I have examined this example, which is still unique and 

 rather tlie worse for wear. 



In size, general facies, and ocular relations it is indistin- 

 guishable from the female of B. hUeolus, Bl. The vulva 

 almost exactly resembles that of tiiat species ; if any diffe- 

 rences are present, they are so slight as to render necessary 

 a series of examples in order to guard against variation 

 within the species. As a matter of fact, the vulva of tliis 

 specimen does seem rather broader than that of B. luteolus. 



The pigmentation of the legs is, iiowever, very striking, 

 and lias faded very little, although the example was taken in 

 18 7y. 



First leg: tibia and metatarsus very black, contrasting 

 strongly with tiie other articles, whicii are very pale brown. 



Second leg : distal two-thirds of tibia and proximal half 

 of metatarsus very black ; the rest of the leg pale brown. 



Third leg : distal two-tifths of metatarsus very black; the 

 re.st of the leg pale brown. 



Fourth leg : patella and tibia deep black, proximal half of 

 metatarsus brown ; the rest of the limb pale brown. 



Abdomen at present quite devoid of markings. 



In no case are two legs of the same pair present. 



This leg-pigmentation is very extraordinary, and the colour 

 remains, after thirty-seven years' immeision in spirit, deep 

 inky black. 



With the vulva not quite typical and this curious pigmenta- 

 tion present I should certainly hesitate to remove this species 

 from the British list. It is, however, very closely related to 

 J3. luteolus. 



Tlie specimen was found near Belfast by Mr. F. Workman.

The examination of the type of L. culta showed clearly 

 that it was a female of L. iinpiffra.
