Hypermetamorphosis 



circular disk deeply wrinkled at the centre. 

 The three segments that come after the head 

 bear each a pair of very minute knobs, hardly 

 visible without the lens : these are, to the legs 

 of the larva in its previous form, what the 

 cephalic mask is to the head of the same 

 larva. They are not organs, but indications, 

 landmarks placed at the points where these 

 organs will appear later. On either side we 

 count nine stigmata, set as before on the 

 mesothorax and the first eight abdominal 

 segments. The first eight breathing-holes 

 are dark brown and stand out plainly against 

 the yellow colour of the body. They consist 

 of small, shiny, conical knobs, perforated at 

 the top with a round hole. The ninth 

 stigma, though fashioned like the others, is 

 ever so much smaller; it cannot be distin- 

 guished without the lens. 



The anomaly, already so manifest in the 

 change from the first form to the second, 

 becomes even more so here; and we do not 

 know what name to give to an organism 

 without a standard of comparison, not only 

 in the order of Beetles, but in the whole class 

 of insects. While, on the one hand, this 

 organism offers many points of resemblance 

 to the pupae of the Flies in its horny con- 

 sistency, in the complete immobility of its
