16 The Cane Grubs of Australia. 
the prothorax thus with three lobes of which 1 and 2 are longest at 
meson, the latter not present laterad (in albohirta, prothorax with only 
two lobes, both with two or more irregular rows of sete of various 
lengths) ; first lobe of mesothorax with about three sete on either side 
of meson, the second with none at meson but with three on either side 
farther laterad, not counting dorsum of segmental convexity, the third 
with one seta on either side of meson (in albohirta, first lobe with two or 
three rows of various-lengthed sete, the second with two or three rows 
laterad, none at meson, the third with one continued row) ; first lobe of 
metathorax with four sete on either side of meson, otherwise similar to 
mesothorax ; abdominal segments similar to those of albohirta but apical 
three segments with fewer seattered sete; venter of body with fewer 
sete; apex of anal segment with the anal path not clearly defined, with 
only about fourteen delimiting sete in a straight row on either side (about 
twenty-eight in albohirta, the path clearly defined) ; body of a uniform 
opaque creamy yellow, the coloured paris much lighter than in 
albohirta. A specics distinct in structural details and also in habits, 
due to its uniform vellowish colour and more flattened form. 
LEPIDIOTA Sp. No. 46. 
Stage I1/.—Greatest length at stretch, 75 mm.; width at base of 
anal segment, 17 mm.; length in natural curved position, 34 mm.; thick- 
ress, 15 mm.; width of head, 12 mm.; length to apex of labrum, 12 mm. 
Very similar to albohirta but much larger; epicranical sclerite finely 
densely rugose or coriaceous, not at all reticulate, the clypeus similar, 
mandibles as in No. 377 but distal teeth of retinaculum on left mandible, 
obtuse; lacinia and galea with more teeth, these longer, more slender 
and somewhat curved at apex; pubescence much sparser but not as sparse 
as in No. 89; first antennal joint with four sete, the second with two; 
anal path as in No. 89 but the delimiting sete longer, meeting across 
meson of path. 
No. 650. 
Stage [1]. —Greatest length, 22 mm.; width at base of anal segment, 
6 mm.; length in natural curved position, 10 mm.; thickness, 5 mm.; 
width of head, + mm.; length to apex of labrum, 3-75 mm. 
Cephalic margin of epicranial sclerite without sete. First antennal 
joint long and slender, not much shorter than second, this latter with 
one seta dorsad and three ventrad, the other joints naked. Mandibles 
about as in No. 377. Head smooth, shining, at the most very finely 
alutaceous. Pubescence about as in No. 45. Anal orifice V-shaped, the 
apex caudad and with a longitudinal median channel, running from apex 
to caudad of anal path. Peritremes and stigmata distinctly decreasing 
in size toward apical segments, the stigmata large, the peritremes 
much open. Apex of abdomen ventrad with a horseshoe-shaped area 
(open caudad) of about thirty stout, moderately long sete in one row, 
these sete much darker and larger than the seattered sete surrounding 
them, and set very close together. Whole body showing distinctly bluish, 
the yellow parts paler than in Lepidiota albohirta. 
Stage I1—Greatest length, 12 mm.; width, 3-5 mm.; length in 
natural curved position, 5-5 mm.; thickness, 3 mm.; width of head, 2-5 
mm.; length to apéx of labrum, 2-25 mm. Small species, resembling the 
smaller stages of the Lepidiota.
