 " Further Notes on the Jurinian Genera of Hymenoptera," by the Rev. 

 F. D. Morice and John Hartley Durrant, is well worth consulting for 

 the remarks on " emendations " in the spelling of names, and as one of 

 the authors is an eminent classical scholar, the severe condemnation of 

 such " misapplication of learning" should carry some weight. 



The Can'idian Ent. for May, among other matters, contains (1) 

 " Notes on the Black Apple Leaf-hopper {Idiocerus litchi) " ; (2) An 

 account of the " Collections of the Entomological Society of Ontario " ; 

 (3) A discussion on " Seasonal Irregularities in the Occurrence of 

 Dragonflies," by E. M. Walker, which concludes with the following 

 pomts, (a) Certain species of dragonflies are much more abundant in 

 certain localities during warm seasons than during cold seasons, (b) 

 The abundance is probably not due to the emergence of large numbers 

 of individuals from their breeding-places, but to the greater activity of 

 flight in warm weather, whereby the insects are dispersed to localities 

 not visited in cooler seasons, and (c) The Odonate fauna of a restricted 

 locality contains a large percentage of transient resident species and 

 stragglers from other localities, such species varying greatly from year 

 to year ; and (4) " An Interesting Case of Instinct," of which the 

 following paragraph is a summary.
