SOME INMATES OF A DECAYED CHERRY-TREE. 285 



could not be given to the solution of fuitlier points in the life- 

 histories of certain species, of which I could find no reliable 

 account in the literature I possess. 



For the kind identification of doubtful species I am indebted 

 to the following authorities, whose valued aid enabled me to draw 

 up the appended list : — Mr. Edward Saunders kindly examined 

 the Hymenoptera-Aculeata ; Mr. T. E. Billups, the Parasitic 

 Hymenoptera, &c. ; Dr. Meade, the Diptera ; Mr. H. C. A. Vine, 

 the Aphidida;. 



The list is not exhaustive, and several additions to the fauna 

 of our stump could have been made had time permitted the 

 examination of observed examples of Crustaceans, Myriapods, 

 and Araclmoidea.
