year. Our sprayiug apparatus will also be increased by several more gas 

 spraying machines and many barrel pumps, which will enable us to treat 

 all the trees within the infested area within a very short time, thus destroy- 

 ing the larvae when still young and most susceptible to poison. 



The past season has been a bad one for most insects and many species have 

 been abundant this year that were not injurious last season. The elm leaf 

 beetle has been controlled by spraying with arsenical poisons for the destruc- 

 tion of adults and larvae, supplemented by destroying the pupae with kerosene 

 emulsion in August. The bag worm was very abundant in certain centers 

 early in the season, and serious injury was averted by collecting the bags 

 before the eggs hatched. 



Several rainy days during the winter were utilized by lectures to the 

 men employed in this work. Not only were the fundamental principles of 

 arboriculture presented but also the work against insect pests, their cbaractei'- 

 istics, etc., were duly discussed. These talks were copiously illustrated with 

 specimens and colored slides. The gypsy and brown-tail moths were dis- 

 cussed so that should either of these species ever invade Brooklyn, the more 

 intelligent of our men might be able to identify them and call attention 

 thereto. The beneficial effects of these meetings have been proven by the 

 numerous "new" insects brought in for identification, and by the better grade 

 of work done by the men. At present there is a force of 163 men attending 

 to the street trees of Brooklyn alone.

Muscina stabulans (Fallen). During the month of July, 1907, my wife 

 in preparing beets for the table discovered that the stems were infested with 

 maggots and called my attention to the matter. The larvae were placed in a 

 breeding jar, together with the stems, which were not decayed at this time, 

 though they speedily became so. The larvae began pupating on July 14, the 

 first fly appearing on the evening of July 22. Dr. L. 0. Howard, to whom the 

 adults wei'e submitted for identification, pronounced the insect to be the 

 above named species. They were all undersized individuals and some half 

 dozen or so were reared from the stems. During the past summer I found 

 some very young dipterous larvae upon a leaf of the common rhubarb or pie 

 plant, which had begun to decay. There issued therefrom no less than 35 

 full-sized specimens of Muscina stabulans. The larvae were found on the 25th 

 of May and the flies began to issue on June 10. This species seems to be most 

 common in houses about Harrisburg during the months of May and June, 

 almost completely disappearing by July 1.
