14 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 80 



Type. — In American Museum of Natural History. Collected on 

 the San Carlos Estate, at light, April 24, 1914, by C. T. Kamsden. 



Remarks. — Described from the type, a female. 



This species resembles tetrastalacta White, but it can be distin- 

 guished from that species by its more cylindrical form and the dense 

 white pubescence, which entirely conceals the surface. 



EBURIA RAMSDENI, new species 



Female. — Form broadly elongate. Above and beneath brownish 

 black, but the color is concealed by the dense brownish-yellow pu- 

 bescence (except a glabrous area around the eburneous spots), which 

 gives it a pale brownish tinge, and each elytron ornamented with 

 two pairs of small, rounded, eburneous spots. 



Head transverse in front, deeply, transversely grooved behind the 

 epistoma, narrowly, longitudinally grooved between the antennal 

 tubercles, which are strongly elevated and widely separated; surface 

 somewhat uneven, coarsely, irregularly punctate, densely, irregularly 

 clothed with long, recumbent, brownish-yellow pubescence; eyes 

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

 the width of the upper lobe. Antennae broken, basal joint scabrous, 

 following joints finely, densely punctured, and rather densely clothed 

 with short, recumbent, white pubescence, with numerous long, erect 

 hairs on the underside of the joints; first joint robust, flattened on 

 underside, slightly clavate, and one-half as long as the third joint, 

 which is subequal in length to the fourth. 



Pronotum slightly wider than long, and about equal in width at 

 base and apex ; sides arcuately rounded, strongly constricted at base, 

 broadly swollen at apical angles, and armed on each side with a long, 

 acute spine; disk uneven, feebly, transversely depressed along base, 

 broadly flattened along apical margin, with a deep depression on 

 each side near apical angle, and ornamented with two round, acute, 

 black tubercles in front of middle ; surface densely clothed with long, 

 recumbent, brownish-yellow pubescence, which conceals the surface, 

 except a very narrow, longitudinal, median line. Scutellum triangu- 

 lar, culvilinear, and densely clothed with long, recumbent, whitish 

 pubescence. 



Elytra at base about equal in width to pronotum at middle ; humeri 

 prominent and strongly elevated; sides nearly parallel from base 

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

 bispinose, with the sutural spine slightly shorter than the lateral 

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

 cumbent, brownish-yellow pubescence (slightly denser and paler 

 alonar sutural jnar£»-ins), nearly concealing the surface, except for a
