SUGGESTED CORRECTIONS. 



I am very grateful to receive suggestions correcting, explaining or differing 

 from anything contained in The Butterfly Farmer. Correspondents will feel 

 free to criticize,, or in any manner assist in the work we are trying to do. We 

 have received the following: 



John F. Weigand, 1002 6th Ave., So., Wausau, Wis., writes: 

 "I would like to make what I believe to be a slight correction in your 

 chapter on 'How to tell live pupae.' If parasites are present, there will be 

 no sound in the cocoon when shaken as the small parasitic cocoons are fastened 

 to the wall of the other. When the caterpillar has died of the peculiar disease 

 prevalent among so many varieties, the empty skin will rattle around inside like 

 fine shot. You have just reversed the matter, but it is only of minor im- 

 portance." 



William Reiff, 366 Arborway, Jamaica Plain, Mass., says: 

 "At a proper occasion you will perhaps correct the point regarding open- 

 ing of silken cocoons as published on page 63 of The Butterfly Farmer. It is 

 never of disadvantage for the pupa to be cut open in any kind of cocoons of 

 Lepidoptera, as long as proper care is taken concerning heat, moisture, etc. If 

 a cocoon cut open does not give rise to a perfect specimen and the pupa was 

 healthy and perfectly formed., the blame lies with the caretaker of the cocoon. 

 Being very moderate in my estimate, I probably have raised during the last 

 fifteen years about 20,000 specimens from cocoons. I always open my cocoons 

 and I have not obtained a crippled specimen yet from a healthy pupa of which 

 proper care was taken. Please bear in mind that we therefore are able to guar- 

 antee that perfect specimens will emerge from our cut-open cocoons which we 

 sell, and the following season will always replace such cocoons as fail to produce 

 perfect specimens. By giving this guarantee we only have a loss on material of 

 1 % or 2% per year. 



"You further should not have made this misleading statement (page 63) : 

 'No inflexible rule has been published by which the male can be told from the 

 female cocoon.' Regarding this much has been written and very constant 

 characters are known. If this were not the case how could we fill the orders 

 of those of our customers who order for their crossing-experiments just so many 

 pupae of each sex? When I find spare time if you care to learn about it I shall 

 write a communication for your paper telling exactly the differences of sex as 

 shown in pupae."
