AND EASTERN NEW MEXICO. 3 



tured at base. A very similar nondescript species from New Jersey was kindly 

 given me by Mr. Guex ; it differs chiefly by the thorax being broader, with the 

 sides less rounded and less narrowed anteriorly. I have named it H. viduus. 



H. desertUS, oblongus, piceus nitidus, tliorace latitudine breviore, lateribus rotundatis vix ex- 

 planatis, antice posticeque subangustato, angulis posticis subobtusis, subrotundatis, ad basin 

 utrinque punctulato et foveato, elytris ad apicem obtuse rotundatis, striis bene imprcssis, 2nda 

 unipuuctata ; antennis palpis pedibusque ferrugiuois. Long. 'S. 



One immature female: Mr. Fendler. Quite different from any other species 

 known to me, although having somewhat the form of H. meyaceplialus Lee. 



H. Stupidus, oblongus subovalis, convexns, ater, tborace latitudine plus sesqui breviore, lateribus 

 tenuiter marginatis antice rotundatis, postice subrectis fere parallelis, angulis posticis rectis vix 

 rotundatis, fovea basali utrinque hand profunda, basi tota punctulata, elytris (feminoe subopacis) 

 striis impunctatis, interstitiis vix couvexis, apice sinuatis, antennis pedibusque oljscure ferrugineis. 

 Long. -46. 



One specimen from rbute to Fort Bridgcr : Mr. Drexlcr. More convex than H. 

 erytlirojnis, with the sides of the thorax not flattened, and the posterior angles less 

 obtuse. From these differences in form, this species has somewhat the appearance 

 of H. funestus Lee, which however has black feet, and is otherwise quite different.

Platte River Valley, near Chimney Eock. Very different from all other species 

 yet known, by the striae of the elytra being indicated only by rows of punctures, 

 which are less obvious towards the apex and sides. 



]VO]TIARETIJS Lec. 



iV. cavicollis, reneo-purpureus, nitidus, thorace obovato, postice valde angustato, sulco dorsali 

 profundo, antice disperse punctato, jiostice latius concave, profuude impresso et punctate, elytris 

 striis utrinque 12 fortiter crenatis. Long. '45. 



One specimen. Fort Riley : Mr. John Xantus. Resembles N. fissicoUis and N. 

 hilohns (Ci/cJirus hilohus Say), but differs from both by the anterior half of the 

 thorax being covered with scattered punctures, and the posterior half being broadly 

 concave ; as in those species the posterior angles are obtuse. 



CAl-OSOWIA Fabr. 



C. luxatllin, nigrum subnitidum, capite subtilius punctato-rugoso, thorace capite sesqui latiore, 

 latitudine fere triplo breviore, lateribus valde rotundatis, postice angustiore coufertim punctato- 

 rugoso, basi late rotundatim emarginato, utrinque vage impresso, elytris rotundnto-ovatis, thorace 

 latioribus, striis tenuibus rugisque transversis imbricatim insculpti,s, versus apicem confuce rugosis.
