Brazilian Baring 495 



quadrate; elytra evidently less than three times as long as wide, equal in 

 width to the prothorax and but little more than one-half longer; sides 

 parallel, rapidly rounding but not obtuse at apex; uneven yellowish scales 

 large but slender, very sparse; striae coarse, deep, not very even, with rather 

 coarse punctures, each inclosing a shorter scale; intervals slightly convex, 

 with single series of moderate and very remote punctures; abdomen with 

 the first suture very fine and subobsolete, the last three conspicuously coarse 

 and deep; pygidium apparently a little longer in the male; lower tibial 

 ramus spiniform, porrect, extending beyond the tibial tip. Length 9.5-9.8 

 mm.; width 2.3-2.4 mm. Brazil (Santarem). Two specimens. 



spinifer n. sp. 



Body glabrous above; prothorax less elongate; elytral striae very fine and sharp, 

 having moderate but deep and well spaced punctures, which are much wider 

 than the striae and crenulating the sides of the intervals 3 



3 — Form elongate and convex, feebly narrowed posteriorly from the base of the 

 elytra, rufo-piceous in color and polished, the prothorax alutaceous; medial 

 line of the prosternum, intercoxal part of the mesosternum and the met- 

 episterna clothed with more or less dense yellowish scales; beak ( 9 ) a little 

 longer than the head and prothorax, moderately slender, finely, loosely 

 punctate, alutaceous, compressed behind the antennae, feebly arcuate, the 

 upper constriction at basal sixth bordered anteriorly by a small tubercle, 

 the lower, at basal fifth, deep and oblique; between the latter and the base 

 there is a large excavation at each side; antennae at four-sevenths, the scape 

 extending to the lower constriction, the remainder as described above; 

 prothorax one-half longer than wide; sides feebly arcuate, oblique anteriorly, 

 parallel in about basal half, the apex half as wide as the base; punctures 

 minute and sparse throughout, the median line not clearly impunctate but 

 feebly prominent by laterally oblique light; scutellum quadrate, slightly 

 convex; elytra about two and one-half times as long as wide, at the feebly 

 tumid humeri equal in width to the prothorax, nearly three-fourths longer, 

 the sides slightly oblique and nearly straight, gradually rounding behind; 

 striae extremely fine but sharp, with the punctures strong, deep and moder- 

 ately separated, deeper in the transverse basal concavity and very coarse 

 and deep posteriorly; single interstitial series composed of distant infinites- 

 imal punctures; pygidium flat, twice as wide as long and circularly rounded, 

 densely punctate; lower ramus of the anterior tibiae cylindric, not acute as 

 in the preceding species, extending as far as the femoral tip; tibiae elongate, 

 feebly sigmoid; terminal oblique concavity of the posterior deeply cleft on 

 the inner side. Length 9.3 mm.; width 2.35 mm. Brazil (Santarem). One 

 specimen distortus n. sp. 



Form, color, lustre and vestiture of the under surface as in the preceding, the 

 body smaller in size and more slender, still smaller in the female; beak 

 nearly similar, a little shorter in the female; prothorax shorter, two-fifths 

 ('9) to three-sevenths (c?) longer than wide, similar in outline, but with 

 the sides anteriorly more strongly oblique; sculpture similar; elytra also 

 similar, except that the basal impression is feeble and does not extend so far 

 toward the humeri, and the strial punctures are smaller; abdomen similar 

 in the sexes, strongly convex along the middle as usual; pygidium (d") 

 nearly as in the preceding but more convex and with a large median con- 

 cavity, or ( 9 ) similar in outline but rather smaller and more transverse, 

 with its surface even and flat; legs almost as in the preceding in both sexes. 

 Length 7.4-8.5 mm.; width 1.7-1.9 mm. Brazil (Santarem). Three 

 specimens ramifer n. sp.
