minutely spotted -with reddish-brown, runs from tho eyes back- 

 wards. Legs sliort, spinous, and yollowish-brown, mottled 

 with brownish-black. Abdomen largo, depressed, corrugated 

 on tho sides, thinly clothed with short, strong hairs, much tho 

 broadest behind; its colour is yellowish-brown, minutely spotted 

 with red-brown, and with some transverse brownish-black streaks 

 (frequently interrupted in the middle) on tho hindor part of the 

 upper side. Sides irregularly streaked, and spotted with 

 brownish-black. 



Found under stones in fields near Llanrwst, North Wales. [I 

 have never seen an authentic British type of this species, which, 

 in so far at least as British examples are concerned, I suspect 

 strongly to be identical with Xysticus luctuosus (p. 305). At 

 any rate some Dorset examples of the immature male and females, 

 considered by Mr. Blackwall some years ago to be Xysticus 

 brevipes, Hahn., are undoubtedly only examples of Xysticus 

 luctuosus, Bl.]

 Thomisus atomaeitjs, Blachw., I.e. 74, pi. iv., fig. 42. 



Length of the female, l-5th of an inch. 



Cephalo-thorax brownish-yellow, with two dark brown longi- 

 tudinal lines on each side ; the lower ones longest, and parallel 

 to tho lateral margins. Legs and palpi brownish-yellow, 

 minutely spotted with dark brown, particularly on tho upper 

 part. Abdomen depressed, broadest behind, and of a palo 

 roddish-brown colour, freckled with dark brown spots, which 

 are "much [the most numerous on tho upper part, and vary in 

 number, size, and arrangomont in different individuals. 



Found (on tho authority of tho late Dr. Leach) in Scotland. 

 I once met with an example (decided by Mr. Blackwall to belong 

 to this species, X. atomarius) in the New Forest, Hants, but 

 unfortunately it has been lost. It agreed, however, very exactly 

 with the above description, and is, I think, a good species.
