ssedvanligt Udseende og siinpelt cylindriske. Hos Hannen 
(Fig. 5 og 5 b ) udmaerker derimod 3 die og 4de Led sig i 
hoi Grad red sin eiendommelige Udvikling. Begge disse 
Led er her staerkt sammentrykte fra Siderne og jpladefor- 
migt udvidede, samt forbundne med hinanden ved en s;er- 
deles bevaegelig Articulation. 3die Led lober nedad ud i 
cn tungeformig Lap, som, naar 4de Led boies ind, glider 
henad dettes Yderflade. 
Mundregionen er nedad staerkt fremspringende og saa- 
godtsom ganske ubedmkket til Siderne (se Fig. 5 og 5 *). 
Kindbakkerne (Fig. 5 c) er kraftigt udviklede, med 
tydeligt begramdset bred Tyggcknude. Palpen er af bety- 
delig Lamgde og liar sidste Led af oval lancetdannet Form 
samt besat med meget lange og tynde Burster. 
Be 2 Par Kjsevor (Fig. 5 d — e) riser intet udmaer- 
kende i sin Bygning. 
Kjawefodderne (Fig. 5 /) har den indre Tyggelap tem- 
melig stor og i den indre Kant bevaebnet med en Rad af 
Torner. Palpen er forlaenget, med de 2 sidste Led rigeligt 
borstebesatte og Endekloen skarpt tilspidset. 
lste Fodpar er betydelig baade kengere og kraftigere 
bygget end 2det Par. Haanden er stor og bred, men af 
temmelig forskjellig Form hos de 2 Kjon. Hos Hunnen 
(Fig. 5 li) er den omvendt piereformig og temmelig opsvul- 
met ved Basis, mod Griberanden lain ganske svagt ind- 
bugtet i Midten og utydeligt begramdset bagtil, hvor der 
til hver Side er fsestot 3 Tornerj; Endekloen er betydelig 
kortere • end Haanden og af seedvanligt Udseende. Hos 
Hannen er Haanden paa dette Fodpar (Fig. 5 g) sserdeles 
bred og staerkt sammentrykt, med Griberanden bagtil tyde- 
ligt begramdset og forsynet med 2 dvbe Indbugtninger ; 
Endekloen er overordentlig staerkt forlaenget, leformig, og 
lagei, naar den indboies, med Spidsen langt ud overHaan- 
dens Basis eller omtront til 3die Led. 
2det Fodpar (Fig. 5 ?) er fuldkommen ens formet 
hos begge Kjon. Dot er af forholdsvis svag Bygning og 
temmelig rigeligt borste besat, med Haanden meget smal, 
noget laengere end det foregaaende Led og i Enden naesten 
tvrert afkuttet, Endekloen er meget liden. 
De 2 folgende Fodpar er forholdsvis spinkle og kun 
sparsomt borstebesatte, med de 3 yderste Led indbyrdes 
omtrent af ens Laengde og Endekloen ganske kort. 
De 3 bagerste Fodoar har a lie Hofteleddet smalt 
linesert, ikke som ssedvanlig pladeformigt udvidet. Det for- 
reste af disse Par er omtrent saa langt som de 2 foregaa- 
ende Par, medens de 2 sidste er betydelig -stasrkere for- 
lsengede. 
Af Halefodderne er det forreste Par (Fig. 5 k) tem- 
melig kraftigt udviklet, jmed tyk. noget kantet Stamme og 
forholdsvis kortc Grene. Det 2det Par er af sarnme Byg- 
ning, men neppe halvt saa stort. 
(fig. 5 x), the joints of the peduncle exhibit the usual 
appearance and a simple cylindric form. In the male 
(figs. 5. 5 b), on the other hand, the 3rd and 4th joints 
are eminently characterized by their peculiar development. 
Both of those joints are strongly compressed from the sides 
and 1 amelliform-expanded, as also connected by an exceed- 
ingly mobile articulation. The 3rd joint juts out below 
as a liuguiform lobe, which, on bending in the 4th joint, 
slides along the surface of the latter. 
The buccal area projects prominently below, and ' s 
well-nigh wholly uncovered at the sides (see figs. 5, 5 a?) - 
The mandibles (fig. 5 c) are powerfully developed, with 
a broad, distinctly defined molar protuberance. The palp 
is of considerable length, and has the last joint oval-lanceolate 
in form, as also beset with very long and delicate bristles. 
The 2 pairs of maxillae (fig. 5 d — e) exhibit nothing 
characteristic in their structure. 
The maxillipeds (fig. 5 f) have the inner masticatory 
lobe rather large, and armed on the- inner margin with a 
row of spines. The palp is elongate, with the last 2 .joints 
profusely furnished with bristles and the terminal daw 
sharply pointed. 
The 1st pair of legs are at once considerably longer 
and more powerful in structure than the 2nd pair. The 
hand is large and broad, but of somewhat deviating form 
in the two sexes. In the female, it is inverted-pyriform and 
rather swollen at the base, with the palmar margin but 
faintly incurved in the middle and indistinctly defined 
posteriorly, where, on either side, occur 3 spines; the 
terminal claw is considerably shorter than the hand, and 
exhibits the usual appearance. In the male, the hand 
on this pair of legs (fig. 5 g) is very broad and strongly 
compressed, with the palmar margin well defined posteriorly 
and exhibiting 2 dee]) incurvations; the terminal claw is 
remarkably elongate, falciform, and extends, with the point, 
when bent in, far beyond the base of the hand, or near- 
about to the 3rd joint. 
The 2nd pair of legs (fig. 5 ?') occur precisely of a 
similar form in both sexes. These are comparatively feeble 
in structure, and rather abundantly bristle-beset, with the 
hand very narrow, somewhat longer than the preceding 
joint, and well-nigh vertically truncate at the extremity; 
the terminal claw is very small. 
The 2 succeeding pairs of legs are comparatively 
slender, and but sparingly furnished with bristles, the outer- 
most 3 joints occurring about equal in length, with the 
terminal claw' quite short. 
The hindmost 3 pairs of legs have each the basal 
joint narrowly linear, not, as is usually the case, lam el h' 
form-expanded. The anterior of these pairs are about as 
long as the 2 preceding ones, the 2 latter occurring much 
more elongate. 
Of the caudal stylets, the foremost pair (fig. 5 k) are 
rather powerfully developed, having a thick, somewhat angular 
stem and comparatively short branches. The 2nd pair ex- 
hibit h. similar structure, but attain scarcely half the size.
