The species occurs throughout Europe and in habits is the counter- 

 part of C. hipustulatus. 



Exochomus quadripustulatus was colonized at Fair Oaks in the same 

 orchard with C. hipustulatus and under the same conditions. Approxi- 

 mately three hundred and fifty individuals were placed in the orchard 

 on September 17th. It is as yet too earlj^ to say whether or not they 

 are breeding. 



These ladybirds should become valuable additions to our insect fauna.

 introduction into California of a new Chaleidoid parasite of the citrus 

 mealy bug. This species has been described by Mr. A. A. Girault of the 

 United States Bureau of Entomology as Paraleptomastix abnormis} It 

 w^as obtained in small numbers by the Insectary during the summer of 

 1914, at Palermo, Sicily, and shipped to Sacramento, where its life his- 

 tory was worked out and where it has been bred extensively in confine- 

 ment ever since.

 green lemons kindly furnished us by the Limoneira Company of Santa
