132 XEW AN'D RARE BRITISH SPIDERS. 



GENUS HILAIRA (Sim.) 



Ililaira uncata Cambr. (sub. Neriene), "Spid. Dors.," p. 433, 

 and "Proc."D. N. H. and A. Field Club, vol iv., p. 151. 



On several occasions since the " Spiders of Dorset " was 

 published I have found both sexes of this spider in a swamp in 

 Morden Park ; and in September, 1888, it again occurred there 

 freely. The genus constituted for this and the next species, II. 

 excisa (Cambr.), appears to be a good one. 



Ililaira excisa Cambr. (sub. Neriene), "Spid. Dors.," p. 487, 

 and "Proc." Dors. N. H. and A. Field Club, vol. iv., p. 149. 



This spider also occurred abundantly in the Morden Park swamp 

 along with If. uncata (Cambr.) in September, 1888. 



GEN : WALCKENAERA (Bl.) 



Walckeniiera trifrons Cambr., "Spid. Dors.," p. 166. 



This spider had not been met with in Dorsetshire since 1862 until 

 the spring of 1888, when numerous examples of both sexes were found 

 among grass, &c., in a bog at Bloxworth by F. 0. P. Cambridge.

Two adult males were found by sweeping among rushes and 

 other herbage on Bloxworth Heath in May, 1888, and another in 

 the Morden Park swamp at the beginning of October in the same 

 year by F. O. P. Cambridge.

An adult male and females of this rare and striking looking 

 species were found at Hyde on June 28th, 1888, by F. 0. P. 

 Cambridge.

Adults of both sexes found in abundance by F. 0. P. Cambridge 

 near Woolbridge in June, 1888, and also by myself in Morden 

 Park, but sparingly.
