1. B. RUIDA. — Elongated; elytra rugose. 

 Inhabits Mexico. 



Body black, punctured : thorax somewhat longer than broad, 

 punctures confluent each side and behind ; a transverse, sub- 

 basal, indented band, obsolete in the middle; lateral margin 

 rounded, the marginal, hardly elevated line being so low on the 

 side as not to be visible from above : elytra convex, covered in 

 every part with irregular rugosities. 



Length less than one inch. 



[These species all belong to E/eodes. — Leg.] 



2. B. IMPOLITA. — Opaque; thoracic basal angles slightly ex- 

 curved ; elytra simple. 



Inhabits Mexico. 



Body black, nearly opaque, very minutely punctured : head, 

 transverse line between the antennas, obsolete : thorax rather 

 wider than long, greatest width a little before the middle ; lateral 

 edge a slightly elevated line, abruptly a little excurved at the 

 posterior angle, exhibiting [184] in that part a very small, acute, 

 lateral projection : elytra smooth to the eye, but on close insjjec- 

 tion minutely and irregularly rugose and punctured ; lateral 

 margin rounded. 



Length over three-fifths of an inch. 



Much like B. aequalis, but distinguishable by its almost total 

 want of polish, the minute prominence of its posterior angle, and 

 the microscopic roughness of its elytra. 



3. B. MAURA. — Elytra with impunctured, obtuse strias. 

 Inhabits Mexico. 



Body black: head punctured, an impressed line between the 

 antennae : thorax with hardly discernible punctures ; wider than 

 long; posterior angles not rounded; lateral edge a vertically ele- 

 vated line, not in the slightest degree curved outwards near the 

 posterior angle : elytra somewhat depressed, obtusely striated or 

 grooved, the grooves impunctured, but viewed in a particular 

 direction they appear obsoletely rugose; interstitial lines convex; 

 lateral margin rounded and evidently irregularly punctured ; epi- 

 pleura impunctured ; feet punctured. 



Length more than three-fifths of an inch.
