ON NEW AND RARE BRITISH ARACHNID A. 113 



Agroeca diversa, sp.n. Figs. 1, 2, 3. 



Two adult females of an Agroeca, closely allied to 

 A. gracilipes, Blackw., were found by A. E. LI. P.-C. 

 on Blox worth Heath at the end of the summer of 1912. 

 In size, general structure, and character these are very 

 like A. gracilipes, but the striking dissimilarity in colour 

 and markings, as well as some small structural differences, 

 lead me to believe them to be of a different species.

 fig. I., and Vol. XXVI., p. 45. 

 An adult male of this interesting species was taken on 

 the lawn railings at Bloxworth Rectory on the 5th of 

 July, 1912, by the Rev. R. J. Pickard-Cambridge ; and 

 I found one of the same sex among some hitherto over- 

 looked spiders taken many years ago by myself at 

 Bloxworth.

A female adult was taken among herbage in Bere Wood 



by A. E. LI. P.-C. on the 17th of October, 1912. This is 



the first instance known to me of the occurrence of this 



species in any other situation than in old buildings and 



unused rooms.
