spiders ; it is probably of extremo rarity in England ; * the 

 only example yet recorded being an adult male found running 

 in sunshino on Bloxworth Hoath, on the 10th of October, 1868. 

 The black undorsido of the abdomen, the almost uniformly- 

 coloured legs, and tho absence of black hairs on the under sides of 

 the tibia) of the first pair, rendor it impossible (independent of its 

 larger size) to mistake this spidor for Tarentula andrenivora, the 

 only other, as yet known, British species with which it could be 

 confused. 



GENUS LYCOSA. PAEDOSA, Sim., and C. L Koch., 

 LYCOSA, Blackw. in part. 



The genus Lycosa may be distinguished from either of the 

 three foregoing genera by the far moro porpendicular sides of 

 tho caput, so that when looked at from in front the breadth just 

 above the falces does not very greatly exceed that of the upper 

 part of the facies. The elypeus is also higher, and tho figure 

 formed by the second and third rows of eyes is more nearly 

 quadrate ; the anterior row is shorter than tho second. The 

 logs are long — 4.1.2.3. — and armed with long spines. The 

 extremities of the legs are much attenuated, but thore is no 

 scopula beneath the tarsi, and the whole spider is well covered 

 with hairs and hairy pubescence. 



This genus comprises the bulk of the true Lycosids, and all of 

 them are small, or of moderate size. They may be found in 

 numberless situations, and at various times of the year accord- 

 ing to the species, some of which are exceedingly abundant. 

 All are very active, and most of them run in sunshine, which 

 appears in some cases to bo so essential to their comfort, that on 

 a sudden obscuration of the sun's rays, even if only for a few 

 moments, every spider disappears among the herbage as though 

 by magic ; and where, immediately before, the surface swarmed 

 with spiders, thore will not bo one visible until the sun again 

 shines out. 



* Since the above was written (September 5-15, 1878) numerous examples 

 of both sexes wore found on Bloxworth Heath, near Woolbarrow.
