Stictomischus discedens Otten. Types not seen ; it seems possible that the species 

 might be a form of elegans. Otten's material was reared from a Dipterous mine on 

 Pulmonaria sp. 



Britain, Sweden, Germany, Central Europe. Common in Britain. 



Biology. Chiefly a parasite of Agromyza reptans Fin. on Urtica dioica L. ; but 

 also parasitizes A. anthracina Mg. on the same plant ; Phytomyza symphyti Hend. 

 on Symphytum officinale L. ; and Phytobia labiatarum (Hend.) on Teucrium scorodonia 

 L. (British records, material bred by G. C. D. Griffiths and K. A. Spencer). Imagines 

 May- June and Sept.-Nov.

Miscogaster gracilipes Thomson. Thomson's description of the male (1876 : 240) 

 applies well to the male of rufipes Walker and there is a male of this in his series. 



Miscogaster fulgens Delucchi. Type, Germany, Mindelheim, 10. v. 1952, from 

 Agromyza reptans Fin. (Groschke) in coll. Delucchi (not seen by the writer). From

 on Urtica dioica L. ; also from A. rufipes Mg. on Echium vulgare L., Cynoglossum 

 officinale L., Borago officinalis L., Lycopsis arvensis L., and Myosotis sp. ; and from 

 Phytomyza symphyti Hend. on Symphytum officinale L. (G. C. D. Griffiths and A. H. 

 Hamm) ; material in BM(NH), and Hope Dept., Oxford. On 28.vi.195g I observed 

 females ovipositing in mines of Phytomyza atricornis Mg. (agg.) in leaves of Echium 

 vulgare L. in my garden ; females were also seen on the leaves in July. Imagines 

 (in Britain) May- July and Sept.-Nov.
