ADDITIONS AND COEEECTIONS TO THE BRITISH LIST OP 

 MUSCIBM AGALYPTRATM. 



BY J. E. COLLIN, P.E.S. 



(Concluded from Vol. xlvii, jpage 234). 



AGROMYZID.V. 



Odinia nnaculata, Meig. — This is the Milichia ornata of the " List." The 

 type of the geniis Milichia being speciosa, Meig., not congeneric with maculata, 

 it has been necessary to revive Desvoidy's name of Odinia for maculata and its 

 allies. 



*Odinia boletina, Zett. — This has been considered a synonym of the last 

 species, but I believe it is distinct. It is the commoner species in England, and 

 is to be found about tree fungi in the New Forest. Dr. Sharp and Mr. C. G. Lamb 

 were the first to call my attention to the species. 



Schcenomyza. — This genus is now generally considered to belong to the 

 Anthoinyidae. 



Agromyza. — The species of this genus are not well differentiated in iiublished 

 descriptions, and it is difficult to name them with certainty, but all the sjiecies 

 I have introduced are represented in Mr. Verrall's Collection and, I believe, are 

 correctly named. I have not made use of the genus Domomyza, Eond , becaiise 

 it was founded upon a character which is not of generic value. 



Agi-omyza reptans. Fin. — A common species nearly everywhere, which has 

 long been reputed to occur in Britain, and oixght not to have been omitted from 

 the " List." 



* Agromyza albitarsis, Zett. — Closely allied to the last species, but with paler 

 tibise and tarsi. I have seen it from Herefordshire, Kent, Cambridgeshii-e and 

 Suffolk. 



* Agromyza posticata, Meig. — The yellowish end half of the abdomen helps 

 to distinguish this species, which I possess from Herefordshire (one male taken 

 by Col. Yerbury). 



*Agroniyza abiens, Zett. — I have bred this from leaves of Cynoglossum, 

 gathered at Orford (Siiffolk). 



Agromyza flaviceps, Fln.^I caught a male of this pi-eviously i-eputed British 

 species at Chillesford (Suffolk) in May, 1910.
