GENUS TAEENTUIA, Sunt. LYOOSA, Blaohw. in part. 



Although it is difficult to draw a sharp line between the 

 spiders of this and the foregoing genus, the present may he 

 distinguished, generally, by the length of the anterior row of 

 eyos, being a little shorter (certainly not longer) than the second 

 row. 



The facies is high and very broad towards the falces, and the 

 sides of the caput are strongly convex. The legs are generally 

 strong, and but little attenuated at their extremities. Tho ocular 

 area is at least as long as it is broad, and the interval between 

 the anterior row of eyes and the falces (i.e., the height of the 

 clypous) is usually groater than in IVochosa. 



Tho spiders of this group may be usually found running in 

 sunshine ; six species are at present known in Great Britain, 

 but of these, four only have as yet been found in Dorsetshire.

The length of the male is from 2| to 3J lines, and of the 

 female from 4 to 5 lines. 



The sides of the cephalo-thorax are dark-brown, with a marginal 

 band of yellow-brown, and a broad, longitudinal, central one 

 of the same hue, clothed with yellowish-groy pubescence; the 

 central band is of very nearly uniform width throughout, and 

 has no lateral constrictions; a short, longitudinal, red-brown 

 line shews the thoracic junction. 



The legs are strong, of a yellowish red-brown colour. ; the 

 femora markod with brown spots and markings ; in males the 

 femora and tibico of the first pair, and the femora of the second, 

 are of a black-brown colour,
