Cole (F. R.). Notes on the Lunate Onion Fly, Eumerus strigatus 

 (Dip., Syrphidae). — Entom. News, Philadelphia, xxxi, no. 2, 

 February 1920, pp. 31-35, 1 fig. 



Notes and observations on Eumerus strigatus, Fall., are given, 

 additional to those of Metcalf [R.A.E., A, vii, 356]. This fly was 

 first observed infesting onions m the United States in July 1917, 

 when the females were found crawling into crevices in the ground 

 and ovipositing in the leaf-sheaths just above the bulb. Onions 

 taken from the ground at this time contained larvae of several sizes 

 that pupated in the laboratory in March and April, and emerged as 

 adults in late April and early May, a httle later than individuals of 

 Hyhmyia antiqua from the same bulb. The onion bed was almost 

 entirely destroyed. The insect has also been recorded from British 

 Columbia, where it has been collected near large onion farms, and all 

 along the Pacific Coast from British Columbia to Cahfornia. There 

 may be biological races of this fly, as in the case of the apple maggot 

 [Rha{joletis 'pomoneUa]. The adult is described and figured. 



LEGISLATION. 



Jardine (N. K.). Legislation regarding Shot-hole Borer {Xyleborus 

 fornicatus, Eichoff.). — Trop. Agriculturist, Peradeniya, liv, no. 1, 

 January 1920, pp. 31-34. 



The legislation that has been passed in Ceylon regarding Xyleborus 

 Jornicatus, Eich., since 1903 is here reviewed. 



The position from 1st January 1920 is as follows : — -Infested areas, 

 that is estates or parts of estates declared infested, cannot have 

 permits granted to them, and no tea plants or parts of tea plants 

 other than tea seed or leaf for manufacture may be removed from 

 them. Tea plants may be removed from estates that are not infested 

 areas, provided that a permit is obtained from the Director of Agri- 

 culture ; the permit must state the number of plants, their source 

 and their destination. 



It follows that infested estates should not establish tea nurseries 

 for the sale of plants, but non-infested estates may do so if they 

 are willing to take the risk of infestation.

Gaz. Canada, Ottawa, vii, no. 1, January 1920, p. 12. 



Following upon the discovery of Psylla mali, Schmidb., in Nova 

 Scotia during the summer of 1919 [R.A.E., A, vii, 506] a quarantine 

 regulation has been added, under date 28th November 1919, to the 

 Destructive Insect and Pest Act, which forbids the removal of any 

 apple stock from within a radius of five miles of the town of Wolfville, 

 where the pest was found, without a certificate of inspection guaran- 

 teeing that such stock has been duly treated in accordance with the 

 instructions of the Department of Agriculture and that it is free 

 from infestation with P. mali.
