of mandible. IMaxilla 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., 5.5 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 LXXXVIII, 485). Pronotal breathing horn (Plate LXXXVIH, 



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 crenulate. 

 JMesonotum large, transversely wrinkled, with two blunt tubercles provided with short setae 

 (Plate LXXXVin, 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 

 s.de, segments 5 and 6 with four or five spines, 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 LXXXVIII, 



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.
