DESCRIPTIONS OF NEW SPECIES. 157 



Cape San Lucas ; collected by Mr. Xantus. A very distinct 

 species, not needing further description to enable it to be re- 

 cognized. 



EPICAUTA REDT. 



45T. E. pedalis. Nigra minus dense cinereo-pubescens, capite punc- 

 tato, thorace capite angustiore, latitudine longiore. sat dense punctate, 

 canaliculate ; elytris confertim subtilius punctatis ; antennis nigris 

 articulo 3io sequentibus duobus vix breviore, 2ndo brevi ; pedibus fer- 

 rugineis, artubus fuscis. Long. '38. 



Three males collected at Cape San Lucas, Lower California, 

 by Mr. Xantus. The 3d, 4th, and 5th joints of the antennas are 

 thicker than the outer ones, which diminish gradually in width, 

 as in the male of E. morio. 



458. E. con volvul 5. Atra opaca, confertissime punctata, breviter 

 pubescens, capite sat dense punctate, pone oculos laete rufo, et subtiliter 

 canaliculate ; tliorace capite angustiore, latitudine sesqui longiore, linea 

 dorsali tenui impressa ; elytris elongatis, thorace sesqui latioribus ; an- 

 tennis filiformibus, articulo 3io prsecedente plus duplo, sequente autem 

 sesqui longiore. Long. -30 -48. 



Mas capite opaco, subtiliter granulate, punctis hand profundis. 



Femina capite nitido, profunde baud dense punctate. 



Variat thorace dense cinereo-pubescente, elytris vel cinereo-pubescentibtis 



vel atris sutura margine vittaque abbreviata cinereo-pubescentibus ; 



capite nonnunquam toto nigro.

Pennsylvania to Texas. The difference in sculpture of the 

 head might readily cause the two sexes to be regarded as different 

 species. It differs essentially from E. pennsylvanica by the head 

 being less densely punctured than the thorax, and by both being 

 more strongly punqtured than the elytra. 



459. E. pardalis. Nigra, cinereo-pubescens, maculis rotundatis 

 glabris nitidis Isevibus confluentibus adspersa, interstitiis angustis 

 punctatis, lineis irregularibus undatis prsecipue transversis formanti- 

 bus ; capite thoraceque obsolete canaliculatis. Long. -40 -53. 



New Mexico and Arizona; Greneral Pope and Dr. Irwin, 

 TT. S. A. This form is allied to E. maculata, but differs by the 

 denuded spots being much larger and so confluent as to leave a

 by the naked surface being smoother and less opaque on the 

 elytra, and really polished on the head and thorax ; by the head
