F. P. SMITH OX THE BRITISH SPIDERS OF THE GENUS LYCOSA. 17 



This species is extremely closely allied to L. agricola, Thor. 

 The males usually differ from typical examples of L. agricola, 

 Thor., by all the tarsi being black at the extremity only. The 

 females may, in most cases, be distinguished by the black bars 

 breaking the lateral thoracic bands being narrower, and by the 

 bands being much produced anteriorly, often completely encircling 

 the front part of the head. I have never seen a specimen of L. 

 agricola, Thor., in which they even approach the face. The 

 sternum in the specimen of L. agrestis now before me has broad 

 anterior and lateral bands of a very pale colour, the blackish part 

 being thus reduced to almost a Y-shaped patch. 



This spider is supposed to be exceedingly rare in this country, 

 but may easily have been overlooked on account of its resem- 

 blance to several other species. I have a female of this species 

 which has lain in a tube for years with some examples of L. 

 agricola, Thor. Unfortunately, the exact locality whence it came 

 was not noted, but it is highly probable that it hailed from 

 somewhere in the county of Surrey. It was taken in 1901 

 or 1902. The only other occurrence of this spider in Britain, as 

 far as I know, is the Rev. Pickard-Cambridge's record from 

 Stratford -on- Avon in 1903 (Proc. Dors. F. Ghib). L. agrestis, 

 Westr., seems fairly common on the Continent, and has a wide 

 range — Scandinavia, France, Hungary, etc. Adult in summer.
