422 Memoirs on the Coleoptera 



strial punctures are more close-set and the subapical umbones not tinged 

 with cupreous; pygidium nearly similar, with allowance for sex, being a 

 little smaller in the female; abdomen in the type not impressed at base, 

 the fifth segment with a very small rounded discal fovea near the apex, the 

 abdominal surface feebly cupreous medially. Length 4.7 mm.; width 2.7 

 mm. Panama. A single example, received from an unrecorded source 

 about thirty years ago minuens n. sp. 



10 — Body only moderately stout, rhombiform, polished, bright green or greenish- 

 blue, the pronotum brilliantly cupreous-red in apical half, extending nearly 

 to the base medially; large humeral and rather smaller apical areas on the 

 elytra — connected longitudinally at the sides — also deep cupreous-red; under 

 surface bright green, the beak, legs and fifth ventral bright cupreous; coppery 

 areas of the upper surface sharply defined; beak (o 71 ) feebly arcuate, thick, 

 compressed, strongly but sparsely punctate and distinctly longer than the 

 head and prothorax, or ( 9 ) similar but a little shorter; antennae at two- 

 thirds (cf), or four-sevenths (9), of the usual structure; prothorax feebly 

 convex in profile, but more rapidly declivo-convex apically, campanulate, 

 not quite one-half wider than long, the punctures very remote and fine but 

 impressed, especially in the male, and distinct; elytra as long as wide, with 

 very large and conspicuous humeral prominences, the sides behind them 

 strongly oblique, the apex moderately obtuse, individually rounded as usual; 

 fine striae very feebly impressed, finely but distinctly punctate, the first 

 coarsely in basal half; pygidium as usual; abdomen (o 71 ) impressed medio- 

 basally, the fovea of the fifth segment moderate, deep, fusco-pubescent and 

 scarcely wider than long, or ( 9 ) very feebly impressed medially at the apex 

 of the fifth segment. Length 6.0-6.25 mm.; width 3.6-4.0 mm. Mexico 

 (Vera Cruz). Two specimens magnificus Gyll. 



Body more elongate, otherwise very similar throughout, the coloration similar in 

 general character, except that the cupreous areas above are nubilously 

 limited, that of the pronotum medial, not extending to the sides except 

 narrowly and in very faint degree, those of the elytra similar in form and 

 extent but less sharply defined; prothorax a little narrower and more elon- 

 gate, the apical tubulation broader; head larger; elytra similar in form but 

 somewhat longer, and with the fine striae not impressed but sharply defined, 

 the punctures similar; pygidium similar in form and sculpture but notably 

 larger; fifth ventral segment with the nude shallow impression medially at 

 apex larger, feebler and less definite and also less finely punctate. General 

 color of the body less intense and more greenish. Length 6.7 mm.; width 

 4.0 mm. Nicaragua. One female example gemmulus n. sp. 



II — Outline oblong-oval, convex, polished, deep and pure blue throughout above, 

 violaceous by oblique light, the under surface and beak greenish, the legs 

 blue; beak (9) scarcely as long as the prothorax, thick, straight, slightly 

 bent at apex, not separated by an impression, rather strongly, sparsely 

 punctate; antennae at apical third, the funicle rather rapidly thicker distally, 

 the club short, oval, ogivally pointed, with deep sutures, its basal segment 

 polished and glabrous except at apex; prothorax two-fifths wider than long, 

 campanulate, the strongly arcuate sides gradually subparallel basally; tubu- 

 lation abrupt, three-sevenths as wide as the base, the basal lobe obtusely 

 subtruncate at apex; punctures sparse and minute though distinct, still 

 stronger on the lobe; scutellum with some distinct punctures basally, 

 equilatero-triangular to shorter; elytra about as long as wide, with con- 

 spicuous humeral prominences, the sides behind them oblique, feebly arcuate, 

 gradually and broadly rounding behind; striae very fine, not impressed, the 

 punctures lineiform but very distinct, those of the first not coarser; pygidium
