VII. EUSCEPES Schon., 1844. (Gr., "beautiful" + "vestiture.") 



Elongate subparallel species, having the funicle 6- jointed, the 

 first and second joints elongate, three to six short, snbglobose; 

 second ventral segment longer than either third or fourth, which 

 are subequal and together equal in length to fifth ; middle and 

 hind coxa? more widely separated than in Acallcs. One species 

 occurs in Florida. 



764 (8770). EUSCEPES POECELLUS Boh., Schn., 1844, 430. 



Elongate, subcylindrical. Brown, densely clothed with dark brown and 

 clay-yellow scales, the latter covering the basal and apical thirds cf elytra. 

 Beak of male stout, shorter than thorax, striate, finely carinate, densely 

 scaly; of female more slender, one-third longer, glabrous and shining near 

 tip. Thorax slightly longer than wide, widest at middle, sides feebly 

 rounded, sculpture hidden by scales. Elytra oblong, one-fourth wider at 

 base than thorax, humeri prominent, sides nearly parallel; less obliquely 

 narrowed and more broadly rounded behind than usual; strial punctures 

 large, round, close-set; intervals narrow, convex, each with a row of rather 

 long, slender, pale erect setae. Under surface sparsely but evenly covered 

 with large oval whitish scales. Length 2.3 2.7 mm.

 beneath decaying stems of the water hyacinth, Plaropus cras- 

 sipes Mart., next to the water's edge. Biscayne, Miami, Enter-

 (1876, 244) is a synonym. Both LeConte and Pierce include this 

 erroneously among the species with 7-jointed funicle. 



VIII. TYLODERMA Say, 1831. (Gr., "rough" + "skin.") 



Oblong or oblong-oval, usually nearly glabrous species of a 

 dark color, having the beak short and stout, the apex of the pec- 

 toral groove receiving it in repose therefore not extending so far 

 into the mesosternum and rendering the emargination of that 

 segment more shallow; eyes small, widely separated, both they
