30 Eev. F. O. Pickard-Cambridge on British Spiders. 



spicuous, while rohusta is a much larger spider with hoary 

 grey pubescence, there will not be any great fear of a con- 

 fusion of the three species. 



This fine new addition to the British fauna was first met 

 with at the head of Lake Derwentwater in June 1893, where 

 a male and female were taken from beneath a stone. In 

 May 1894, however, numerous examples were obtained under 

 boards, bricks, &c., in damp meadows in Dorset. 



The female makes a small cell in the damp earth for the 

 spinning of the egg-cocoon, as do most of the other species of 

 Lycosa. I have not received any from other parts of 

 England, but have no doubt that it is abundant in suitable 

 localities throughout the country. 



Lycosa robusta, Sim. (PI. III. figs. 3, 8, 11, 12.) 



Length of male, ceph. 5 millim., abd. 5 millim. or \\ lines ; 

 female, ceph. 7 millim., abd. 8*75 millim. or 7 lines. 



Pubescence hoary white. Abdomen with pale lanceolate 

 mark. Size variable, but much larger than L. spinipalpts. 

 Palpus of male with an apical tarsal claw. Tarsi of first pair 

 of legs of male fusiform, incrassate, clothed with rich black 

 pubescence. 



Fang without any tooth on outer margin. 



Numerous specimens of this fine addition to the British 

 fauna Nvere taken beneath stones on the underclifF at Swanage, 

 between Durlstone Head and Peveril Point; also under 

 stones in the ravines behind the lighthouse. They construct 

 a large cell in the damp loam, sometimes 2 inches long by 

 1 broad, and therein construct the immense white egg-cocoon, 

 hatch and tend the young ones. A dozen or more females were 

 taken, but only one adult male, in May 1894 by the author. 



Lycosa ruricola, De (jeer. 

 (PI. III. figs. 1, 6, 10, 13.) 



Length of male, ceph. 4 millim., abd. 4 millim. or d^ lines ; 

 female, ceph. 6 millim., abd. 9 millim. or 4| to 6^ lines. 



Pubescence yellow-grey. Abdomen with pale lanceolate 

 mark. Size very variable, but smaller than the preceding 

 species. Palpus of male with an apical tarsal claw. Tarsi 

 of first pair of legs of male cylindrical, slender. Fang with 

 a tooth on outer margin. 



!Not uncommon in Dorset and other parts of England. 

 Adult in May and June. 



Lycosa terricola, Th. (PI. III. figs. 2, 11, 14.) 

 Length of male 3*5 millim., abd. 3*5 millim. or 3j lines; 

 female, ceph. 5 millim., abd. 7 millim. or 5^ lines.
