Brazilian Baring 3 6 7 



lobe broadly truncate at the middle coxae. The legs are moderately 

 long, the femora mutic. The prothorax is gradually tubulate, with 

 small and feeble, truncate basal lobe, the scutellum free, quadrate, 

 somewhat convex and very minutely, sparsely setulose in -electa, 

 smaller and longitudinally sulcate in fastidiosa; the elytra have 

 coarse, deep and very sharply marked, moderately punctate grooves. 

 The pygidium is very small, vertical and is partially covered by the 

 elytra in the female. The two species now known are as follows: 



Body moderately stout and rhombic-oval, convex, shining and deep black, the 

 pronotum just visibly picescent, feebly alutaceous, with a few fine squamules 

 at the sides of the apex, also along the basal margin at the sides and medially; 

 on the elytra the larger white lineiform squamules are very remotely disposed, 

 but are close narrowly along the suture, except posteriorly and along the 

 base, the intervals each with a single series of fine, dark brown squamules; 

 under surface throughout with broader and well separated scales; beak ( 9 ) 

 a fourth longer than the head and prothorax, evenly arcuate, the keel oc- 

 cupying more than basal fourth, flat at the sides and squamulose, the portion 

 beyond very slender, evenly cylindric and smooth; antennae blackish, 

 between basal fourth and third at the end of the keel, slender, with short 

 scape, the first funicular joint as long as the next two, the outer joints sub- 

 quadrate, the club moderate, evenly oval and abrupt; prothorax a third 

 wider than long, the sides evenly and strongly arcuate, becoming subparallel 

 only at extreme base, the tubulation rather more than half as wide as the 

 base- punctures rather coarse but more or less widely separated, the smooth 

 median line entire; elytra a third longer than wide, a fourth wider than the 

 prothorax and between two and three times as long, the oblique sides broadly 

 arcuate, the apex evenly and somewhat obtusely rounded; humeri not 

 prominent, obliquely rectilinear basally; grooves not quite half as wide as 

 the intervals, which have single series of distinct and well separated punctures; 

 abdomen strongly convex, the first suture distinct; pygidium small, vertical 

 broadly rounded, densely punctate and half covered by the elytra. Length 

 40 mm.; width 2.0 mm. Brazil (Chapada). November. On flowers. 



One specimen electa n " S P" 



Body nearly similar but more slender, convex, shining and deep black throughout 

 the vestiture nearly similar; beak (cf) distinctly longer than the head and 

 prothorax, evenly, moderately arcuate, somewhat slender beyond the keel, 

 strongly sculptured and partially squamulose; antennae near basal third, 

 shorter than in the preceding and with smaller and more narrowly oval club, 

 the first funicular joint as long as the next four; prothorax a fourth wider 

 than long, the sides feebly convergent and scarcely arcuate, rounding ante- 

 riorly, the tubulation more than half as wide as the base; punctures nearly 

 similar; scutellum smaller, narrower and deeply channeled; elytra one-half 

 longer than wide, only a fifth wider than the prothorax and two and one-half 

 times as long, the outline somewhat as in the preceding ; grooves generally more 

 than half as wide as the intervals, the punctures of which are more remote; 

 pygidium vertical, semicircular, densely punctate; fifth ventral very feebly 

 impressed along the median line. Length 2.8 mm.; width 1.2 mm. Brazil 

 (Chapada— forest). November. One specimen fastidiosa n. sp. 



The peculiar keel-like basal crest of the beak is similar in the 

 sexes; its anterior end is slightly more prominent but obtuse.
