Bemserkninger. JSkervrerende Art kjendes fra vore 
tre ovrige Arter: A. longicornis, affinis og pusillus, med 
hvilke den i sin vdre Habitus idethele stemmer overens, 
ved sit ovcutil jevnt og tset knudrede Legeme, den for- 
holdsvis korte Bagkrop og det i Spidsen Iran Met ud- 
trukne Endesegment. 
Beskrivelse af Hunnen. Legemet er (se PI. 9, Fig. 
27 og 28) af den saedvanlige smale og langstrakte Form, 
dog noget kortere end hos den typiske Art, A. longicor- 
nis, idet den storste Brede omtrent er lig 'U af Lfengden. 
Integumenterne er ikke meget faste og paa hele den 
dorsale Flade forsvnede med talrige smaa afrundede Knu- 
der, men uden Haar eller Torner. 
Hovedet er i sin forreste Del temmelig nedtrykt, 
med Panderanden jevnt udrandet og Sidehjornerne ud- 
trukne til tungeformige Lapper. 1 Midten af den ovre 
Flade findes en storre stump Forhoining, der ved en grund 
Lsengdefure er delt i 2. 
At de frie Forkropssegmenter er de 3 forreste ganske 
korte og oven til noget uregelmaessigt knudrede; det lste 
har den forreste Band dybt udrandet for Hovedet og Epi- 
mererne udtrukue i en fortilrettet noget tilspidset Flig. 
4de F orkropssegment er smrdeles stort, indtagende 
mere end l / 3 af Totalkeugden, og viser fortil til hver Side 
et knudeformigt Fremspring lige over det tilsvarende Fod- 
pars Insertion. Hele dets ovre Flade er jevnt og tret gra- 
nulcret af smaa afrundede Tuberkler, medens dets nedre 
Flade er glat og indtages af den mere eller mindre stserkt 
udbuede Brystpose. 
Det bagenfor liggende Parti af Legemet er ved en 
meget bevaegelig Articulation forbundet med dette Segment, 
hvorfor denne Del kan boies saaledes, at den danner en 
storre eller mindre Yinkel med den ovrige Del af Legemet 
(sml. Fig. 32), eller, naar, livad der er det saedvanlige, 
dette bagre Parti er lixeret, kan den forreste Del af Le- 
gemet svinges pendelformigt from og tilbage i Forhold til hint. 
Den forreste Del af dette bagre Kropsparti indtages 
at de 3 bagerste Forkropssegmenter, der oventil er adskilte 
ved dybe, al en blod Hud dte kkede Indsnoringer og derfor 
ogsaa indbyrdes viser en temmelig fri Betsegelighed. De- 
res ovre Side er noget pukkelfonnigt fremspringende og 
furnished at the base with 2 triangular lateral projections. 
Eyes well-nigh triangular, with a dark pigment. First 
pair ot antennae with a compressed, and, in the middle, 
somewhat dilated flagellum. Second pair of antennae, when 
fully extended, almost as long as the body. Colour a 
pale yellowish-grey. Length 14 mm . 
Locality. — Stats. 18, 48, 124, 164, 200. 
Remarks. — The present species may be recognized 
from our three other forms: — A. longicornis, A. affinis, 
and A. pusillus, which exhibit on the whole a rather similar 
habitus, by its having the body, above, uniformly rugged, the 
abdomen comparatively short, and the terminal segment but 
slightly produced. 
Description of the Female. — The body (see PI. 9, 
tigs. 27, 28) of the usual slender and elongate form, though 
somewhat shorter than in the typical species, A. longicor- 
nis, the greatest breadth being about equal to one-fourth 
of the length. 
The integuments, which are not very firm, exhibit 
over the whole of the dorsal surface numerous small 
rounded prominences, but are without either hairs or 
spines. 
The head is a good deal depressed throughout its 
anterior portion, with the frontal margin uniformly emar- 
ginate and the lateral corners produced as linguiform lobes. 
In the middle of the upper surface is seen a large obtuse 
prominence, which, by a shallow longitudinal sulcus, is di- 
vided in two. 
Of the free segments, the 3 anterior ones are quite 
short, and, above, somewhat irregularly rugged ; the 1st 
lias the anterior border deeply emarginate, and the epimera 
produced as anteriorly directed, somewhat acute lobules. 
The 4th segment is exceedingly large, measuring 
more than one-third of the total length, and exhibits an- 
teriorly, on either side, a tuberculiform projection, directly 
above the points of insertion of the corresponding pairs of 
legs. Its entire upper surface is uniformly and closely 
granulous, with small rounded tubercles, while the lower 
surface is smooth, and occupied by the more or less prom- 
inently arched marsupium. 
The succeeding portion of the body is connected, by 
an exceedingly movable articulation, with this segment; 
and the said part admits in consequence of being so bent 
as to form a greater or lesser angle with the rest of the 
body (see fig. 32), or when — which as a rule is the case — 
this posterior part remains fixed, the whole anterior portion 
admits of being swung pendulum-like backwards and forwards. 
The anterior part of this posterior region of the 
body is occupied by the 3 hindermost pedigerous sgments, 
which, above, are separated one from the other by deep 
instrictions, covered with a soft skin; and hence they pos- 
sess in their mutual relation very considerable mobility. 
Their upper side projects in a somewhat hunched form,
