species, and neither of them are the Anthomyia betas of 

 Curtis. The flies are in the hands of Mr. Walker, the 

 Dipterologist, by whom they will be exhibited at the next 

 meeting of the Entomological Society of London. They came 

 out of the pupa-state, ]\Iay 1st, and are still coming out. 

 I shall be happy to send some for exhibition at the London 

 Microscopical Society, or to any gentleman who may wish 

 to see them. — Wm. Winter, Aldeby, near Beccles. 



The Mangold-wurzel Fly.— I am sorry to announce the 

 unwelcome news that this fly [Anthomyia beta), which 

 occasioned so much damage to the mangolds last year in 

 several parts of the country, and which I described in the 

 January number of the ' Microscopical Journal,^ has again 

 made its appearance, and that the crops are suffering very 

 considerably. The larv(B attack the leaves of the plant earlier 

 this year than last. As soon as the cotyledonous leaves are 

 above ground, there may be found upon them the ova of this 

 pest. We may anticipate very serious mischief, I am afraid, 

 to the mangolds, for the above reason, but cannot be sur- 

 prised, when it is remembered how exceedingly mild last 

 winter was. 



Beetroot in gardens — which is also attacked — may be saved 

 by crushing the ova on the under surface of the leaves from 

 time to time, but large fields of mangolds are out of the reach 

 of so simple but effectual a cure. — W. Houghton, Preston 

 Rectory, Wellington, Salop.
