lections, of greater extent in their field, than the general collections 

 enumerated. 



The collection of Mr. W. H. Edwards I have not seen. It is 

 probably as nearly complete as possible in the Rhopalocera, at least iri 

 those families which Mr. Edwards has not sold to pay for the magnificent 

 work he is issuing. 1 must not lose this opportunity of giving INIr. Ed- 

 wards credit for his careful and painstaking work in this group. What- 

 ever our individual ideas as to classification, no one can deny Mr. Ed- 

 wards credit for sincere and honest work, for faithful records and above 

 all for placing the results of his studies before us in such sumptuous 

 style. It is to be regretted that the collection did not go in its entirety 

 to some Public Institution— a lasting monument of his labors. 



In the family Hesperidcs of the Rhopalocera, the collection of INIr. 

 Eugene M. Aaron of Phi'adelphia is excellent. Mr. Aaron has spent 

 much time and money to complete his collection in this family ; but 

 owing to his numerous business engagements cannot unfortunately 

 devote much time to his collection at present, and cannot do much for 

 Seekers of information in this family. 



In the Sphmgidce, one of the most complete collections that I have 

 ever seen, native or foreign, is at Albany, in the possession of ?^Ir. Erastus 

 Corning, preserved by Mr. Wm. Gray, an Entomologist unknown to 

 fame, but with a fund of knowledge on the subject, not to be despised. 

 I doubt whether there are half a dozen collections of Sphingida? in the 

 world that are superior to this. It is practically inaccessible to students. 

 In the Geometridce. and PyralidcB the collection of Mr. Geo. D. 

 Hulst of Brooklyn is almost complete. This gentleman has of late, by 

 sacrificing Macro-lepidoplera in exchange and by purchase, secured an 

 almost complete representation of described forms besides many new 

 forms for description. No one has ever applied to Mr. Hulst in vam, 

 either for a sight of his collection or for determinations. 



In the Micro-lepidoptera as a whole the collection of Prof. C. H. 

 Fernald of Amherst, Mass., stands pre-eminent. In the Tortricida: the 

 collection will probably rank among the first in the world, while in 

 American forms it has no superior. In the Tineidcn it also ranks first 

 among American collections while in the Pyraltdce it is probably even 

 better than Mr. Hulst's in some of the families. 



Prof Fernald is always willing to encourage and aid the student in 

 this interesting field. 



In addition to these are several collections of still more limited scope 

 — that of Mr. Scudder of New England Butterflies", and that of Mrs. C. 

 H. Fernald of New England Macro-lepidoptera.
