Chrysotoxum bicinctum, L. Birmingham. 

 C. sylvarum, Mg. Dover. 



C. 8-maculatum, Curt. Plynibridge, June 25th. 

 Microdon devius, L. Birmingham. In Verrall's list this is 

 marked uncertain. As three specimens were taken this year, 

 this will satisfactorily establish the species as British. 



Conopidce. 

 Conops vitellinus, Loew. Three from Birmingham. 



CEstrida. 

 Gastrophilus equi, F. One from near Birmingham. 

 Muscidce. 

 1. Tachinidce. 

 Echinomyia grossa, L. Ivybridge, Aug. 11th. 



2. Sarcophagidce. 

 Theria muscaria, Mg. I named a specimen of this species 

 for someone early in the year, but cannot recall my correspondent's 

 name, and I see the species has been recently introduced to our 

 lists by someone, so that in this instance I am forestalled. In 

 Verrall's list it is included among the "probably British" 

 species. Walker does not mention it. 



Cynomyia mortuorum, L. The Bev. F. Walker showed me a 

 long series of this fly, taken in Iceland, where he found them 

 lying dead near the windows inside a large building, — if I re- 

 member rightly, a church. 



3. Muscince. 



Calliphora vomitoria, L. Aberdeen ; London. Dr. Walker 

 has taken it in Iceland. The very common species erythrocephala 

 is usually mistaken for this species. 



C. grcenlandica, Zett. Birmingham. Dr. Walker has taken 

 it in Iceland. I have not seen a specimen of this species in 

 London this year, though I took several here in 1888. 



4. Anthomyidcs. 



Lasiops semicinerea, Wied. One taken by Mr. Bradley near 

 Birmingham. This appears to be new to Britain, not being in 

 Verrall's list ; but Walker, after his described species of Antho- 

 myia, adds, with others, an A. semicinerea, Wied. The species 

 is so distinct that it cannot possibly be mistaken. 



Lispe tentacidata, De G. Plymouth, August 12th. 



5. Acalypterata. 

 Norellia spinimana, Fall. Staines, May 23rd. 

 Scatophaga squcdida, Mg. Aberdeen. 



8, ster cor aria, L. Dr. Walker found it common in Iceland 

 last summer.
