RURALIS BETUL*;. 



Portion of cremastral area of pupa x 100. 



Shows irregular fracture, due to flattening for photographic purposes. Less 

 than half the area broken away. It exhibits : — 



1. The dorsal portion of the 10th abdominal segment with a pale (less chitinisedj 

 band, and a darker terminal portion on both these. 



2. The cremastral hooks (?) reduced to very short blunt hairs. 



3. The origin of these hairs at the intersections of the fine ribbings of the 

 skin-sculpture. 



4. A large lenticle in the middle of the dark area ; also one in the pale area 

 (to left of lower part of the dark area) ; also two on the ventral area (to right) . 

 [Note that these are all repeated on the opposite side, but are not symmetrical, i.e., 

 they are near the same place on the other side, so near as to appear to correspond, 

 but are sufficiently distant to make it possible that they do not.] 



5. Fine skin-spiculse, seen down on the right, i.e., above or dorsal to the 

 pale band. 



6. The ribbing of the skin-sculpture, and the points they carry.
