ON NEW AND RARE ARACHNIDS. 37 



Agroeca celans, Bl. 



An adult male was found by W. A. P.-C. on 

 Bloxworth Heath in August, 1910. The only previous 

 occurrences of this species here were of two or three 

 females taken by myself many years ago. It appears to 

 occur more frequently in North Wales (where my son 

 W. A. P.-C. met with adult females of it in September, 

 1910), and in the North of England.

The genus Corinna forms a portion of a large group of 

 spiders near to Chtbiona, Latr., and, like that genus, 

 included by M. Simon in his great work (I.e. supra) in the 

 Family Clubionidce ; it seems, however, to me to belong, 

 with Clubiona, more properly to the Drassidce, in near 

 connection with which Clubiona has always been pre- 

 viously placed. I cannot say that I have given this 

 systematic re-arrangement the study and attention it 

 requires and is due to it, and which, in connection with 

 M. Simon's systematic arrangement generally, will 

 very probably become universally established.

Two adult males of this fine and striking looking 

 species have been sent to me in 1909 and 1910 from the 

 Royal Gardens at Kew, by Mr. A. W. Hill. They were 

 found there in the " Propagating Pits," and are no doubt 

 of foreign importation. I have recorded and described 

 them here (see postea p. 50) not from any idea of their 

 being " British," in the ordinary sense of the word, but 

 simply as likely perhaps to induce other persons, who 

 have similar plant houses under their charge, to capture 

 and get identified exotic spiders that may thus come 

 under their notice.
