will wander about a few yards and soon die from exhaustion and 

 want of food, while such parasites as are well developed or in the 

 pupa state will mature and eventually fly off." 



Two parasites are here recorded as preying upon the species; 

 Tachina [Exorisia^ phyGitce, LeBaron, and Limner ia {^Banclius^ 

 fugifiva, Say, the first having been bred by Dr. LeBaron, and 

 the last by Mr. Wier. Excellent descriptions of the three stages 

 of the insect are also published and a variety {nehulella) of the 

 moth is characterized. 



In a foot-note Dr. Eiley states: ^'PliycUa nehido, Walsh, is 

 Myelois indigineUa, Zeller, as I am informed by the latter author, 

 who has had occasion to examine specimens which I forwarded to 

 him." But though Zeller's description of the insect was published 

 twelve years before that of Walsh, and the identity of the two 

 species is not questioned by Biley, he, together with many subse- 

 quent writers, has retained Walsh's name. 



A short account of the life history of the leaf -clumpier was pub- 

 lished by Prof. G. H. French in the seventh of the series of 

 reports . upon the insects of Illinois (pp. 249-250), in which, how- 

 ever, nothing new was added to the existing knowledge concerning 

 the species. 



During the year 1878 this insect attracted some attention be- 

 cause of its injuries in the vicinity of Cold water, Mich., where it 

 was popularly called the leaf roller. Prof. A. J. Cook, by whom 

 the facts were recorded (Trans. Mich. Pom. Soc. 1878, p. 22), 

 recommended the hand picking of the larval cases and the ap- 

 plication of Paris green as the most practicable remedies. 



About this time the insect seems to have made its way into 

 Georgia, if indeed it had not been there long before. In the 

 "American Naturalist" for May, 1881, Dr. Eiley notes the receipt of 

 specimens of these larvse (which he calls AcroTyrisis nebulo) from 

 Bryan county, where they were reported to be doing serious dam- 

 age. 



In Mr. Grote's "New Check List of North American Moths," pub- 

 lished in '1882, Phycis ind 'ujinella, Zeller, is given as the preferred 

 name of the species, nebulo, Walsh, being mentioned as a rejected 

 synonym. The only variety given is jnglandis, LeBaron, a form 

 affecting walnut, which, as Eiley has shown (4tli Eep. St. Ent. 

 Mo., p. 42), should rank as a distinct species. 



An excellent general account of the life history of the leaf 

 crumpler appeared in 1883 in Mr. Wm. Saunders's treatise oh "In- 

 sects Injurious to Fruits" (pp. 93-95); though in discussing rem- 

 edies it is recommended that the gathered larval cases be crushed 

 or burned, no mention being made of the seemingly better method 

 noted above by which the parasites are allowed to escape. 



Mr. F. M. Webster, in a paper read before the Indiana State Horti- 

 cultural Society and published in the transactions of that society 

 for 1885, briefly outlines the life history of the species, but records
