EXPERIMENT STATION REPORT. 579 



trees were to be sacrificed in the hope of saving the lady bird, or 

 whether the trees should be treated to save them, at the risk of 

 destroying the insect. The decision was usually in favor of 

 spraying and whether from this or because of the severe winter 

 the insects had practically disappeared. On this point of temper- 

 ature and se\^erity of winter weather, it should he said that while 

 the winter was severe and the temperature low for Central 

 Georgia, it was mild and the temperature high compared with 

 even a moderate winter in New Jersey. If the Georgian winter 

 of i903-'o4 was really in fault, there can be little reasonable hope 

 of establishing the insect in New Jersey. 



On Wednesday the 20th, after a visit to the Hale Orchards, 

 Mr. Newell and myself made a careful examination of the Wright 

 Orchard where in 1903, Chilocorous sijmlis\\?i<l flourished. For 

 over an hour we looked over tree after tree where the insects had 

 been most abundant without finding even a single specimen in any 

 stage. There were plenty of infested trees and, while the 

 orchard had evidently been sprayed, the work had been carelessly 

 done and there was an abundance of food for many hundreds of 

 beetles and their larvse. 



The next point was the Fernoyd orchard which had been col- 

 onized in 1903, and where Mr. Scott had found some specimens 

 in May, 1904. We had been advised of the exact point where the 

 insects had been seen and after some search we ffjund a few adults 

 and later 1 1 larvae and 9 pup^e, all oi which were sent into^ New 

 Jersey and duly received later. This portion of the orchard was 

 at the edge of a grove of tall trees and near a packing shed or 

 cabin which possibly furnished shelter for the insects during the 

 winter. At all events no specimens were found else-.vhere in the 

 orchard. Quite a variation was observed in the larvae, some 

 examples having a transverse banding almost as marked as in 

 bivulncrus. 



From such information as could be obtained it appears that the 

 insects were then less abundant than they had been in May and 

 there seemed no doubt that, as a factor in scale control at Fort 

 Valley, they could not be considered. This seemed to be the gen- 

 eral opinion and I could not learn of any one at all inclined to 

 rely upon the work of this insect for freedom from scale attack. 



On the evening of the 20th, went by train to Marshallville, 8 

 or 9 miles south of Fort Valley, and on Thursday, July 21st, 

 visited the Rumph Orchard where the original colony obtained 

 from Washington was first introduced. This is a very large 

 orchard, covering several hundred acres and containing many
