Full-grown larva. Length 8— 10 mm; sclerites yellowish; pattern grayish 

 or reddish brown; setae thin, weak, brown, brownish yellow or light. Head 

 markedly longer than broad, with almost parallel sides; light periocular 

 field large; antennae with one relatively long seta and 2 short setae. 

 Frontoclypeus with straight anterior margin, brownish, dark brown 

 posteriorly, with a transverse row of 4 or 5 light dots. Dorsal stripes 

 short, brown, with large light and dark dots; a narrow light space between the 

 dorsal stripes and the epicranial suture; isolated dots instead of the lateral 

 stripes; Anterior -margin setae long, thin, displaced to the anterior angles; 

 lateral seta lighter than the others, slightly curved inward; anterior frontal 

 seta short, transparent, recumbent; middle seta situated in the anterior part 

 of the sclerite, posterior seta in its broad part; both setae long, thin and 

 brown; the light spots at the base of these setae are the lateral dots of the 

 transverse row. Seta 7 moderately long, situated near the anterior margin; 

 seta 9 situated medial to the eye, long and brown, the small light setae 11 

 situated near it; the small, light seta 10 situated lateral to the eye; the thin, 

 long, brown setae 12 and 14 and the small light seta 13 situated posterior 

 to the eye; setae 15 and 16 small, situated near seta 13; seta 17 situated 

 near the bifurcation of the frontal sutures, small, spinelike, yellowish and 

 curved posteriorly. A narrow dark stripe ventrally, along the gular suture; 

 middle of head with a light and a dark dot; indistinct light dots near the 

 occipital foramen; seta 8 situated near the anterior margin, small and spine - 

 like. 



Anteclypeus oblong, tapering anteriorly, light; its broad longitudinal 

 stripes indistinct and pale. 



Labrum (Figure 545) small and short, with rounded anterior angles; 

 anterior part of dorsal sclerite indented in the middle, brownish yellow, 

 brown posteriorly, dark with brown spots near the posterior angles; 

 posterior -angle sclerites rodlike, dark and slightly curved; median 

 depression of the membranous anterior margin shallow, with short straight 

 hairs; sides of anterior margin and sides of labrum with longer hairs. 

 Seta 1 small, transparent, situated among the hairs; setae 4 spinelike, 

 situated at the margin of median indentation; setae 6 situated posterior to 

 them; setae 2, 3 and 5 relatively thick and light brown, situated at the sides 

 of the sclerite.* 



Mandibles long, massive, more than half as long as head; apical tooth 

 broad, bluntly rounded. Left mandible with a deep median indentation; 

 upper blade of left mandible with 2, sometimes 3 teeth near the distal 

 margin; two tubercles in the middle; lower blade with 2 teeth; chetoids of 

 penicillus in the median depression of varying length; the mandibles have a 

 small groove on the outer side near the base; outer setae situated in about 



* The cover of dense short hairs shown by Hickin (1950:67, Figure 5) is absent on the dorsal surface of the 

 labrum; Morton (1890a, Figure 7),Klapalek (1893, Figure 1) and Siltala (1905) also do not show these hairs 

 for species of Tinodes.
