Island, July 7, 1921 and produced the beautiful moth, Cameraria 

 (Lithocolletes) picturatella Braun., and parasites, 

 namely, Rhicnopeltoidea a m s t e r d a m e 11 s i s Gir. and 

 an Encyrtid, the insects being determined through the courtesy of 

 Dr L. O. Howard, the moth by Mr Busck and the parasites by Mr 

 Gahan. 



Oyster scale (Lepidosaphes ulmi) was somewhat abun- 

 dant the last of June on soft maples at Kenmore, near Buffalo. The 

 young at this time had mostly established themselves under well- 

 developed scales, though a few were still crawling. The scale was 

 also somewhat numerous upon the smaller branches of elms at 

 Forest Hills and in a few instances had caused an appreciable amount 

 of injury. The infestation in this latter locality was also marked 

 by the presence of the elm bark louse (Gossyparia spuria) 

 on a few Scotch or English elms, though it was not observed upon 

 the much more abundant American elms. Cottony maple scale 

 (Pulvinaria vitis) was not very abundant in the Buffalo 

 area or in the vicinity of New York City. Putnams scale ( A s p i - 

 diotus ancylus) was numerous on a few soft maples at Ken- 

 more in the environs of Buffalo, fairly encrusting small areas of the 

 bark, though probably not seriously damaging the trees. 



A number of trees in Kenmore bore evidence the last of June of 

 being injured by the bleeding tree maggot (Mycetobia diver- 

 gens ) , and in several cases the slender, whitish larvae were 

 actually observed in the exudate and close to the living tissues. 



Borers were somewhat abundant, though not particularly injurious, 

 at Forest Hills, Long Island. Some of the trees were infested by 

 elm borers (Saperda tridentata), they having entered the 

 trunk at several places and also attacked the branches. The affected 

 trees had a trunk diameter of about 6 inches and showed a consid- 

 erable degree of vigor. Work of the leopard moth ( Zeuzera 

 p y r i n a ) was also noted on a few trees in the near vicinity, 

 though in no case was the injury severe. 



Wooly aphis (Schizoneura ulmi) appears to be gen- 

 erally present upon elms in the vicinity of Forest Hills. There were 

 a number of leaves upon trees here and there which had been 

 deformed by the leaf inhabiting generations and many of the knotty 

 enlargements caused by this insect were easily found. 



The spruce gall aphid (Chermes abietis) was somewhat 

 generally abundant on the western end of Long Island and in some 

 localities caused material injury. Infestations were also noted in
