August, '22] frost: eulia mariana on apple 311 



not as adults and that there are three complete generations. The seri- 

 ousness of this pest has been found considerably more than it was 

 thought to be at first. It is now considered as one of the most important 

 problems of the fruit growers of Pennsylvania, causing a considerable 

 amount of scarring and side injury to the fruit. The life history of 

 this species has been worked out in considerable detail and an ex- 

 tension circular from State College is in preparation and will be ready 

 for release in a short time. Bull, 169 from the Penn. State College 

 deals with this species as well as other leaf -rollers and bud-moths of the 

 apple in Pennsylvania. 



A third species of this genus Eulia quadnfasciana Femald has been 

 reported from New York state as a pest on apple but has not been found 

 injurious in Pennsylvania. It has been recorded from Canada, Maine, 

 New Hampshire, Massachusetts, New York, Pennsylvania and Del- 

 aware and no doubt has a general distribution throughout the North- 

 Eastem part of the United States. As far as the writer is aware it 

 feeds on apple alone. 



It appears that the genus Eulia includes many injurious leaf-rollers 

 of apple and that there may have been, in the past, some confusion of 

 species. It is hoped that this note may be of value in calling to atten- 

 tion the various species working on apple and that more concentrated 

 work may be conducted with these feeders. In Pennsylvania it is very 

 evident that the genus Eulia includes the serious leaf-rollers and the 

 marked difference in the life histories of these species make their control 

 different from the control of the species of the genus Cacoecia which 

 apparently are more injurious in New York state and portions of the 

 country further North. 



Thanks are due Mr. August Busck for the identification of these 

 species.

Scientific Notes 



The European Nitidulid beetle. Heterostomus pulicarius Linn., has caused con- 

 siderable damage to strawberry plantations in Columbia County this season and is 

 present in Saratoga, Albany, Niagara and Schoharie Counties in New York State. 

 In 1921 Mr. H. Morrison collected specimens of this beetle on the grounds of the 

 Arnold Arboretum near Boston. On May 2, 1921, a single specimen was collected 

 at Milford, Conn., by Mr. M. P. Zappe. W. E. B. 



The Anomalas collected at New Haven, Conn., in 1920, and again in 1921, have 

 recently been identified as Anomala orientalis Water. This insect is a native of 

 Ja-pan and some ten years ago caused much damage to sugar cane in Hawaii, but 

 parasites were introduced and proved successful in reducing the numbers of the
