the white vestiture nearly similar throughout; beak (9) very slender, 

 smooth distally, feebly arcuate, distinctly longer than in the female of 

 angusta and nearly a third longer than the prothorax; antennae submedial; 

 prothorax fully as long as wide, in outline nearly as in the preceding, the 

 sculpture almost similar, except that the punctures are a little smaller and 

 still sparser, separated by more than twice their diameters; elytra narrower, 

 three-fourths longer than wide, not evidently wider than the prothorax and 

 somewhat less than twice as long; striae still finer, the interstitial series 

 almost similar. Length i. 25-1 .4 mm.; width 0.35-0.4 mm. Brazil (Cha- 



pada — forest). May and August. Two specimens subtilis n. sp. 



Form broader, more oval, larger in size, the vestiture of slender white squamules 

 nearly similar; integuments black, shining, the legs short, slender and black; 

 beak ( 9 ) very slender, cylindric, not evidently tumid dorsally at base, 

 distinctly and evenly arcuate, black, finely punctate, smooth distally and 

 as long as the prothorax; antennae medial and nearly black; prothorax 

 slightly shorter than wide, the sides subevenly and moderately arcuate, 

 becoming parallel basally; punctures rather coarse but shallow, separated 

 by a little more than their diameters, the smooth median line narrow; elytra 

 very obtusely suboval, less than one-half longer than wide, evidently wider 

 than the prothorax and twice as long, the apex very obtusely rounded, the 

 sutural angle only very obsoletely reentrant; humeral swelling subobsolete; 

 striae fine but deep, remotely punctate; intervals with single series of minute 

 but very evident, well separated punctures; abdomen finely, very sparsely 

 punctate. Length 1.7 mm.; width 0.7 mm. Brazil (Chapada). January. 

 One female specimen pistorella n. sp. 



Species of this genus are, in all probability, among the smallest 

 of the Brazilian Barinae; they all occur in flowers, so far as known. 



Pseudotorcus n. gen. 



In this genus, which is allied somewhat to Sibariops, but with 

 more rigidly cylindric body, the beak in the female, the only known 

 sex, is very slender, evenly cylindric and nearly smooth, separated 

 from the head by a fine and somewhat feeble sulcus and rather 

 strongly, evenly arcuate. Antennae medial, slender, the first funic- 

 ular joint as long as the next two, the outer joints scarcely dilated, 

 the club rather abrupt, oval, as long as the four preceding joints 

 and with its basal segment not quite hal f the mass. The prosternum 

 is flat, the transverse fine constriction at a long distance from the 

 apex, the coxae somewhat large and approximate, separated by 

 only about a fourth their width. The legs are of the usual struc- 

 ture, the prothorax cylindric, not tubulate at apex, the basal lobe 

 extremely short, broadly arcuate and almost obsolete, the scutellum 

 free, subquadrate and glabrous and the elytra finely striate. The 

 type is the following: 



Pseudotorcus lustralis n. sp. — Rigidly parallel, convex and cylindric, strongly 

 shining and black, the legs dark rufous; squamules slender, white, very fine and 

 sparse, rather close and more distinct laterally on the pronotum, a little coarser, 

 somewhat conspicuous and in single or partially confused interstitial lines on the 

 elytra, narrow and sparse beneath, broader and dense at the sides of the hind
