2det Par Folere (se Fig. 1). tier udspnnger t;et ne- 
denunder og nogot til den ydre Side af lste Par, er en- 
ormt udviklede, mere end 4 Gauge saa lange som hele 
Legemet, og bestaar som saedvanligt af et 5-leddet Skaft 
og en mangeleddet Svpbe. Skaftets 3 forsto Led er korte 
og tvkke og danner tilsammeu et noget uregelmaessigt for- 
met, koniskt Rodstykke (se Fig. 6 og 7), om hvilket de 
Leddene begrsendsende Suturer slynger sig mere eller min- 
drc tydeligt spiralformigt. Toppen af dette Rodstykke ender 
mod en takket- Rand, der ligesom omfatter den folgende 
Del af Skaftet. Denne, der dannes af de 2 ydre Led, er 
sferdeles staerkt forkenget, rued beggo Led smalt eylindriske, 
indbyrdes omtrent af ens Lrnngde, og i Kanterne besatte 
tried talrige stive Burster og Torner. Svuben er kun ube- 
tydelig laertgere end Skaftet, traadformig og sammensat af 
talrige korte Led. 
Mundregionen er sserdeles staerkt fremspriirgende, saa 
at Hovedet, seet fra Siden (Fig. 2) synes fortil skjaevt af- 
skaaret. Den begraendses fortil fra Panden af en bred, 
halvmaaueformigt buet Plade, der forestiller Epistomet (se 
Fig. 4). 
Overlaeben (Fig. 8), der udgaar fra Midten af den 
ovenomtalte Epistomplade, riser ved Roden oventil en af- 
rundet Forhoining og liar den nedad frit fremragende Del 
naesten af halvcirkeldannet Form, mod Enderanden i Midten 
svagt indbugtet og tint cilieret. 
Underkeben (Fig. 8) bar Endelapperne staerkt diver- 
gerende og af smal tungedannet Form samt i Kanterne taet 
cilierede; imellem dem bemaerkes endnu 2 andre mindre, 
tret saiunien stillede Lapper, imellem hvilke Indgangen til 
Mundhuleu er beliggende. 
Kindbakkerne (Fig. 10 og 11) er sserdeles kraftigt 
udviklede og springer frit from til hver Side af Overlaeben 
(se Fig. 4), overragende denne kjendeligt nedad. Deres 
Corpus er naesten af trekantot Form og articuleret langs 
den ene (ovre) Side til Hovedet. Fra den modsatte Side 
udgaar en triangnlrer Fortsats, hvortil Tyggemusklerne in- 
serer sig. I sin Bevsebning skiller de sig maerkeligt fra de 
ovrige Arter af Slmgten og viser i denne Henseende mere 
Lighed med samme hos Slregten Ilyarachna. Deres Tygge- 
rand er nemlig ganske glat uden tydelige hverken Trend er 
eller Torner, og Tyggeknuden er kun lidet fremtraedende 
samt mangier ganske den saedvanlige riflede Skulptur, i hvis 
Sted kun et yderst lidet Knippe af fine Burster bemaerkes. 
Palpen, der udspringer omtrent fra Midten af Kindbakkernes 
ydre Flade, er sasrdeles smal og bestaar af 3 tydeligt be- 
graendsede Led, hvoraf de 2 furste er simpelt eylindriske 
og temmelig staerkt forlaengede, medens (let sidste er ganske 
lidet og staerkt, naesten leformigt krummet. 
De 2 Par Kjaever (Fig. 12 og 13) er af fuldkommen 
normal Bygning. Paa lste Par (Fig. 12) er den ydre 
Tyggelap kraftigt udviklet og i Enden for sv net med staerke 
Torner, medens den indre Lap er forholdsvis liden og smal. 
The 2nd pair of antennae (see fig. 1), originating im- 
mediately beneath, and a little on the outer side of, the 
1st pair, are prodigiously developed — more than 4 times the 
length of the whole body, and consist, as usual, of a five- 
jointed peduncle and a multi-articulate flagellum. The 3 
first joints of the peduncle are short and thick, and constitute 
together a somewhat irregular -formed, conic basal part 
(see figs. 6, 7), round which the sutures separating the 
joints wind as a more or less distinct spiral. The top of 
this basal part terminates in a jagged margin, that, as it 
were, encompasses the succeeding portion of the peduncle. 
The latter, composed of the 2 outer joints, is very greatly 
produced, with both joints slender-cylindrie, about uniform 
in length, and beset along the edges with numerous stiff 
bristles and spines. The flagellum is hut very little longer 
than the peduncle, filiform, and composed of numerous short 
articulations. 
The oral region projects very prominently, giving to 
the head, when viewed from the side, anteriorly an ob- 
lique, truncate appearance. Forwards, it is separated from 
the front by a broad, lunate, vaulted plate, representing 
the epistome (see fig. 4). 
The labrum (fig. 8), proceeding from the middle of 
the foremention ed epistomial plate, exhibits at the base, 
above, a rounded prominence, and has the freely downward 
projecting part of almost semicircular form, with the term- 
inal margin faintly incurving in the middle, and delicately 
ciliated. 
The labium (fig. 9) has the terminal lobes widely 
diverging, and of a slender, linguiform shape, as also densely 
ciliated along the edges; between the lobes occur, close 
together, 2 smaller ones, and between these is located the 
entrance to the buccal cavity. 
The mandibles (figs. 10, 11) are most powerfully de- 
veloped, and jut freely forward on either side of the labrum 
(see fig. 4), projecting appreciably over it downwards. Their 
corpus is almost triangular in form, and on one side (the 
upper) articulated, up to the head. From the opposite side 
juts out a triangular projection, into which the masticatory 
muscles are inserted. As regards their armature, they differ 
widely from those in the other species of the genus, exhibiting 
in this character a greater resemblance to the mandibles in 
the genus Ilyarachna. Their cutting edge is perfectly smooth, 
without any distinct teeth or spines, and the molar protuber- 
ance hut slightly prominent, as also without a trace of the 
usual fluted sculpturing, in place of which but an exceed- 
ingly small tuft of delicate bristles can be observed. The 
palp, originating about in the middle of the outer surface 
of the mandibles, is exceedingly slender, and consists of 3 
distinctly defined articulations, whereof the 2 first are 
simple-cylindric and rather elongate, the last being quite 
small and strongly curved, almost falciform. 
The 2 pair of maxillae (figs. 12, 13) are quite nor- 
mal in structure. On the 1st pair (fig. 12), the outer mas- 
ticatory lobe is powerfully developed, and furnished at the 
extremity with strong spines, whereas the inner lobe is
