af Legemet antager derfor Formen af en oval Skive. 

 Fortil danner Kroppen en kort, triangulær Pandedel, der 

 med hele sin Brede forhinder sig med Snabelen, og ved 

 en stærk Indknihning afgrændser sig fra det bagenfor lig- 

 gende, fodbærende Parti af Kroppen. Om nogen virkelig 

 Hals kan der imidlertid neppe være Tale. Halesegmentet 

 er skarpt afsat fra Kroppen og noget nedadbøiet. Det er 

 mere end halvt saa lang som Kroppen og særdeles smalt, 

 næsten cylindriskt, dog ganske lidt fortykket mod Enden, 

 som er stumpt tilrnndet. 



Snabelen (se Fig. 1, 1 a og lb) er af aldeles enorm 

 Størrelse, næsten dobbelt saa lang som det øvrige Legeme 

 og betydelig tykkere end dette i sit ydre Parti. Den ud- 

 gaar i horizontal Retning fra Enden af Pandedelen, men 

 viser en meget tydelig ventral Bøining (se Fig. 1 h). Af 

 Form er den næsten kolledannet, idet den successivt ud- 

 vides mod Enden, med den øvre Flade stærkt convex, den 

 nedre mere affladet. Enden er stumpt afkuttet og viser 

 3 afrundede Lapper, svarende til de 3 Længdesegmenter, 

 hvoraf den er sammensat. Af disse Lapper er den øverste 

 mest fremragende, og alle 3 begrændser i Midten den tre- 

 kant ede Mundaabning. Denne sidste (se Fig. 1 c) dækkes 

 for en Del af 3 fra hvert af Længdesegmenterne indad 

 fremspringende triangulære Læber af membranøs Beskaf- 

 fen lied, hvis tilspidsede Ender næsten mødes i Midten. 



Øieknuden (se Fig. 1 b) har Formen af en lige opad- 

 rettet koniskt tilspidset Forhøining, uden Spor af Pigment 

 eller Synselementer. 



Af Saxlemmer er ikke det mindste Rudiment at op- 

 dage. 



Følerne (se Fig. 1, 1 a og 1 b), der udspringer noget 

 ventralt fra den forreste Del af Pandepartiet, er af be- 

 tydelig Størrelse, idet de, lige udstrakte. næsten er af Lege- 

 mets Længde. A f Form er de smalt cylindriske. noget 

 S-formigt hoiede og kun besatte i sit yderste Parti med 

 yderst korte pigformige Haar. Leddene viser et lignende 

 indbyrdes Forhold som hos de til foregaaende Familie 

 hørende Former, idet de 2 første er meget korte og tykke, 

 3die og 5te stærkt forlængede, medens det mellem begge 

 liggende 4de Led er forholdsvis af ringe Størrelse. Af de 

 5 ydre Led er 2det længst, og de 3 sidste aftager succes- 

 sivt i Størrelse. 



De falske Fødder (se Fig. 1 a. 1 b) er fæstede tæt 

 bag Følerne og hver indleddede paa en fremspringende 

 Knude. De er stærkt forlængede og tynde, selv betydelig 

 hengere end det hele Legeme, og ialmindelighed stærkt 

 albueformigt bøiede. Antallet af Led er det samme som 

 paa Følerne, nemlig 10, hvoraf de 3 første som sædvanlig 

 er meget korte. 4de og Ste derimod stærkt forlængede. 

 især det sidste. De 4 yderste Led er ganske korte, ind- 

 byrdes omtrent af ens Størrelse, og i Inderkanten bevæb- 

 nede med flere Rækker af korte, sammentrykte Torner. 



between thera. and the central part of the body, therefore, 

 assunies the shape of au oval disc. Anteriorly the trunk 

 forms a short triangular frontal part, which is. in its 

 entire breadth, connected to the proboscis. and is marked 

 off by a strong eonstriction from the pediferous part of 

 the body situated bebind. There can scarcely, however. 

 he any mention of a real neck. The caudal segment is 

 sharply defined from the trunk. and somewhat hent down- 

 wards. It is more than half as long as the trunk and 

 particularly narrow, almost cylindrical, although slightly 

 tumeficated towards the extremity. whicb is bluntly 

 rounded. 



The proboscis (see fig. 1. 1 a and 1 b) is of quite 

 an enormous size, almost twice as long as the rest of 

 the body, and considerably thicker than it in its outer 

 portion. It issues in a horizontal direction from the end 

 of the frontal part. hut exhihits a very distinct ventral 

 curvature (see fig. 1 b). In shape it is almost claviform, 

 .as it is gradually expanded towards the extremity. with 

 the upper surface strongly convex and the lower one more 

 flattened. The extremity is obtusely truncated, and exhihits 

 3 rounded lohes, corresponding to the 3 longitudinal seg- 

 ments of which it is composed. Of those lobes the up- 

 permost one is the most prominent, and all the 3 border 

 in the middle the trigonal oral aperture. This last (see 

 fig. 1 c) is partially covered by 3 triangular lips of mem- 

 hranous nature projecting inwards from each of the longi- 

 tudinal segments whose pointed extremities almost meet 

 each other in the centre. 



The ocular tubercle (see fig. 1 b) has the form of a 

 conically pointed prominence, directed straightly upwards. 

 without traee of pigment or visual elements. 



Not the least rudiment of chelifori can be dis- 

 covered. 



The palpi (see fig. 1, 1 a and 1 b). which issue some- 

 what ventrallv from the anterior part of the frontal por- 

 tion, are of considerable size. as they. straightly extended, 

 are almost the length of the body. In form they are 

 narrow cylindrical, somewhat S-formly hent. and'only in 

 their outermost part beset with extremely short. spinifbrm 

 sgtæ. The joints exhibit a similar mutual relation as T in 

 the forms pertaining to the preceding family, as the 2 

 ones are very short and thick, the 3rd and 5th 'greatly 

 elongated. whilst the 4th joint, lying between them bpth, 

 is relatively of small size. Of the 5 outer joints the 2nd 

 is the longest. and the 3 last ones diminish successively 

 in size. 



The false legs (see fig. 1 a. 1 bi are attached close 

 behind the palpi, and each is articulated to a prominent 

 nodule. They are greatly elongated and thin. even con- 

 siderably longer than the entire body, and usually strongly 

 hent in elbow-shape. The numher of joints is the same 

 as in the palpi, namelv ln. of which the 3 first ones are. 

 as usual. verv short. the 4th and oth. on the contrary. 

 greatly elongated. especially the last-named. The 4 outer- 

 most joints are quite short. about equal in size mutually. 

 and armed on the inner margin with several series of
