242 HETEROMERA. 
tively shorter legs and antenne, the elytra widened behind (the general form in conse- 
quence being obovate), &c.; the upper surface is similarly clothed with short decumbent 
hair, amongst which a few longer hairs are here and there to be seen. 
8. Paratenetus crenulatus. 
Moderately convex, reddish-brown, slightly stained with piceous, clothed with rather long decumbent hair. 
Head coarsely and subconfluently punctured, transversely impressed in front ; antenne ferruginous, the 
club piceous, moderately large, and with the two lower joints transverse ; prothorax broader than long, 
widest about the middle, the sides slightly rounded, and about equally narrowed at the base and apex, 
the lateral margins rather coarsely crenulate, the anterior angles obtuse, the posterior angles acute, the 
surface punctured like the head; elytra widest behind the middle, the surface with numerous shallow 
transverse rather coarse punctures, which towards the sides are arranged in more or less interrupted 
longitudinal rows, the sutural region smoother, the interspaces towards the sides irregularly wrinkled ; 
legs more or less ferruginous.

Hab. Pawama, Bugaba, Volcan de Chiriqui (Champion). 
Two female examples. P. crenulatus is not very closely allied to any other species 
here described ; it will be known by the irregular rows of shallow punctures on the 
sides of the elytra and the coarsely and confluently punctured thorax. ‘The elytra are 
much more closely punctured and wrinkled in the specimen from the Volcan de 
Chiriqui. 
9. Paratenetus brevipennis. 
Moderately convex, reddish-brown, stained with piceous, clothed with long erect hair. Head coarsely and 
confluently punctured, transversely impressed in front; antenne rather long, with a moderately stout, 
loosely articulated 3-jointed club, ferruginous, the club (except at the extreme apex) piceous ; prothorax 
transverse, feebly rounded at the sides, widest in the middle, about equally narrowed at the base and 
apex, the angles acute, the sides crenulate, the surface punctured. like the head; elytra comparatively 
broad and short, much broader than the prothorax, slightly rounded at the sides, with irregular interrupted 
rows of very coarse punctures, the sutural region more finely and sparingly punctured; legs rather 
stout, reddish-testaceous, the femora and tibiz stained with piceous ; tibie slightly curved, the anterior 
pair armed on the inner side a little before the middle with a sharp tooth, and the inner apical angles 
of the intermediate pair distinctly (those of the posterior pair slightly) produced, in the male.

One example. 
10. Paratenetus tuberculatus, (Tab. X. fig. 25, ¢.) 
Convex, reddish-brown or piceous, rather thickly clothed with long cinereous erect hair. Head coarsely and closely 
punctured, transversely impressed in front ; antenne similar in both sexes, the club stout, coarsely punc- 
tured, and with the two lower joints broader than long, more or less piceous, the basal joints (and some- 
times the extreme apex of the club) ferruginous; eyes comparatively large, coarsely faceted ; prothorax 
broader than long, widest about the middle, the sides slightly rounded and narrowed anteriorly, 
the lateral margins prominent and coarsely crenulated, the anterior angles obtuse, the posterior angles 
acute, the base transversely grooved within in the middle, the dise with an irregular curved or sinuous 
depression on each side, the surface very coarsely, closely, and irregularly punctured, the punctures con- 
fluent at the sides; elytra very convex, slightly rounded at the sides, widest beyond the middle, the apex
