AMERICAN COMPONENTS OF THE TENTYRIIN^ 381 



alluded to further in more than an incidental way. Ef (tragus^ 

 for example, only extends slightly into Central America from 

 its proper habitat, which is South America.^ Hcmasodes (n. 

 gen.), is founded upon the remarkably isolated Schcenicus 

 vcstittis, of Champion. Ortkeolus (n. gen.), is represented at 

 present only by the neotropical Sc/nvnicus oculahis, of Cham- 

 pion, while Tydeolus Champ., is represented by three rather 

 rare Mexican species, apparently having a good deal the facies 

 of Conceals and probably at least subapterous. 



Polemiotus n. gen. 



In its strong supra-orbital ridges, prominent and somewhat 

 everted lateral lobes of the front, anteriorly subtruncate pro- 

 thorax, with rounded angles and elongate body, with widely 

 exposed and rounded humeri, this genus is one of the more dis- 

 tinct of the tribe. The eyes are large and transversely oval, 

 feebly emarginate anteriorly by the rather thick canthus, some- 

 what prominent and only relatively coarsely faceted, the supra- 

 orbital ridges bounded internally by deep coarse excavations, 

 somewhat as in Meto^oloba, where the eyes are almost similarly 

 coarsely faceted but less convex. The anterior tibiae are slender 



'The following Central American Epitragus has been hitherto uncharac- 

 terized : — 



Elongately fusiform, convex, polished, pale red-brown, the upper surface with 

 scattered recumbent yellow hairs, closer toward the eyes and sides of the pro- 

 notum and tending to form denser clusters on the elytra ; head rather coarsely 

 punctured, the punctures separated by about twice their diameters medially ; 

 prothorax a third wider than long, the sides evenly and moderately arcuate, 

 slightly more so at tip, becoming subparallel in nearly basal half, the basal 

 angles right, not rounded ; apex more than three-fourths as wide as the base, 

 the punctures close and small laterally, large and sparse medially, without 

 well defined impunctate line except in basal half, the surface at each side 

 with a large elongate-suboval impression basally at lateral fourth and a trans- 

 verse feebler impression before the basal lobe, separated from the lateral 

 impressions by a very feeble convexity; elytra three times as long as the 

 prothorax, at base a fifth or sixth wider, the sides broadly arcuate, the tip 

 acute, the hvimeri rounded ; surface with wholly unimpressed series of rather 

 coarse, widely spaced punctures, the intervals with smaller confused punc- 

 tures, sparse with aggregated denser patches, the entire surface rugose. 



Length ii.o mm. ; width 4.15 mm. Honduras * rigens n. sp. 



I formerly regarded this as 5a//eV Champ., but it differs greatly in its unim- 

 pressed elytral series and is undoubtedly specifically different.
