FXlll -grown larva. Length 30— 40mm. Head (Figure 33) oblong, mainly 

 yellow. Frontoclypeus with wide, straight, brownish black median stripe; 

 dots of transverse row in posterior part of sclerite visible only lateral 

 to stripe. Dorsal and lateral stripes brownish black, distinct, the former 

 from anterior margin to occipital foramen, where they almost meet near the 

 coronal suture; dots indistinct on dark background of stripes; dots usually 

 absent ventrally, pale when present. Lateral anterior -margin seta short, 

 light, curved inward; intermediate and median setae much longer, thin, 

 reddish yellow. Anterior -frontal setae light, curved inward; median frontal 

 setae long, near curves of frontal suture; posterior frontal setae slightly 

 longer, like the median setae, situated lateral to transverse row of dots. 

 Seta 9 long, dark brown at the base, slightly thickened; seta 11 short, thin, 

 light, situated behind seta 9; seta 7 situated ventral to antenna, like seta 10, 

 shorter than seta 9; seta 12 large, situated behind eye; setae 14 and 15 

 dark brown, situated one behind the other in the median -posterior direction 

 from seta 12 in light indentations near margin of dorsal stripe, the longest 

 on head; seta 16 shorter, situated lateral to 15; seta 17 long, situated 

 behind 16 near fork of epicranial suture. Ventral seta 8 brown, situated 

 some distance from anterior margin; seta 18 small, light, setuliform. 



Labrum (Figure 34) wide; dorsal sclerite brownish yellow; a whitish 

 tuberculate area behind the deep median depression which is situated 

 asymmetrically, slightly to the right. Seta 1 spiniform, light, small 

 (smaller than in Agrypnia); seta 4 large spiniform, situated further 

 posteriorly on each side near margin of median depression; seta 2 situated 

 anteriorly, smaller than 4; seta 5 thick, short, curved inward; seta 3 

 larger, straight, thin, brownish, situated laterally near the margin; seta 

 6 the largest on the sclerite, situated on the surface behind the median 

 depression. 



Apical tooth of right and left mandibles (Figure 35) displaced slightly 

 ventrally; dorsal blade of left mandible with 3 teeth, a large basal, and 

 small intermediate teeth; ventral blade with 2 teeth, basal tooth large. 

 Dorsal and ventral blades of right mandible with 2 teeth each: one small, 

 the other basal, large, triangular. Outer setae brown; apical -dorsal 

 seta shorter and thinner than the basoventral seta. 



Maxillolabiiom (Figure 36). Mentum indistinct, whitish, both setae large, 

 brown, situated on dark sclerotized dots; sclerites of cardo dark, seta 

 small; stipes yellowish brown, both setae situated on the membrane, 

 apical seta near sclerite, basal seta at a distance, both on sclerotized 

 dots, brown. Palpifer and distal seta dark brown; sclerites of palp 

 oo segments and galea the same. Mentum short, semicircular, shining 

 blackish brown; rodlike ventral sclerites and sickle -shaped sclerites 

 of palpiger thin, blackish, former with light seta.
