NOTES ON SPIDERS 45! 



occupying nearly the whole of the posterior slope. There is a 

 wide opening in tlie liinder wall of this cavity, from which a 

 band narrowed in tlie middle stretches across to the opposite 

 boundary. On either side of this band the surface of the 

 cavity is very dark brown, and the wrinkled rim is of the 

 same colour throusfhout its length. 



Postscript. — Types of Hilaira pervicax have been care- 

 fully compared with the type of Erigone consimilis, Cb., in the 

 British Museum, and Mr. Pickard-Cambridge is satisfied that 

 they are not identical. Several examples of both sexes of the 

 spider recorded above as Microneta cmita having been sub- 

 mitted to him, he is of opinion that they are Microneta 

 passiva, Cb. This is the first definite recognition of the 

 female, and the present is the first record of the species for 

 Northumberland.
