cylindrical, the secone segment flattened, shaped somewhat like a door knob; a few sensory 
projections. Mandible (Plate XXV, 87 and 88) powerful, produced into a strong apical 
point, with about four or five blunt or irregular inner. teeth anda strong dorsal tooth on 
outer margin before tip. Maxilla (Plate X XV, 87) large, the outer margin thickened, sub- 
chitinized; palpi at apex small, shaped like half a pill box, with a few sensory papillae 
at tip. 
Pupa.— Length, 18-20 mm. 
Width, d—s., 2.8-3 mm. 
Depth, d—-v., 3.1-3.3 mm. 
Entire head and thorax, including leg and wing sheaths, light brown, the thoracic dorsum 
somewhat darker-colored, the wings more yellowish brown; abdomen pale light green, the 
segments with the submedian brown band interrupted on pleural region; tip of abdomen 
brownish, chitinized. 
Form stout (Plate XXV, 89); body destitute of noticeabie setae. 
Head flattened (Plate XXTV, 84). Cephalic crest lacking; forehead with a shallow V-shaped 
notch between antennal bases. Eyes of male large, the front narrowed, with points of 
tentorium close to inner margin of eye; eyes of female more widely separated. Antenna 
rather short, ending just beyond wing root. Labrum short, obtuse. Labial lobes contigu- 
ous, divergent, blunt at their tips, posterior margin a little convex medially. Lobes of 
maxillary palpi large, subquadrate. Cheek with a large, flattened ledge overlying joint of 
fore legs. . 
Thorax very gibbous. A distinct anterior median carina between breathing horns. 
Pronotal breathing horns (Plate X XV, 90) flattened, earlike, broader than long, directed 
slightly proximad, margin with a row of breathing tubercles, outer face wrinkled. Wing 
sheaths reaching base of third abdominal segment. Leg sheaths reaching base of fourth 
abdominal segment or a little longer; tarsi ending about on a level, or sloping gradually from 
short hind tarsi to long fore tarsi. 
Abdominal segments indistinctly subdivided into three rings; on tergites 3 to 7, and 
sternites 5 to 7, basal ring with a transverse welt which is densely covered with short hairs 
or hooks, these welts tapering gradually to ends; sternites of segments 3 and 4 having incom- 
plete welts on either side of leg sheaths; band on tergum of segment 7 not broken medially, 
but a little constricted in some specimens; in older pupae the other annuli, especially the 
posterior one, variously darkened on dorsum and venter. Female cauda (Plate XXIV, 85) 
with the acidothecae short, the sternal valves the shortest, the tergal valves a little longer; 
prominent lateral lobes at base of tergal valves, and a slightly smaller but very broad one 
on each side of tergal valves at about midlength. Male cauda (Plate XXV, 91) similar to 
that of female, but the dorsal lobes (Plate X XV, 92) much shorter, not longer than the ven- 
tral lobes, and separated by a U-shaped notch; ventral lobes approximated, each ending 
in a small, blunt tubercle. Two small circular spiracles on dorsum of segment 8, these a 
little more widely separated in male than in female.
