Segmenter tilsammen, og har paa Midten en stærk Iml- 

 knibning, der danner en meget kort. men tydelig Hals. 

 Det ydre Parti, eller Pandedelen, er særdeles stærkt ud- 

 videt og massivt, 3 Gange bredere end Halsen og dybt 

 rendetbrmigt fordybet efter Midten af den øvre Plade, med 

 Sidedelene stærkt opsvulmede. Halesegmentet er horizon- 

 talt, af smal cylindrisk Form og stumpt afrundet i Spidsen. 



Øieknuden er yderst liden og rudimentær, saa at den 

 let forbisees, og mangler ethvert Spor af Pigment eller 

 Synselementer. Naar Legemet sees fra Siden (Fig. 3 aj, 

 tager den sig ud som et lidet konisk tilspidset Fremspring 

 ved Basis af Halsdelen. Forfra eller bagfra seet (Fig. 3 c) 

 viser den sig imidlertid at danne en tværstillet, bredt af- 

 rundet Flig. 



Snabelen (se Fig. 3 a) er omtrent af Hovedsegmen- 

 tets Længde og noget skjævt nedadrettet. Den afsmalnes 

 successivt mod den stumpt af kuttede Spids og faar derved 

 et udpræget koniskt Udseende. 



Saxlemmerne (se Fig. 3 a, 3 b) er meget kraftigt ud- 

 viklede og, lige udstrakte, omtrent af Kroppens Længde, 

 naar Snabelen og Halesegmentet fraregnes. Skaftet er af 

 cylindrisk Form, dog kjendelig indknebet nær Basis, og 

 rundtom besat med smaa, pigformige Haar. Haanden 

 (Fig. 3 d) er lidt kortere end Skaftet og udmærker sig fra 

 samme hos de øvrige Nymphonider ved sin eiendommelige 

 Form. Palmen er forholdsvis kort, stærkt indknebet ved 

 Basis og af udpræget trekantet Form. Den er noget op- 

 svulmet paa Midten og paa den ydre Flade besat med 

 lignende pigformige Haar som paa Skaftet, især henad 

 Basis af den ubevægelige Finger. Begge Fingre er meget 

 smale og forlængede, omtrent dobbelt saa lange som Palmen 

 og af udpræget klodannet Form. De mangler ganske de 

 sædvanlige Tænder i Inderkanten og er overordentlig stærkt, 

 næsten halvcirkelformigt krummede, endende i sylskarpe 

 Spidser, der krydser hin an den, naar Saxen lukkes. Selv 

 i dette sidste Tilfælde er der dog altid melleni Fingrene 

 en vid Aabning, hvad der har givet Anledning til den af 

 Heller anvendte Artsbenævnelse ..hians". 



Følerne (Fig. 3 e) er betydelig kortere end Saxlem- 

 merne og af et lignende Udseende som hos Sl. Nymphon. 

 De er temmelig tæt besatte med korte Haar, der navnlig 

 i det ydre Parti er meget tine, og har 2det Led længst, 

 de 3 følgende hastigt aftagende i Størrelse. Sidste Led 

 er meget smalt og sammen med næstsidste hengere end 

 3die. 



De falske Fodder er hos begge Kjøn omtrent at ens 

 Længde og, lige udstrakte, ikke fuldt saa lange som Lege- 

 met (se Fig. 3 a). De er hos Hannen (Fig. 3 f) tæt 

 besatte med eiendommelige pigformige Børster, der for det 

 meste er mere eller mindre stærkt omboiede og noget 



ment is of verv considerable size, even appreciably longer 

 than the 3 succeeding segments together, and has a strong 

 constriction in the middle. which forms a very short but 

 distinct neck. The outer portion or frontal part, is par- 

 ticularly greatly expanded and massive. 3 times broader 

 than the neck, and deeply, canalicularly hollowed along 

 the middle of the upper surface, with the lateral parts 

 strongly tumefied. The caudal segment is horizontal. nar- 

 row cylindric in form. and bluntly rounded at the point 



The ocular tubercle is extremely small and rudiment- 

 ary, so that it is easily unobserved, and it is deficient in 

 the slightest trace of pigment or visual elements. When 

 the body is viewed laterally (fig. 3 a) the tubercle appears 

 like a small, conically acuminated projection at the base 

 of the cervical portion. Viewed anteriorly or posteriorly 

 (fig. •"> c), it shows itself to be a transversally placed, 

 broad rounded lobe. 



The proboscis (see fig. 3 a) is about the length of the 

 cephalrc segment, and is somewhat obliquely directed down- 

 wards. It becomes gradually narrower towards the bluntly 

 truncated point. and in this way acquires a distinguished 

 conical appearance. 



The chelifori (see fig. 3 a, 3 b) are very powerfully devel- 

 oped, and, when straightly extended, are al mut the length 

 of the body if the proboscis and caudal segment are de- 

 ducted. The scape is cylindric in form, but appreciably con- 

 stricted near the base, and is beset roundabout with small 

 spiniform hairs. The hand (fig. 3 d) is a little shorter than 

 the scape, and distinguishes itself from the same feature 

 in the other Nymphonids by its peculiar shape. The 

 palm is relatively short, strongly constricted at the base, 

 and of distinguished trigonal form. It is somewhat tumefied 

 in the middle and, upon the outer surface, is beset with 

 similar spiniform hairs as upon the scape, especially to- 

 wards the base of the immobile finger. Both fingers are 

 very narrow and elongated, about twice the length of the 

 palm and of distinguished claw-shaped tunn. They are 

 entirely deficient in the usual teeth on the inner margin, 

 and are extraordinarily strongly bent, almost semi-circularly, 

 terminating in points sharp as awls, which cross each 

 other when the chela is closed. Even in that last case 

 there is always left a witle opening between the fingers. 

 which feature has been the cause of the designation ..hians •• 

 being given to it by Heller, as a speeitic name. 



The palpi (fig. 3 e) are considerably shorter than 

 the chelifori. and are similar in appearance to those of the 

 genus Nymphon. They are rather densely beset with short 

 setæ, which. especially in the outer portion, are very del- 

 icate: the 2nd joint is the longest, aud the 3 succeeding 

 ones diminish rapidly in size. The last joint is very nar- 

 row, and. together with the penultimate one, is longer 

 than the 3rd. 



The talse legs are about equal in length in both 

 sexes. and. straightly extended. are not quite as long as 

 the body (see fig. 3 a). In the male (see fig. 3 f) they are 

 densely beset with peculiar spiniform bristles, which are gener- 

 ally more or less strongly recurvate and somewhat flexuous,
