punctate. Length 3.0-3.4 mm.; width 1.5-1.7 mm. Brazil (Chapada — forest). 

 November. Eight specimens. 



The sexual characters in this species are very slight, amounting 

 only to a slight difference in the thickness of the beak and third 

 anterior tarsal joint. The abdomen sometimes has a very feeble 

 impression along the median line, but this may occur in either sex 

 and there is absolutely no apparent sexual modification of the 

 prosternum. 



Peclavia n. gen. 



This is another very peculiar but monotypic genus. The body 

 is almost evenly elliptic, polished and with slender erect dark 

 bristling squamules, loosely unseriate on the elytra and very small, 

 sparse, whitish, decumbent and inconspicuous beneath. The beak 

 is very slender, straight, smooth and somewhat flattened in apical 

 half, bent at the middle and thence gradually thicker, nearly straight 

 and closely punctured to the base, not separated from the strongly 

 convex head by a transverse impression. The mandibles are very 

 small, straight within, forming a right angle when closed. The 

 antennae are at two-fifths, slender, the funicle loose, with all the 

 joints at least as long as wide, the first almost as long as the next 

 three, the second also somewhat elongate, the club small, abrupt, 

 evenly oval and somewhat longer than the three preceding joints; 

 the prosternum rather widely separates the coxae and is moderately 

 deeply sulcate, the sides of the sulcus obtusely prominent, gradually 

 a little more so toward the coxae and closely punctate. The pro- 

 thorax is without trace of apical tubulation, the elytra coarsely 

 grooved and the hind tibiae slender and much shorter than the loosely 

 punctured femora. The type is as follows: 



Peclavia hispidicollis n. sp. — Oval, deep black and polished; beak as long as 

 the head and prothorax; antennae very slender, dark red-brown; prothorax fully 

 a third wider than long, the sides broadly arcuate, more oblique anteriorly and 

 subparallel toward base, the truncate apex less than half as wide as the base; 

 punctures strong, deep and separated by about twice their diameters, coarser 

 but only a little closer laterally, the erect hairs rather long and bristling; basal 

 lobe small, with the truncate apex medially sinuate; scutellum obtrapezoidal, 

 flat, one-half longer than wide, free; elytra evenly and broadly elliptic, with 

 somewhat strongly rounded apex, distinctly wider than the prothorax and about 

 twice as long, the humeri slightly swollen but not prominent, oblique basally; 

 grooves deep, abrupt, distinctly punctured along the bottom, half as wide as the 

 inner intervals but two-thirds as wide as the outer; single interstitial series 

 composed of rather small, well separated punctures; abdomen strongly, evenly 

 convex in the type, with moderate and slightly separated punctures. Length 

 3.8 mm.; width 2.1 mm. Brazil (Santarem). One specimen — probably female. 



Easily recognizable by the numerous erect bristling hairs, almost 

 evenly elliptic outline, convex surface and coarse elytral grooves.
