t\'delig ^^lnekl•el•e end hos Hunnen (se Tal). IX, Fig. 

 3 og 4, Tab. X, Fig. B). De 2 Kjonsringe er tyde- 

 ligt adskilte i .«it dorsale Parti og er, ovenfra seede, 

 neppe liredere end Truneus. Deriinod danner de 

 nedad en noget uregelmæssig Udvidning, hvorfra de 

 ydre Kjonsvedliæng ndgaar. Disse sidste er for- 

 holdsvis storre end hos Branchviecta og af noget nær 

 rylindrisk Form, eller kun ganske .svagt afsmalnende 

 mod Enden, og har det ydre Parti tæt besat med 

 rine Haar. Den bagenfor liggende Del, den egent- 

 lige Hale, afsmalne.s gradvis bagtil og er, uligt hvad 

 Tilfældet er hos Hunnen, delt i (i txdeligt begrænd- 

 sede Segmenter, foruden Halegrenene. Disse sidste 

 er fuldkomnien af samme Udseende som hos Hunnen. 



Farve. — Legemet ei' hos begge lyjon i levende 

 Tilstand meget gjennemsigtigt, saa at de indre (Or- 

 ganer mere eller mindre tydeligt .skinner igjenneni 

 de tynde Integunienter. Hos Hunnerne har det ial- 

 inindelighed et svagt gronligt Anstrog, medens det 

 hos Hannerne viser en lys gulagtig Tone. Dog va- 

 i-iercr Farven betydeligt hos begge Kjon efter Tjo- 

 kaliteterne og spiller undertiden over i det blaalige 

 eller rodlige. Hos fuldt udviklede Hunner tindes 

 meget constant (se Tab. IX, F'ig. 1 og 2) paa Ryg- 

 siden af K jonsregionen 2 sidestillede nideformige 

 Pletter af en intensiv ultramarinblaa Farve og ind- 

 fattede af en mørkere Kant. Enhver af disse Plet- 

 ter forlænger sig sædvanligvis fortil i en smal Stribe 

 af samme Farve, og mellem begge disse sees ialmin- 

 ilelighed 2 andre tæt samnienstillede Længdestriber 

 a f en lignende C'oulexir. Den forreste Del af Æg- 

 lieholderen er i Regelen orangefarvet. medens den 

 hagerste Del viser nogle iiregelmæssige violette 

 Shatteringer. De i Ægbeholderen indsluttede Æg 

 er morkt gronfarvede. Hos Hannerne er ofte Sjiid- 

 serne af Gribeantennernes Grrene mere eller mindre 

 tydeligt orangefarvede, og undertiden det bagerste 

 Segment af Halen violet anstroget (se Tab. IX, Fig

hand, is very different to. and much more slender 

 than that of the female (see PI. IX, figs. ;\ and 4; 

 PI. X, rig Hi). The two genital segments are dis- 

 tinctly separated in their dorsal part, and, when 

 seen from above, are scarcely broader than the 

 trunk. Below, however, they form a somewhat irre- 

 gular expansion, from which the external sexual 

 appendages issue. Tlie latter are relatively larger 

 than in Branchinccta. and nearly cylindrical in form, 

 being only ver\- slightly tapei'ed towards the end, 

 and with the outer part covered with tine hairs. 

 The posterior jjortion, or tail projjer, tapers gradu- 

 ally towards the end, and. unlike that of the female, 

 is divide(l into li distiuctly-derined segments, besides 

 the caudal rami. The latter are of exactly the 

 same a])pearance as those of the female. 



Colour. --In the living state, the body in both 

 sexes is very transjiarent, so that the internal or- 

 gans are traceil more or less ilistinctly through the 

 thin integuments. In the females, it has generall\- 

 a faint tinge of green, while in the males, it exhi- 

 bits a light yellow shade. Tiie colour varies, how- 

 ever, considerably in both sexes. ac(;ording to the 

 localities, and scnnetimes has a blue or a red tint. 

 In fully develo])ed females, there is very generally 

 found (see PI. IX. figs. 1 and 2) on the dorsal side 

 of the sexual region, 2 juxtajMised, diamond shaped 

 patches of an intense ultramarine-blue, surrounded 

 by a darker rim. Each of these patches is generally 

 prolonged anteriorly intf) a narrow stripe of the 

 same colour, and between them are generally to be 

 seen two other longitudinal stripes of the same 

 colour, ])laced close together. The anterior portion 

 of the marsupium is. as a rule, orange-coloured, 

 while the ])o.sterior jiart exhibits some irregulai- 

 ])urple markings. The eggs en<'losed in the marsu- 

 ])iuni are of a dark green cfdour. In the males, the 

 tips of the rami of the ])relieusile antenuiP are fre- 

 ([uently more or less distinctly orange-coloured, and 

 the hindmost segment of the tail is often tinged 

 with ]iur]de (see PI. IX. figs. 'r\ and 4). 



IiidiT Organer. 



Tarmen stra'kker sig, som hos Brancliinecla, i 

 l<'orni af et simpelt cylindriskt Ror igjennem hele 

 iiCgemet (se Tab. IX, Fig. 1^4), og er ialmindelig- 

 hcd fvldt mod orangefarvet Indhold, der bagtil grad- 

 vis antager en moi-kere brunagtig Farve. 1 Hovedet 

 udgaar fra Forenden af Tarmroret 2 korte Bliud- 

 sa'kke at' en lignende Structur som hos Branch inrrfa. 

 Spiserøret (Tab. X, Fig. 4, f), o) viser ved sin l''ni'- 

 liindelse med Tarmroret en eiendommelig kla]iformig 

 Indretning, ligesom der paa dette Sted rindes et 

 .Slags chltinagtigt Støtteapparat besat lucd et Antal

Iiitenial Organs. 



.\s in Bidnrliiiiecfd. the intestine runs in the 

 sha])e of a sim])lc lylindrical tube throughout the 

 length of the body (sec Pl. IX, tigs 1 — 4). its con- 

 tents being generally of an orange-colour, grailually 

 assuming a darker brown hue posteriorly. From 

 the anterior end of the intestinal tube, in the head, 

 there issue 2 short cæca of a structure siniiliar to 

 that in Jh-nnchiiiciia. The (csojjhagus (IM. X, rigs. 

 4. f), o) exhibits at its junction with the intestinal 

 tube, a ]ieculiar valve-like arrangement, and also at 

 the same ]dace a kind of chitinous sujiport. clothed 

 with a numl)er of strong, setiform spikes with cili- 

 ated edges, freely projecting inside tiie intestine.
