Changes and improvements have been made in the collection 

 of Lepidoptera and in the Biological Collection. The Odonata 

 are now ready, and alone fill a whole cabinet. The new speci- 

 mens of the other orders are now in the right place. 



The following papers from this department have been pub- 

 lished during the last year : — 



Louis Cabot. The Immature State of the Odonata, Part III. Sub- 

 family Cordulina. Memoirs of the Museum of Comparative Zoology, Vol. 

 XVII., No. 1, with Six Plates. Of the next part, four plates are ready 

 for next year, finishing the Libellulina. Only one part more, containing 

 all the Agrionina, is to follow, to finish the large and very important work 

 on the immature state of the Odonata contained in the collection of the 

 Museum.
