Brazilian Baring 265 



tibial width, the presternum with two extremely minute angular ante-coxal 

 tubercles, the canal dilated at apex and base, very fine medially; in the 

 female it is broad, shallow and parallel. Length 5.5-6.0 mm.; width 2.8-3.1 

 mm. Brazil (Santarem). The female is from an unknown region and was 

 sent by Desbrochers des Loges rubricollis n. sp. 



There seems to be scarcely a doubt that the male and female 

 described as rubricollis belong to the same species, although the 

 sexual differences are unusual. Possibly bifasciatus, from Rio de 

 Janeiro, a rather large species, may have been previously described. 



Dactylocrepis Schon. 



In this genus the body is elongate and subrhombic, glabrous, 

 smooth and shining, the beak long, slender, evenly arcuate and 

 more or less compressed basally, the antennae slender to slightly 

 thickened, never with the first funicular joint relatively so elongate 

 as in the preceding, the club long, slender and gradually sharply 

 pointed and subequally segmented by the distinct sutures. The 

 prosternum in the male, the only sex known to me, is shallowly 

 canalate, the canal parallel or gradually broadening but not deeper 

 posteriorly between the wide, erect and strongly compressed tri- 

 angular ante-coxal plates, a form feebly suggested in Dimesus, the 

 coxa? well separated. The legs are long, with rather slender femora, 

 long straight tibiae and notably slender tarsi, the anterior sub- 

 quadrately dilated and flabellate, with feather-like erect black 

 vestiture at the sides, the third joint very peculiar, the rectangular 

 emargination extending nearly to the base, the lobes long, slender 

 and parallel; the anterior tibise of the male have a long dense 

 internal fringe of fine hairs. The prothorax is almost exactly as 

 in Dimesus, the scutellum subquadrate and free, the elytra with 

 fine subobsolete striation, prominent humeri and very prominent 

 subapical discal elevations, the striation at apex coarse, deep and 

 distorted. The species known to me are the following: 



Antenna; blackish, only moderately long, the first two funicular joints equal in 

 length and moderately elongate, the outer joints as wide as long. Body 

 highly polished, the elytra gradually toward the sides, and the legs, rufous; 

 beak (d>) two-thirds as long as the body, rather strongly arcuate, moderately 

 compressed, somewhat finely, sparsely punctate, more minutely and closely 

 so distally, where the diameter is gradually reduced; antennse at apical 

 third, the long rufescent scape extending two-thirds to the eye; prothorax 

 nearly as long as wide, the sides feebly convergent and slightly arcuate, 

 gradually broadly rounding anteriad to the tubulation, which is less than 

 half as wide as the base, the latter gradually broadly lobed and with fine 

 eroded marginal line medially; scutellum flat; elytra slightly wider than 

 the prothorax and evidently less than twice as long; striae, except apically, 

 very fine and feeble and with feeble distinct undilated punctures, the gently 

 oblique sides very feebly arcuate, the apex obtusely rounded; under surface 

 finely, remotely punctulate, the abdomen (d") very shallowly and widely
