somewhat longer, more obtuse behind and with the oblique sides more 

 sinuate; pygidium more feebly and obtusely carinulate along the middle; 

 scales of the under surface much smaller, though broad in form, inconspicuous, 

 the metasternal punctures less coarse; fifth ventral with the margin thickened 

 medially in a way not noticeable in the preceding female. Length n.o mm.; 

 width 5.7 mm. Colombia. A single female from Desbrochers des Loges. 



scutellata n. sp. 



5 — Body with dark bronze or aeneous lustre 6 



Body bright blue or greenish-blue throughout 8 



6 — Beak shorter, thicker, more arcuate, tapering and punctate nearly as in 

 Cymatobaris; pronotum very coarsely and densely cribrate, the punctures 

 isolated basally; median impunctate line parallel, somewhat convex and 

 very well defined, though not attaining the apex. Form oblong-oval, shining; 

 beak (a 71 ) three-fourths as long as the prothorax, the punctures moderately 

 strong, separated, gradually fine and sparse distally, or ( 9 ) almost exactly 

 similar, though perhaps a trifle longer and even more coarsely punctate; 

 antennae medial (cf) or just visibly post-medial (9), of nearly normal 

 structure, the scape notably short, the club abrupt, thick and oval, less 

 pointed, as long as the three or four preceding joints, the scrobes very large, 

 oblique and cavernous, prolonged somewhat beyond the antennae; prothorax 

 very convex in lateral profile,, a fourth wider than long, the arcuate sides 

 becoming parallel basally, obliquely, feebly arcuate from behind the middle ; 

 apex not tubulate, much less than half as wide as the base; basal lobe nar- 

 rowly and feebly sinuate at apex; scutellum subquadrate, medially channeled 

 except at base; elytra a fourth longer than wide ( 9 ), a little longer (cf), 

 a fourth wider than the prothorax and nearly four-fifths longer; striae 

 catenulate, with very large, deep and elongate foveae; intervals throughout 

 with single series of coarse punctures; pygidium transversely oval, slightly 

 oblique, nearly flat in both sexes and very feebly subcarinate; scales of the 

 under surface small, at the bottom of very coarse and deep punctures and 

 very inconspicuous; male with a parallel impression in basal two-fifths of 

 the abdomen, the tip of the fifth segment entire, not liguliferously sinuate 

 as in the metallica section. Length 7.2-8.5 mm.; width 3.5-4.4 mm. Brazil 



(Chapada). October. Three specimens consessor n. sp. 



Beak less thick, subevenly cylindric and more nearly as in the metallica section; 



median regions of the pronotum with large impunctate area 7 



7 — Body oblong-suboval, shining, cupreo-aeneous; beak in both sexes as long as 

 the prothorax, cylindric, black, shining and finely, sparsely punctate, aeneous 

 and very coarsely punctate in less than basal half, feebly arcuate, sometimes 

 slightly swollen above basally; antennae medial, the club ovoidal, obtusely 

 pointed, abrupt and about as long as the four preceding joints; prothorax 

 strongly convex in lateral profile, two-fifths wider than long, the strongly 

 arcuate sides gradually becoming parallel posteriad; apex tubulate, less 

 than half as wide as the base; punctures very coarse and deep, unevenly 

 distributed but generally rather widely separated; post-medial vacant area 

 usually continued forward to the apex in a narrow smooth line; scutellum 

 subquadrate, unimpressed; elytra a fourth longer than wide, about a fourth 

 wider than the prothorax and twice as long; sides but feebly oblique; humeri 

 only slightly prominent; strial foveae deep but narrow and elongate, the 

 surface more or less rugose; punctures of the interstitial series coarse and 

 widely separated, decidedly small on the first two or three intervals; pygid- 

 ium very prominent along the median line, especially toward apex in the 

 male, the latter with the metasternum and basal part of the abdomen broadly 

 and shallowly impressed, the fifth segment with a very small, obtusely
