10 The Cane Grubs of Australia. 
eolden vellow; pubescence densest laterad and on segmental convexities, 
but nowhere dense; dorsal aspect, prothorax with three set on either 
side of meson and with a clump of sete, not very dense, below cervical 
shield; first lobe of mesothorax with two long set on either side of meson, 
the second with two on either side farther laterad and a few below 
cervical shield, the third without sets; metathoracie lobes with similar 
clothing to those of mesothorax; all sete on thorax long; first lobe of first 
abdominal segment with four long and four very short, stout setzw, second 
lobe with an irregular row of long and short sete; lobes of segments 
2-6 with rather dense, short, stout setw, and a few scattered long sete ; 
7 and 8 without pubescence except for one row of very scattered long 
sete along caudal margin; first lobe of anal segment similar, the second 
with lone set scattered over its surface and at apex with rather dense 
long and short sete. Venter of body; segments of thorax with two or 
three transverse rows of long sete in centre; abdominal segments 1-5 
with one row of scattered long sete 6 and 7 with one seta on either side 
of meson and two laterad; 8 the same but with two sete on either side 
of meson; first lobe of anal segment with about ten long sete in a row, 
the second lobe (except at base) with rather short, stout sete, followed 
ai extreme apex by longer sete. In other respects similar to Xylotrupes. 
Stage I1.—Greatest length, 24 mm.; width in normal curved posi- 
tion, 12 mm.; thickness, 6-5 mm.; width of head, 5-10 mm.; length to: 
apex of labrum, 4-8 mm. 
Second lobe of mesothorax with only one seta on either side of meson ; 
first lobe of metathorax similar, the second with only one farther laterad ; 
first lobe of first abdominal segment with only one seta on either side of 
meson, the second with a row of scattered long sete, consisting of about 
four on either side; 2-6 with sete similar to but not so dense as in Stage 
IIl.; 7 and 8 with one row at caudal margin of six long sete, also first 
lobe of anal segment, the apex of second lobe with only scattered jong 
end short sete; venter of abdominal segments with only one or two 
long sete, the sete at extreme apex not so dense as in III.; peritremes 
more open; otherwise similar to Stage ITI. 
No. 678. 
Stage III.—Greatest length when extended, 34 mm.; width at 
base of anal segment, 9 mm.; length in natural curved position, 17 mm. ; 
thickness, 8 mm.; width of head, 4.75 mm.; length to apex of labrum, 
4-50 mm. 
Very similar to Stage III. of Dasygnathus australis, but the body 
siender and more bluish, the head distinetly smaller; epicranial sclerite 
well separated from the elypeus and with a series of small notches along 
the cephalic margin, about five; second antennal joint not twice as 
long as greatest width (distinctly more so in Dasygnathus) ; the last 
jcint distinctly though not much longer than preceding; prothorax dorsad 
with four sete on either side of meson; first lobe of mesothorax with 
three sete on either side, the second with siz on either side farther 
laterad, the third with one on either side at meson; metathorax similar 
to mesothorax, but third lobe with about three sete on either side; first 
lobe of first abdominal segment with four long and two short sete; 
segments 6-8 ventrad with one row of lone scattered sete; latero-cervical 
shield with an additional seta in centre of cephalic margin, otherwise 
about similar.
