sulcus, at the middle of its length, in the males of this genus, is an 

 unobtrusive but rather decisive character. 



Paragarnia n. gen. 



This is the first of a series of genera having decussate and strongly, 

 internally dentate mandibles; many of the genera are monotypic, 

 so far as known at present. In Paragarnia the body is oval, 

 convex, glabrous and shining, the beak rather thick, moderately 

 arcuate and separated from the head by a fine deep line. The 

 antennae are slightly behind the middle, with short scape, the 

 funicle rather long and slender, with the first joint as long as the 

 next three, two to seven small and subequal, the club abrupt, 

 elongate-oval, densely pubescent, with very deep sutures and fully 

 as long as the preceding five joints. The prosternum is feebly 

 impressed, the coxae moderately separated, the femora simple and 

 subparallel and the tibiae rather slender, evenly rounded externally. 

 The prothorax is only feebly constricted apically and the scutellum 

 is small, oval, flat and in close contact with the pronotum and 

 elytra. The type is the following: 



Paragarnia atrolucens n. sp. — Evenly oval, deep black and shining throughout; 

 beak ( cf ) a little longer than the head and prothorax, very feebly tapering through- 

 out, not very slender, shining, moderately sculptured, discretely at base; antennae 

 rufo-piceous; prothorax a third wider than long, the sides feebly converging and 

 broadly, moderately arcuate, more so and more converging near the apex to the 

 short and laterally oblique tubulation, which is not quite half as wide as the base; 

 surface minutely, remotely punctulate, coarsely and rather closely punctured 

 and longitudinally subrugose at the sides; basal lobe small, gradual, not more 

 punctured and without lateral impressions, its apex with a small and feeble 

 sinus, fitting the scutellum, which is moderate and somewhat longer than wide; 

 elytra evenly oval, slightly elongate, only a little wider than the prothorax and 

 three-fourths longer, the humeri broadly rounded, not evidently prominent; 

 striae groove-like, fine and feebly punctulate suturally and coarser, deeper and 

 smoother laterally, not at all dilated at base; intervals only with remote, infinites- 

 imal punctulation; under surface rather strongly but loosely and unevenly 

 punctate, the abdomen very smooth, impressed at base medially and at the 

 middle of the fifth segment; legs picescent, finely, sparsely punctate and rather 

 short. Length 3.3-3.8 mm.; width 1.65-2.0 mm. Brazil (Santarem). Four 

 specimens. 



The antennae, scutellum, claws and mandibles will readily serve 

 to identify this species when discovered. 



Spolatia n. gen. 



With an outline and general structure of the body and scutellum 



resembling the preceding almost precisely, the type of this genus 



differs to an astonishing degree in the structure of the antennae, 



which are short, thick and extremely compact, the funicle merging
