silken cocoon, suspended in the spider's web, change to the pupa 

 state. From the pupro (six in number) there emergod, not 

 many days afterwards, six small hymenopterous insects. The 

 spiders shrivelled up and died immediately after thoy became 

 freed from their parasitic enemies. Many previous attempts to 

 rear the perfect insect had failed. 



Dr. Capron, of Shore, near Guildford (to whom I forwarded 

 examples of tho parasite), tells me that he bolieves it to be

GENUS EEO, C. L. Koch. 



Eeo tubekculata, De Gecr (p. 235). 



By an oversight Ero atomwia, C. L. Koch, is included (I.e.) as 

 a synonym of this specios ; the synonymic reference was intended 

 to have been made to Ero tuberculata, C. L. Koch, Die Arachn, vol. 

 xii., p. 107, pi. 420, fig. 1,034. Ero atomaria, C. L. Koch, has not 

 yet been found in Great Britain. 



GENUS ULOBOEUS, Walck 



Ulobouus walckenaerius (p. 285), pi. vi., fig. 2. 



A fine and well marked example of the adult malo of this 

 rare t spider, sent to me by the "Rev. C. W. Penny from near 

 Wokingham several years ago (but mislaid until very lately), 

 induces me to add now a short note upon it. It diffors from the 

 female in the longer and stronger legs of the first pair, which 

 have a longitudinal row of short, strong spines (articulated to 

 minute tubercular eminences) along the inner side of the tibia). 

 The abdomen is longer, narrower, and less convex above than 

 in the female. The three longitudinal dark-brown stripes aro 

 more distinctly traceable on tho upper side of the abdomen, but 

 the central stripe has its hinder part broken by two or three short 

 angular bars or chevrons, and the lateral ones are also strongly 

 dentated on the inner side of the posterior half. This gives the 

 upper side of the abdomen quite a different appearance from
