 bij 2 dorsal shields. Anterior shield about A, posterior one about f 

 of body length. Anterior shield concave posteriorly ; posterior 

 shield concave anteriorly; so that between the shields there is a 

 horizontal spoolshaped unprotected part, which forms a pit, at the 

 bot lorn of it is attached the anterior bifid top of the penis apparatus. — 

 Anterior shield anteriorly with 2 fine hairs (fig. 27). A little before 

 the shoulders the ej/es between two hairs. Moreover 3 pair of hairs 

 arranged as shown in tlie figure. Fosierior dorsal shield with 

 6 pair of hairs or bristles, arranged like in the figure, and posteriorly

 transparency the whole penis appaiatus is visible. ^/«<* terminal. — 

 Stigma and peritremata like in the larva, discernable by transparency 

 through the anterior part of the abdomen. 



Tenis apparatus (fig. 34). The penis itself has a distinct gland 

 and is proximally trifurcate. In its distal half it is attached on a 

 quadrangular chitinous frame, which in its turn is attached to the 

 basal piece. The distal half of this piece is oval; the proximal half 

 bifurcate and attached at the dorsal skin in the bottom of the 

 dorsal pit between the two dorsal shields. 



Ventral side (fig. 26). Between coxae i one pair of hairs; 

 between coxae 3 one pair; between coxae 4 and the anus 4 pair; 

 a littie before the anus a pair, of minute rings with a point in 

 the centre. 



Mandibles (fig. 27, 30) like in the larva. 



Maxilae (fig. 26, 27, 30) hke in the larva. 



legs. Coxae (fig. 26) 1 and 2 contiguous ; coxae 3 and 4 con- 

 tiguous, close to coxae 2. Coxae 1, 2, 3 with 2, coxae 4 with 1 

 hair. Tarsi with a thick rod-like olfactoric hair in their proximal 

 half (fig. 28, 29). This hair is situated more proximally the more 

 you advances from leg 4 (fig. 28) to leg 4 (fig. 29).
