This is a common spider in the woods of Denbighshire and Caernarvon- 

 shire, 



20. Salticus gracilis. 



Salticus gracilis. Hahn, Die Arachn. b. i. p. 73. tab. xviii. fig. 55. 

 Attus gracilis. Walck. Hist. Nat. des Insect. Apt. t. i. p. 423. 



The only locality in which I have met with Salticus gracilis is Gwydir woods 

 in Caernarvonshire. 



Family TnoMisiDiE. 

 Genus Thomisus, Wialck. 



21. Thomisus brevipes.

 Hist. Nat. des Insect. Apt. t. i. p. 503. 



I have found one or two adult females of this species under stones in fields 

 adjacent to woods at Oakland, near Llanrwst, Denbighshire. The only male I 

 ever captured resembled the female in colour; but, though the terminal joints 

 of its palpi were very tumid, the palpal organs were not developed, proving 

 that it had not attained maturity. 



22. Thomisus bifasciatus. 



Xysticus bifasciatus. Koch, Die Arachn. b. iv. p. 59. tab. cxxv. fig. 286, 287, 

 288. 



As there does not appear to be the least necessity for following Koch's ex- 

 ample in separating this spider from the Thomisi, I have retained it among 

 them. 



Adult males may be seen occasionally in July and August running on the 

 ground in pastures near Llanrwst. 



23. Thomisus citreus. 



Thomisus citreus. Walck. Hist. Nat. des Insect. Apt. t. i. p. 526. Latr. Genera
