No: 71: 
Stage I1I.—Greatest length when extended, 44 mm.; width at 
base of anal segment, 14 mm.; length in natural curved aati 24 mm.; 
thickness, 11 mm.; width of head, 5 mm.; length to apex of labrum, 5 mm. 
Similar in many respects to Dasygnathus. Second lobe of anal 
segment dorsad with most of its surface raised and bounded by an oval 
suture. Head with smali seattered punctures; epicranial sclerite with 
a row of set near its cephalic margin and with long sete scattered 
over its surface, also the epicranium; clypeus with two sete on either 
side of meson and two far laterad. Antennal joints not slender, the second 
longest, not twice as long as wide, a little longer than the third, the 
first distinctly shorter ; second joint with two sete dorsad, the rest naked. 
Mandibles without the second apical tooth, the small tooth just laterad of 
the retinaculum present, barely indicated in right mandible. Peritremes 
distincly open. lLatero-cervical shield somewhat wider than greatest 
length (cephalo-caudad), its cephalic margin strongly convex, the two 
eaudal sides of about equal length and with about five sete along its 
dorso-caudal margin. Pubesecence rather sparse but denser than in 
Dasygnathus, the apex of abdomen ventrad with close stout sete. 
No. 349. 
Stage III.—Greatest length when extended, 35 mm.; width at 
thorax, 8-5 mm.; length in natural curved position, 14 mm.; thickness, 
7-5 mm.; width of head, 6-10 mm.; length to apex of labrum, 6 mm. 
Body widest at the thorax, slightly tapering toward apex of abdo- 
men. Middle pair of legs somewhat longer than either first or third. 
Peritremes flattened, very open, both thoracic and abdominal ones open 
along cephalic margin, the abdominal. ones greatly decreasing in size 
caudad, very small on segments 6-8. Epicranium practically smooth, 
Cae with a very few ‘scattered pin-punctures and a very few seat- 
tered sete ; cephalic margin of epicranial sclerite with one seta on either 
side of meson, also a small oval fovea against either lateral margin in 
centre (caudo- cooualae ; elypeus with a few scattered sete; labrum as 
usual. Outer side of mandible quite straight, not at all curved; left 
mandible with five acute teeth, the proximal ones smallest, the retina- 
culum consisting of ene outer tooth and one long obtuse proximal one, 
the penicellus absent; right mandible with four teeth, less acute, the 
retinaculum 4-dentate, the basal tooth obtuse, the outer three acute. 
Lacinia and galea distinctly separated, each with a stout curved spine 
at apex, the galea a little longer than lacinia. Maxillary and labial palpi 
about as usual, the third joint of former with one seta at base and one 
at apex dorsad. Lobes of thoracie and abdominal segments, especially 
the latter, not well defined. Thorax, apical abdominal segments and all 
body ventrad with scattered setx ; abdominal segments 1-6, dorsad, with 
very dense minute teeth or sete. Anal orifice consisting of a deep:
