DESCRIPTIONS OP NEW SPECIES. 97 



propriety of placing it as a new genus, near Tarsostenus ; the 

 antennae have the last three joints slightly enlarged and more 

 approximate than in Clerus sanguineus. The last joint of the 

 labial palpi is very large and dilated ; the maxillary palpi cannot 

 be seen.

341. H. siibfasciata. Nigro-senea, pube longa argentea vestita, et 

 parce nigro-pilosa, capite confertim subtilius punctato, thorace latitudine 

 breviore, lateribus subito fortiter dilatatis, medio parce, lateribus sub- 

 tiliter densius punctato, vitta angusta dorsali laevi ; eljtris parallelis, 

 apice serrulatis singulatiin rotundatis, confertim punctatis. fascia mox 

 pone medium pilis transversim positis ; antennis palpis tibiis tarsisque 

 testaceis ; femoribus p'osticis elytris baud longioribus. Long. -21. 



Two specimens, from Nebraska, given me by Mr. Ulke. Larger 

 than the largest specimens of H. humeralis, and readily distin- 

 guished by the less coarse punctures of the elytra, and by the 

 extremely coarse silvery' pubescence, which, on the elytra, is 

 directed both longitudinally and transversely; just behind the 

 middle there is a transverse band in which all the hairs are 

 directed outwards : a similar space, though less obvious, is seen 

 at the base, extending one-third the length along the suture. 



342. H. pedalis. Elongata, nigra, supra cyanescens, pilis longis 

 albidis vestita, capite subtiliter punctulato, cum oculis tborace paulo 

 latiore, boc latitudine sublongiore, lateribus late modice dilatatis, rugu- 

 loao et parce punctato ; elytris abdomine paulo brevioribus parallelis, 

 liumeris prominulis, apice dehiscentibus, singulatim rotundatis, serratis, 

 fortiter punctatis ; antennis palpisque testaceis, pedibus anticis testaceis, 

 mediis fuscis testaceo-variegatis, posticis nigris, femoribus posticis ab- 

 domine baud longioribus. Long. *18. 



One pair, Rock Island, Illinois ; Mr. B. D. Walsh. The lateral 

 dilatation of the thorax is a little less prominent than in H. 

 pallipennis, but more distinct than in H. verticalis. The hind 

 thighs of the male extend to the tip of the abdomen, but in the 

 female only to the tip of the elytra. 



343. H. SClmsteri. Valde elongata nigra, parce albo-pilosa, capite 

 cum oculis thorace sesqui latiore, nitido fere bevi, thorace fere l?evi 

 latitudine longiore, lateribus late paulo dilatatis ; elytris grosse punctatis, 

 abdomine paulo brevioribus, parallelis, humeris late rotundatis, apice 

 paulo dehiscentibus, singulatim rotundatis serratis, laete flavo-rufis, 

 macula suturali lata a medio ad apicem extensa ornatis, abdomine
