EXPERIMENT STATION REPORT. 577 



the time I visited the place not much was to be seen of Coc- 

 cinellids in any stage; but Mr. Maul informed me that earlier 

 they had been much more abundant ; a statement borne out by the 

 number of cast larval and pupal skins that were found. Close 

 examination of these cast skins showed, however, that it was not 

 the introduced Asiatic species but the native form that had been 

 present. 



In most of the places spraying had been done during the win- 

 ter; but not in all and no difference was observed so far as preva- 

 lence of Coccineilids is concerned between the sprayed and the 

 unsprayed orchards. Indeed, there is no reason why there should 

 have been any, especially where the lime and sulphur mixtures 

 were used. The lady-birds hibernate as adult beetles, not neces- 

 sarily on the trees, or, if on the trees, then under such shelter as 

 would protect them from anything save, possibly, an oil spray. 

 There was, unfortunately, in every case plenty of food left for any 

 hibernating beetles and even for a good brood of larvse ; indeed 

 the natives de\'eloped under these conditions. 



The winter conditions were very severe, the temperature being 

 low for a much longer period continuously than usual in our 

 State, though the thermometer did not go as law as it has done 

 in my experience. Nevertheless the weather was severe enough 

 to harm many trees and shrubs and it may be responsible for the 

 apparently complete disappearance of the species. 



In my report for 1903 the following paragraphs are found: 



"In Georgia, conditions seem to be much more favorable, for 

 the colony there, introduced at the same time that I received 

 specimens in New Jersey, has noAv multiplied enormously. Mr. 

 Marlatt writes on this point as follows : 



"The rather successful Georgia colony, to which I referred in 

 my letter to you of the 3rd of July, was visited by Mr. Kotinsky 

 and Mr. Scott a little later, and found to be in the most flourish- 

 ing condition. They estimated that in this orchard of some 

 17,000 trees there was upwards of 30,000 or 40,000 beetles, 

 these creatures having spread all over the orchard. Adjacent to 

 this orchard is a much larger one, belonging to the same person, 

 of 250,000 trees, also infested by the scale, intoi which the beetle 

 wnll soon migrate or be carried. Furthermore, a good many 

 colonies have been sent out locally from this one, and in one or 

 two instances it seems to have gone to adjacent orchards of 

 itself." 



"If, as is to be expected, these insects hibernate well in Georgia, 

 it will be my effort to secure a goodly supply early in the season
