long as the head and prothorax, evenly and feebly arcuate; prothorax a sixth 

 wider than long, the subparallel sides nearly straight, gradually rounding and 

 moderately oblique beyond about the middle; apex four-sevenths as wide as the 

 base; punctures coarse and dense, gradually less coarse and slightly separated 

 medially, with a narrow smooth median line; elytra fully four-fifths longer than 

 wide, barely visibly wider than the prothorax and distinctly more than twice as 

 long, the sides parallel and straight, gradually rounding behind, rather obtuse 

 at apex, the humeral swellings wanting; grooves finely, catenulately punctate 

 basally, gradually somewhat coarser distally; intervals with single series of 

 moderate asperate punctures; sterna coarsely, densely punctate. Length 1.85 

 mm.; width 0.65 mm. Brazil (Santarem). One specimen. 



While belonging to the Pseudobarid section, this must be regarded 

 as a peculiarly distinct genus. 



Lupulina n. gen. 



The body in this genus is regularly oval, convex, shining and 

 glabrous, the beak notably thick, strongly curved and feebly sculp- 

 tured, separated by a moderate reentrant angle. Antennae short, 

 submedial, the funicular joints compact, gradually increasing, so 

 that the outline merges gradually into that of the ovoidal and 

 densely pubescent club, which is longer than the preceding six 

 joints and subequally segmented. Prosternum with a wide and 

 deep, straight shining canal, the coxae large, separated by a little 

 less than their width, the posterior lobe moderate and evenly, 

 circularly rounded. The legs are moderate, strongly, densely 

 punctate, the femora somewhat bent downward distally, mutic, the 

 middle femora with a dense fringe beneath in the male, the tarsi 

 moderate, slender, with connate claws. Prothorax faintly sub- 

 tubulate at apex, the basal lobe very small, short and feebly sinuate, 

 the scutellum widely free, subquadrate, impressed and roughly 

 sculptured medially, the elytra with the grooves moderate, but 

 rapidly very coarse basally and not attaining the basal margin, 

 coarser but not exarate distally; the apex of each elytron has a 

 small anguliform tubercle, corresponding to the angulation in the 

 subgenus Microcraptus. Pygidium small, transversely rounded and 

 moderately convex, densely punctured as usual. First ventral 

 suture obsolete medially. There are two species at hand as follows: 



Form oval, strongly convex, polished, black and faintly subaeneous; beak (c?) 

 very thick, a little longer than the prothorax, the upper contour almost 

 semicircular in profile, the surface very shining, minutely and sparsely 

 punctulate throughout, very smooth, not at all compressed; antennae 

 piceous; prothorax nearly a third wider than long, the sides feebly converging 

 and moderately, subevenly arcuate from base to the feeble constriction 

 extending across the dorsal surface; apex rather more than half as wide as 

 the base; punctures laterad rather coarse, very deep, even and not quite in 

 mutual contact, gradually less coarse but deep and separated by about 

 their own diameters medially, without trace of smooth line; scutellum well
