450 NOTES ON SPIDERS 



H. penn'cax, Hull-Camb., Proc. Dorset N. H. and A. F. Club, 



1908, p. 173; male, not female. 

 lErigone consimilis, Camb., Proc. Zool. Soc, Lond., 1875, 

 p. 192. 

 The probability of the identity of H. pervicax with H. 

 (Erig07ie) consimilis, Cb., has only very recently been suggested 

 to me by Mr. Pickard-Cambridge. The original type of H. 

 consimilis is still in the British Museum, and the question will 

 be settled as soon as the necessary comparison can be made. 

 The spider described by me in last year's proceedings as the 

 female of H. pervicax is without any doubt H. excisa. The 

 description of the true female, which I have since taken in 

 considerable numbers, is as follows : — 



Total length from 2*6 mm. to 3'i mm. 



Cephalothorax I mm. to 1*3 mm. Greatest depth (at 

 occiput) hardly less than half this length. Clypeus about 

 equal to the ocular space in height. 



Eyes. — Laterals on strong tubercles, oblique, the anteriors 



largest of all ; upper line slightly bowed backward, intervals 



nearly equal ; front medians smallest of all, close together, 

 lateral intervals equal to those of the upper line. 



Legs without femoral or metatarsal spines ; tibial spines 

 slender, two on each tibia, dorsal, uniform in size and strength ; 

 tibiae of the first pair with a lateral spine in front, very slender, 

 within the apical half; tarsus and metatarsus of the first pair 

 equal ; tarsus of the fourth pair two-thirds the length of the 

 metatarsus. 



Abdomen longer than the cephalothorax, oblong-oval, 

 covered with longish hairs. 



Coloration. — Cephalothorax pale greenish brown with 

 indistinct dusky rays ; legs, palpi, falces, yellow tinted with 

 brown ; abdomen greenish, showing traces (in spirit) of narrow 

 transverse bars on the upper surface behind. 



Epigyne rising into a transverse ridge, the summit of which 

 is the strongly wrinkled margin of a transverse oblong cavity
