••I':,
ABOUT the middle of June, I obferved the manner of conjunflion in thefe Spiiiers, on the
top of a rocky place, expofed to the fun, where feveral of them were thus engaged. The male
and female, after feveral preludes, by Ikipping towards each other, prefently perceive each
others intentions, and leap with flower motion, tiU at length the male fuddenly fprings on the
female, and placing himfelf in a fomewhat oblique direftion, applies the tip of one of his
arms to the projefting tube of the female, then the tip of the other arm, and thus alternately,
till at length both male and female fpring nimbly away from each other. This fpecies is one
of the fmaller kind of Spiders. Plate 5, fig. 5.
THE eyes are as reprefented by the dots near the figure. The legs whitifli, with black fpots,
unequally long hairs, and black prickles. The thorax oblong, flat, hairy, rather flender
towards the fore-part, black, with a whitifli line drawn through the middle of the thorax, as
it were into the abdomen, and edged with a white border on each fide near the legs. The
abdomen is haiiy, brownifli above, and afli-coloured below. That of the male is nearly
round, orobtufely oval, and rather fmaller than the thorax; that of the female is oblongoval,
larger than the thorax, and flightly undulated.
THE extremities of the arms of the male are reprefented at B. While they are gently
prefled under the microfcope, thofe two little prominences, figured on the inner-part, appear;
of which the anterior is red on the outfide. The arms of the female are cylindric : thofe of
both fexes are brownifli, and have long hairs, briftles, and prickles. The holders are brownifli,
haiiy, perpendicular, and terminate in black claws.

THESE are frequent in diy places, in the middle of June. Plate 4, fig- 7- I ¿id not obferve
them in conjunaion, but as both fexes were ikipping about together, I confidered them
as pairing. This fpecies is rather larger than the former.
THE eyes are fituated as in the preceding Sfiders. The legs are hairy, briftly, and aculeated.
The thorax black, ovate, flender, and carinated towards the fore-part, broad and flat towards
the hind-part. That of the male is thinly fcattered, in patches, with fine down: that of the
female, with brownifli: that of both is marked towards the abdomen with a fomewhat
obfcure facula. The abdomen ovate, black, filky; that of the male, and that of the female,
differ a little from each other as fliewn. The arms of the male are furniflied with the
fexual organs, as at C. Thofe of the female are cylindric: both are coated with hairs of
different lengths. The holders are black, flightly hairy, and perpendicular.

IN the middle of June, the females carry their bags under their bellies, plate 6, fig. 3. At
other times, they frequent nioifl: places, and the banks of fl:reams.
THE eyes are fituated as in the former. The legs are full of hairs, briftles, and prickles.
The thorax black, ovate, flat, flender, and carinated on the fore-part; broad and flat on the
hind-part, and abounding with black hair. The abdomen ovate, black, very hairy; and on
