Beskrivelse af Hunnen. Legeinet er (se PL XII, 
Fig. 4) noget forlsenget, men mindre samraentrykt end hos 
foregaaende Art, mod Ryggen temmelig bred og jevnt hvalvct 
og Epimererne forholdsvis lavere, neppe dobbelt saa hoie 
som selve Kroppen. 
Hovedet er ikke meget lrengere end lste Forkrops- 
segment og har Sidehjernerne temmelig stawkt fremsprin- 
gernle og noget tilspidsede, skjondt i mindre Grad end hos 
foregaaende Art. 
4de Par Epimerer er bagtil dybt udrandede og nedenfor 
Udrandningen udtrukne i et skarpt Hjprne. 5te Par er 
betydelig bredere end hoit og af den sEedvanlige tilrundede 
Form. 
3 die Bagkropssegment Sideplader er temmelig store 
og bar dot bagre Hjorne udtrukket i en kort, men skarpt 
tilspidset, ntesten lige Fortsats. 4de Bagkropssegment har 
oventil en tydelig Kjol, der ender bagtil med en kort torn- 
formig Spids. 
lste Par Folere (Fig. 4 a) liar Skaftet kort og tykt. 
iSvoben or noget liengere end Skaftet og sammensat af ca. 
11 Led, hvoraf det lste er meget stort og ligesaa langt 
som de 4 folgende Led tilsammen. Bisvoben er omtrent 
at Svobens lialve Lamgde, meget tynd og 4-leddet. 
2det Par Fplere (Fig. 4 b) er noget liengere end lste 
Par og bar Skaftets 2 sidste Led omtrent af ens Lamgde. 
Svoben er kjendeligt lsengere end paa lste Par og sam- 
mensat af circa 18 Led. 
Munddelene springer tydeligt frem nedenfor lste Par 
Epimerer (se Fig. 4). Deres Bygning er forovrigt (se Fig. 
4 c—f) i alt vmsentligt saa nser overensstemmende med 
samme hos foregaaende Art, at jeg anser en detailleret 
Beskrivelse af dem for overflodig. 
lste Fodpar (Fig. 4 g ) er forholdsvis kort og under- 
sietsigt bygget og tydeligt subclieliformt som hos de tid- 
ligere bekjendtc Aider af Skegten. Sidste Led ellerHaan- 
don er neppe liengere end det foregaaende Led og har ved 
Enden en tydeligt begnendset noget skraa Griberand, mod 
hvilken den korte Endeklo lean slaaes ind. 
2det Fodpar (Fig. 4 li) viser intet sseregent i sin 
Bygning. 
De 2 folgende Fodpar har Endekloen normalt udviklet 
og neppe kengere end Halvparten at sidste Led (se Fig. 4 i). 
Sidste Fodpar (se Fig. 4) er noget kortere end de 2 
foregaaende og liar Hofteleddet som paa disse simpelt ovalt, 
skjondt noget storre, og i den bagre Band tydeligt saug- 
takket. 
Sidste Par Halefodder (se Fig, 4 k ) er mesten noi- 
agtigt af samme Udseende som hos foregaaende Art. 
Description of the Female. — The body (see PL 
XII, fig. 4) somewhat elongate, though less compressed 
than in the preceding species, with the back comparatively 
broad and uniformly arched, and the epimer^ relatively 
shorter, scarcely twice the height of the body. 
The head is not much longer than the 1st thoracic 
segment, and has the lateral corners rather prominently 
projecting and somewhat pointed, — less so however than 
in the preceding species. 
The 4th pair of epimera are hindwards deeply emar- 
ginate, and, below the emargination, produced to a sharp 
corner. The 4th pair are considerably broader than high, 
and of the usual rounded form. 
The lateral plates of the 3rd abdominal segment are 
rather large and broad, and have the posterior corner drawn 
out as a short, but acute-pointed, almost straight projection. 
The 4th abdominal segment has above a distinct carina, 
terminating posteriorly in a short, spiniform point. 
The 1st pair of antennae (fig. 4 a) have the peduncle 
short and thick. The flagellum is somewhat longer than 
the peduncle and composed of about 1 1 articulations, the 
1st very large and equal in length to the 4 succeeding 
ones taken together. The accessory flagellum is about half 
as long as the flagellum, exceedingly thin and composed 
of 4 articulations. 
The 2nd pair of antenna; (fig. 4 c) are somewhat 
longer than the 1st pair, and have the 2 last joints of the 
peduncle well-nigh uniform in length. The flagellum is ap- 
preciably longer than that of the 1st pair, and composed 
of about 18 articulations. 
The oral appendages project distinctly from beneath 
the 1st pair of epimera (see fig. 4). Their structure, for 
the rest (see fig. 4 c — /), agrees in all essential charac- 
teristics so closely with that in the preceding species as, 
in my judgment, to render a detailed description super- 
fluous. 
The 1st pair of legs (fig. 4 g) are comparatively short 
and thickset in structure, and distinctly subcheliform. as 
in the previously known species of the genus. The last 
articulation, or hand, is scarcely at all longer than the pre- 
ceding joint, and has at the extremity a distinctly defined, 
somewhat oblique palm, toward which the short terminal 
claw admits of being jerked in. 
The 2nd pair of legs (fig. 4 h) exhibit nothing char- 
acteristic in structure. 
The 2 succeeding pairs of legs have the terminal claw 
normally developed, and but very little longer than half 
last joint (see fig. 4 i). 
The last pair of legs (see fig. 4) are somewhat shorter 
than the 2 preceding, and have the basal joint, as in the 
latter, of a simple oval form, though somewhat larger, and, 
along the posterior margin, distinctly serrate. 
The last pair of caudal stylets (see fig. 4 k) have 
almost precisely the same appearance as those in the pre- 
II ceding species.
