longer and white at the base of each interval, in a longer post-scutellar line 

 on the first, and on all the intervals for a considerable distance behind the 

 middle and sometimes also at apex; under surface with the slender white 

 squamules sparse, larger and dense on the met-episterna and posterior parts 

 of the abdomen; beak short, thick, feebly arcuate, densely sculptured and 

 about four times as long as wide (cf), similar in length and three-fourths as 

 long as the prothorax but notably slender ( 9 ) ; sparsely squamulose and 

 feebly carinulate above in the male; eyes large, only a little more separated 

 below than above, where the squamose interspace is three-fifths as wide as 

 the beak (o 71 ), or three-fourths ( 9 ); head nude, finely, not densely punctate; 

 prothorax just visibly elongate (d 71 ), or a sixth wider than long (9), with 

 parallel and nearly straight sides, rapidly rounding at apical third to the 

 broad, truncate and subtubulate apex, which is almost two-thirds as wide 

 as the base, the basal lobe small, rounded; punctures very coarse, virtually 

 in mutual contact; scutellum small, parallel, longer than wide; elytra a 

 third to two-fifths longer than wide, very slightly wider than the prothorax 

 and three-fifths longer, the sides arcuately converging slightly posteriad, to 

 the broadly rounded apex, the humeri not prominent; grooves very abrupt, 

 coarse, deep and strongly punctate along the bottom; intervals but little 

 wider than the grooves, each with a single series of coarse and almost con- 

 tiguous punctures; abdomen finely punctate, without sexual modification. 

 Length 2.6-3.0 mm.; width 0.85-1.2 mm. Brazil (Chapada). May and 

 November. On flowers, in forest clearings. Abundant. Eleven specimens. 



solarii n. sp. 

 A — Body nearly similar but a little larger and stouter; beak in both sexes 

 relatively shorter and stouter, only three-fifths as long as the prothorax 

 or less in either sex, and, in the female, although thinner than in the male, 

 distinctly thicker than in the female of solarii; prothorax relatively 

 larger, nearly as long as wide in the male, much less distinctly narrower 

 than the elytra than in the same sex of solarii, the punctures similarly 

 very coarse and dense, partially confluent; elytra throughout nearly 

 similar. Length 3.1-3.2 mm.; width 1.3 mm. Brazil (Chapada — forest). 



Two specimens floricola n. subsp. 



B — Body nearly as in the preceding; beak (9) almost similar and much 

 thicker than in the female of solarii, but little over half as long as the 

 prothorax, the latter similar, but with the coarse punctures less dense, 

 being individually distinct in outline and slightly separated; elytra nearly 

 similar. Length 2.8 mm.; width 1.23 mm. Brazil (Chapada). On 



flowers in forest clearings. One female specimen discretus n. subsp. 



Form, coloration, vestiture and other characters nearly as in the preceding, but 

 a little larger and broader, subcylindric, the loose white squamules in single 

 series behind the middle of the elytra forming similarly a loose transverse 

 fascia, which, however, is narrower than in solarii and more widely separated 

 from the base, the denser white line basally on the first interval shorter; 

 beak still stouter and less than four times as long as wide, closely sculptured 

 and squamulose, the eyes more distant, separated by the full width of the 

 beak, the head more closely punctate; antennal club slightly smaller and 

 still more gradually formed; prothorax of similar form, but rather more 

 distinctly wider than long, the punctures not quite so coarse and more 

 crowded, in close mutual contact; median line finely smooth and subtumid, 

 wanting apically; elytra similar in general proportions and sculpture, but a 

 little broader; abdomen more closely squamulose throughout. Length 3.7 

 mm.; width 1.45 mm. Brazil (Chapada- — forest). November. One fe- 

 male silvestris n. sp.
