ULOSOMINUS.—PERIERES. 485 
punctate-striate, the punctures subquadrate, the interstices narrow, punctulate, 3, 5, and 7 slightly raised. 
Beneath closely, finely punctate. Legs short and comparately stout, the femora unarmed. 
Length 24, breadth 1 millim. (3?) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One specimen. A very small, oblong, depressed form, with very long intermixed 
erect setee on the apical declivity of the elytra and on the anterior part of the prothorax, 
the short sete arranged in a close series on the alternate elytral interstices 3, 5, and 7. 
The metathoracic episterna are very narrowly exposed behind. 
6. Ulosominus angustatus, sp. n. 
Oblong-ovate, narrow, shining, piceous or rufo-piceous, the rostrum and antenne ferruginous; clothed with 
brownish or ochreous scales, intermixed with long, erect, clubbed sete. Head and base of the rostrum 
closely punctate, the apical half of the latter punctate at the sides and smooth down the middle, the eyes 
small, Prothorax broader than long, constricted and narrowed in front, densely punctate. Scutellum 
invisible. Elytra rather convex, a little wider than the prothorax, subparallel in their basal half; 
coarsely punctate-striate, the punctures subquadrate, the interstices narrow and rather convex, 1, 3, 5, 
and 7 setigerous. Legs slender, the femora unarmed. 
Length 12-21, breadth 4-1 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Two specimens. Smaller and more convex than U. triseriatus, the elytra less parallel, 
the sete scattered and equal in length, the legs comparatively slender. 
PERIERES, gen. nov. 
Rostrum short, curved, triangularly dilated at the base, the antennz inserted behind the middle, the funiculus 
7-jointed, joint 2 nearly as long as 1, 3-7 transverse, the club ovate and with distinct sutures; eyes large, 
rounded as seen from above, rather narrowly separated ; prothorax transverse, subconical, bisinuate at 
the base, the ocular lobes partially covering the eyes; elytra with ten rows of punctures, gibbous, the 
sides in front forming an almost continuous outline with those of the prothorax, the suture rounded 
on each side of the depressed, squamigerous scutellum ; mesosternum arcuate-emarginate in front; 
metasternum extremely short, the very narrow episterna just visible; ventral segments 2-4 very short, 
equal in length, the sutures straight ; femora hollowed at the apex beneath, unarmed ; tibia feebly 
unguiculate at the outer apical angle; tarsi with Joint 3 broadly bilobed, the claws minute and 
approximate ; body convex, pyriform, apterous. 
The single species referred to this genus cannot be included in Avcalles, even in the 
widest sense, differing as it does in the general shape of the body, &c. 
1. Perieres gibbipennis, sp.n. (Tab. XXIII. figg. 27, 27 a.) 
Pyriform, convex, shining, black, the elytra piceous, the antennz and the tips of the tarsi ferruginous ; thickly 
clothed with coarse brown scales intermixed with a few very short, erect, darker sete, the scales covering 
the scutellum ochreous, the vestiture of the under surface paler. Head and rostrum closely, very finely 
punctate, the latter squamose at the base only. Prothorax densely punctate. Elytra coarsely seriate- 
punctate, the punctures oblong in shape, the interstices broad, almost flat, extremely minutely punctate. 
Beneath closely punctate. Legs rather long, moderately stout. 
Length 4, breadth 22 millim.
