NEW BRITISH SPECIES, ETC., IN 1863. 35 



being deeper near the suture, and evanescent as they reach 

 the sides and apex, but in the lower third of the elytra the 

 fifth stria, when almost becoming obsolete, very abruptly 

 merges into a deep oblique furrow, with a ridge on the outer 

 side, which at its commencement is slightly rounded in- 

 wards, and is continued until it joins the margin just before 

 the apex ; the margins are reflexed, and impressed in a 

 somewhat similar manner, the impressions getting fainter, 

 and becoming converted into irregular punctuation as they 

 approach the shoulders. 



The second joint of the maxillary palpi (as mentioned by 

 Mr. Bold) is very large, but a compound microscope is 

 required to define the terminal subulated joint, on account of 

 its minute proportions. 



The position of the species is at the very head of the genus, 

 it being most nearly allied to B. scutellare and B. bistria- 

 tum, of both whereof it must take precedence. 



Single examples appear from Schaum's work (loc. cit.) to 

 have been taken (mostly on the wing) at Halle, Magdeburg, 

 Baden, Steiermark, and in the Tyrol. It seems to extend 

 from the South of Europe, Crimea, Caucasus, Algiers and 

 Syria, as far northwards as St. Petersburg, but is always 

 very rare.
