Larvae. Co/o2^r vermillion. — Length of body 52.5; ofbody pseu- 

 docapitulum and rostrum 700 ^< — Borsai side (Fig. 31). It 

 seems to me that the whole skin is soft. No dorsal shield is visible 

 and no crista. The space, which should be occupied by a dorsal 

 shield, bears 2 pairs of very fine sensorial hairs and 2 pairs of 

 stronger feathered hairs. — The two eyes are prominent, far 

 remote, situated in the foremost fourth part of the body, a space 

 almost destitute of hairs, comparable with the thorax of the adult. 

 They are on a level behind the two hindmost sensorial hairs and 

 before the coxae 2. — Next to each eye there is a hair inward. 

 The real abdomen is hairy, without any indication of segmentation. 

 The hairs stand in transversal and longitudinal rows , but irregularly. 

 Only the foremost transversal row and the two most central lon- 

 gitudinal rows are distinct. 



Ventral f ace (Fig. 32). — The coxae are not contiguous. The 

 coxae 2 and 3 bear distally and forward a spine, and on their 

 ventral side a hair. On the inner side of coxae 1 and 2 you 

 observe a hair. In the hind half of the space between the coxae 



2 and 3 there are 14 hairs ranged in 7 pairs; between the coxae 



3 one pair, and behind the coxae 3 on the belly 3 pairs. The hinder 

 part of the belly is also somewhat hairy, like the dorsum. —
