Larva. Length 520 i^. Colour white. Shape broad- 

 oval, top backward, slightly truncate. T e x t u r e. On the 

 dorsum (Fig. 8) there were a few wrinkles, imitating scales, 

 or scales simulating wrinkles ; this I could not decide, even 

 not with immersion. One unbroken wrinkle surrounded a space 

 which exactly looks like an anterior dorsal shield, 

 or, as we have before us a larva, which reijresents primitive 

 forms, a shield which we may safely compare with the 

 dorsal shield of the p r o s o m a of Scorpions. 

 Moreover I did not observe any true scales or tine wrinkles. 



Dorsal side (Fig. 8j protected by an extremely thin 

 dorsal shield (see above) on which are planted 9 pair of 

 bristles on the usual places ; one of these pairs, a little behind 

 the implantation of legs Hi, is as long as the half of the 

 creature's greatest breadth. Behind the dorsal shield, on the 

 metasoma, 5 pair of bristles, of which the pair in the centre 

 is slightly stronger than the other ones ; before this pair a 

 pair of pores. 



Ventral side. T r i t o s t e r n u m (Fig. 12) long ; 

 halfway not only provided with minute spines on the edges, 

 but also as far as I could observe (with immersion !) on the 

 side turned towards the observer (ventral side). There are 4 

 tìagellae placed in pairs which leave a considerable distance 

 between each other ; here you observe a little bitid piece. The 

 inner flagellae are twice longer than the outer ones, and fea- 

 thered ; the outer ones are smootli and distally bitid. —
