NOTES ON SPIDERS 449 



spot, a month later, Mrs. Fletcher, of North Sunderland 

 Vicarage, sent me a fine pair of Typhochraeslus digitatus, 

 Cb., of which species the male had not previously been 

 taken in the county. 

 Z. iieiiiorale was first taken in Northumberland by Dr. 

 Hardy on Cheviot Hill in 187 1. I have recently taken a 

 few examples of both sexes in West Allen at 1,300 feet 

 and upwards. L. paraUelum appears to stop at about 

 800 feet. Figures of the females of these two species 

 (also of Cnephalocotes incurvatiis $) are given in my paper 

 on 'Northumbrian Coast Spiders' in the 'Naturalist,' 

 August, 1909. 



Caledonia evansii Cb, Ninebanks, December, 1908, 

 among grass. One of the latest additions to my 

 Allendale list, which now (June, 1909) numbers 185 

 species. 



Thyreosthenius biovatus Cb. A male and three females 

 were taken from a nest of Formica rufa on the 

 occasion of the Field Meeting at Dipton woods in 

 June, 1909. 



Evansia merens Cb. This spider is probably to be met 

 with anywhere in the low-lying parts of Northumberland 

 and Durham in the nests of Lasius niger or Formica fusca, 

 but in Allendale I have only once taken it, from the nest 

 of the former. In Cleveland, however, at similar eleva- 

 tions it seems to be quite plentiful, for I have received it 

 in considerable numbers from my nephew, Mr. J. W. H. 

 Harrison, of Middlesbrough, who has found it on both 

 sides of the Tees with both species of ant. 



Cornicularia vigilax Bl. An adult male, Whitfield Fell, 

 May, 1909.
