og liar Formen af en stump Forhoining, uden Spor af
Pigment eller Lindser. Forfra eller liagfra seet (Fig. 2 d)
viser den sig jevnt afrundet i Enden, med et lidet
tand-formigt Fremspring til hver Side.
Snabelen (se Fig. 2 c) er af særdeles betydelig
Størrelse, omtrent saa lang som de 3 förste Segmenter
tilsammen, og er altid stærkt ombøiet mod Bugsiden. Den er,
som hos foregaaende Slægt, bevægeligt artiçuleret til et
fra Hovedsegmentet fortil udgaaende Skaft; men dette Skaft
(se Fig. 2 b) er her særdeles kort og kan derfor let
forbi-sees. Snabelen er stærkt indknebet ved Basis og udvidet
paa Midten, næsten af pæredannet Form, og har en svag
Indsnøring i sit basale Parti, medens det terminale Parti
jevnt afsmalnes mod den stumpt afkuttede Spids. 1
Tværsnit er Snabelen (se Fig. 2 f) næsten trekantet, idet det
dorsale Længdesegment er stærkt, næsten tagformigt hvælvet,
medens de 2 Sidesegmenter stoder sammen ventralt i samme
Plan. Mundaabningen (se Fig. 2 e) er begrændset af 3
distincte Læber, hver med et lidet knudeformigt Fremspring
1 Midten.
Saxlemmerne (se Fig. 2 a, 2 b, 2 c, Fig. 2 g) er
meget smaa og rudimentære, neppe halvt saa lange som
Hovedsegmentet, med hvilket de synes at være ubevægeligt
forbundne. Skaftet er enleddet, cylindriskt og ganske svagt
krummet, samt, foruden de overalt paa Kroppen
forekommende mikroskopiske Sniaatorner, besat med en Del
temmelig smaa og simple Børster. Haanden (Fig. 2 h) er
yderst liden, af triangulær Form og ender med et
indadrettet stumpt Hjørne. Fortil har den en uregelmæssigt
tandet Knude, der er forbundet med Haanden ved et
tyndhudet Parti og forestiller et Rudiment af den bevægelige
Finger. Hos yngre Individer, der dog paa det nærmeste
har opnaaet sin definitive Størrelse er Haanden (se Fig.
2 i, 2 k), som hos foregaaende Slægt, fuldkommen
cheli-form, med stærkt krummede, kloformige Fingre, uden
Sidetænder.
Folerne (se Fig. 2 a—c, Fig. 2 1) er af meget
betydelig Længde, idet de, lige udstrakte, næsten er saa
lange som hele Legemet, naar Snabelen fraregnes. I sin
Bygning stemmer de forøvrigt temmelig noie overens med
samme hos foregaaende Slægt og er, som hos denne,
tydeligt 10-leddede og stærkt zigzag-formigt boiede. Af Led-,
dene er ogsaa her de 2 torste meget korte, hvorimod 2det
og 5te Led er stærkt forlængede og indbyrdes næsten af
ens Længde. Endedelen er omtrent saa lang som 4de
Led og har 2det Led betydelig længere end de øvrige.
De falske Fodder (se Fig. 2 c, Fig. 2 m) er stærkt
forlængede og spinkle, lige udstrakte vel saa lange som
Legemet, naar Snabelen fraregnes, og bestaar af 10 vel
begrændsede Led. Hos Hannen (Fig. 2 c) er 4de og 5te
Led noget bredere end hos Hunnen (Fig. 2 ni) og besatte
med omboiede tornformige Borster. Endedelen (se Fig.
2 n) er næsten saa lang som de 2 foregaaende Led
tilsammen og har 1 ste Led stærkt forlænget. Tornerue paa
de følgende Led (Fig. 2 o) viser et lignende Udseende som
anteriorly and has the form of a blunt prominence, without
trace of pigment or lenses. Viewed anteriorly or posteriorly,
(fig. d) it shews itself to be evenly rounded at the end,
with a small dentiform prominence on each side.
The proboscis (see fig. 2 c) is of particularly large
size, about as long as the 3 first segments together, and
is always strongly incurvated towards the ventral side. It
is, as in the preceding genus, flexibly articulated to a scape
issuing from the front of the cephalic segment; but this
scape (see fig. 2 b) is here particularly short and may
therefore be easily unobserved. The proboscis is greatly
constricted at the base and expanded at the middle,
almost piriform, and has a faint constriction in its basal
portion, whilst the terminal portion tapers evenly towards
the bluntly truncated point. In transversal sections the
proboscis (see fig. 2 f) is almost trigonal, as the dorsal
longitudinal segment is strongly, almost roof-like, arcuate,
whilst the 2 lateral segments unite ventrally in the same
plane. The oral aperture (see fig. 2 e) is bordered by 3
distinct lips, each with a small nodular prominence in
the middle.
The chelifori (see fig. 2 a, 2 b, 2 c, fig. 2 g) are
very small and rudimentary, scarcely half as long as the
cephalic segment, with which they appear to be immobily
connected. The scape is single-jointed, cylindrical, ami
quite faintly bent, and is, also, beset with, besides the
microscopical spines that are everywhere present on the
trunk, a number of pretty small and simple bristles. The
hand (fig. 2 h) is extremely small, triangular in form, and
terminates in a blunt corner directed inwards. Anteriorly
it has an irregularly dentated nodule which is connected
to the hand by a membranous part and represents a
rudiment of the mobile finger. In young individuals which
have, however, attained, approximately, their definite size,
the hand is (see fig. 2 i, 2 k), as in the preceding genus,
perfectly cheliform, with strongly bent claw-shaped fingers,
without lateral teeth.
The palpi (see fig. 2 a—c, fig. 2 1) are of very
considerable length, as they, straightly extended, are.
excluding the proboscis, almost as long as the entire body. In
their structure they correspond otherwise, pretty closely
with the same organs in the preceding genus, and are, as
in it, distinctly 10-jointed, and strongly bent in zig-zag form.
Of the joints tile 2 first are also here very short, while
the 2nd and 5th joints are greatly elongated and are
mutually about uniform in length. The terminal part is
about as long as the 4th joint and has the 2nd joint
considerably longer thai! the others.
The false legs (see fig. 2 c, fig. 2 m) are strongly
elongated and slender, straightlv extended, rather longer
than the body when the proboscis is deducted, and consist
of 10 well marked joints. In the male (fig. 2 c) the 4th
and 5th joints are somewhat broader than in the female.
(fig. 2 m), and are beset with recurvate aculeiform bristles.
The terminal part (see fig. 2 n) is almost as long as the
2 preceding joints taken together, and has the 1st joint
greatly elongated. The spines on the succeeding joints
