New Genera and Species of Neotropical Curculionidae. 187 



deep separated punctures, stria 9 being markedly deeper than the 

 others ; the intervals gently convex and all of equal height and even, 

 with a well-marked transverse impression on each side before the 

 apex ; the scales broadly ovate or subcircular and overlapping, the 

 setae short, flattened and recumbent. 

 Length, 7-12 mm. ; breadth, 3-5-5 mm. 



Brazil : Obydos (type). British Guiana. 



Described from twenty-one specimens. 



This species is easily recognisable by its very characteristic 

 pattern from its nearest allies Ps. [Cyphus) ejfusiis Pasc. 

 and Ps. {Platyom.us) atrosignatus Lucas (of which Cyphus 

 sigillatus Pasc. is a synonym), and in conjunction with the 

 next species they form a small group presenting the following 

 characters: — Head very broad, forehead steeply sloping; 

 rostrum short and much narrowed to the apex ; prothorax 

 with a broad transverse depression occupying the posterior 

 fourth. 



I have retained for this species Dej can's manuscript 

 name, which has been generally applied to it in collections. 



Pseudocyphus sellatus, sp. n. (Plate III, fig. 9.) 



^JO. Integument black, with dense creamy-white scaling, which 

 is tinged -with buff on the forehead, rostrum, antennae and the 

 apical half of the tibiae ; the elytra with a common broad dentate 

 brown band behind the middle, extending on each side as far as 

 stria 8, its anterior margin almost on a level transversely on intervals 

 4, 6, 7, 8, projecting slightly forwards on 3 and 5, and deeply indented 

 on 1 and 2 — the hind margin nearly level on ints. 2, 3, 4, 6, shallowly 

 indented on 5, 7, 8. and projecting backwards along the suture ; a 

 small browTi spot near the base on int. 4, which is sometimes pro- 

 duced obliquely backwards on to 5, another a little further from the 

 base on the suture, and a narrow sinuous transverse brown line 

 between striae 3 and 9 just above the posterior callus. 



The structural characters are almost identical witli those in Ps. 

 tnarmoraius, sp. n., except in the following particulars : — The basal 

 impression on the prothorax is deeper, the anterior part being more 

 strongly wrinkled laterally, so that the wrinkles are clearly visible 

 through the scaling ; the elytra have the shoulders more prominent 

 laterally; and the 7th tergite in the ^ is broadly truncate at the 

 apex, whereas in Ps. martnoratus it is evenly curved. 



Length, 9-10-5 mm. ; breadth, 4-5 mm. 



Brazil : Bahia.
