ALLENDALE SPIDERS II5 



Female : 



Total length 2*3 mm. Legs i, 4, 2, 3, but very little differ- 

 ence between i and 4. 



Abdomen dull green, with pale transverse bars visible after 

 immersion in spirits. In this and in its general coloration it 

 resembles the male, but all the metatarsi and tarsi are clouded 

 with black. 



Epigyne characteristic, with a large central process deepl)' 

 grooved in the middle longitudinally. 



Among moss and heather in a pinewood on Whitfield Fell 

 at about 1,400 feet. 



This species resembles L. Why??ipern, F. Cb., in structure, 

 but is much smaller. It is also nearly allied to some 

 Continental species, but readily distinguished by the form of 

 the patellar process of the palpus, by the details of the palpal 

 bulb and of the basal protuberance of the tarsus.
