forbundet saavel med det foregaaende som efterfølgende
Segment, Paa Rygsiden tælles 6 parvise Knuder foruden en
Del meget smaa saadanne. De 2 folgende Segmenter er,
navnlig hos den ægbærende Hun, noget bredere end de
øvrige og indbyrdes fastere forbundne, dannende tilsammen
ligesom et eget Kropsafsnit, fra hvis Underside den af 4
store mod hinanden boiede Plader bestaaende Brystpose
rager frem; ethvert af disse Segmenter viser ligeledes oventil
li mere fremtrædende Knuder. 5te Segment, der har en
meget bevægelig Articulation med det foregaaende, er noget
længere end dette, smalest fortil og successivt noget tykkere
mod den bagre Ende. Paa Rygsiden af samme findes som
paa de 3 foregaaende Segmenter 6 parvis ordnede Knuder,
hvoraf de 2 er beliggende helt fortil, de 4 andre nærmere
den bagre Ende. De 2 sidste Kropssegmenter endelig er
ganske korte, stærkt fortykkede noget bag Midten og hvert
forsynet med 4 større, næsten pigformige Knuder, 2 dorsale
og 4 laterale, dannende tilsammen en buet Tværrad.
Bagkroppen er som hos Slægtens øvrige Arter aldeles
rudimentær, kun dannende et lidet knudeformigt Appendix
ved Enden af sidste Kropssegment.
Øinene er meget smaa, runde, med mørkerødt Pigment,
der kun indtager den centrale Del af Øiet.
f ste Par Følere er usædvanlig stærkt forlængede,
næsten af hele Legemets Længde og meget tynde. Af
Skaftets Led er det 2det længst, de 2 øvrige omtrent
indbyrdes af ens Længde. Svøben er næsten dobbelt saa lang
som Skaftet og bestaar af et stort Antal (indtil 26) korte,
med tine og korte Børster besatte Led.
2det Par Folere er kun lidet længere end lste Pars
Skaft og i den bagre Kant besat med lange og stærke
Børsteknipper. Svøben bestaar som sædvanlig af et
længere Segment og et meget kort Endeled.
Mundregionen er fuldkommen ubedækket og springer
frem umiddelbart bag 2det Par Foleres Fæste. De stærke
Kindbakker mangler som hos Slægtens øvrige Arter ethvert
Spor af Palper.
lste Fodpar (Fig. 3 a), der udspringer helt fortil fra
Begyndelsen af 1 ste Kropssegment, næsten midt under
Hovedet, er af den sædvanlige Bygning, med den ydre Del
stærkt sammentrykt og Haanden bredest ved Basis, hvor
den nedentil danner et vinkelformigt fremspringende Hjørne.
2det. Fodpar er langt kraftigere udviklet og udspringer
fra den forreste Trediedel af 2det Segment. Basalleddet
er noget udvidet mod Enden og forsynet med en skarp, i
en tilspidset Fortsats udløbende Kjol. 3die Led gaar nedad
ud i et skarpt Hjorne. 4de Led eller Haandroden er
særdeles lidet, neppe synligt. Derimod er det folgende
Afsnit eller Haanden mægtigt udviklet, længere end alle de
connected both with the preceding and the succeeding
segments. On the dorsal surface, may be counted 6 pairs
of protuberances, exclusive of a number of very small
ones. The 2 succeeding segments, more particularly in
the ovigerous female, are somewhat broader than the rest,
and more firmly connected one with the other,
constituting, as it were, a separate section of the body, from
the under surface of which the marsupium, composed of 4
large plates bent in one against the other, is seen to project;
these segments likewise exhibit above as many as 6 rather
prominent protuberances each. The 5th segment, which is
connected with the preceding by an exceedingly mobile
articulation, attains a somewhat greater length than the latter, is
slenderest anteriorly, and gradually becomes a trifle thicker
toward the posterior extremity. On its dorsal face, are
observed, as on that of the 3 preceding segments, 6
protuberances, arranged in pairs, of which 2 occur far in front,
the remaining 4 near the posterior end. Finally, the 2
last body-segments are quite short, thickly incrassated a
little posterior to the middle, and each furnished with 4
large, well-nigh spiniform protuberances — 2 dorsal and 2
lateral, forming together a curving transversal series.
The posterior division of the body occurs, as in the other
species of the genus, quite rudimentary, constituting merely
a small tuberculiform appendix at the extremity of the
terminal body-segment.
The eyes are very small, round, with a dark-red
pigment occupying the central portion only of the eye.
The 1st pair of antennæ are remarkably produced,
equalling almost the whole body in length, and very slender.
Of the joints of the peduncle, the 2nd is longest; the 2
others are about equal in length. The flagellum attains
nearly double the length of the peduncle, and consists of a
large number of articulations las many as 26), beset with
delicate and short bristles.
The 2nd pair of antennæ are but very little longer than
the peduncle of the 1st pair, and furnished along the
posterior margin with long and powerful fascicles of bristles.
The flagellum consists as usual of a comparatively long
segment and a very short terminal joint.
The buccal region is wholly uncovered, and juts out
immediately posterior to the origin of the 2nd pair of
antennæ. As in the other species of the genus, the powerful
mandibles do not exhibit the slightest trace of a palp.
The 1st pair of legs (fig. 3 a), originating on the
foremost part of the 1st body-segment, almost immediately
under the middle of the head, have the usual structure,
the outer part being strongly compressed and the band
broadest at the base, where it forms below a projecting
angular corner.
The 2nd pair of legs are much more powerfully
developed. and issue from the anterior third of the 2nd segment.
The basal joint is somewhat dilated towards the extremity,
and furnished anteriorly with a sharp carina, jutting out
as an acute prolation. The 3rd joint protends below as a
sharp corner. The 4th joint, or carpus, is exceedingly
small, well-nigh invisible. On the other hand, the succeeding
