Father Leopold: Is it a fact that there is no male on cherry? 



Mr. Boss: The male is produced only on the secondary host. 



Dr. Headlee : We found with apple aphis that there was a peculiarly suscep- 

 tible stage in the egg just before hatching. The Qgg has three layers, one of 

 which is a transparent layer, and this layer splits about a week before hatching. 

 The egg is then very susceptible to light, moisture and other influences, and to 

 chemical sprays, etc., and I wonder if Mr. Eoss has found a similar condition 

 in the eggs of the Black Cherry Aphis? 



Mr. Eoss: No. I have not found this with Black Cherry Aphis, but I have 

 with Apple Aphids. We fumigated trees that were heavily stocked with the eggs 

 of the Oat Aphis and Aphis pomi about ten days before the buds burst. We 

 destroyed one hundred per cent, of the eggs with hydrocyanic acid gas, 1 oz. to 

 100 cubic feet, but we have not done anything with the Cherry Aphis. 



Dr. Headlee: Have you experimented with chemicals on the eggs? 



Mr. Eoss : No. 



Dr. Headlee: We found that carbolic acid was effective in dealing with 

 the apple aphis egg at this stage. 



Prof. Caesar: Was this a laboratory experiment or an orchard experiment? 



Dr. Headlee: Both. 



Prof. Caesar: Dr. Headlee gives us another suggestion, and that is what most 

 workers are seeking for. From my own observations it would appear that lime- 

 sulphur wash seems to have quite an effect during some seasons, and in other 

 seasons it has almost no effect, or a very slight effect. 



Dr. Headlee: The addition of Black Leaf 40 seems to increase the killing 

 effect of lime-Bulphur on the egg. I think Parrott and Hodgkiss had some success 

 with this. 



A COMEDY OF EEEOES. 



Francis J. A. Morris, Peterborough. 



It is surely astonishing how often the two Dromios have made their appear- 

 ail'ee on the entomological stage. These amusing little comedians seem never to 

 pall, and their simple farce, trite as it is, continues — like a Punch and Judy show, 

 or the Marks Bros. — to draw crowded houses and evoke peals of delighted applause. 

 It speaks well for the wholesomeness of our hobby that the entire brotherhood of us 

 should remain so perennially gullible, so good-humoured over mistakes, and so easy 

 of diversion. IMasquerading must be as old as the hills, and mistaken identity 

 forms one of the leading motives in the world's literature. It is found in the 

 oldest sagas. Aristotle remarks how effectively TTonier uses it in the Odyssey; 

 and still to this day it remains one of the great well-springs of Eomance, now 

 sparkling in the lightest of comedies, now darkening the unplumbed gulfs of tragic 

 depth.
