nitalis) à découvert sous la jambe" (pars tibialis), as distinguishing it from 
Attus, Marpessa, Yllenus and others, which have the "digital enveloppé en 
dessus par le tarse” (lamina bulbi or pars tarsalis) The species of Sımon’s 
Dendryphantes known to me (among which I have however never met with 
the fullgrown 5), namely D, gesticulator SIM. and D. dorsatus C. Kocn 3), 
belong to Attus according to our definition of that genus. OHLERT had al- 
ready previously to SIMON defined the genus Dendryphantes so that D. ha- 
status must be considered as its type, and this determination, which we 
adopt, thus has the right of priority in preference to that which SIMON has 
made for the genus. 
The claws are of the ordinary form, little sinuated, with numerous 
teeth on the inner claw. In D. hastatus on the 1* pair of legs I have 
counted above 20 close-set, very fine comb-teeth, but only 4 coarse and 
distant teeth on the outer claw. In another specimen the inner claw of the 
4" pair had about 18, the outer about 7 teeth. The hairs of the claw-tufts 
are slightly dilated at the extreme apex.

1) In specimens, which I look upon as young males of this species, not only is 
the short tibial joint of the palpus, but also its long tarsal joint enlarged and broader 
than the preceding joints; the inferior and exterior part of the tibial joint is swelled, 
but shows no separate bulbus — all just as in the figures of D. bilineatus (WALCK.), 
which Simon has given loc. cit., Pl. II (VI), fig. 13a, and which therefore appear 
to me to represent the palpus of a not yet fully developed male. In c ad., accord- 
ing to SIMON, the tarsal joint is alike in both sexes, small and cylindrieal, only a 
little longer in the male, whose tibial joint is on the underside incrassated and hol- 
lowed out, and contains the bulbus genitalis(?). Such a relation would indeed, as 
SIMON rightly observes, distinguish these spiders from the other species of the fa- 
mily; it would even separate their from all other spiders, for, as far as we know, 
the bulbus genitalis in all other cases belongs to the tarsal and not to the tibial 
joint. — Also in the younger males of some other Attoidæ, e. g. Menemerus semi- 
limbatus or vigoratus, the palpus has a form like that in the above described species 
of Dendryphantes Sım.: the tibial joint is very short and only indistinctly sepa- 
rated from the long palpal joint: both these joints are broader than the preceding, 
and the tibial joint incrassated on the underside. I suspect that the bulbus genita- 
lis is here formed within the two last joints of the palpus, though, when freed at 
the last change of the integument, it adheres to the tarsal joint.
