Arts character. Legemet undersretsigt, oventil kort 
haaret, med Sidefortsatseme tret sammentrrengte. Hoved- 
segmentet omtrent saa langt som de 3 folgende Segmenter 
tilsammen, Hal sen kort og tyk. Pandedelen strerkt udvidet. 
Halesegmentet horizontalt, torlrenget, tenformigt. 0ieknuden 
stserkt ophsiet, meget smal, nresten cylindrisk, skraat bag- 
udrettet, Lindserne forholdsvis smaa og beliggende nrer 
Spidsen. Snabelen af Hovedsegmentets Lrengde, cylindrisk- 
konisk. Saxlemmerne betydelig storro end hos foregaaende 
Art og tact haarede; Skaftet smalt cvlindriskt, noget tvk- 
kere i Enden; Haanden licit kortere end Skaftet, noget 
sammentrykt, Palmeu successivt udvidet mod Enden og 
omtrent af Fin'grenes Lamgde, disse strerkt krummede i 
Spidsen, Trenderne i Inderkanten lrengere og tyndere end 
hos foregaaende Art. Fpterne omtrent af Saxlemmernes 
Lrengde tret besatte med temmelig lange Haar, 2det Led 
lrengst, de 2 ydre Led betydelig sinalere end 3die og til- 
sammen noget lrengere end dette, sidste Led aflangt ellip- 
tiskt, kortere end nrestsidste. De falske Fodder omtrent 
af Legemets Lrengde, 5te Led hos Hannen strerkt udvidet 
i det ydre Parti og her besat med talrige lange Bqrster; 
Randtornerne bredt lancetformige, utydeligt. crenulerede i 
Kanterne. Gangfadderne omtrent 3 l /« Gang lrengere end 
Legemet, noget afsmalnende mod Enden og tret besatte 
med temmelig lange og strerke Haar, Laarleddet hos 
Hunnen strerkt opsvulmet, hos Hannen i Inderkanten lint 
crenuleret, 2det Lregled tydeligt afsmalnende, omtrent 3 
Gauge lrengere end det terminate Afsnit; Tarsalleddet 
lrengere end bredt, Fodleddet noget mere end dobbelt saa 
langt, successivt afsmalnende mod Enden og i Inderkanten 
bevrebnet med 4 — 5 tynde Torner; Endekloen betydelig 
lrengere og smalere end hos foregaaende Art; Bikloerne 
meget smaa. De ydre iEgmasser meget store, uregelmres- 
sigt kugleformige, med talrige iEg. Legemets Lrengde 
1 1 1 lt mn ; Spandvidde 70™. 
Bemaerkninger. Denne Art kan nrermest betragtes 
som Type for Slregten, da den i sig paa den mest udprre- 
gede Maade forener de for samme characteristiske Eien- 
dommeligheder. De allerfleste af de under Benrevnelsen 
Nymphon hirtum af andre Forskere anfprte Former refererer 
sig utvivlsomt til denne og ikke til den Kroyerske Art. 
Begge er let at adskille, saavel ved Beskaffenheden af Haar- 
bedrekningen som ved 0ieknuden og Lemmernes Bygning. 
Beskrivelse. Legemets Lrengde hos de storste af 
mig undersogte Individer gaa op til ll 1 / 2 mm , med en Spand- 
vidde af 70™. Hannerne synes som Regel at vrere noget 
mindre end Hunnerne.

Specific Characters. Body thickset, shortly hirsute 
above, with the lateral processes closely crowded. Cep- 
halic segment about as long as the 3 following segments 
taken together, neck short and thick, frontal part much 
expanded. Caudal segment horizontal, elongated, fusiform. 
Oculiferous tubercle elevated, very narrow, almost cylindric. 
directed obliquely backwards, lenses relatively small and 
placed near the point. Proboscis the length of the 
cephalic segment, couico-cylindric. Chelifori considerably 
larger than in the preceding species and densely setous; 
scape narrovv-eylindric, somewhat thicker at the extremity; 
hand somewhat shorter than scape, slightly compressed, 
palm successively expanded towards the extremity and of 
about the length of the fingers, the latter strongly curved 
at the tips, teeth on the inner edge longer and thinner 
than in the preceding species. Palpi about the length 
of the chelifori, densely beset with rather long hairs, 2nd 
joint longest, the 2 outer joints considerably narrower 
than the 3rd, and, taken together, somewhat longer than 
it, last joint oblongo-elliptic , shorter than the penulti- 
mate one. False legs about as long as the body, 5th 
joint in male greatly expanded in the outer part, and 
beset there with numerous long setre, marginal spines 
broad- lanceolate, indistinctly crenulated on the edges. Am- 
bulatory legs about 3 l / 2 times longer than the body, taper- 
ing a little towards the extremity and densely beset with 
rather long and stiff bristles, femoral joint in female 
greatly swollen, in male delicately crenulated on the inner 
edge, 2nd tibial joint preceptibly tapering, about 3 times 
longer than the terminal section; tarsal joint longer than 
broad, propodal joint somewhat more than twice as long, 
tapering successively towards the extremity and armed 
on the inner edge with 4 or 5 slender spines; terminal 
claw considerably longer and narrower than in the pre- 
ceding species; auxiliary claws very small. The outer egg- 
masses very large, irregularly globular, with numerous ova. 
Length of body 11 1 / 2 W " 1 ; extent 70""". 
Bremarks. This species may be chiefly regarded as 
the type of the genus, as it unites in itself, in the most 
distinct manner, the chai-aeters peculiar to the genus. 
Most of the forms recorded by other naturalists under the 
designation Nymphon hirtum, refer unquestionably to this 
and not to the Krover species. They are both easily dis- 
tinguished, alike by the nature of the setous covering, the 
oculiferous tubercle and the structure of the limbs. 
Description. The length of the body in the largest 
of the individuals I have examined reaches the 
extent 70™. The males seem, as a rule, to be somewhat 
smaller than the females.
