known to me. M. Simon has founded a separate genus, Pisiiw, ■ 

 upon this spider, chiefly in consequence of the different form of 

 the tuberole between the eyes of the lateral pairs. 



GENUS DI^IA, Thor., 



DI2EA DEVONIENSIN, Sp. n. 



Length of an immature female, nearly 2£ lines. 



The cephalo-thorax, legs, palpi, and other fore parts, are of a 

 brownish-yellow colour, tinged with reddish. A rather radiated 

 aroa at the thoracic junction, is suffused with whitish. The meta- 

 tarsi, and the largor portion of the tibiee of the first two pairs, 

 are armed beneath with two parallel, longitudinal rows of spines. 

 Tho eyes of the hind central pair are nearer to each other than 

 each is to the lateral eye next to it. The four central eyes form 

 a squaro, the foro side being a little shorter than the hinder one. 

 The abdomen is oval, of a pale, dull, brownish-yollow hue, mottled 

 with yellowish-white, and with some pale transverse lines along 

 tho middlo of the uppor side. 



The spider above describod was received some years ago from 

 the late Eev. Hamlet Clark, by whom it was found near 

 Torquay. It has been mislaid, and so overlooked until recently. 

 M. Simon, who has examined this specimen, is of opinion that 

 it belongs to an undoscribed species. It is certainly very dis- 

 tinct from any other British Thomisid. Probably, however, the 

 colours have faded since it was caught.

Length of the female, l-5th of an inch. Male, smaller and 

 slenderer. 



Cophalo-thorax large, slightly compressed before, broadly 

 truncated in front, and of a greenish-yellow colour. The legs 

 are of a similar huo ; those of the first and second pairs have two
