74, breadth 6--64 millim.; 2, length 84-93, breadth 63-73 millim. 
Hab. Costa Rica (Rogers, Van Patten); Panama, Bugaba, Volcan de Chiriqui | 
(Champion), Panama city (Conradt). Twelve examples, including both sexes. 
. This insect is very closely allied to M. cewruleonotata, and it is perhaps not really 
distinct from that species (of which I have only seen a single example); but the 
punctuation of the elytra is very much finer, and the prothorax has the sides straighter 
behind. The spotted and the immaculate forms have been received from the same 
localities, and I do not hesitate to put them together; the latter closely resembles 
M. suturalis, Boh., from Cayenne, but it has the elytra more uniformly punctured. 
The colour of the under surface and legs is variable. MU. varians, Boh., from Cayenne 
&c., is an allied form, specimens of which occur with the elytral spots almost obliterated. 
We figure a pair of the typical form from Costa Rica, and a male of the unspotted 
variety from Bugaba. 
14. Mesomphalia zneovittata. (Tab. VI. fig. 15, ¢ .) 
3. Rotundate, moderately convex, slightly shining; the head and prothorax testaceous, the latter with a 
broad median vitta extending from the base to the apex and narrowing anteriorly, and an oblong patch 
midway between this and the lateral margin, eneous, the margins a little more dilute and dotted with 
fuscous ; the scutellum eneous; the elytra flavo-testaceous, each with two broad eneous vittew, which 
become confluent posteriorly—the inner one constricted before the middle and not reaching the base, the 
outer one sinuous, occupying a considerable portion of the expanded margin, and extending over the 
humeral callus to the base,—and the suture nearly to the apex—broadly anteriorly, narrowly behind— 
seneous ; the antenne black, with the three basal joints, and the fourth and fifth beneath, testaceous ; 
the legs testaceous; the underside black. Head deeply canaliculate, rugulosely punctured; antenne 
rather stout, extending a little beyond the base of the prothorax, the four basal joints shining, the others 
opaque. Prothorax twice as broad as long, rather feebly arcuate-emarginate in front, the sides rapidly 
arcuately converging from the base, obliquely so anteriorly, the base truncate on either side, the median 
lobe obtuse and moderately produced ; the dise sparsely, very finely punctate, depressed in the middle 
behind, and with a very fine median line, which is deeply impressed at the base; the margins dull, 
almost smooth, rather concave, deeply foveate behind the middle. Scutellum smooth, moderately large. 
Elytra more than three times the length of, and in the widest part about one half broader than, the 
prothorax, at the base scarcely broader than it, conjointly rounded at the apex; the disc moderately 
gibbous before the middle; the margins broadly expanded, deflexed, rounded and widest before the
