The Cane Grubs of Australia. 17 
No. 667. 
Stage III. (?)—Greatest length, 25 mm.; vidth, 6 mm.; length in 
natural curved position, 10 mm.; thickness, 5-25 mm.; width of head, 
3-75 mm.; length to apex of labrum, 3-5 mm. 
Differs from No. 646 in that the shafts of the are not parallel 
but somewhat oblique from each other, both the shafts and the branches 
shorter, their sete dense, not scattered and with about twenty setz 
altogether on either side (about fifteen in No. 646). A larger species. 
No. 607. 
Stage Il, (?)—Greatest length, 19 mm.; width at base of anal 
segment, 5 mm.; length in normal curved position, 8 mm.; thickness, 
4-5 mm.; width of head, 2-5 mm.; length to apex of labrum, 2-25 mm. 
Anal orifice very deeply channelled, forming a transverse cleft ; 
when viewed from the side, the abdomen rising abruptly from it, 
situated near apex of dorsal surface, the abdomen squarely truneate 
at apex, not pointed. Epicranial sclerite with about two sete on either 
side of meson in centre. Second antennal joint about as long as the 
other three united. 
No. 658. 
Stage [11.—Greatest length when extended, 25 mm.; width at base 
of anal segment, 6 mm.; length in natural curved position, 11 mm.; 
thickness, 5 mm.; width of head, 4 mm.; length to apex of labrum, 3-75 
mm. 
Epicranial sclerite wholly without sete. Second antennal joint 
with one seta dorsal and one ventrad. Anal orifice with a straight 
incision across base, forming base of triangle (present in No. 650 but 
less distinct), and with an almost straight incision from lateral angle 
of orifice to cephalad of the median anal channel (this very faint in 
No. 650), with a row of very fine sete on either side running near and 
parallel to these incisions, these sete thus forming a V and much finer 
than those surrounding; the surrounding sete dense. Otherwise very 
similar to No. 650. 
No. 609. 
Stage III. (?)—Greatest length, 13 mm.; thickness, 3 mm.; length 
in natural curved position, 6 mm.; width at base of anal segment, 3-10 
mim.; width of head, 2 mm.; length to apex of labrum, 1-75 mm. 
Body colour dilute milky white. Epicranial sclerite without. sete 
along cephalic margin, naked, except for a single seta on each side of 
meson in centre. Apex of abdomen ventrad with a curved bow of about 
twenty sete, these sete stouter and larger than those about them, close 
together, with a naked path caudad of the bow; cephalad of this bow 
are about two irregular rows of short scattered sete. First antennal 
joint longest, a little longer than second, the second joint with a single 
seta dorsad at half its length. 
We have examined several specimens from Gordonvale which alk 
appear to agree in the characters given above but the specimens from 
Harwood Island, Clarence River, N.S.W., differ in that the second 
antennal joint is somewhat longer than the first, and the scattered sete 
cephalad of the anal bow are larger and denser. These three specimens 
probably are a different species.
