23 THE CANADIAN ENTOMOLOGIST. 



Myrmeleon formicarius, Linn. 



The curious habits of this insect are known for nearly two centuries 



and quoted so often that in my Synops. Hemerobidarum, p. 439, about 



half a page is filled by them. There is much written pro and con about 



this name. I believe the change of the name is simply a matter of taste, 



and I remember with merriness the page on which the late R. Crotch, 



my old friend McLachlan and myself were hacked to pieces for our 



heresy in nomenclature by A. Lewis. I consider the paper of McLachlan, 



Tr, Lond. Ent. Soc, 1871, p. 441, to be a very fair one. Of my two 



objections one has been removed by himself as I mentioned by M. 



formicalynx.
