plane transverse intervals, and the striae, which are very narrow, 

 have a series of very small granules running nearly parallel with 

 those on the costae ; the latter are almost always of equal height, 

 but I have seen two examples in which the two dorsal ones Avere a 

 little higher than the others ; the sutural costa is not granulose ; 

 basal joint of posterior tarsi slightly shorter than the apical 

 spur.

Eesembles closely B. atramcntarius, but the elytra are a little 

 less parallel, the humeral angles are not so sharp, and the elytra are 

 & little less elongate, the dorsal costse are also tectiform, but the 

 first four dorsal ones are more distinctly carinate at tip, and 

 the sharp line is hardly punctulate, even the lateral costae are not 

 ■deeply punctate, the striae are punctate, not granulose, and the 

 walls of the tectiform costae are manifestly punctate ; the basal joint 

 of the posterior tibiae is a little shorter than the apical spur. In my 

 South African examples (2) the sides of the costae are not quite as 

 deeply punctate as in the European ones.

Ehyssemus promontorii, n. spec. 



Head and prothorax fuscous black, elytra dark ferruginous or 

 fuscous brown ; the shape and the sculpture of the head and 

 prothorax are similar to those of the preceding species, but the 

 sculpture of the costae on the elytra is different, these costae are 

 tectiform, but they have on each side a slanting, deep, foveate 

 puncture impinging on the apex of the costa and making it appear 

 granose, moreover, these punctures in the basal part, and also on the 

 sides are somewhat deeper in proportion near the top of the sides, 

 and the costa seems to be more or less duplicate, the striae are very 

 narrow, and the basal joint of the posterior tarsi is slightly shorter 

 than the apical spur.
