parts of Georgia. Upon going again to Georgia this past spring 

 he had visited four or five of these colonies, and in only two had 

 a favorable increase in the number of individuals been made. A 

 colony established at Marshallville contained a year ago 40,000 

 beetles, but this spring there were none to be found. This Mr. 

 Kotinsky attributed to the fact that the part of the orchard con 

 taining the beetles had been sprayed with lime, salt, and sulphur 

 wash, and that this had killed them. A colony had accidentally 

 established itself in an adjoining orchard, but owing to improper 

 care, it was weak in numbers this spring. 



The' immense colony of what afterward turned out to be C. 

 bivulnerus, found in a section of plum trees in this same orchard 

 feeding upon Pulvinaria amygdali Cockerel 1, with which these 

 trees were badly infested, was at first mistaken for the imported 

 beetle, owing to the large numbers of pupae found congregated 

 together. 



Taking it all in all, it may be said that owing to improper care 

 of the various colonies established in Georgia due to ignorance 

 of the habits of the beetle on the part of the orchard managers 

 none of the colonies was in a very thriving condition. Mr. 

 Kotinsky said he suggested to these managers to collect and trans 

 fer a colony of the beetles, each summer, to a section of the 

 orchard they did not expect to spray the following year since 

 he was informed that no orchard is entirely sprayed each year. 



Mr. Kotinsky ventured the supposition that possibly the colony 

 on plum trees, referred to above, might be a cross of the two 

 species (Chilocorus bivulnerus and C. similis}, retaining the 

 structural characters of bivulnerus and the prolific breeding of 

 similis. 



In conclusion, he observed that in shipping the ladybirds alive 

 precautions must be taken that there is not, in the shipping cases, 

 sufficient ventilation to cause a drying up of the enclosed twigs, 

 since these beetles suffer much more from lack of moisture than 

 from lack of food. All possibility of the rattling of the enclosed 

 twigs must be avoided, also, and this, it seems, can only be ac 

 complished by tacking the twigs to the box in which they are 

 packed, for some evaporation will take place under all circum 

 stances and this will cause the twigs to contract so as to become 

 loosened.
