in Japan and working upon Japanese beetle parasites there. A fairly large proportion 

 of these cocoons were apparently in good condition upon their arrival at the laboratory 

 and emergence has just commenced. 



The Japanese beetle has been much more abundant during the present season than 

 in any previous year and over a wider area. Serious damage has been caused by the 

 immense numbers of the beetles to the foliage of many trees, especially fruit trees 

 and certain varieties of shade trees. There has been important injury to early fruit, 

 particularly early apples and early peaches. Recent visitors at the Japanese Beetle 

 Laboratory, Riverton, N. J., include: Dr. E. D. Ball, Dr. L. O. Howard, Dr. A. L. 

 Quaintance, and Dr. C. L. Marlatt from the U. S. Department. Other visitors in- 

 clude Dr. T. J. Headlee, State Entomologist of New Jersey, and Mr. H. B. Weiss of 

 the State Department of Agriculture, New Jersey, and Prof. F. Rasmussen and Prof. 

 J. G. Sanders of the Pennsylvania Department of Agriculture. A committee of the 

 New Jersey State Board of Agriculture also recently spent part of a day at the 

 Laboratory looking over the beetle situation. 



Mr. R. Owen Wahl, Carnegie Student from South Africa, who spent the months 

 from February to July in this country visiting field laboratories and experiment 

 stations, in a letter to Doctor Howard written from Vancouver, B. C, July 21, on the 

 eve of sailing for Austraha, said: "Before leaving the continent, I would like to 

 thank you, Doctor Quaintance, and all the host of entomologists I have met for their 

 unfailing consideration and kindness to me. Always have I found the utmost hospi- 

 taUty and good fellowship and no one spared any trouble to make my stay pleasant 

 as well as profitable If you have any means of conveying my sincere thanks to 

 them I am sure you will do so. I am leaving the United States with great regret, but 

 will always have the keenest interest in your wonderful country, and the thought of 

 all the workers in entomology doing their bit will always be an inspiration to me." 



Mr. G. A. Runner, in charge of the grape insect work for the Bureau of Entomology- 

 at the Federal laboratory at Sandusky, Ohio, reports severe injury from grape leaf- 

 hoppers in vineyard sections of New York, Ohio, and Michigan, and that large num- 

 bers of grape growers have commenced spraying operatons for control. In Ohio 

 and Michigan the grape-berry moth has caused more than the usual amount of 

 damage to the grape clusters by feeding on the stems or buds during the blossoming 

 period. At Lawton, Mich., on June 8, Mr. Runner found cocoons of the grape-berry 

 moth on the grape leaves. This shows an unusually early development of the 

 larvae, as grapes were just out of bloom, and shows that early appearing larvae are 

 able to complete fully their growth without entering the grape berries. At Paw Paw, 

 Mich., bud clusters infested with the grape-blossom midge (Contarinia johnsoni 

 Sling.) were observed on June 8. The insect had not been reported from that section 

 previously. 



The citrus black-fly, introduced into the Canal Zone from the West Indies, is rapid- 

 ly spreading, according to Mr. James Zetek, who is in charge of the field station there. 

 This pest is now well distributed for about twelve miles out from Panama City, all 

 along the Canal Zone, and has been introduced in the interior at Aguadulce. Two 

 entomogenous fungi, Aschersonia aleyrodis and Aegerita webberi, are following the 

 black-fly, but are not ;ufficient to check it. Agriculture is still in its infancy in 

 Panama so that practically no control or restrictive measures are being taken against
