row of cinereous hairs extending from basal lobe to near middle, and 

 with two more or less distinct transverse fasciae composed of sparsely 

 placed, long, recumbent cinereous hairs arranged as follows : a broad 

 irregular one at middle, and a similar one covering the apical fourth, 

 there are also a few scattered hairs of the same color on the basal 

 third, and between the median and apical fasciae the surface i& 

 sparsely clothed with inconspicuous semi-erect black hairs; surface 

 finely and very irregularly punctate, and the intervals obsoletely 

 reticulate and shining. Abdomen beneath very sparsely, ocellate- 

 punctate, the punctures large, indistinct, open posteriorly, and from 

 each puncture arises a short, recumbent cinereous hair; intervals 

 finely and densely reticulate; last segment broadly obtusely rounded 

 at apex, the margin armed with a series of regularly placed, narrow, 

 parallel teeth, and the apical groove deep and following the outline 

 of the posterior margin. 



Length, 3 mm. ; width, 1.45 mm. 



Type locality. — Huachi (Beni Eiver), Bolivia. 



ry/^e.— Cat. No. 26984, U.S.N.M. 



Described from a single female collected at the type locality dur- 

 ing September, 1921. 



BRACHYS MOSITANA, new species ' 



Male. — Broadly oblong, two times as long as wide, broadly 

 rounded in front, and more acuminate behind, moderately shining 

 and sparsely pubescent, the pubescence forming three more or less 

 distinct fasciae on the elytra; head, pronotum, and scutellum pice- 

 ous, with strong aeneo-cupreous tinge; elj^tra cyaneous, with the 

 more densely pubescent areas feebly greenish; beneath piceous, 

 with a feeble aeneous reflection. 



Head feebly coiivex, broadly but feebly depressed behind the 

 epistoma, and without gibbosities on the vertex, broadly and rather 

 deeply longitudinally grooved from epistoma to the anterior part 

 of occiput, the groove becoming broader and more obsolete toward 

 epistoma; surface finely, obsoletelv reticulate, with a few fine punc- 

 tures on the occiput and near epistoma, the punctures A^ery sparsely 

 and irregularly spaced on the occiput, but becoming denser and 

 more regular at the epistoma, and from each puncture arises a 

 rather long semi-erect pale yellow hair, those on the occiput finer 

 and more recumbent; epistoma verj?^ narrow between the antennal 

 cavities, elevated, and not transversely carinate in front. Pronotum 

 moderately convex, two and one-half times as wide as long, slightly 

 narrower in front than behind, and widest at base ; sides feebly arcu- 

 ately attenuate from base to anterior angles (when viewed laterally 

 the margin is abruptly arcuate near the posterior angles for the 

 reception of the anterior legs) ; anterior margin truncate ; base trans-
