EEPOKT OF THE ENTOMOLOGIST. 333 



He did not, liowever, describe the caterpillar. He remarks that it is 

 closely allied to the Earopean G. stigmatella. 



He states {Canadian Untomologiat, iy, 28) that "the larva mines the 

 loaves of the willow {Salix longifoUa) for a very short time ; then, leav- 

 ing the mine, it rolls the leaves from the tip npwards into varions forms 

 (usually a cone or helix of three spirals). * * * It frequently leaves 

 one roll and makes another, and, when ready to pupate, makes a dense, 

 semi-transparent web over it, upon the ground, not on the leaf, as in 

 many species. The imago emerges in the fall, and most probably 

 hibernates." He again remarks (I. c, v, 4G): " The cone sometimes oc- 

 cupies an entire leaf; the apex of the leaf is bent over, so that the left 

 edge touches the right one, to which it is fastened : then the leaf is 

 rolled spirally to the base, and the tip is used to close one end and the 

 base the other, so that the whole leaf is utilized. Many of the mines, 

 however, are by no means so perfect." Chambers has also bred it from 

 larvjc feeding on the silver-leaf poplar, but, though not occurring on the 

 weeping willow, it is common enough on many of our native willo\s's. 



DESCrarxiVE. — Larva. — Body of tbo usual cylindrical sliape; no cervical sliield. 

 Head small, considerably narrower than the prothoracic segment. Head and body 

 uniformly greenisli yellow. Only four pairs of abdominal logs, and these, Avith the 

 tlioracic feet, are of the same color as the body. Length, 6™"" to T"'".

 moth has left it.

 violaceous, flecked with brownish purple. Antenna) brown, tinged with j irplish, 

 faintly annulate with white at the base of each joint ; palpi pale purplish. The tri-

 rior margin is a little concave, the apex reaching the fold, and it has four small spots 

 of the general hue situated in it upon the costa. Fringe bluish fuscous. Posterior 

 femora white at the tivi and with a wide white band about the middle, and their 

 under surface entirely wJiito. Posterior tibia) and inner surface of intermediate tibia) 

 Avhito. Tarsi pale grayisli fuscous, faintly annulate, with white at the joints. Abdo- 

 men purplish fuscous, on a white ground. £xp.ins6 of the wings, half an inch (12.5'"™).

REPOET ON EXPEEIMENTS IN APICULTURE. 

 By Nelson W. McLaix, JpicuJlural Agent. 



UxiTED States Apiculturai. Station, 



Aurora, III,, November 17, 1885. 



Deah Sir: I have the honor to submit herewith my report of the experimental 

 work done at this station. 



In obedience to instructions received from you the 1st of June, 1S85, I selected a 

 location suitable for an apicultural experiment station, at this place. _ 



The work attendant upon the beginning of any undertaking is considerable. 



The building of fixtures suitable for the accommodation of bees and for carrying on 

 experimental work, securing bees, and doing that which is necessary to be done iu 

 establishing an apiary, consumed time. However, a number of interesting and valuable 

 experiments have been undertaken and progress has been made. 



I desire to acknowledge my obligations to yourself for valuable aid and suggestion 

 and to all those who liave kindly assisted me in my work, and especially the favor 

 shown me by the publishers of the following apicultural journals for liles of their 

 valuable papers, namely : 



The American Bee Journal, Messrs. Thomas G. Newman &, Son, Chicago, 111.; The 

 Dee-Kee2)ers' Magazine, MesnTS. King & Aspiuwall, New York City; Gleanings in Bee 

 Culture, Mr. A. L Koot, Medina, Ohio ; The American Apiciolturist (vols. 1, 2, Jind 3), 

 Messrs. Silas M. Locke & Co., Wenham, Mass. ; and to Messrs. D. A. Jones & Co., 

 Beeton, Ontario, Canada, publishers of T/ie Canadian Bee Journal. 

 Yours, very trnly, 



NELSON W. McLAIN, 



Agent in Charge.
