Xysticus bifasciatus (C. L. K.). 
Thomisus bifasciatus, Bl. Spid. Great Brit. and Irel. 
Found on Arthur’s Seat, in June 1861, by Mr Cambridge. 
We have not as yet taken it ourselves in the district, 
Kincraig, in Inverness-shire, being indeed the only Scottish 
locality in which we have detected it. 
Xysticus erraticus (B1.). 
Thomisus erraticus, Bl. Spid. Great Brit. and Ivel. 
This species was also found by Mr Cambridge on Arthur's 
Seat in June 1861. It has been taken at Banchory, in 
Kincardineshire, by Professor Trail, but like the last it is 
evidently a rare spider in Scotland. 
Oxyptila trux (Bl.). 
Thomisus trux,'Bl. Spid. Great Brit. and Irel. 
Apparently not common, but femalesand immatureexamples 
may have occasionally been mistaken for those of the next 
species. Males adult in autumn.

Oxyptila atomaria (Panz.). 
Thomisus versutus+ 7. pallidus, Bl. Spid. Great Brit. and Ivel. 
Appears to be widely distributed and fairly common. We 
have not yet met with the adult male here, but judging by 
Mr Cambridge’s experience in Dorset, and our own in 
Inverness-shire, we may suppose it occurs in May and 
June. ; 
Roadside, Hillend, Feb., ad. @ and two young; Arthur’s Seat and 
Salisbury Crags, March, eight or nine ad, ¢s and as many imm. (Mr 
Cambridge found it in this locality and on the Pentlands in June 1861) ;
