52 PROCEEDINGS OF THE NATIONAL. MUSEUM vol. 80 



Pronotum as wide as long, and subequal in width at base and 

 apex; sides feebly, arcuately rounded at middle, more strongly 

 rounded toward apex, and strongly, narrowly constricted at base; 

 anterior margin broadly, arcuately rounded; disk rather strongly 

 flattened; surface glabrous, finely, longitudinally rugose, the rugae 

 narrow, strongly elevated, more or less irregular, and close together. 

 Scutellum narrowly transverse, emarginate at apex, and glabrous. 



Elytra three times as long as pronotum, and at base subequal in 

 width to the pronotum at middle; humeri rather strongly elevated; 

 sides nearly parallel from base to apical fifth, then arcuately nar- 

 rowed to the tips, which are separately, narrowly rounded; disk 

 feebly flattened; surface glabrous, coarsely, densely, uniformly 

 punctate. 



Abdomen beneath glabrous, rather densely, coarsely, but not 

 deeply, punctate; last segment broadly rounded at apex. Proster- 

 num strongly convex, nearly glabrous, rather densely, coarsely, but 

 not deeply, punctate; prosternal process very narrow between the 

 coxal cavities, and arcuately declivous posteriorly. Legs rather 

 short, sparsely clothed with short, recumbent, inconspicuous pubes- 

 cence; femora gradually, strongly clavate, petiolate at bases, un- 

 armed at apices; tibiae robust, expanded toward apices, but not 

 longitudinally carinate. 



Length, 4.75 mm.; width, 1.4 mm. 



Ty^pe locality. — Cayamas, Cuba. 



Type. — ^U.S.N.M. No. 43732. A unique example (sex not deter- 

 mined), collected January 19, by E. A. Schwarz. 



Remarks. — Described from the type. 



This little species differs from all the other described species of 

 this genus found in the West Indies in having the upper surface 

 glabtous, and the pronotum finely, densely, longitudinally rugose. 

 It does not quite agree generically with f.ava Fabricius, the type of 

 the genus, but it is placed temporarily in this genus until more 

 material is available for study. 



MEROSTENUS ASPERATUS, new species 



Male. — Narrow, elongate, subcylindrical, and similar in form to 

 attenuatus Chevrolat. Above and beneath opaque, uniformly pale 

 reddish brown, the antennae and legs feebly paler. 



Head densely, minutely alutaceous, glabrous, front wider than long, 

 rather deeply, narrowly depressed behind the epistoma and along 

 inner margin of eyes, with a vague, narrow, longitudinal, median 

 groove, feebly, broadly concave between the antennal tubercles, which 

 are slightly elevated; surface broadly, transversely concave on ver- 

 tex; eyes large, strongly convex, moderately emarginate, and widely
