Lycosa arenicola Cb. 



Length. Male 6 mm., female 8 mm. 



May be distinguished from L. amentata, which it 

 much resembles, by the very narrow central band 

 upon the thorax. The digital joint of the male palpus 

 is furnished with a short curved spine. A rather rare 

 species. 



Lyeosa agricola Thor. {L. Jiuviatih's Bl.) 



Length. 



Very nearly allied to L. arenicola. The central 

 thoracic band, however, is dilated towards its fore 

 ■extremity, and the legs are annulated. Very local. 



Lyeosa annulata Thor. 



Length. Male 5 mm., female 6.5 mm. 



Closely allied to L. amentata. The present 

 -species, however, is smaller, paler, and, as a rule, 

 more distinctly coloured. The palpal organs of the 

 male lack the curved spine found in Z. amentata, 

 this portion of structure being replaced by a short, 

 somewhat oval process. A common species. 



Lycosa nigriceps Thor. 



Length. Male 6 mm. , female 7. 5 mm. 



Ocular area black. Legs never annulated. Pale 

 bands on the cephalo- thorax very broad. Not un- 

 common. 



Lycosa farrenii Cb. 



Length. Male 5 mm., female larger. 

 The radial joints of the male palpi are of a swollen 

 form. Rare. 



Lycosa tra.illii Cb. 

 Length. Male 6 mm., female 8.5 mm. 

 Very similar to L. amentata. Palpus of male 

 terminating with a strong curved spine. Very rare. 



Lycosa proxiraa Koch. 



Length. Male 5 mm. , female 6 mm. 



This spider is very similar in general appearance to 

 Z. amentata. It is, however, smaller, and the palpi 

 of the male are less hairy. The digital joint, too, is 

 more narrow in form. The palpal organs have near 

 their centre a short obtuse process. Rather un- 

 uncommon. 



Lycosa pullata Clk. (Z. obscura Bl. ) 

 Length. Male 5 mm., female 6 mm. 

 This spider is closely allied to Z. proxima, but the 

 legs are less distinctly annulated, and the palpal 

 organs of the male are provided with an oblique 

 spine-like process in place of the obtuse one found in 

 that species. Common. 



Lyeosa prativaga Koch. 



Length. Male 6.5 mm., female 7.5 mm. 



This species is closely allied to Z. proxima. The 

 palpi of the males are long, the digital joint is narrow, 

 and terminates in a strong claw. Near the centre of 

 the palpal organs is a curved pointed spine, which is 



comparatively longer than in the closely related 

 species Z. pnllata. Not common. 



Lycosa lugubris Wlk. 



Length. Male 5.5 mm., female 6.5 mm. 



The thorax of the male is furnished with a broad 

 central band thickly clothed with whitish hairs. The 

 digital joint of the palpus is very narrow, and the 

 palpal organs are small. This species is very common 

 amongst dead leaves, and is almost invariably found 

 in or near woods. 



Lycosa lierbigrada Bl. 



Length. Male 5 mm., female 7 mm. 



The tarsi and metatarsi of the first pair of legs of 

 the male are somewhat swollen. The central thoracic 

 band in both sexes is broad and strongly constricted 

 near its centre. This species is uncommon. 



Lycosa palustris Linn. 



Length. Male 5 mm., female 6.5 mm. 



Very closely allied to Z. herbigrada, but the cen- 

 tral thoracic band is narrow. The separation of these 

 two species is rendered difficult, however, by the 

 occurrence of, apparently, intermediate forms. A 

 common species. 



Lyeosa montieola Clk. 



Length. Male 5 mm., female 6.5 mm. 



This species may be distinguished in the male sex 

 from Z. herbigrada and Z. palust7-is by the tarsi and 

 metatarsi of the first pair of legs being of the normal 

 form and not swollen. A common species. 



Lyeosa purbeekensis F. Cb. 



Length. Male 7 mm., female 9 mm. 



Closely allied to Z. montieola, but usually con- 

 siderably larger in size. The metatarsi of the first 

 pair of legs also are furnished with a large number of 

 long coarse bristles. Local. 



FAMILY OXYOPIDAE. 



The spiders of this family have usually the eight 

 eyes in four unequal rows. The legs are long, fur- 

 nished with numerous conspicuous spines, and are 

 terminated by three tarsal claws. 



GENUS OXYOPES LATR. 



Eyes of front row very small. Second and fourth 

 rows of nearly equal length. Clypeus very high. 

 Legs long and very spinose. 



Oxyopes lineatus Latr. {Sphasus lineatus Bl.) 

 Length. Female 6 mm. , male smaller. 

 This species is the only known representative of 

 the genus in Britain, and is exceedingly rare. 



FAMILY SALTICIDAE. 



The spiders constituting this family are commonly 

 known as " lumping spiders." They may be at once
