8 The Cane Grubs of Australia. 
lacinia and galea apparently one stout piece with a longitudinal fold, 
with three stout black teeth at apex of lacinia, and one at apex of galea, 
this last the largest; this piece with setw of varying size; the stipes with 
sete around base of bulla and a few ventrad; galea attaining distal palpal 
point, the lacinia somewhat shorter. Maxillary palpus 4-jointed, the first 
joint (palpigerous stipes) short; second and third subequal, somewhat 
longer than wide, the fourth pointed-conical at apex, and fully two and 
a-half times as long as wide, the third ventrad with a single seta on each 
side distad. Mentum fleshy, a little wider than long, laterad and 
cephalad with long sete, these much shorter caudad, very short medially 
Labial palpus 2-jointed, the first joint a little wider than second, some- 
a wider than long, second over one-half longer than wide, the palpus 
naked. 
Stigmata circular, apparently closed; the peritremes circular, the 
thoracic pair larger than the abdominal ones, the thoracic pair irregularly 
circular, almost flat along caudal margin; abdominal peritremes closed 
except for a narrow slit in the centre of the rather flattened cephalic 
margin, this slit in centre of caudal margin of thoracic pair; a small oval 
spot in folds of last two thoracic segments. Thorax subquadrate, some- 
what wider than the head, prothorax dorsad without a transverse 
incision, the meso- and metathorax each with two deep incisions and thus 
with three dorsal lobes. Latero-cervical shield not much wider than 
greatest length (cephalo-caudad), its cephalic margin almost regularly 
gently, convex, its caudal margin forming the two sides of an obtuse 
angle, the side nearest venter much shorter than the other; without 
clothing except for long sete along the longer caudal margin and ventral 
third of cephalic margin. Cervix unarmed. Legs guarded cephalad 
and laterad by chitinised plates, these relatively smaller than in Lepidiota 
albohirta; legs only slightly increasing in size caudad, the hind femur 
not greatly larger than the cephalic one; tarsus of two posterior pair of 
legs as long as its femur, in the cephalic pair longer; spine on second 
tarsal joint shorter and stouter than in albohirta, its apex curved, other- 
wise the legs agree with those of albohirta. Abdomen cylindrical, some- 
what over thrice length of thorax, the last segment over twice the length 
of the others; incisions of segments as in albohirta, but the second lobe is 
smallest, longest at the meson. Clothing of reddish or ginger brown, 
epicranial sclerite without pubescence; on body, pubescence long and 
dense laterad and especially so on the segmental convexities. Dorsal 
aspect; Prothorax with rather dense, long pubescence, not arranged in 
regular rows; first lobe of mesothorax the same mesad, the second the 
same laterad, but without clothing mesad, the third with one irregular 
row continued its entire width; metathorax with clothing similar to meso- 
thorax; first lobe of first abdominal segment with dense, long pubescence, 
the second with one row mesad, dense laterad, also with a few very 
short stout hairs; lobes of remaining segments similar to second lobe ct 
first segment, except that there are more rows than one mesad, and the 
stout sete predominate on apical segments mesad so that on apical 
segments the pubescence is less dense and only scattered long sete are 
present, extreme apex of abdomen with dense long sete. Ventral aspect, 
segments of thorax and abdominal segments 1-8 with transverse (cephalo- 
caudad) areas of long sete, also first lobe of last segment, these much 
denser cephalad, rather sparse caudad; second lobe of anal segment with 
scattered set, the apex with rather dense, short, stout set followed at 
extreme apex by dense, long sete, no definite marked formation of set 
present.
