16 PROCEEDINGS OP THE NATIONAL MUSEUM vol.80 



disk with a narrow, transverse depression in front of basal margin, 

 apical third broadly, transversely concave, and ornamented with two 

 small, round, black tubercles in front of middle; surface densely 

 clothed with long, recumbent, brownish-white pubescence, which con- 

 ceals the surface. Scutellum triangular, curvilinear, and densely 

 clothed with long, recumbent, brownish-white pubescence. 



Elytra at base distinctly wider than pronotum at middle ; humeri 

 prominent and strongly elevated ; sides nearly parallel from base to 

 near apices, then arcuately narrowed to the tips, which are each 

 bispinose, with the sutural spine distinctly shorter than the lateral 

 spine ; surface moderately convex, densely clothed with long, recum- 

 bent, whitish pubescence, which nearly conceals the surface, except 

 a broad, nearly glabrous area surrounding the eburneous spots, where 

 the surface is coarsely punctate, with a short, white hair arising from 

 each puncture; each elytron ornamented with two pairs of small, 

 oval, widely separated, eburneous spots, the outer spot of the median 

 pair slightly in advance of the inner spot. 



Body beneath rather densely clothed with long, recumbent, white 

 pubescence, not entirely concealing the surface, finely, densely punc- 

 tate, with a few coarser punctures intermixed. Middle and posterior 

 femora bispinose, with the inner spine slightly longer than the outer 

 one. 



Length, 20 mm. ; width, 5 mm. 



Type locality. — Guayama, Porto Rico. 



Type. — In American Museum of Natural History. Labeled 

 "Aguirre Centr. (Guayama) P. E., April 15, 1930, Cornell Univ. 

 Lot 795, sub. 31." 



Remarks. — Described from the type, a female. 



This species is allied to tetrastalacta White, but can be distin- 

 guished from that species by the denser and longer whitish pubescence 

 on the dorsal surface, the eburneous spots on the elytra widely 

 separated, and the outer spot of each median pair placed in advance 

 of the inner spot. 



EBURIA CUBAE, new species 



Male. — Form broadly elongate. Above and beneath uniformly 

 brownish yellow, nearly glabrous, and each elytron ornamented with 

 two pairs of small, oval, eburneous spots. 



Head transverse in front, deeply, transversely, triangularly de- 

 pressed behind the epistoma, narrowly, longitudinally grooved 

 between the antennal tubercles, which are widely separated but 

 scarcely elevated ; surface slightly uneven, densely, confluently punc- 

 tate, more or less scabrous, and sparsely clothed with short, incon- 

 spicuous, recumbent hairs; eyes deeply emarginate, separated from
