New Genera and Species of Neotropical Curculionidae. 185 



almost parallel-sided, with a deep median furrow contimious with 

 that on the rostrum. Rostrum as long as broad, parallel-sided, 

 with a deep median furrow in the basal half only and a shallow 

 longitudinal impression on each side ; the interantennal area almost 

 flat transversely. Prothorax transverse, broadest at the base, 

 gradually narrowed to the apex, with the sides gently rounded; 

 the disk slightly flattened in the middle, with a shallow median 

 furrow almost reaching the apex and much deeper at the base; 

 the median furrow containing a narrow stripe of ovate scales, and 

 a very dense lateral stripe on each side of similar scales, the inter- 

 vening space thinly clothed with very narrow elongate scales, 

 lying transversely and sometimes intermingled with a few broad 

 ones; the setae erect at the sides, but recumbent on the disk. 

 Elytra shaped as in O. pudens Boh., the basal margins moderately 

 rounded; the striae shallow, with large round separated punctures, 

 the intervals not broader than the striae; the scales short ovate 

 or circular, not very dense, those on the basal half of intervals 1 to 3 

 or 4 much narrower, more or less setiform ; the numerous shorter 

 setae strongly curved or subrecumbent, the longer ones more raised 

 and suberect towards the sides and apex. 

 Length, 7-5-9 mm. ; brea^dth, 3-5^ mm. 



Barbados {J. Bo veil). 



Described from four specimens taken on Chrysohalanus 

 icaco. 



This species is very closely allied to G. pudens Boh., 

 which differs as follows : — The scales on the head are 

 circular; the lateral impressions on the rostrum are much 

 deeper; the prothorax is more narrowed in front, not 

 flattened on the disk and covered throughout with circular 

 scales, the median furrow is confined to the basal half 

 or obsolete, and the setae on the disk are quite erect; 

 on the elytra the intervals are broader than the striae and 

 covered right up to the suture with circular scales, all the 

 setae being erect. 



Genus Pseudocyphus Schaeff. (1905). 



This genus includes those forms of Platyomus which in 

 many collections stand under the MS. name of Metriomus 

 Jekel.
