Abdomen. Setae on tergites forming anterior and median rows, 

 though separation sometimes not distinct on posterior tergites. Anterior 

 row consisting of about 2-4 setae. Genitalia as shown in Fig. 2. Gono- 

 coxite IX with 3-4 larger, and about 3-5 smaller setae. Tergite IX, Fig. 3, 

 without indication of caudal emargination. Cerci 57-66 (6) long. Notum 

 with a light triangular area at junction of rami. Ducts of seminal cap- 

 sules much narrower in anterior length than in posterior length. 

 Pupa.— N = 6. 



Cephalothorax. Pale brown. Thorax with much of dorsal surface 

 reticulate and faintly rugose. Thoracic horn (Fig. 5) elongate with 

 rounded apex, entire surface smooth, 74-157 (10) long, 10-20 (7) wide. 

 Median antepronotals 2; precorneals 3, with Pc2 longest and most 

 robust, and PC3 shortest and least robust. Dorsocentrals consisting of 2 

 pair with Dei and DC2 widely separated from each other. Frontal apo- 

 tome slightly to moderately wrinkled; FS on prefrons up to 57 long. 



Abdomen. Pale brown. Chaetotaxy and other details as shown in Fig. 

 4. T I-VII without shagreen. T VIII-IX with shagreen, most pronounced 

 on T IX, and very sparse on VIII. T II-VI with median and caudal 

 bands of spines and spinules; a few spines bifid or trifid. Median band 

 of spines and spinules on T II not extended as far laterally as other 

 bands, and may appear interrupted medially. T VII-VIII with caudal 

 spines and spinules only. Spines on T VI and VII longest, with some up 

 to 23 long. Conjunctives of T II-VI with several rows of recurved spin- 

 ules. Sternites II-VIII with faint, uniformly distributed shagreen. S VI- 

 VII with a few caudal spinules. Pedes spurii A on S IV-VII, most pro- 

 nounced on S VI. Segment I with 2 non-filamentous L setae, segments 

 II-VI with 3 non-filamentous setae, segment VII with 3 filamentous L 

 setae, segment VIII usually with 4 filamentous L setae. Many D, V, and 

 non-filamentous L setae appearing bifid. Dorsal O setae on T II-VII. 

 Anal lobe with about 2-4 small apical spines and 3 curved macrosetae of 

 about equal length. Fringe of anal lobe with about 7-12(12) setae. 

 Larva. — N = 9; final instar. 



Head. Yellowish brown with dark brown mandibles and mentum. 

 Antenna as shown in Fig. 6. Lengths of antennal segments 1-5; 40-46 

 (12), 17-20 (12), 7 (12), 6 (12), 4 (12); A.R. of 1.08-1.35 (4). Basal seg- 

 ment 17 (11) wide; ring organ at base; blade extended to middle of 

 fourth segment; accessory blade not visible; lauterborn organs about 6 

 (6) long. Premandible (Fig. 7) simple, with mesal spiny projection. S I 

 appearing simple in most specimens, apex at most with one weak serra- 

 tion. Maxilla as shown in Fig. 8. Mandible (Fig. 9) 94-103 (8) long; seta 

 interna with several branches. Mentum (Fig. 10) with slightly peaked, 

 but generally rounded median tooth 19-20 (4) wide; median tooth some- 

 times weakly notched on each side; fifth lateral tooth small. Ventromen- 

 tal plates about 2-3 (8) wide. Width of ventromental plate/ width of 

 median tooth 0.10-0.16. Postmentum 126-134 (8) long.
