ON EUROPEAN SPIDERS. 211 
”nearly horizontal, slender, as long as the cephalothorax, tooth as long.” 
Of the two species adduced, E. faustum and E. palmarum, the first-named 
is made type of the new genus. But that X. faustum is so extremely like 
our European Calliethera histrionica C. KoCH and C. scenica, that I imagine 
it to be identical with one or other of them’), and they must accordingly 
resign their generic name Calliethera for the older name Epiblemum. — E. 
palmarum is perhaps a Plexippus C. KoCH, and certainly does not belong 
to the same genus as Æ. faustum. 
SIMON refers to Calliethera also for inst. the species C. Znfima [-us] 
Sim., which its whole appearance, the spines on its legs, etc. indicate in my 
opinion to belong to Heliophanus C. Koch. 
The male Æpiblemum, like the male Salticus, is distinguished by its 
almost horizontal, projecting mandibles. — The eyes of the 3" row are 
farther from each other than from the margin of the cephalothorax. The 
claws are very long and slender, and the teeth on the inner claw very nu- 
merous (about 15 in Æ. histrionica on the 4" pair), on the outer claw on the 
contrary few (in the above named species about 3); the number is however 
very variable. The hairs of the claw-tufts are gradually somewhat dilated.

The males of this genus, which is easily recognized by its general 
appearance, are usually distinguished, as KocH has already remarked, by 
1) Conf. the description and figure of Æ. faustum in Aran. of the United States 
(Boston Journ. of Nat. Hist., V, p. 367, Pl. XXII, fig. 17). — BLACKWALL, who does 
not consider Æ. histrionicum as specifically different from E. scenicum , includes ” Sal- 
ticus scenicus” in a catalogue of spiders from Canada. (Notice of Spid. capt. by POTTER 
in Canada, p. 34).
