1 88 Memoirs on the Coleoptera 



have failed to note this character in corvidus. It seems to be 

 wholly wanting in the first section. 



Ternova n. gen. 



In this genus the body is narrowly suboval and convex, with 

 partially glabrous surface, the beak long and very strongly arcuate, 

 especially toward base, slightly compressed, smooth above and 

 loosely and discretely but not coarsely punctate at the sides, 

 separated from the head by a feeble sulcus, the mandibles very 

 feebly overlapping, arcuate externally, slightly dentate internally 

 near the base and prominent when closed. Antennae medial, 

 slender, the first funicular joint nearly as long as the next three, 

 the second and third both somewhat elongate, the club moderate, 

 slightly abrupt and evenly oval. The prosternum has a deep 

 narrow elongate-oval glabrous excavation, the coxae separated by 

 barely more than a fourth of their width. The femora are not 

 inflated, simple, and the tarsal claws are thick, free and widely 

 diverging. The type and only known species is the following: 



Ternova tripartita n. sp. — Narrowly suboval, deep black, the pronotum very 

 smooth, polished and glabrous, excepting a few pale squamules forming a regular 

 series along the base laterally, the elytra rather closely and evenly clothed with 

 dark brown squamules, a few whitish along the base and others forming a narrow 

 dense vitta along the suture; under surface with dense whitish scales throughout; 

 beak (d") slender, strongly arcuate and about as long as the elytra, the antennae 

 piceous; prothorax a fourth wider than long, the sides moderately converging, 

 broadly, subevenly arcuate to the abrupt and nearly smooth apical tubulation, 

 which is more than half as wide as the base, the latter with a fine acutely beaded 

 margin throughout the width, but thicker along the short obtuse median lobe; 

 surface with remote and infinitesimal punctules; scutellum slightly wider than 

 long, subglabrous, broadly emarginate at apex; elytra two-fifths longer than 

 wide, evidently wider than the prothorax and about twice as long, narrowly 

 parabolic, the sides from above feebly sinuate near apical fourth; humeri rounded 

 but somewhat prominent, glabrous and shining; striae deeply grooved, a third as 

 wide as the intervals, which are flat, somewhat strongly and unevenly punctate; 

 male with the abdomen rather deeply impressed and less squamose medio-basally, 

 the prosternum with an extremely short dentiform spine before each coxa. Length 

 3.4 mm.; width 1.6 mm. Brazil (Chapada — forest). October. One example. 



Easily known by the peculiar vestiture, glabrous and basally 

 margined pronotum and by many other special features. 



Linonotus Csy. 



This genus was founded upon a species supposed to be from 

 Texas, which proves to have been very erroneously labeled and 

 really an inhabitant of the southern Brazilian coast regions, whence 

 I now have an ample series from Rio de Janeiro. The genus is 

 essentially of the South American tropics. The body is rhomboid-
