anterior legs and the antenna? are occasionally almost entirely black ; 

 the tendency, however, i,s always for the male to have these parts more 

 lightly coloured than the female. The males may easily be identified 

 by the slightly curved intermediate tibiae, which are sinuous on the 

 inner edge and sharply bideutate at the inner apical angle. In the 

 series of specimens captured by myself at different times at Claygate 

 and Ashtead, Surrey, there are all the gradations in the colour of 

 the legs and antennae. Dr. Power's examples of B. rufipes from 

 " Surbiton " were also no doubt from Claygate. The only other 

 British localities from which I possess specimens are Guildford and 

 Hastings. 



J5. vicice, Oliv., recorded as having been taken by Dr. Power at 

 Hurst and the Devil's Dyke, Brighton (whose specimens cannot now be 

 found in the Power collection at the British Museum), and by myself 

 on the chalk hills at Caterham, must be named B. Fahi'cei, G-yll., a variety 

 of B. ntomarius, Einn., from which it differs in the almost entirely 

 black legs and antennae. The two examples in my collection are both 

 females, and were captured on May 30th, 1876. The males of B. 

 ntomarius differ from those of B. rufipes in having the intermediate 

 tibipe armed Avith a sharp tooth at some distance before the apex, and 

 their inner apical angle acute. The true B. vicia? has the legs black, 

 the thorax shorter than that of B. afomarius, and the intermediate 

 tibiae of the male bidentate at the apex; it differs from B. rufipes in 

 its trapezoidal thorax. B. vicice is a more southern insect than B. 

 ntomarius, var. Fahrcei, and apparently does not occur in the north of 

 France or in Britain ; I have taken specimens of it at Vernet, in the 

 Eastern Pyrenees. 



I^he introduced Br ucJi us found by Messrs. Wilkinson and Lawson 

 at Scarborough, and freely distributed by them under the name of B. 

 pectinicornis, Linn., is B. incarnatus, Boh., recorded from Egypt, Spain, 

 and Southern France. The true B. pectinicornis, also an introduced 

 species, has, I believe, recently been found by Mr. E. A. Waterhouse 

 near Putney, quite away from houses. 



I am much indebted to M. Bedel, of Paris, for calling iny atten- 

 tion to the incorrect identification, &c., of these insects by British 

 Coleopterists, and also for examining some of my examples of the 

 above-mentioned species. 



The sexual variation of B. rufipes was observed by me years ago, 

 but not recorded.
