skin consisting of fine transparent pellicle, 

 without any rent whatever. This is the 

 pouch of the Sitaris, save that it lies in imme-

 this jacket we distinguish three pairs of tiny 

 legs, reduced to short vestiges, to stumps. 

 The head is in place, showing quite percep- 

 tibly the fine mandibles and the other parts of 

 the mouth. There is no trace of eyes. Each 

 side has a white edging of shrivelled tracheae, 

 running from one stigmatic orifice to an- 

 other. 



Next comes the pseudochrysalis, horny, 

 currant-red, cylindrical, cone-shaped at both 

 ends, slightly convex on the dorsal surface 

 and concave on the ventral surface. It is 

 covered with delicate, prominent spots, 

 sprinkled very close together; it takes a lens 

 to show them. It is i centimetre long and 

 4 millimetres wide.^ We can distinguish a 

 large knob of a head, on which the mouth is 

 vaguely outlined; three pairs of little shiny 

 brown specks, which are the hardly per- 

 ceptible vestiges of the legs; and on each 

 side a row of eight black specks, which are the

 the first by an empty space, form a continu-
