below high water mark, between Brighton and Shoreham, in 

 June, 1871. It is a very active and pretty spider, and would 

 hardly fail to be met with in some of the suitable localities round 

 our Southern coasts. 



GENUS HASAEIUS, Simon. 



HASAEIUS ARCUATUS. 



Araneus arcuatus, Cllc, Sv. Spindl., p. 125, pi. 6, tab. 1. 

 Aranea grossipes, De Oeer., Mem. vii., p. 290, pi. 17, fig. 11-14. 

 Salticus grossipes, Cambr., Zoologist 1861, p. 7557, and Trans. 

 Linn. Soc. xxviii., p. 434. 



Length of the male about 2J lines. 



Cephalo-thorax deep black-brown ; ocular area black ; clothed 

 with dull yellowish-red pubescence, and with some white hairs 

 in front and between the eyes of the first row. Hinder slope of 

 the thorax very abrupt. 



Legs very strong, especially those of the first pair ; of a deep 

 black-brown, or black colour ; tarsi and metatarsi reddish 

 yellow-brown, the latter with a black annulus at its fore 

 extremity. 



Palpi short, strong, black ; radial apophysis as long as the 

 joint ; strong, and somewhat obtusely pointed at its extremity. 

 Digital joint rather large, oval ; palpal organs large and 

 prominent but simple in structure. 



Abdomen short, oval, black, thickly covered above and on the 

 sides with somewhat golden-coppery hairs, and rather paler ones 

 underneath. 



The sexes do not appear to differ much in colours. This 

 spider may be easily distinguished from other British species, 

 not only by its colours, but by its short robust form. 



Found (the male only) among rushes in a swamp on the 

 Heath, near Lyndhurst, Hants, and also subsequently near 

 Wokingham, but apparently very rare.
