In its very oval elytra resembles the St. Helena Bcmhiilia more than any 

 group of Europe or North America. The curA-e of the sides continues to the 

 end of the plica which forms a little angle near the basal angle of the thorax. 

 The general form is rather short and oval, the surface glossy, the elytral 

 strise scarcely impressed, and the width of the tawny border very irregular.

Approaches in form the species allied to B. decorum, but the elytra 

 narrowed in a moderate curve to the base without trace of humeral angles, 

 and the meml)ranous wings wanting. The frontal furrows are moderately 

 long ; the punctures of the thiid elytral interstice in well-de^'eloped examples 

 extend across the interstice ; the strife are scarcely at all impressed, and are 

 rendered apparent only l^y the convexity of the interstices. 



42. B. {Nota'plius) Cayambcnse, n. sp. 



Hab. Village of Cayambe (9320 feet). Two examples. 



B. Aubei (Solier) affine sed magis depressum ; Kneum, immaculatum, 

 scapo pedibus rufo-testaceis seneo-tinctis : foveis frontalibus simplicibus latis : 

 thorace antice pauUo magis quam postice angustato, angulis posticis subacutis, 

 basi utrinque fovea lata, alteraque angusta ab angulo carina separata : elytris 

 oblongis, punctato-striatis striis vix impressis, interstitiis planissimis 3'" et 

 5*° cseteris latioribus, 3'" ])unctis duobus in medio interstitio sitis.
