Brazilian Baring 461 



strongly divergent and well developed. Prothorax cylindric, the 

 basal lobe extremely short, transversely truncate, the scutellum 

 free, transversely quadrate, the elytra deeply grooved and the 

 pygidium short and semicircular, twice as wide as long, densely 

 punctured and impressed at each side. The fine distinct and entire 

 first ventral suture and generally smoother surface, also distinguish 

 the genus from the preceding. The type is the following: 



Neogivenius cylindroides n. sp — Cylindric, glabrous and rather strongly 

 shining, rufous in color throughout, the elytra more blackish; beak ( 9 ) slender, 

 a fourth longer than the head and prothorax, feebly tumid dorsally at base, 

 minutely, sparsely punctate, coarsely behind the antennae, which are at basal third, 

 rather slender, with abrupt oval, subequally segmented club, the scape about half 

 as long as the stem ; prothorax only very little wider than long, the parallel sides 

 straight, feebly inflated near the base, rapidly rounded near apical fourth, the 

 tubulation short and nearly two-thirds as wide as the base; punctures rather 

 coarse and unevenly close at the sides, then becoming almost as coarse but sepa- 

 rated by twice their diameters, abruptly much smaller and a little less sparse 

 near the smooth median line; elytra fully two-fifths longer than wide, at the 

 slightly prominent humeri evidently wider than the prothorax, not quite twice as 

 long; sides parallel, behind the middle at first gradually, then circularly, rounded; 

 grooves slightly and crenulately punctate, gradually moderately exarate distally; 

 intervals basally twice as wide as the grooves, but, medially, nearly three times, 

 with single series of very moderate shallow punctures; apices broadly rounded; 

 sternal punctures strong and sparse, each with a slender squamule; abdomen 

 finely, shallowly and very sparsely punctate throughout. Length 3.0 mm. ; width 

 1.2 mm. Argentina (Mendoza). A single specimen, sent by Desbrochers des 

 Loges. 



It is to be regretted that the male is not at hand, as it might 

 disclose some interesting characters. 



Anathaniops n. gen. 



In this genus the body is minute, very slender and subcylindric, 

 strongly sculptured and virtually glabrous, the beak thick, separated 

 by a moderate reentrant angle and strongly sculptured. Antennae 

 medial, short, the club elongate-oval, compressed, subequally seg- 

 mented and pubescent, about as long as the six preceding joints. 

 Prosternum moderately impressed along the middle, widely sepa- 

 rating the coxae, all of which are notably small, the tarsi slender and 

 the claws apparently connate at base. The prothorax is not in the 

 least tubulate at apex, the basal lobe very short, feeble and broadly 

 rounded, the scutellum very free, small, subquadrate and densely 

 sculptured, the elytra rather finely grooved, with asperate intervals, 

 the apices broadly rounded. Pygidium semicircular, densely punc- 

 tate, transversely tumid inferiorly. The first abdominal suture is 

 obliterated medially. The type is as follows: 



Anathaniops cylindrica n. sp. — Narrow, cylindric-suboval, convex, blackish- 

 piceous, the elytra just visibly paler, slightly shining; beak (cf) thick, nearly as
