 Salvaza, May). 



I liave seen only a single specimen, presented to the 

 British Museum by its discoverer. 



In its markings B. longicornis is not unlike B. cardoni, 

 Gorh., but the orange-coloured fascioe are more extensive, 

 only slightly interrupted at the suture (the posterior one 

 scarcely at all), and almost connected together by the two 

 converging finger-like processes emitted by each. The pro- 

 thorax is much broader than it is represented in the figure 

 of that species and the whole outline is much more circular. 

 The puncturation of the upper surface is very closely and 

 evenly distributed and that of the elytra very deep and 

 strong, especially upon their median part. The antennso 

 are very slender and their three terminal joints form about 

 one-third of the total length.
