Bemærkninger. Nærværende Art kjendes fra vorr 

 tre øvrige Arter: A. longicornis, affinis og pusillus, med 

 hvilke den i sin ydre Habitus idethele stemmer overens, 

 ved sit oventil jevnt og tæt knudrede Legeme, den for- 

 holdsvis korte Bagkrop og det i Spidsen kun lidet ud- 

 trukne Endesegment, 



Beskrivelse af Hunnen. Legemet er (se Pl. 9, Fig. 

 27 og 28) af den sædvanlige smale og langstrakte Form, 

 dog noget kortere end hos den typiske Art, A. longicor- 

 nis. idet den største Brede omtrent er lig l /i af Længden. 



Integumenterne er ikke meget faste og paa hele den 

 dorsale Flade forsynede med talrige smaa afrundede Kun- 

 der, men uden Haar eller Torner. 



Hovedet er i sin forreste Del temmelig nedtrykt. 

 med Panderanden jevnt udrandet og Sidehjørnerne ud- 

 trukne til tungeformige Lapper. I Midten af den ovre 

 Flade tindes en større stump Forhøining, der ved en grund 

 Længdefure er delt i 2. 



Af de frie Forkropssegmenter er de 3 forreste ganske 

 korte og oventil noget uregelmæssigt knudrede; det Iste 

 har den forreste Rand dybt udrandet for Hovedet og Epi- 

 mererne udtrukne i en fortilrettet aoget tilspidset Flig. 



4de Forkropssegment er særdeles stort, indtagende 

 mere end '/a ai Totallængden, og viser fortil til hver Side 

 et knudeformigt Fremspring lige over det tilsvarende Fod- 

 pars Insertion. Hele dets øvre Flade er jevnt og tæt gra- 

 nuleret af smaa afrundede Tuberkler, medens dets nedre 

 Flade er glat og indtages af den mere eller mindre stærkt 

 udbuede Brystpose. 



Det bagenfor liggende Parti af Legemet er ved en 

 meget bevægelig Artieulation forbundet med dette Segment, 

 hvorfor denne Del kan boies saaledes, at den danner en 

 større eller mindre Vinkel med den øvrige Del af Legemet 

 (sml. Fig. 32), eller, naar, hvad der er det sædvanlige, 

 dette bagre Parti er fixeret, kan den forreste Del af Le- 

 gemet svinges pendelformigt frem og tilbage i Forhold til hint. 



Den forreste Del af dette bagre Kropsparti indtages 

 af de 3 bagerste Forkropssegmenter, der oventil er adskilte 

 ved dybe, af en blod Hud dækkede Indsnøringer og derfor 

 ogsaa indbyrdes viser en temmelig fri Bevægelighed. De- 

 res øvre Side er noget pukkelformigt fremspringende og 



furnished at the base with 2 triangular lateral projections. 

 Eves well-nigh triangular. with a dark pigment. First 

 pair ot antennæ with a compressed, and, in the middle, 

 somewhat dilated flagellum. Second pair of antennæ, when 

 fully extended, almost as long as the body. Oolour a 

 pale yellowish-grey. Length 14 mm . 



Locality. — Stats. 18, 48, 124, 164, 200. 



Remarks. — The present speeies may be recognized 

 from our three other forms: — A. longicornis, A. affinis, 

 and A. pusillus. which exhibit on the whole a råtner similar 

 habitus, by its liaving the body, above, uniformly rugged, the 

 abdomen eomparatively short, and the terminal segment but 

 slightly produced. 



Description of the Female. — The body (sec Pl. 9, 

 tigs. 27, 28) of the usual slender and elongate form. though 

 somewhat shorter than in the typical speeies, A. longicor- 

 nis. the greatest breadth being about equal to one-fourth 

 of the length. 



The integuments, which are not very iirm, exhibit 

 over the whole of the dorsal surface numerous small 

 rounded prominences. but are witbout either hairs or 

 spines. 



The head is a good deal depressed throughout its 

 anterior portion, with the frontal margin uniforn.lv 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 Ist 

 has 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 tubereuliform 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 orlessprom- 

 inently arched marsupium. 



The succeeding portion of the body is connected. by 

 an exceedingly movable artieulation, 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 (sec 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 aud forwards. 



Tlie 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,
