I have examined this example, which is still unique and 

 lather the worse for wear. 



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

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

 almost exactly resembles that of that 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 this 

 sj)ccimen does seem rather broader than tliat of B. luteolus. 



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

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

 1.S78. 



First leg : tibia a)ul metatarsus very black, contrasting 

 strongly with the other articles, which 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 

 rest of the leg pale brown. 



Fourth leg : j)atella 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. 



Tliis leg-pigmentation is very extraordinary, and the colour 

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

 inky black. 



With the vulva not quite typical and this curious pigmenta- 

 tion j)resent I sliou'd certainly hesitate to remove tiiis species 

 from the British list. It i.'^, however, very closely related to 

 J3. luteolus. 



Tlie specimen was found near Belfast l)y Mr. F. Workman.

Tlie examination of the ly|je of L. culta showed clearly 

 that it was a female of L. impigra.
