black spot and spot absent. Setae of meso- and metathorax, like the 

 abdominal setae, especially the anterior-angle setae, long; setae of the 

 laterodorsal sclerite of anal legs long. 



Second stage (?). Length 10.5—12.5 mm. Head markedly oblong, as 

 broad as the abdominal segments; head and prothorax together about /a as 

 long as the body. Head sutures and suture of pronotum marked. Pattern 

 distinct on the background of the shining brownish yellow sclerites (as in 

 the full-grown larva); median stripe of frontoclypeus present; dots, spots 

 and stripes indistinct. Setae relatively long. Laterodorsal sclerite of anal 

 legs with only one laterodistal seta in addition to the 2 dorsal setae and the 

 ventral seta.

 ventral (prepupa visible inside) (A) and dorsal (B) 



Pupa. Length of young pupa 25— 26 mm (Figure 533). Antennae long, their 

 ends coiled around the posterior segments; 1st antennal segment large, its 

 setae short and black. Setae of anteclypeus (Figure 534) stituated on small 

 brownish sclerites, 3 on each side; lateral seta yellowish, almost transparent, 

 shorter than the other two reddish brown setae; the intermediate seta 

 slightly longer than the median seta. Labrum as in Philopotamidae, with 

 3 reddish brown setae at each side of the anterior margin; intermediate seta 

 lighter and median seta longer and thicker than the others. Mandibles long, 

 geniculate, without teeth, with straight, coarsely serrated blade and dark, 

 pointed apex; outer setae present at the base; basal seta straight and dark, 

 reddish brown; a shorter, spinelike transparent seta slightly anterior to it.
