upper side of each abdominal ring are two transverse rows of tooth-like 

 projections. By means of these, the pupa just before transforming to the 

 moth, works its way to the mouth of the burrow, so that the perfect insect 

 may escape ; which usually occurs in the latter part of June or first part 

 of July. 



The eggs are doubtless deposited some time in July, and are of a 

 dark brown or somewhat purplish color. The ovipositor of the female 

 being extensile, she is enabled to place them into the deeper cracks and 

 crevices of the bark. The young worms which hatch from them are dark 

 brown, with large heads. They are active and commence spinning as 

 soon as they are born. 



Prof. Thomas stated the action taken by the State Society, at its 

 late meeting, in appointing a committee to make and present plans for 

 concerted action among fruit growers, to protect themselves from the rav- 

 ages of insect enemies. 



Secretary Galusha read, from the report of tliat meeting, extracts 

 showing the plan as there presented by Prof. Thomas, and solicited the 

 co-operation of this Society. 



Mr. McWhorter moved that a committee of one or more members 

 of this Society be appointed to act with the committee of the State Hor- 

 ticultural Society, in the matter proposed by Prof. Thomas. 



This motion was amended by striking out tlie words or more, and 

 Mr. McWhorter was unanimonsly chosen as said committee.

The following letter, from Dr. J. A. Warder, was read and ordered 



printed : 



" North Bend, O., January 21, 1876. 



"Lewis Ellsworth, Esq., Pres't Horticultural Society of Northern Illinois. 



"Dear Sir : I beg you to accept for yourself, and tender to your worthy associntes, 

 (many of whom, with yourself, I am happy to call my friends,) the regrets that I shall 

 not be able to accept your proffered hospitalities at Crystal Lake, next week. 



" I have for some time been anticipating the ])leasure of speniiing this week at 

 Des Moines, Iowa, and had expected to return via Chicago, at its close, or early next 

 week, in lime to be with you, also. Indisposition, last week, put Des Moines out of the 

 f[uestion; but I was llattering myself that convalescence was jirogressing favorably, and 

 that by Monday next I should be able to travel, and had already begun to ])lan how I 

 might contribute my share of your entertainment, when positive orders came from the 

 consulting physician, in whom I have great confidence, that I should not think of talk- 

 ing or lecturing, much less of traveling northward or prairieward. So, you see, an 

 embargo is laid upon my movements, for the present, at least. 



" I do so enjoy meeting my horticultural friends, and had anticijiated so much 

 pleasure from these two meetings, particularly, that this medical ukase is indeed a sad 

 disappointment to your friend, WARDER. 



" Present me, most respectfully, to your excellent associates."
