the shield. On the posterior edge of the posterior shield 2 

 pairs of hairs slightly longer than the greatest width of the 

 body. Minute hairs are to be found : on the anterior shield 

 one pair inward of the long ones, on the lateral shields one 

 pair near the anterior edge; on the posterior shield one pair 

 near the anterior edge, one pair on the dorsum in a line with 

 trochanteres III ; one pair more lateral on a line with trochan- 

 teres IV; one pair inward of the excretory glands; and one 

 pair behind these glands. The openings of the ex- 

 cretory glands on a line with femora IV. 



Ventral side (Fig. 4). Epimera I free ; epiraera 11 some- 

 what bent outward; behind trochanteres II the chitinous 

 ventral prolongation of the dorsal dark margin of the anterior 

 part of the body; epimera III rather short and nearly touch- 

 ing the above mentioned chitinizatiou ; epimera IV with 

 proximal short epimerite and distal external one of which the 

 first part is a square. Epigynium crescent-shaped nearly semi- 

 circular ; its foremost edge on a line which goes between the 

 lateral chitinous bars and the epimera III. Valves of vulva 

 with somewhat chitinized borders. Minute hairs: one pair 

 between epiraera I and II, one pair outside of epimera III; 

 (the long hair which should be implanted here has become 

 dorsal) ; one pair before epimera IV ; one pair between the 

 chitinous valval borders and the epimera IV ; one pair inside 

 of epimera IV; and one pair near the oblique edges posteriorly. 

 Outside of epimera I and II and inside of epimera III and IV 

 and of the lateral chitinous bar are narrow rudiments of 

 coxal plates. 



M a n d i b u I a seen from above, like in the nympha. 



Maxillae like in the nympha.
