Hypermetamorphosis 



port assumed that, instead of remaining in 

 the same Anthophora-cell, the larva, which 

 is capable of burrowing, passes from one cell 

 to another in search of additional nourish- 

 ment. This suspicion seems to me to be 

 well-founded, for the size which the larva 

 finally attains exceeds the proportions which 

 the small quantity of honey enclosed in a sin- 

 gle cell would lead us to expect. 



Let us go back to the pseudochrysalis. 

 It is, as in the Sitares, an inert body, of a 

 horny consistency, amber-coloured and 

 divided into thirteen segments, including the 

 head. Its length is 20 millimetres. 1 It is 

 slightly curved into an arc, highly convex on 

 the dorsal surface, almost flat on the ventral 

 surface and edged with a projecting fillet 

 which marks the division between the two. 

 The head is only a sort of mask on which 

 certain features are vaguely carved in still 

 relief, corresponding with the future parts of 

 the head. On the thoracic segments are 

 three pairs of tubercles, corresponding with 

 the legs of the recent larva and the future 

 insect. Lastly, there are nine pairs of stig- 

 mata, one pair on the mesothorax and the 

 eight following pairs on the first eight seg- 

 ments of the abdomen. The last pair is 



1 .787 inch. Translator's Note.
