Beskrivelse af Hunnen. Legemet er (se PJ. XII, I 
Pig. 5 og 5') ualmiudelig robust bygget og saa steerkt op- 
blaest, at Breden neppe er meget riugere end Hoiden. 
Hovedet er omtrent saa langt som lste Forkropsseg- 
ment og bar Sidehjornern© tilspidsede, men kun lidet frem- 
springende. 
De 4 forreste Par Epimerer er temmelig store, nsesten 
dobbelt saa boio som solve Kroppen ; det 4de viser bagtil 
den ssedvanlige Udrandning og danner nedenfor denne et 
mesten retvinklet Hjorne. 
3 die Bagkropssegments Sideplader er bagtil uddragne 
i en skarp opadkrummet Spids. Dot folgende Segment er 
oventil bag Midten noget indtrykt, forovrigt ligesom de ov- 
rige glat og uden Kjol oiler Portsatser. 
0inene er tydeligt udviklede, af oval Porni og noget 
bredere nedentil. Deres Pigment var Iros det levende Dyr 
af zinoberrod Farve. 
lste Par Folere (Pig. 5 a) bar Skaftet stau'kt op- 
svulmet. Svoben er kun lidet keugerc end clette og bestaar 
at circa 10 Led, hvorat dot lste er meget stort og omtrent 
saa langt som de 4 folgende tilsammen. Bisvoben er for- 
boldsvis stserkt udviklet, adskilligt mere end lialvt saa lang 
som selve Svoben og bestaar af 4 Led; ogsaa her er lste 
Led meget stort og lsengere end de ovrige tilsammen. 
2det Par Folere (Pig. 5 b ) er neppe synderligt lam- 
gere end lste Par og har Skaftets sidste Led noget kortere 
end det forcgaaende. Svoben er omtrent af samiuc Lasngde 
som Skaftets 2 sidste Led tilsammen og sammcnsat af kun 
7 Led. 
Munddelene er for storste Dolen til Siderne diekkede 
at lste Par Epimerer. Deres Bygning stemmer (se Pig. 
5 o -J ) i alt vmsentligt fuldkommen overens med samme 
hos de 2 ovenfor beskrcvne Anonyx-Astvr. 
lste Podpar (Fig. 5 g) viser stor Lighed med samme 
hos Anonyx typMops. Ligesom hos denne er det under- 
ssetsigt bygget, med sidste Led neppe lsengere end det fore- 
gaaende og tydeligt subcheliformt. 
2det Podpar (Pig. 5 h) viser neppe nogen paafaldende 
Eiendommelighed. 
De 3 bagre Podpar (se Pig. 5) er temmelig korte og 
robuste, dog paa langt n;or ikke som hos 0. plant its. Deres 
Hofteled er staerkt jfladeformigt udvidet, ovalt og i den 
bagre Kant tydeligt saugtakket. 
Halefodderne (se Pig. 5 i) er robuste, med lancet- 
formige, borstelose Grene. Paa de 2 forste Par er Stam- 
men i den ydre Kant forsynet med en Rad af tine Torner, 
som derimod mangier paa sidste Par. 
Halevedlnenget (ibid.) er den encste Del, som viser 
nogon mere ioinefaldonde Afvigclse fra samme hos de 2 
toregaaende Arter og er ogsaa den Character, der har 
Description of the Female. — The body (see PL 
XII, tigs. 5, 5') uncommonly robust in structure, and so 
inflated, that the breadth is but very little, if at all, less 
than the height. 
The head is about as long as the 1st thoracic seg- 
ment, and has the lateral corners pointed, though very slightly 
projecting. 
The 4 anterior pairs of epimera are rather large, 
almost twice as high as the body itself; the 4th pair ex- 
hibit posteriorly the usual emargination, below which they 
form an almost rectangular corner. 
1 he lateral plates of the 3rd abdominal segment are 
produced posteriorly to a sharp, Upward-curving point. The 
succeeding segment is somewhat impressed above, posterior 
to the middle; for the rest smooth, like the others, and 
without either keel or projection. 
The eyes are distinctly developed, oval in form, and 
somewhat broader below. Their pigment, in the living 
animal, was a rich Vermillion. 
The 1st pair of antenme (fig. 5 a) have the peduncle 
greatly swollen. The flagellum is but very little longer 
than the peduncle, and consists of about 10 articulations, 
the 1st exceedingly large and well-nigh as long as the 4 
succeeding articulations taken together. The secondary 
flagellum is comparatively well developed, considerably more 
than half as long as the flagellum itself, and composed of 
4 articulations; here, too, the 1st articulation is very large, 
and longer than all the rest taken together. 
The 2nd pair of antennae (tig. 5 b) are not much 
longer than the 1st, and have the last joint of the ped- 
uncle somewhat shorter than the preceding. The flag- 
ellum is about equal in length to the last 2 joints of the 
peduncle taken together, and consists of only 7 articula- 
tions. 
The oral appendages are in greater part covered at 
the sides by the 1st pair of epimera. Their structure (see 
fig- 0 c — j ) agrees in all essential characteristics with that 
in the 2 Anonyx species described above. 
The 1st pair of legs (fig. 5 g ) exhibit great resem- 
blance to tln i corresponding pair in Anonyx typhlops. They 
are, namely, thickset in structure, with the last articulation 
b ut very little, if at all, longer than the preceding, and 
distinctly subcheliform. 
The 2nd pair of legs (fig. 5 h) exhibit apparently no 
striking peculiarity. 
The 3 posterior pairs of legs (see fig. 5) are rather 
short, and robust in structure, though by no means to the 
same extent as in 0. plctutus. The basal joint is very con- 
siderably lamelliform- dilated, oval, and distinctly serrate 
along the posterior margin. 
1 he caudal stylets (see flg. ^5 f) are robust, with 
naked, lanceolate branches. On the 2 first pairs, the trunk 
is furnished along the outer margin with a row of delicate 
spines, wanting on the last pair. 
The telson (ibid.) is the only part that exhibits 
any striking deviation from that organ as it occurs in 
II 2 preceding species, and presents too the character
