of mandible. Maxilla rather small, simple; palpus large, antenniform, with apex bluntly 
rounded; inner lobe densely covered with short, stout setae surrounding a powerful bristle 
and a small brown sensory organ. 
Pupa.— Length, 30-33 mm. 
Width, d.-s., 5-6 mm. 
Depth, d.-v., 5.56 mm. 
Coloration pale yellow; pronotal breathing horns liver-colored. (In older specimens 
the thorax and appendages are dark-colored, and the abdomen has broad brown sublateral 
stripes.) 
Head rather small, cephalic crest lacking. Antenna stout, rather elongate, extending far 
beyond ends o palpi, segments angulated. Clypeus and labrum tumid, transversely wrinkled. 
Labial lobes slender, divergent. Sheaths of maxillary palpi rather slender, tips curved 
but not recurved (Plate LX XXVIII, 485). Pronotal breathing horn (Plate LXXXVIII, 
486) large, broadly flattened, slightly incurved, broader at apex than at base, deeply furrowed 
up middle of outer face, the broad margin thus formed deeply wrinkled to erenulate. 
Mesonotum large, transversely wrinkled, with two blunt tubercles provided with short setae 
(Plate LX XXVIII, 484). Wing sheaths small, reaching end of second abdominal segment. 
Leg sheaths ending before tip of third abdominal segment; fore tarsi very short, hind 
tarsi the longest, those of middle legs intermediate. 
First abdominal tergite with two spines; segments 2 to 7 broad, divided into the usual basal 
and posterior rings; second segment on posterior ring with four spines; segments 3 to 6 with 
six to ten spines, the intermediate ones usually smaller; segment 7 with four spines; pleurites 
with a spine on each ring; sternites with similar arrangement to that of tergites, but spines 
usually fewer in number, segments 3 and 4 with only a single widely separated spine on each 
side, segments 5 and 6 with four or five sp:nes, segment 7 with three spines; segment 8 has 
four small spines between the large lateral ones described below. Male cauda blunt, dorsal 
lobes very divergent, ending in sharp, chitinized points. Female cauda (Plate LX XXVIII, 
487) with tergal valves elongate, narrowed to the moderately acute tips; sternal valves 
similar in shape but smaller; lateral lobes of ninth segment directed caudad and laterad, 
at tips running out into chitinized points; two small setae before tips; segment 8 with a 
powerful lateral lobe on either side, each terminating in a chitinized point; posterior lat- 
eral angles of segment produced into slender, blunt points.
