Lesson XI. Miscellaneous. 



DR. HOLLAND ON FOODPLANT CHARTS. 



Dr. W. J. Holland, Director of the Carnegie Museum, Pittsburgh, Penn- 

 sylvania, writes: "Your very kind lines are before me, and I thank you for 

 the printed matter which accompanies your letter. I assure you that you have 

 done nothing wrong whatever in copying into your circular the names of the 

 foodplants of the various lepidoptera which you give, and I regret very much 

 that my book gives as little information in reference to the foodplants of many 

 species as it does. You are certainly doing a very good work in endeavoring 

 to inform others as to the progress made in reference to this branch of knowledge, 

 and I promise you that it will give me great pleasure to go over the list care- 

 fully when I have time to do so, and with the help of my assistants to try to 

 fill up some of the gaps, which I think we can do. One of my friends here 

 has been very industriously breeding larvae for the last four or five years, and I 

 think we can obtain from him a good deal of valuable information, more 

 especially as to the habits of the larvae of the moths." 



HOLLAND'S BOOKS. 



Dr. Holland adds: "Your kind recommendation of the books which I 

 have written, I assure you I sincerely appreciate. At the time that I undertook 

 the production of these two volumes, there was absolutely nothing easily accessible 

 to beginners in this country, which contained in compact form, accompanied by 

 good illustrations, that which the beginner always desires to know in reference 

 to such things. It may interest you to know that many thousands, both of the 

 "Butterfly Book" and of the "Moth Book," have found their way into the 

 hands of nature-lovers in this and even in other lands, and hardly a week passes 

 in which I am not requested to give information to beginners who are interested 

 in our favorite science." 



COMPLETING MONOGRAPH OF CATOCALAS. 



Dr. J. H. McDunnough of Decatur, 111., who is associated with Dr. 

 Barnes, writes: "We have been approached by the trustees of the American 

 Museum of New York with a view of completing the Monograph of the 

 Catocalas begun by Mr. Beutenmueller, but relinquished on his retirement from 

 the Museum. In order to do this satisfactorily it will be necessary to secure the 

 co-operation of collectors all over the country to obtain for us iertile ova from 

 living females, in order that we may study the early stages and have colored 

 figures made of the mature larvae. Try and secure for us several hundred eggs 

 from every species in your locality and mail us the paper bags with the females 

 inside, when dead. The ova hibernate so there is no danger of hatching on 

 the journey. We will pay at the rate of $1.00 per hundred for all eggs received 

 up to 200 of each species. A single female will lay from 1 00 to 600 ova. 

 I trust you will do your share toward making this Monograph a success."
