which I have had the opportunity of examining (a cT and $ fromParis , with which I have been obligingly favoured by Simon), •:
no white spots are visible on the abdomen, nor are any such spots i
mentioned as distinguishing this species either by Walckknaer, |
C. Koch or Simon, whereas C. Koch has described what he con- 1
siders as a separate species, Pyroph. tyroliensis (loc. cit., p. 29, I
figg. 1097, 1098), in which the abdomen in front of the black half I
of the back has two white spots. But also in ” Pyrod. formicanus ” 1
the colour of the abdomen appears to be variable: Simon says that ■
in the female it ” presente sou vent une ou deux taches fauves trans-verses au dessus des filieres”; Blackwall’s figure of his Salt, formi-carius exhibits a white band broken in the middle just in front of :
the dark posterior portion of the abdomen; and I have received fromMr L. v. Kehfelen two specimens, preserved in spirits, of a Salticus j
from Austria , which agree far better with De Geer’s description and |
figure than my French specimens of Pijrod. formicarius, without t
however appearing to me specifically different from these. ;
In these Austrian specimens (probably imperfectly developed *females) the abdomen is of a pale reddish grey colour, and has be-hind the middle a broad, dark, transverse band almost geminatedby a pale transverse line or patch; lower down, on the sides of theabdomen, this dark hand is dilated in front, and there sends out adark tooth upwards and inwards: between the band itself and these tooth-like portions, the abdomen seems to have been covered with white hair,which probably formed a patch on both sides (as in ”P. tyroliensis ”,according to C. Koch). Behind the broad transverse band, the abdomenis of the same pale colour as in front of it, with two dark patchesor angular lines, one immediately behind the band and one just abovethe anus. In the large pale field before the transverse band, a darkpatch appears on each side (an angular band interrupted in the middle).
The legs are yellowish, with black lines and the metatarsi of thefirst pair black. In one of the specimens the thighs of the 1 st pairhave a dark line on the upper side, and a short similar line on theinside, at the base; the thighs of the succeeding pairs have a blackline on the fore side; the thighs and patellae of the 4 th pair are attheir apices blackish; the tibiae and metatarsi of the 4 a pair havea dark line on the outer side, and (the metarsi at least) a similarline on the inner. In the other specimen the dark lines on the legsare partly effaced and not so distinct. Both specimens appear tome very similar to the spider described by C. Koch as a cf jun. |
