DESCRIPTIONS OP NEW SPECIES. 



baud prolongatis, striis fortiter punctatis parum impressis, interstitiis 

 punctulis paucis sparsis iiotatis ; femoribus anticis muticis. Long. -54. 



Two specimens, from Cape San Lucas, Lower California, col- 

 lected by Mr. Xantus. The thorax is formed as in the preceding, 

 but is a little narrower and less rounded on the sides, The elytra 

 are more suddenly declivous behind, less acute, and not prolonged 

 at tip ; the front thighs are very slightly sinuate beneath, but not 

 armed with a tooth. The prosternum is armed with a small 

 prominence behind the coxa?. 



3S6. E. aspera. Nigra, capite thoraceque opacis, fortiter sat dense 

 punctatis, hoc latitudine paulo breviore, obovato modice convexo, apice 

 subemarginato, basi paulo sinuata apice baud angustiore, lateribus 

 teuuiter marginatis rotundatis, postice subsinuatis, angulis posticis 

 obtusis baud rotundatis ; elytris ovalibus, thorace duplo latioribus basi 

 emargiuatis humeris subacutis, apice valde declivibus oblique atten- 

 uatis, dorso deplanatis, lateribus subito inflexis, undique granulis recli- 

 natis nitidis breviter piliferis dense subseriatim positis, et parce trans- 

 versim rugosis ; antennis capite thoraceque vix brevioribus, extrorsum 

 paulo incrassatis ; femoribus anticis muticis. Long. -60. 



One specimen, from New Mexico, in the collection of Mr. Ulke. 

 Allied to E. granulata and humeralis, but differs by the much 

 stronger sculpture of the elytra. The outer spur of the front 

 tibiae of the male, as in those species is enlarged, as long as the 

 first three joints of the tarsi, and obtuse at tip. The under sur- 

 face is punctured,. and the prosternum is not prolonged behind. 



37. E. SUbaspera. Nigra subnitida, capite thoraceque confertim 

 subtilius punctatis, hoc latitudine breviore, apice vix emarginato, 

 angulis anticis acutis haud prominulis, lateribus tenuiter marginatis 

 valde rotundatis postice haud sinuatis, basi fere truncata apice vix 

 angustiore, angulis posticis obtusis ; elytris ovalibus, thorace sesqui 

 latioribus, dorad parum convexis, apice valde declivibus, lateribus 

 subito inflexis, undique granulis parvis subseriatim positis, versus 

 latera et apicem breviter piliferis ; femoribus anticis muticis ; antennis 

 capite thoraceque haud brevioribus, extrorsum parum incrassatis. 

 Long. -60. 



A unique specimen, from Colorado Territory, given me by 

 Dr. S. Lewis. Differs from the preceding by the finer sculpture 

 both of thorax and elytra, and by the humeri not being prominent. 

 It seems to be more nearly related to E. inculta, but the thorax 

 is more rounded on the sides, the antennas are less elongated and
