 , The only individual of this species which has come under my observation, 

 was an adult male, contained in the collection of spiders sent to me from 

 Cambridge by C. C. Babington, Esq., to whose liberality this interesting ad- 

 dition to the Fauna of Great Britain is due.

Distinguished arachnologists have mistaken Dysdera Hombergii, first briefly 

 described by Scopoli (Entomologia Carniolica, p. 403. no. 1 119.), for the young 

 of Dysdera erythrina, from which it differs in colour and organisation. Being 

 convinced of its specific distinctness by a careful examination of specimens 

 captured in 1832, in the same year I gave a description of it in the 'London 

 and Edinburgh Phil. Mag.' vol. i. p. 190, under the appellation of Dysdera La- 

 treillii, but the trivial name, of course, is superseded by that originally given 

 to it by Scopoli. 



Crevices in rocks and walls, and the under side of lichens and liverworts 

 growing on trees, are the favourite resorts of Dysdera Hombergii, which is 

 plentiful in the wooded districts of Denbighshire and Caernarvonshire. The 

 sexes pair in May, and in the succeeding month the female envelops herself 

 in an oval cell of white silk, of a slight texture, on whose exterior surface are 

 disposed minute pebbles, small pieces of indurated soil, and other heteroge- 

 neous materials ; in this cell she deposits between 20 and 30 spherical eggs of 

 a pale pink colour, which are not agglutinated together.

In the 'London and Edinburgh Phil. Mag.' vol. x. p. 100, I proposed the 

 genus Deletrix for the reception of this minute spider, which I described under 

 the specific name exilis from immature females whose colours had been in-
