2det Par Foleres Blad (Pig. 6) er af betydelig Stor- 
relse, mere end dobbelt saa langt som lste Pars Skaft, og 
af atlang lineser Form, omtrent 5 Gange laengere end bredt. 
Det afsmalnes ganske svagt mod Enden, der er stumpt 
tilrundet, med det ydre Hjorne noget fremspringende og 
forsynet med et kort tandformigt Fremspring. Svubens 
Skaft er omtrent lialvt saa langt som Bladet, smalt cylin- 
driskt, med 2det Led laengst. Endedelen er stserkt forlsenget 
og omtrent af hele Legemets Lsengde. 
Munddelene viser idethele den for Slsegten typiske 
Bvgning. 
Overkeben (Fig. 7, L) er af den saedvanlige, noget 
hjelmdannede Form. 
Underlmben (ibid. 1) er klpftet i to tungeformige, i 
Spidsen jevnt tilrundede og navnlig langs den indre Kant 
tset cilierede Lapper. 
Kindbakkerne (ibid. M) er kraftigt udviklede og har 
den mod Munden vendte Ende Oxeformigt udvidet samt 
noget ulige i sin Beva-bning paa lioire og venstre Side (se 
Fig. 9). Paa venstre Kindbakke Andes fortil to tydelige, 
hinanden delvis dsekkende grovt tandede Plader. og mellem 
disse og den skraat afskaarne Tyggeknude er fsestet 7 tykke 
og bpiede, i den ene Kant fint cilierede Burster. Paa 
hoire Kindbakke kan fortil ligeledes adskilles to tandbse- 
rende (Irene ; men de er lier, navnlig den bagre, forlioldsvis 
mindre og ikke saa grovt tandede. Mellem disse og Tygge- 
knuden bemserkes et afrundet Fremspring, der langs Kanten 
er besat med et stort Antal af fine, bagtil i Lsengde til- 
tagende Torner. Palpen (Pig, 7, p) er forholdsvis temme- 
lig stor, med 2det Led pladeformigt og noget vredent, sidste 
Led, som bos SUegtens pvrige Arter, ganske smalt, naesten 
linesert. 
lste Par Kjsever (Fig. 10) viser intet udmserkende i 
sin Bygning; lain er de paa Enden af den storre Gren 
fiestede Torner ussedvanlig korte og tandformige. 
2det Par Kjsever (Fig. 11) er forboldsvis staerkt ud- 
viklede, med Basaldelen af betydelig Stprrelse og indad 
dannende en noget bnet og tilskjserpet Kant, der er besat 
med en regelmcessig Kad af lange tynde Burster. Tygge- 
lapperne er tilstede i det normale Antal (3) og tset sam- 
mentrsengte ved det indre Hjorne af Basaldelen. Exogna- 
tben er af smal elliptisk Form og langs den ydre Kant 
besat med talrige tset cilierede Burster. Mesognathens sidste 
Led er stserkt indadbpiet, aflangt ovalt og rundt om tset 
borstebesat; de i den ydre Kant fsestede Burster er delvis 
ligesom bos den typiske Art noget tilbageboiede og spar- 
somt cilierede. 
lste Par Kjsevefpdder (Fig. 12) ha,r Basaldelen om- 
trent af samme Lsengde som den Ovrige Del af Stammen 
samt indad forsynet med en smal, tungedannet Tyggelap. 
Sidste Led er kegleformigt tilspidset og ender med en kort, 
men tydelig Klo. Exognathen er her ligesom paa folgende 
The scale of the 2nd pair of antennae (fig. 6) is of 
considerable size, more than twice the length of the peduncle 
of the 1st pair, and oblongo-linear in form, its length ex- 
ceeding about 5 times its breadth. It tapers very slightly 
toward the end, which is obtusely rounded, with the outer 
corner somewhat projecting, and furnished with a short, 
dentiform process. The peduncle of the flagellum, slender- 
cylindric, has about half the length of the scale, with the 
2nd joint longest. The terminal portion is greatly produced, 
equalling about the whole body in length. 
The oral appendages exhibit on the whole the typical 
structure of the genus. 
The labrum (fig. 7 L) has the usual somewhat gal- 
eate form. 
The labium (ibid. 1) is cleft into two linguiform lob- 
ules, uniformly rounded at the point, and, more particularly 
along the inner margin, densely ciliated. 
The mandibles (ibid. M) are powerfully developed, 
with the extremity directed toward the mouth securiform- 
dilated, and differ somewhat in their armature on the right 
and left sides (see fig. 9). On the left mandible, occur an- 
teriorly two distinct, coarsely dentate plates, the one partially 
overlapping the other; and between these plates and the 
obliquely truncate molar protuberance are attached 7 thick 
and curving bristles, along one side finely ciliated. On the 
right mandible, anteriorly, two dentiferous branches can 
likewise be distinguished; but these, in particular the pos- 
terior one, are comparatively smaller and less coarsely 
dentate. Between the branches and the molar protube- 
rance is seen a rounded projection, beset along the margin 
with a large number of slender spines, increasing in length 
posteriorly. The palp (fig. 7, p) is comparatively large, 
with the 2nd joint lamelliform and somewhat twisted, the 
last being, as in the other species of the genus, quite 
slender, almost linear. 
The 1st pair of maxillae (fig. 10) exhibit nothing 
characteristic in their structure, saving only that the spines 
attached to the extremity of the larger branch are unusu- 
ally short, and dentiform. 
The 2nd pair of maxilla; (fig. 11) are comparatively 
well developed, witli the basal portion of considerable size, 
; and forming, inwards, a somewhat arched and sharp edge, 
furnished with a regular series of long and slender bristles. 
Tbe masticatory lobes are present in the usual number (3), 
and placed close together at the inner corner of the basal 
part. The exognath is slender-elliptic in form, and armed 
along the outer margin with numerous closely ciliated bristles. 
The last joint of the mesognatli is greatly incurved, oblongo- 
oval, and densely bristle-beset round tbe edges; the bristles 
attached to the outer margin curve, as in the typical species, 
somewhat backward, and are but sparingly ciliated. 
The 1st pair of maxillipeds (fig. 12) have the basal 
part about of the same length as the remaining section of 
the stem, and, inwards, are provided with a slender, lingui- 
form masticatory lobe. The last joint is conically pointed, 
and terminates in a short, but distinctly developed claw.
