34 PROCEEDINGS OP THE NATIONAL MUSEUM vol.80 



eyes deeply emarginate, separated from each other on the top by 

 nearly four times the width of the upper lobe. Antenna about as 

 long as the body, sparsely punctate, sparsely clothed with short, 

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

 of the basal joints; joints 3 to 6 strongly unispinose at apices; first 

 joint robust, strongly clavate, slightly longer than the fourth joint, 

 which is two-thirds as long as the third; eleventh joint subequal in 

 length to the tenth. 



Pronotum distinctly longer than wide, subcylindrical, and equal 

 in width at base and apex ; disk strongly convex, even ; sides nearly 

 parallel, at most only vaguely rounded; surface coarsely, vaguely 

 punctate, sparsely clothed along base with long, recumbent, incon- 

 spicuous hairs, and ornamented with dense, white pubescent spots 

 as follows : A small spot in front of scutellum, a small, round spot on 

 each side near apical margin, and a transverse, irregular spot at the 

 lateral margins near middle. Scutellum broadly triangular, cur- 

 vilinear, and densely clothed with long, recumbent, white pubescence. 



Elytra nearly four times as long as pronotum, and at base dis- 

 tinctly wider than pronotum at middle; sides parallel from base 

 to near the tips, which are separatelj^, broadly truncate, bispinose, 

 the lateral spine long and acute, but the sutural one scarcely de- 

 veloped; surface sparsely, coarsely, irregularly punctate, the punc- 

 tures becoming obsolete toward apices, clothed with a few long, erect 

 hairs, and each elytron ornamented with dense, white pubescent 

 spots as follows: An elongate spot a short distance behind base, 

 a rather broad, irregular, transverse fascia in front of middle, not 

 extending to the sutural margin, and a broad, irregular, transverse 

 spot at apical fourth. 



Abdomen beneath feebly, sparsely punctate, very sparsely clothed 

 with long, erect, whitish hairs, and ornamented with a dense, whitish 

 pubescent spot at the sides of each segment, except the last visible 

 sternite, which is broadly rounded at apex. Prosternum feebly, 

 sparsely punctate, smooth along anterior margin, and sparsely 

 clothed with inconspicuous, semierect hairs ; prosternal process very 

 narrow, strongly expanded behind the coxal cavities, and arcuately 

 declivous posteriorly. Mesosternum broad, even between the coxal 

 cavities, and rather abruptly declivous in front. Legs clothed with 

 a few long, erect hairs ; femora strongly clavate, middle and posterior 

 pairs subspinose at the tips. 



Female. — Differs from the male in having the antennae shorter 

 than the body, and the prosternum more densely pubescent. 



Length, 8-11 mm. ; width, 1.8-2 mm. 



Type locality. — Coamo Springs, Porto Rico. 



Other locality. — Yauco, Porto Rico.
