496 Memoirs on the Coleoptera 



4 — Body brownish-rufous, the general outline, convexity, lustre, sculpture and 

 scales of the under surface as in the two preceding; beak quite different, 

 more slender, evenly cylindric from base to apex, not constricted near the 

 base, evenly and moderately arcuate, polished and subimpunctate and very 

 much longer than the head and prothorax in both sexes; antennae rather 

 long, slender and submedial, nearly similar in structure; head with a trans- 

 verse fovea between the eyes at the base of the beak; prothorax a third to 

 two-fifths longer than wide, the sides feebly arcuate, parallel in basal, and 

 feebly oblique in apical, half; apex much more than half as wide as the base; 

 punctures very minute and remote throughout; scutellum smaller, narrowed 

 toward base, shining and shallowly concave; elytra rather more than two 

 and one-half times as long as wide, at the humeri just visibly wider than the 

 prothorax, about twice as long; sides barely visibly oblique, very gradually 

 arcuate and convergent posteriad to the very narrowly obtuse apex; surface, 

 striae, punctures and intervals throughout very nearly as in distortus, the 

 intervals relatively less broad; pygidium semicircular and feebly convex, 

 finely, not very densely punctate; legs slender and of the usual structure, 

 except that the anterior femora do not have the lower ramus near the apex, 

 but a small acute tooth in the same position. Length 7.4-7.8 mm.; width 

 1.85-2.0 mm. Brazil (Chapada — forest). November. Three specimens. 



subglaber n. sp. 



In the smallest of the three specimens of subglaber, the pygidium 

 seems to be a trifle smaller than in the other two, and this may 

 therefore be the female, but sexual modifications can be said to be 

 virtually unobservable. 



It is difficult to believe that so singular a genus as this, composed 

 of moderately large and rather numerous species, evidently widely 

 diffused over the neotropics, can have been overlooked by all former 

 authors, but I am unable to discover it in the literature. Lichnus 

 Lac, is very different in being rather coarsely and closely punctate, 

 with the antennal scape attaining the eyes, and in having the 

 prothorax rapidly narrowed anteriorly, and, in Lis pod emus Lac, 

 the pygidium is covered by the elytra. 



Paralichnus n. gen. 



The type of this genus is a somewhat conspicuous black glabrous 

 species, with bright rufous prothorax and rather coarse but sparse 

 sculpture. The beak is moderately thick, arcuate, cylindric and 

 separated from the head by a feeble impression, having medially 

 the usual small fovea. Antennae between basal third and fourth, 

 the scape short, barely longer than the club and virtually attaining 

 the eye, the first funicular joint as long as the next three, the club 

 somewhat abrupt, evenly oval, pubescent and with rather large 

 basal segment. Prosternum flat, separating the coxee by scarcely 

 a third of their width and transversely subrectilinearly truncate 

 behind, the intercoxal suture fine but very distinct. Prothorax 

 shorter than wide, not tubulate at apex and with small, very short
