402 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
I have had opportunities of comparing it with specimens of Salticus floricola (Koch) 
froi the fine collection of Dr. L. Koch, of Nuremberg; the result is, that the present 
species proves to be entirely distinct from S. floricola, with which Mr. Blackwall sup- 
posed it to be identical. It is much smaller, and differs also in the structure of the palpi 
and palpal organs. The description given by Mr. Blackwall of the adult male leaves 
nothing to be desired in that respect; but the figure given (pl. iii. fig. 30) affords little 
assistance to the collector or student. The female differs little from the male, except in 
being less distinctly and brightly marked. There are several varieties of this species; in 
the more common variety the abdomen has the pale, angular, transverse lines or chevrons 
more distinet. The large size and brightness of the two white spots or, rather, patches 
on the hinder part, contrasted with the darker portion, makes this little spider a very 
conspicuous object to the colleetor's eye. Its activity has been noticed (Zool. 1862, 
p. 7945) : its jumps are like those of a flea ora grasshopper; and the only way to capture 
it, without great risk of injury, is to place a hoop-net, held in one hand, on one side of 
it, and then to guide or drive it in, as it were, with the other hand. From the net it is 
safely and easily either bottled or boxed. In fact this is the best way to capture all active 
spiders, especially those of this large family (Salticides), whose colours and markings, 
chiefly depending on hairs and hairy pubescence, are very liable to injury if touched 
with the fingers. 
Excepting the single speeimen from which Mr. Blackwall's description was made, and 
which was captured by myself in Lancashire, it has only been taken on Bloxworth 
heath, where it is not at all rare in some parts. It is as yet unknown on the Continent. 
SALTICUS SCENICUS.

reference, however, to Blackwall.) ; 
This species is found occasionally on walls, but generally on posts and palings. The 
species described and figured in * Brit. and Ir. Spiders,’ by Mr Blackwall, is the Calliethera 
histrionica of Koch, * Die Arachn.' Band xiii. p. 42, pl. 439. figs. 1110, 1111. Indepen- 
dently of differences in colour and markings, the palpus of the male presents well-marked 
differences of structure. I have found it at Oxford not unfrequently ; at Bloxworth it is 
equally common with S. histrionicus; and it seems to be generally dispersed over the 
south of England.

The note upon Salticus scenicus, above, will explain this notice of S. histrionicus.
