cylindrical, the secona 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 and a strong dorsal tooth on 

 outer margin before tip. Maxilla (Plate XXV, 87) large, the outer margin thickened, sub- 

 chitinized; palpi at apex small, shaped Uke 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 noticeable setae. 



Head fattened (Plate XXIV, 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 XXV, 90) flattened, earlike, broader than long, directed 

 slightly proximad, margin with a row of breathing tubercles, outer face wi'inkled. 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 foie 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 XXV, 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.
