608 BRITISH OEIBATIDJI. 



progaster of the nympbal skin. The posterior end of 

 the old ventriculus is turned slightly upward. The 

 new colon has enlarged and is evidently attached either 

 to a new ventriculus below the old one or to the under 

 part of the old ventriculus itself. 



2nd. — The old ventriculus gets shorter and wider ; 

 the muscles to the new coxsd have become very con- 

 spicuous. 



4th. — The old ventriculus seems breaking up, par- 

 ticularly on the left side. 



6th. — The old ventriculus continues to break up ; its 

 cceca have become detached. 



7th. — The old alimentary canal has broken up alto- 

 gether. 



9th. — The adult has emerged ; it does not contain 

 any sign of the old highly-coloured alimentary canal 

 or appendages ; the new canal is very large but 

 entirely colourless. (This is not a question of the 

 contents of the canal but of local colour and external 

 coating of so-called liver-cells.) 



NOTASPIS LUCORUM. 



April 28th, 1887. — Placed a nymph which had just 

 become inert in a separate cell. 



30th. — No change as yet. 



May 1st. — The whole alimentary canal and internal 

 organs are travelling backward ; the skin of the rostrum 

 and legs appears empty. 



2nd. — No change to be seen. 



4th. — The clear sarcode appears somewhat striated 

 longitudinally. The alimentary canal, &c., have 

 travelled very far back. 



6th. — Thepseudo-stigmatic organs of the adult may 

 be plainly seen ; the canal, &c., are still very far back. 



7th. — The adult emerged ; apparently with the same 

 alimentary canal and its appendages as the nymph had 

 possessed, having the same high coloration and form, 

 and, as far as I could judge, absolutely identical.
