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

 very nearly to, tlie tip ; the extreme tip is formed precisely as in B. ter- 

 tiaria, but the sides of the elytra, running' parallel throughout three-quar- 

 ters of their length, taper toward the apex more abruptly than in the pre- 

 ceding species, though with the same regularity. Tliis species stands mid- 

 way between the other two here described in the form of the apical third of 

 the elytra.

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

 conjunction, must be separated from the two preceding by its still broader 

 elytra with more rapidly tapering apex. The elytra are slightly less than 

 three and a half times longer 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 stride appear to be less sinuous; the scu- 

 tellar stria is destroyed in both elytra of the single specimen before me ; the 

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

 series of striae is here the longer, extending barely 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 rounded 

 apically.
