THE MONTHLY BULLETIN. 543 



ChUocorus hipnstvlaius (L.), a ladybird from Italy, which feeds 

 upon the black, citricola, purple and other sealas, as well as tlie mealy 

 bug; a good healthy colony at Fairoaks, where it has been breeding 

 during the summer, and seems to be established. It should be very 

 valuable. 



Exochomus i-pustidatus (L.), another ladybird from Italy, with food 

 habits similar to the above; colonized in good numbers at Fairoaks and 

 probably established. 



Paraleptoniastix abnormis Girault, a Sicilian parasite of mealy bugs 

 obtained in Sicily by the Insectary, and reared by the thousands; 

 colonized at many places in the State, and is established and breeding 

 at the present time ; a most promising species. 



Scymnvs hipunctatiis Kugelann, a ladybird enemy of the mealy bug 

 from the Philippines, bred in the Insectary by the thousands ; colonized 

 at several places within the State, and is now establi.shed. 



Apantcles glomeratus Reihn., a wasplike parasite of the imported 

 cabbage worm, Pieris rupee, introduced into truck farms along the Sac- 

 ramento River; was discovered breeding during the summer and is, 

 without much doubt, established. 



Zaloplwthrix mirum Ashmead. a parasite of the black scale from the 

 British West Indies; introduced in small numbers, and establishment 

 is doubtful. 



Leucopis sp.. a flylike predator on mealy bugs, introduced in small 

 numbers ; nothing is known as yet regarding the outcome. 



Several other species of lesser importance have been introduced but 

 nothing has been seen of them since, and their establishment is very 

 doubtful. 



In connection with this work much information regarding the natural 

 enemies of our pests in foreign lands has been secured and filed away. 

 This will he very useful in future work of this kind. 



In co-operation with Dr. L. 0. Howard, of the United States Bureau 

 of Entomology, we are compiling a catalogue of records of insect para- 

 sitism for the entire world. The great value of this catalogue to such 

 parasite work as we are attempting to do is obvious. 



Immense cjuantities of ladybirds have been distributed every year to 

 melon growers and others for the destruction of aphis. The exact prac- 

 tical value of this work is not yet known, but as it costs comparatively 

 very little, it will be continued until proper studies can be made in the 

 field. It has been very popular with the growers. 



In carrying out the foreign work we are under lasting obligations to 

 Dr. L. 0. Howard, Chief of the United States Bureau of Entomology, 

 Mr. C. P. Lounsbury, Entomologist of the Department of Agriculture 

 of the Union of South Africa, and his associate, Mr. C. W. Mally. to 

 Professor S. I. Kuwana, Entomologist of the Imperial Department of 

 Agriculture of Japan, and to Dr. F. Silvestri, of the Royal School of 

 Agriculture of Portici, Italy. 



Respectfully submitted.
