species of Zycosa in the woods and waste grounds of the south 
of England, as it also is, in similar situations, in most parts of 
France. 
- Fam. Salticides. 
Genus HaAsarius, Simon. 
Hasarius citus. 
Salticus citus, Cambr. Zoologist, 1863, p. 8561. 
An adult male of this spider was kindly sent to me ina 
living state for determination, in 1873, by Mr. F. Smith 
(of the British Museum). This example was found, I 
understood, among the botanical collections in the museum, 
and hence might be considered to have been imported from 
abroad among some dried plants. In October last (1877) 
another adult example of the same sex was received from the 
Rey. A. E. Eaton; this latter example was captured in an orchid- 
house at the Kew Gardens, where it was most probably intro- 
duced with exotic plants. This spider must therefore, so far as 
our present evidence goes, be considered merely an imported 
species. It is very nearly allied to Hasarius Adansonii, 
Savigny, but, I think, is distinct from it. This latter species 
is found in France, Spain, Syria, Egypt, Palestine, Greece, 
Mauritius, and Bombay. I have undoubted examples of H. 
eitus from Manilla; and it is possible that it may eventually 
turn out to be only an unusually distinctly marked variety of 
H, Adansoniti. 
Genus Marprssa, C. Koch. 
Marpessa pomatia. 
Marpessa pomatia, Walck., Simon, Arachn. de France, iii. p. 26.

p- 62, pl. iii. fig. 34. 
I have lately received from M. Simon both sexes of MW. 
pomatia, Walck. ; and, atter a careful comparison of the two, 
I feel no doubt whatever that it is identical with Salticus 
Blackwallit, Clark. The single example found at Southport, 
Lancashire, and which formed the type of Mr. Hamlet 
Clark’s species, still remains the only recorded British speci- 
men. It is also a rare spider in France. The palpi and 
palpal organs of the male are exceedingly remarkable in their 
development.
