CLASSIFICATION 4 I 9 



generic name is really inapplicable, as there are eight eyes, but 

 the anterior laterals are much reduced. The abdomen is long, 

 and the legs are long and unequal, the first pair much the 

 longest and the third much the shortest. 



Fam. 35. Oxyopidae. The Oxyopidae form a well-marked 

 group, with oval cephalothorax somewhat narrowed in front, and 

 lanceolate abdomen. The eight black eyes have a characteristic 

 arrangement, and the anterior medians are always very small. 

 The legs are long and tapering, and not very unequal, and are 

 furnished with particularly long spines, which give these spiders 

 a very characteristic appearance. There are eight genera, of 

 which the most important are Pucetia and .Oxyopes. 



Pucetia contains a number of rather large spiders, generally 

 bright green, often variegated with red. They affect particular 

 plants. For instance, P. viridis, which occurs in Spain, is always 

 found on Ononis hispanica. There are about thirty species of 

 this genus distributed over the tropical and sub-tropical regions 

 of the world. Oxyopes numbers many species, certainly more 

 than fifty, and has a similar distribution, but some uf its members 

 invade colder regions. They are of rather small size. 0. lineatt/* 

 is a very rare spicier in the south of England. 



The Oxyopidae are diurnal spiders, running over plants in 

 search of prey, and often leaping, after the fashion of members of 

 the following family. 



Fam. 36. Attidae (Salticidae). - - Wandering spiders u-ltn 

 cephalothorax broad anteriorly, and bearing eight homogeneous eyes 

 in three roivs. Four eyes, largely developed, are directed for v an I ; 

 the remaining four eyes are placed dorsally in two rows, the first 

 pair being much reduced in size. 



The Attidae or Jumping -spiders form the most extensive 

 family of the whole order, the known species amounting to 

 something like four thousand. It is only of late years that 

 their vast numbers have begun to be realised, for their vagabond 

 habits and m*eat activity enabled them to a great extent to elude 

 the earlier collectors, whose methods were not as thorough as 

 those now in vogue. Their real home is in the tropical regions, 

 temperate fauna being comparatively poor in . \ttid species. 

 France boasts nearly 150, but only .'57 are recorded for the 

 British Isles, and 2 at least of these are recent introductions. 



Some of the tropical forms are most brilliantly coloured,
