base. The prothorax is strongly tubulate, the elytra deeply grooved 

 and the upper and lower surfaces partially squamulose. The type 

 may be described as follows: 



Linogarnia suturalis n. sp. — Rhomboidal, rather convex, polished and deep 

 black throughout, the squamules white, sparse at the sides of the prothorax 

 apically and basally and more conspicuous at the base of all the strial intervals 

 and narrowly along the suture, becoming more diffused at apex: the punctures of 

 the under surface and legs bear each a distinct narrow white scale; beak nearly 

 as long as the elytra, rather smooth, shining, strongly and loosely sculptured and 

 sparsely squamulose at the sides basally; prothorax a fourth wider than long, 

 the sides moderately converging and nearly straight for three-fifths, then gradually 

 rounding to the large tubulation, which is half as wide as the base and a fifth or 

 sixth the total length, almost punctureless; surface very smooth, not at all 

 punctulate, the basal lobe very short, broad and gradual, having a few punctures 

 along its entire edge, without trace of lateral impressions; scutellum glabrous, 

 feebly convex, as long as wide and obtrapezoidal; elytra nearly a third longer 

 than wide, much wider than the prothorax and three-fourths longer, subtriangular, 

 with distinctly arcuate sides and rather narrowly rounded apex, the humeri 

 feebly prominent, though very broadly rounded; grooves deep, smooth; intervals 

 very smooth, except where squamulose; abdomen finely, loosely punctulate and 

 sparsely squamulose. Length 3.7 mm.; width 2.2 mm. Brazil (Rio de Janeiro). 

 November. One specimen. 



The partial squamulation of the surface will render this species 

 immediately recognizable among the allied glabrous genera. 



Tudeniaspis n. gen. 



In this genus the scutellum is of the same type as in the preceding, 

 but the mandibles differ much from those of the three preceding, 

 being prominent when closed and not decussate; they are however 

 strongly dentate on the inner margin of one or both. The body is 

 rather oblong-suboval, convex, subglabrous above, each of the 

 rather strong punctures of the under surface with a small narrow 

 white squamule. The beak is slender, very feebly arcuate, cylindric 

 and separated from the head by an abrupt deep groove, the antennae 

 submedial, somewhat slender, the first funicular joint about as long 

 as the next three, the club oval, rather abrupt and about as long 

 as the four preceding joints. The prosternum is somewhat deeply 

 channeled and the coxae moderately separated, the femora rather 

 inflated, simple, the tarsi as long as the tibiae, with the claws long, 

 straight and strongly connate at base. The prothorax is briefly 

 and not very abruptly subtubulate, and the elytra are grooved. 

 The dorsal abdominal segments, under the elytra, have each a 

 sublateral and marginal spot densely clothed with minute pale 

 brown squamulae, giving a velvety effect. There are two species 

 at hand as follows: 



Form not broadly oval, convex, shining and deep black; beak (9) slender,
