punctate, densely clothed with long, recumbent, gray pubescence,

 and abruptly declivous in front. Legs rather densely clothed with 

 long, recumbent and erect, grayish hairs intermixed; femora rather 

 robust, strongly expanded at middle, but not spinose at apices. 



Length, 16 mm. ; width, 4 mm.

j^/^je.— U.S.N.M. No. 43715. Collected in 1920, by G. N. Wolcott.

This species can be distinguished from the other described species 

 of Elaphidion found in the West Indies by the following combina- 

 tion of characters: Third and fourth antennal joints unispinose, 

 prosternal process abruptly declivous at apex, elytra broadly rounded 

 at apices and not spinose, and the femora not spinose at apices. 



ELAPHIDION CAYAMAE, new species 



Female. — Narrowly elongate, subcylindrical, strongly convex 

 above, and similar in form to villosum, Fabricius. Above and be- 

 neath uniformly dark reddish brown, feebly shining, and irregularly 

 clothed with recumbent, gray pubescence. 



Head sparsely, coarsely, irregularly punctate, longitudinally ru- 

 gose, sparsely clothed with long, recumbent, yellowish-white pu- 

 bescence, with a few long, erect hairs intermixed, front distinctly 

 wider than long, feebly concave between the antennal tubercles, 

 which are widely separated, and slightly elevated; eyes deeply 

 emarginate, separated from each other on the top by twice the width 

 of the upper lobe. Antenna not quite so long as the body, basal 

 joints coarsely, irregularly punctate, sparsely clothed with long, 

 recumbent, white pubescence, with a few long, erect hairs on the 

 underside of the joints, apical joints finely, densely punctate, and 

 densely clothed with short, recumbent, white pubescence, joints 3 

 to 7 unispinose at apices, the spines on joints 3 and 4 very long; 

 first joint robust, rather strongly clavate, and slightly longer than 

 the third joint; fourth joint about one-third as long as the third, 

 following joints variable in length; eleventh joint nearly twice as 

 long as the tenth, and slightly flattened. 



Pronotum as wide as long, and about equal in width at base and 

 apex ; sides rather strongly, arcuately rounded ; disk strongly convex, 

 even, and ornamented with four inconspicuous, glabrous spots, two
