Hovedets Spids; sidste er noget kortere end det foregaa- 
ende. Svpben er omtrent saa lang som Skaftets 2 sidste 
Led tilsammen og bestaar af circa 12 Led. 
Kindbakkerne (Fig, 5 b) er kraftigt udviklede, med 
bred og tydeligt begrsendset Tygeknude. Palpen er derimod 
forholdsvis kort, taft borstebesat. med sidste Led meget 
lidet. 
Underlseben (Fig. 5 c) er temmelig stor, med Side- 
lapperne oxeformigt udvidede i Enden og cilierede i den 
indre Kant. 
lste Par Kjsever (Fig. 5 d) har Tyggelappen stserkt 
indadrettet og paa Enden besat med lange, boiede Torner. 
Basalpladen er liden og forsynet med 2 korte Burster i 
Spidsen. Palpen, der er rettet lige fortil, liar sidste Led 
stort, sammentrykt og noget udvidet mod Enden, der er 
bevsebnet med en Del line Torner. 
2det Par Kjsever (Fig. 5 e) har den ydre Lap noget 
storre end den indre og besat med lange, boiede Burster. 
Kjaevefodderne (Fig. 5 /) er isser udmserkede ved den 
stserke Udvikling af Tyggelappen, der er af halvelliptisk 
Form og rsekker selv til Enden af Palpen; langs dens indre, 
lige Band Andes en Rad af stmrke, kamformigt ordnede 
Tsender, og fra det ovre Hjorne udspringer nogle lange og 
tynde, boiede Burster. 
De 2 forreste Fodpar (Fig. 5 g, h) er af den ssed- 
vanlige spinkle Bygning og tast borstebesatte i begge Kanter. 
2det Par er lidt laengere end lste; forpvrigt er begge Par 
af ens ITdseende, med Haa.nden meget liden og ufuldstsen- 
digt subcheliform. 
De 2 folgende Fodpar (Fig. 5 i ) har 3die Led stserkt 
forlsenget og navnlig paa 4de Par tret besat med lange 
Fjserbprster i den indre Kant. De 2 sidste Led er ind- 
byrdes nassten af ens Lsengde, Endekloen betydelig kortere 
end disse tilsammen. 
5te og 6te Fodpar (se Fig. 5) er temmelig ens byg- 
gede, alene med den Forskjel, at Hofteleddet paa 6te Par 
har ved Basis paa den indre Side en afrundet secundaer 
Lap (se Fig. 5 k). 
Sidste Fodpar (Fig. 5 l ) er som ssedvanlig af kort 
og underssetsig Bygning, med Hofteleddet meget stort samt 
bagtil udvidet til en bred skraat nedadrettot Lap, der er 
afstumpet i Enden og her tret bfrrstebesat. Lappen rtekker 
kjendeligt ud over 3die Led. Sidste Led er pludselig meget 
smalere end de ovrige, linesert og bserer en sylformigt t-il- 
spidset Endeklo. 
At Halefodderne er 2det Par (Fig. 5 ri) ualmindelig 
lidet, neppe mere end halvt saa langt som lste Par (Fig. 
5 to). Sidste Par (se Fig. 5, o) er omtrent af samme 
Lsengde som 2det, men noget tykkere, med kortere og plum- 
pere Basaldel og simpelt lancetformige, nsesten nogne Grene. 
the 3rd extends a little beyond the point of the head ; the 
last is somewhat shorter than the penultimate. The flagel- 
lum attains about half the length of the last 2 joints of 
the peduncle taken together, and has close upon 12 artic- 
ulations. 
The mandibles (fig. 5 b) are powerfully developed, 
with a broad and distinctly marked molar protuberance. 
The palp, on the other hand, is comparatively short, densely 
bristle-beset, and has the terminal articulation very small. 
The labium (fig. 5 c) is rather large, with the lateral 
lobules securiform-expa, tided at the extremity, and ciliate 
along the inner margin. 
The 1st pair of maxillae (fig. 5 d) have the masticatory 
lobe directed prominently inward, and beset at the ex- 
tremity with long, curving spines. The basal plate is small- 
and furnished at the point with 2 short bristles. The palp- 
directed straight forward, has the terminal articulation large, 
compressed, and somewhat dilated toward the extremity- 
which is armed with a number of delicate spines. 
The. 2nd pair of maxilke (fig. 5 e) have the outer 
lobe somewhat larger than the inner, and beset with long, 
curving bristles. 
The maxillipeds (fig. 5 f) are specially characterized 
by the powerful development of the masticatory lobe, semi- 
elliptic in form, and reaching as far even as the end of the 
pal]>; along its straight inner margin occurs a row of strong 
teeth, exhibiting a pectinate arrangement, and from the 
upper corner spring a few long and slender, curving bristles. 
The 2 anterior pairs (fig. 5 g. h ) have the usual 
slender structure, with both [margins densely bristle-beset. 
The 2nd pair are a trifle longer than the 1st; for the 
rest, they present a similar appearance, each having the 
hand very small and imperfectly subcheliform. 
The 2 succeeding pairs (fig. 5 i ) have the 3rd joint 
greatly produced, and — in particular as regards the 4th 
pair — densely beset with long plumous bristles on the 
inner margin. The 2 last joints are almost uniform i' 1 
length; the terminal claw is considerably shorter than both 
taken together. 
The -5th and 6th pairs of legs approximate closely in 
structure, the sole [difference consisting in the basal joint 
of the 6th pair having at the origin on the inner side a 
rounded secondary lobe (see fig. 5 /<:). 
The last pair of legs (fig. 5 l ) are, as usual, short, 
and thickset in structure, with the basal joint very large, 
and, posteriorly, expanded to a broad lobe, pointing ob- 
liquely downward, and truncate at the extremity, where it 
is densely beset with bristles. This lobe projects appreci- 
ably beyond the 3rd joint. The last joint becomes abruptly 
much shorter than the others, is linear in form, and bears 
an awl-shaped terminal claw. 
Of the caudal stylets, the 2nd pair (fig. 5 n) are re- 
markably small, scarcely more than half as long as the 
1st pair (fig. 5 to). The last pair (fig. 5 o) are about equal 
in length to the 2nd. but somewhat stouter, with a shorter 
and more clumsy basal part, and simple lanceolate, well-nigh 
naked branches.
