Labrum (Figure 118) rounded anteriorly, with a small, sometimes 

 indistinct, median process; anterior-margin seta small, situated laceral 

 to median process; other 5 setae long, hooked; 3 setae of anteclypeus 

 markedly shorter and thinner. 



Mandibles (Figure 119) long, basal part separated by a fold; blade 

 straight, serrated, dorsal seta larger than ventral.

Wing sheaths reaching abdominal segment 6 in male pupae, shorter 

 in female pupae. Dorsal process of abdominal segment 1 brown apically, saddle - 

 shaped. Lateral line on segments 4—8, with small, light setae anteriorly, 

 from end of segment -5 with dense, long chestnut brown setae, near median 

 line on ventral side of segment 8 of female pupae, reaching to the base 

 of the genital appendages in male pupae. Holding apparatus on segments 

 3—7 in form of brown plates with large black hooks; presegmental plates 

 small, postsegmental plates transverse; number of hooks: 111:2—3; 

 IV: 3—2; V: 3 +9—13; VI: 3; VII: 3—4. Four setae at the base of each anal 

 rod. Anal rods short, straight, brown, finely tuberculate, with 3 small, 

 thick, asymmetri.cally situated setae at the median margin, apically and 

 subapically, with 2 small, curved, reddish brown setae (Figure 120). 



Ventral genital appendages of male pupae long, projecting almost 

 to end of short, thin anal rods (Figure 120). 



Pupal case 23— 24 mm long, made of coarse sand grains, rounded 

 posteriorly, attached to the substrate at its anterior end by lateral strands
