AMERICAN COMPONENTS OF THE TENTYRIIN.-E 443 



relative lengths of the anterior tarsal joints are almost sub- 

 generic. AIa7'itinms appears to be much rarer than ovipennts, 

 which is rather abundant. The male is distinctly less obese 

 than the female and usually much smaller in size. 



Trichiotes n. gen. 



With mandibles and epistomal lobe formed as in Micromes^ 

 the present genus reproduces Trioroj^hus in general form and 

 sculpture, but differs from either in being clothed sparsely with 

 very long erect and conspicuous setiform pubescence. The 

 head is nearly as in Triorophiis, excepting the front and man- 

 dibles, the rather prominent and coarsely faceted eyes being 

 bounded above by a short and rather feeble carina ; they are 

 transversely oval and are not more than feebly impressed anteri- 

 orly by the canthus of the front. The antennag and legs are 

 rather short and stout, the tarsi notably short, the met-episterna 

 narrow, not intruding upon the epipleuras, which are narrow 

 though equally wide throughout as in Trwropkus, and the 

 elytra, similarly, have regular series of coarse punctures. The 

 form of the prothorax is almost exactly as in Triorophus^ but 

 the flanks are subevenly convex and without trace of beaded or 

 reflexed side-margin, being very obtuse in section. The single 

 species may be described as follows : — 



Form rather stout, very strongly convex, shining, clothed throughout 

 with very long erect yellowish-cinereous hairs, not concealing the 

 integuments, serial in arrangement on the elytra and arising from 

 the interstitial punctures, black, the under surface, legs and an- 

 tennas more or less paler piceo-rufous ; head evidently narrower 

 than the pi'othorax, rather wider than long, coarsely, somewhat 

 closely and, toward the sides, more or less confluently punctato- 

 rugose ; prothorax nearly one-half wider than long, parallel, with 

 the sides broadly arcuate anteriorly, becoming strongly and arcu- 

 ately narrowed in about basal half, the sides sinuate before the 

 acute and minutely prominent basal angles, the apex broadly sin- 

 uate, with the angles acute, slightly everted and prominent though 

 not produced ; surface very strongly, evenly convex, very coarsely 

 and closely but not confluently punctate ; scutellum small, trans- 

 verse, forming part of the strongly elevated basal margin of the 

 elytra as usual in this tribe; elytra strongly inflated and convex, 

 oval, about a fifth longer than wide, scarcely three times as long 

 as the prothorax and, at the middle, fully two-thirds wider, hav- 

 ing each nine regular and broadly impressed entire series of coarse.
