in B. tertiaria, but the seventh stria (from the suture) frequently runs to, or 

 very nearly to, the tip ; the extreme tip is formed precisely as in B t-r- 

 tiaria, but the side-; of the elvtra, running parallel throughout three-quar- 

 ters of their length, taper toward the apex more abruptly than ID tin- pp 

 ceding species, though with tin- same regularity. This species stands mid- 

 wav between tin- other two lien- described in the form ot' the apical third of 

 the elytra.

A single specimen, >howing the greater part of both elytra in natural 

 conjunction, must In- separated from the two preceding by its still broad. -r 

 elvtra \vitli more rapidly taperinvf apex. The elytra are slightly less than 

 three ami a half times lunger than broad, with sides parallel throughout 

 three-quarters of their length, then suddenly tapering, the extreme tip 

 shaped as in the other species, only more produced, so as to form more dis- 

 tinctly a kind of lobe, the outer margin being very slightly and roundly 

 excised just before the produced tip. The surface is perhaps even rougher 

 than in the other species, but the stria- appear to lie !.-* sinuous; the >cu 

 tellar stria is destrov.-d in both elytra of the single specimen bi-fon-m.-: the 

 outer stria terminates as in B. tertiaria, but the inner pair of the middle 

 series of stria- is here the longer, extending barelv to the tip of the outer 

 stria, while the outer pair is a little shorter; the produced tip of the elytra 

 is a little shorter than in the preceding species, but similarly roun.k-d 

 apically.
