Brazilian Barin/e 447 



slightly longer than wide, but little longer than the three preceding 

 joints and abruptly formed. The prosternum is very narrowly and 

 deeply, evenly sulcate, the concavity gradually obsolete toward the 

 suture,' where the surface becomes anteriorly cuspidate, the coxae 

 remote, separated by much more than their own width, the lobe 

 prominent but nearly twice as wide as long, unimpressed and feebly, 

 medially sinuate at apex. The prothorax is gradually tubulate, 

 the basal lobe rather prominent, rounded, the scutellum flat, semi- 

 free and somewhat broadly ogival, the elytra finely but sharply, 

 deeply grooved and the pygidium small, rough and semicircular. 

 The first ventral suture is wholly wanting medially. The type is as 

 follows : 



Linoma lustrans n. sp — Elongate, narrowly suboval, convex, polished, glabrous 

 and deep black; beak (<?) slender, moderately arcuate, closely punctured and 

 as long as the prothorax, or ( 9 ) very slender, more arcuate, less sculptured and 

 as long as the head and prothorax, the latter a fourth wider than long, the sides 

 subparallel and feebly arcuate, gradually moderately rounded beyond the middle 

 to the tubulation, which is somewhat more than half as wide as the base; punc- 

 tures rather small but deep, well separated, a little coarser but only slightly 

 less sparse laterally, the impunctate median line clearly defined; elytra evenly 

 oval, a third longer than wide, at the small and slightly tumid humeri fully a 

 fourth wider than the prothorax, nearly two and one-half times as long; surface 

 even not at all undulated, the grooves punctured, the punctures bearing each an 

 extremely small fine squamule, coarse but not exarate apically, the intervals 

 between three and four times as wide as the grooves, with single series of remote 

 and infinitesimal punctules; under surface with moderately coarse, the abdomen 

 with very fine, sparse punctures, the latter not distinctly impressed at base in 

 the male. Length 2.65-2.75 mm.; width 1.1-1.15 mm. Brazil (Chapada— 

 forest). June to September. Three specimens. 



The evenly parallel form of the very narrow prosternal sulcus, 

 widely separated coxee and slender beak, with very short antennal 

 club, will distinguish this species from any typical Heterosternus. 



Linomaspis n. gen. 



In this genus, which very well serves to connect the Pseudobarid 

 series with Ampeloglypter, the body is rather elongate, very obtuse 

 behind, with narrower subtubulate prothorax, and with sculpture 

 of the under surface differing very much from that of Heterosternus 

 and Linoma, the punctures being smaller but very deep and close- 

 set. The beak is moderately thick, cylindric, closely sculptured, 

 feebly arcuate and separated by a narrow shallow sulcus. Antennse 

 submedial, the first funicular joint about as long as the next three, 

 the club narrow, elongate-oval, longer than the preceding four 

 joints, with very strong sutures and with the basal segment almost 

 half the mass. The prosternum is moderately but regularly canal- 

 ate, the posterior lobe large, not impressed and very densely and
