Beskrivelse af Larven (Praniza). Legemet viser 
(Fig. 12 og 13) den characteristiske tendannede Praniza- 
Form; men forholder sig noget ulige bos ulige store Indi- 
vider. 
Integumenterne er betydelig tvndere end hos den fuld- 
voxno Han, halvt gjennemsigtige samt mangier baade Burster 
og Pigge. Yed staerk Forstorrelse viser de derimod en 
tydelig granulaer Skulptur. 
Hovedsegmentet. er af smal triangular Form, bredest 
bagtil og med en meget benuerkelig Indknibning bag Fo- 
lernes Insertion. Fortil gaar det ud i et tilspidset Nteb, 
der for en stor Del dannes af de eiendommeligt modificerede 
stikkende Munddele. 
Af de 5 Forkropssegmenter er de 2 forste altid meget 
korte forsynede med jevnt afrundede Epimerer. De 3 fol- 
gende Segmenter er kun hos ganske unge Exemplarer (Fig. 
12) tydeligt begramdsede, skjpndt de 2 forreste oventil nsesten 
gansko diekkes af en fra 3die Segment udgaaende skjold- 
fonnig Plade. Hos addre Exemplarer (Fig. 13) er disse 
3 Segmenter fuldstamdigt sammenvoxede med hverandre, 
dannende et sserdeles voluminost og staerkt opbbest Parti, 
der optager det her stserkt udvidede Afsnit af Nmrings- 
kanalen. 
Bagkroppen er forholdsvis kraftigere udviklet end bos 
den fuldvoxne Han, oventil jevnt bvselvet og forsynet med 
jevnt afrundede Epimerer. 
Af 0ine er her ligesaalidt som bos Hannen det mindste 
Spor at opdage; thi de laterale Udvidninger af Hovedet, 
hvor ellers disse Organer bar sin Plads, viser fuldkomnien 
samme Structur som de ovrige Intogumenter og mangier 
ogsaa fuldstaendig Pigment. 
De 2 Par Folere (se Fig. 14) er ilcke i nogen vtesentlig 
Grad forskjellige i sin Bygning fra samme hos Hannen. 
Derimod er Munddelene af et meget afvigende Ud- 
seende. De danner tilsammen (se Fig. 14) et koniskt til- 
spidset, lige fortilrettet Naeb, der aabenbart er indrettet til 
et stikkende og sugende Apparat. Yed nsermere Under- 
sogelse finder man fplgende Dele, der indgaar i Dannelsen 
af Naebbet.

Derpaa folger 2 Par simple stiletformige Munddele, 
der aabenbart er at betragte som de modificerede Kjsever. 
Det lste af disse Par (Fig. 16) er ganske glatte, medens

Spidsen i den indre Kant en fin Tandbevaebning.

Description of the Larva (Praniza). — The body 
(figs. 12, 13) exhibits the characteristic fusiform Praniza 
form, differing however somewhat in examples of unequal 
size. 
The integuments are considerably tbinner than in the 
full-grown male, semi-translucent, and have neither bristles 
nor spikes. Under a powerful magnifier, they exhibit how- 
ever a distinct, granulous sculpturing. 
The cephalic segment is narrow-triangular iu form, 
broadest posteriorly, and with an exceedingly conspicuous 
instriction posterior to the origin of the an ten me. Anteri- 
orly. it protends as a sharp-pointed beak, which, in great 
part, is formed by the peculiarly modified oral appendages. 
Of the 5 segments belonging to the anterior division, 
the 2 first are always exceedingly short, and furnished with 
obtusely rounded epimera. The 3 succeeding segments occur 
distinctly defined in very young specimens only (fig. 12), 
although the 2 foremost axe almost entirely covered above 
by a scutiform plate, proceeding from the 3rd segment. In 
more developed specimens (fig. 13), these 3 segments are 
completely connate one with the other, constituting an ex- 
ceedingly voluminous and swollen part, which serves for 
the reception of the greatly dilated section of the alimen- 
tary canal. 
The posterior division of the body has a comparatively 
more powerful development than in the full-grown male, 
and is uniformly arched above, as also provided with evenly 
rounded epimera. 
Of eyes, not the slightest trace can. as in the male, 
be detected; lor the lateral dilations of the head, on which 
these organs are otherwise located, exhibit the precise 
structure of the other integuments, and, besides, are wholly 
wanting in pigment. 
The 2 pairs of antennae (see fig. 14) do not differ 
essentially in their structure from those in the male. 
On the other hand, the oral appendages present a 
widely deviating appearance. They constitute together (see 
fig. 14) a conically pointed beak, directed straight forward, 
obviously adapted for the purpose of piercing and suction. 
On closer examination, the beak is found to consist of the 
following parts. 
Above, is seen a single, obtusely triangular plate, 
arching over, in part, the remaining appendages, and which 
represents the labrum. 
Immediately beneath this plate, occur a pair of rather 
strong, conically pointed organs (fig. 15), composed of a 
tliickish, muscular basal part, along with an exceedingly 
chitinised, spiniform terminal portion, which, on its inner 
margin, has a number of posteriorly directed teeth. These 
organs are the true mandibles. 
Thence, succeed 2 pairs of simple, styliform oral ap- 
pendages, obviously the modified maxillae. The first of these 
pairs (fig. 1 6) are quite smooth, whereas the somewhat longer 
and more slender 2nd pair (fig. 17) exhibit at the points, 
on the inner margin, a delicate armature of denticles.
