24 PROCEEDIITGS OF THE NATIONAL MUSEUM vol.89 



Material examined. — Six specimens from Hispaniola, 14 specimens 

 from Puerto Eico, two specimens from Vieques Island, and a single 

 specimen from Trinidad, the last received for study from the British 

 Museum by kindness of Mr. Arrow. 



It is possible that A. tenehrosus Arrow is a synonym of A. picipes 

 Fleutiaux and Salle, but becavise of the lack of authentic material of 

 the latter I prefer to list the material before me under the younger 

 but certain name. 



11. ATAENIUS SUBOPACUS, new species 



Piceous, very feebly shining, front of head, anterior margin of 

 pronotum, and legs rather bright castaneous, antennae and trophi pale. 

 Anterior margin of head bluntly angulate each side of the shallow 

 median emargination, front finely, transversely rugulose, vertex highly 

 polished, sparsely and not coarsely punctured, the punctures slightly 

 more dense at sides. Pronotum with marginal setae fine and rather 

 sparsely placed, esjDecially across base, marginal groove entire, pos- 

 terior angles almost effaced. Surface subopaque, densely and moder- 

 ately coarsely punctured, the punctures only slightly sparser at 

 anterior portion of disk. Eiytral striae fine but rather deep, strial 

 punctures not conspicuous, intervals almost flat, each set with two 

 rows of closely set punctures adjacent to the striae. Each puncture 

 bears a minute seta. Lateral margin rather blunt, epipleura opaque. 

 Pygidial carina with fine and acute cusp, which is continued onto the 

 pygidium as a fine longitudinal carina reaching two-thirds to apical 

 margin. Metasternum somewhat shining, finely and densely sculp- 

 tured on extreme lateral area, median area somewhat deepened along 

 groove, sparsely and rather coarsely punctured, median groove deep, 

 abruptly terminated anteriorly. Abdominal sternites coarsely punc- 

 tured, densely at sides, sparsely along median line, basal transverse row 

 of pits on each sternite fine and distinct. Anterior femur with peri- 

 marginal groove, surface coarsely, evenly, and moderately densely 

 punctured. Posterior femur without marginal groove, shining,
