af Legemet antager clerfor Formen af en oval Skive. 
Fortil danner Kroppen en kort, triangulper Pandedel, dei 
med hele sin Brede forbinder sig med Snabelen, og ved 
en stark Indknibning afgrandser sig tra dot bagenlor lig- 
gende, fodbmrende Parti af Kroppen. Om 'nogen virkelig 
Hals kan der imidlertid neppe vare. Tale. Halesegraentet 
er skarpt afsat fra Kroppen og noget nedadbpiet. Det er 
mere end halvt saa lang som Kroppen og sserdeles smalt, 
nsesten cylindriskt, dog ganske lidt fortykket mod Enden, 
som er stnmpt tilrundet. 
Snabelen (se Fig. 1, 1 a og 1 b) er af aldeles enorm 
Storrelse. nrnsten dobbelt saa lang som det Ovrige Legeme 
og betydelig tykkere end dette i sit ydre Parti. Den ud- 
gaar i horizontal Retning fra Enden af Pandedelen, men 
riser en meget tydelig ventral Boining (se Fig. 1 b). Af 
Form er den nsesten kolledannet, idet den successivt ud- 
vides mod Enden, med den 0 vre Flade strnrkt convex, den 
nedre mere affladet. Enden er stumpt afkuttet og \isei 
3 afrundede Lapper, svareude til de 3 Lamgdesegmenter, 
hvoraf den er sartlmensat. Af diss.e Lapper er den pverste 
mest fremragende, og alle 3 begrsendser i Midten den tre- 
kantede Mundaabning. Denne sidste (se Fig. 1 c) dsekkes 
for en Del af 3 fra hvert af Lsengdesegmenterne indad 
fremspringende triangulscre Lseber af membranes Beskaf- 
fenhed, hvis tilspidsede Ender nsesten modes i Midten. 
Dieknuden (se Fig. 1 b) har Formen af en lige opad- 
rettet koniskt tilspidset For homing, uden Spor af Pigment 
eller Synselementer. 
Af Saxlemmer er ikke det mindste Rudiment at op- 
dage. 
Folerne (se Fig. 1, 1 a og 1 b), der udspringer noget 
ventralt fra den fofreste Del af Pandepartiet, er af be- 
tydelig Storrelse, idet de, lige udstrakte, nsesten er af Lege- 
mets Lsengde. Af Form er de smalt cylindriske, noget 
S-formigt boiede og kun besatte i sit yderste Parti med 
yderst korte pigformige Haar. Leddene viser et lignende 
indbyrdes Forhold som hos de til foregaaende Familie 
horende Former, idet de 2 forste er meget korte og tykke, 
3die og 5te stserkt forlsengede, medens det mellem begge 
liggende 4de Led er forholdsvis af ringe Storrelse. Af de 
5 ydre Led er 2det lrengst, og de 3 sidste aftager succes- 
sivt i Storrelse.

De falske Fodder (se Fig. 1 a, 1 b) er hestede tset 
bag Folerne og liver indleddede paa en fremspringende 
Knude. De er atmrkt forlsengede og tynde, selv betydelig 
hengere end det hele Legeme, og ialmindelighed stserkt 
albueformigt boiede. Antallet af Led er det samme som 
paa Folerne, nemlig 10,, hvoraf de 3 forste som smdvanlig 
er meget korte, 4de og 5te derimod staerkt forlsengede, 
ismr det sidste. De 4 yderste Led er ganske korte, ind- 
byrdes omtrent af ens Storrelse, og i Inderkanten bevseb- 
nede med here Rsekker af korte, sammentrykte Torner. 
between them, and the central part of the body, therefore, 
assumes the shape of an 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 constriction from the pediferous part of 
the body situated behind. There can scarcely, however, 
be any mention of a real neck. The caudal segment is 
sharply defined from the trunk, and somewhat bent down- 
wards. It is more than half as long as the trunk and 
particularly narrow, almost cylindrical, although slightly 
tumeficated towards the extremity, which is bluntly 
rounded. 
The proboscis (see fig. 1, la and l b) is of quite 
an enormous size, almost twice as long as the Test 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, but exhibits 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 exhibits 
3 rounded lobes, 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- 
branous 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 trace 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 ventrally 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 bent, .(and only in 
their outermost part beset with extremely short, spiniform 
setm. The joints exhibit a similar mutual relation as in 
the forms pertaining to the preceding family, as the 2 
ones are very short and thick, the 3rd and 5tli greatly 
elongated, whilst the 4th joint, lying between them both, 
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 b) 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 
bent in elbow-shape. The number of joints js the same 
as in the palpi, namely 10, of which the 3 first ones are, 
as usual, very short, the 4th and 5th, 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
