Mr. Smith considered Mr. Weed's experiments with Paris green 

 against liipimdamia <;onvergens not conclusive as indicating their phy- 

 tophagic habit, as the beetles might have been feeding upon plant lice 

 and thus have been poisoned by the Paris green. 



Mv. Popenoe stated that he had found Rippodamia feeding upon rust 

 spores. 



Mr. Weed described the treatment of Cotton for the Cotton Worm by 

 means of a long pole carrieil across a mule's back with a bag of Paris 

 green hanging to each end of the pole. In this way four rows of Cotton 

 can be treated at once with undiluted Paris green. 



Mr. Webster stated that in Louisiana four sacks were thus strung 

 upon a single pole. 



Mr. Kellicott presented the following note: 



NOTE ON THE HORN FLY IN OHIO. 



By ]>. S. Kkllicott, Columbus, Ohio. 



Since the full accouuts of the Horn Fly given in Insect Life and else- 

 where, I, as many others doubtless, have sought for it wherever I had 

 an opportunity. I remember no reports of its occurring west of the 

 Atlantic border, but it certainly has a foothold in central Ohio. Dur- 

 ing the first week of July last I found it in great numbers on the farm 

 of Mr. A. Freed, Pleasant Township, Fairfield County. Large patches 

 were seen on the backs and about the horns. The animals referred to 

 bad been dehorned, but the fly, true to its instincts, congregated about 

 the stumps. At Sugar Grove, 8 miles south, a few were found, whilst 

 at Kockbridge, 4 miles farther down the Hocking Valley, none were 

 to be found. There appears to be none north of the first-mentioned 

 station, as I had a fair opportuniry to examine cattle at Lakeside (Lick- 

 ing reservoir). They have not been seen at Columbus. It seems from 

 the limited observations I have been able to make that it is spreading 

 southward from near Lancaster. The Baltimore and Ohio Railway 

 passes but a short distance north of this place, and it is easy to see 

 that it is possible, or indeed probable, that it was introduced by trans- 

 portation in cattle cars from the East. 



Mr. Smith stated that the Horn Fly was not injurious in any part of 

 New Jersey last year, stockmen adopting the plan of spraying with 

 fish-oil compound. He also stated that the plastering of the dung was 

 practiced in his State in small stock yards. 



Mr. Howard said that even in large grazing fields this latter plan is 

 often practicable in spite of the objections which stock-growers urge. 

 At the time when the flies are ovipositing the cattle are generally con- 

 gregated in some one spot for shade. 



Mr. Lintner said that he heard of the fly in the southeastern portion 

 of New York State.
