compavison of Mr. Hanham's list of butterflies, containing thirty-nine 

 species, with one published by the late Mr. Billings (Can. Ent. Vol. I) 

 in 1868, and which contains the same number of species, shows that 

 there are nine species in each which are not in the other, which with two 

 additional species known in other collections will make a total of fifty 

 species so far recorded from this locality. It was at first proposed to 

 publish as an appendix a list of butterflies, but by deferring it for another 

 year it will probably be made more complete. Among Mr. Hanham's 

 butterflies is Pieris rajyce, the cabbage-butterfly, now the most common 

 of all our species, but which has been introduced since the date of the 

 older list. This fact shows the importance of publishing local lists, 

 which are not only valuable as records of the species then known, but 

 for comparison in after years by ]:iersons studying the changes which are 

 ever taking place in fauna and flora. Among Mr. Hanham's butterflies 

 was a Thecla (taken near Hull on 21st May) a drawing of which was 

 sent to Mr. W. H. Edvvards, who writes that it is probably Thecla nlphon, 

 a rare species, of which he has only taken two specimens. Specimens 

 of Eudryas grata, the Beautiful Woodnymph, were received on July 

 10th, from Mr. Geo. Hay, with a statement that they were very 

 numerous on his grape-vines. Lady Ritchie also sent a pair which were 

 taken in the Chief Justice's garden. This moth was unusually abundant 

 last season, but, although the larvaj feed upon the grape^ we did not hear 

 any complaints from fruit-growers of trouble with it, but it was reported 

 as disfiguring the Virginia creeper in some places. The red-humped 

 caterpillars oi JVotodonta concinna were reported on apple trees near the 

 city. They are voracious feeders, stripping branches, and sometimes 

 small trees, very rapidly, but are easily detected and destroyed and need 

 not be much feared. The number of butterflies and moths already 

 captured here indicates that this is a rich field for the lepidopterist, and 

 when properly worked and sugared it will undoubtedly yield a rich and 

 varied harvest. 



DiPTERA. — This order of tv/o- winged flies contains our most 

 pugnacious and aggressive insects. They not only valiantly, and often 

 successfully, defend their native glades and meadows, but also swarm 

 forth to make war upon us in our houses. Yet so little is known about 

 them that we are in doubt eyen as to the title or titles of our mosquitoes.
