EXORISTA HORTULANA, McigCll. 



I have received this s^Decies from Mr. Bridgman and also 

 from Mr. Porritt, by both of whom it was bred from Acroiiijcia alni. 

 ExoRisTA AFFiNis, Fallen. 



Mr. Bridgman sent me specimens of this species bred, 

 together with the last, from Acronijcta alni; and I have also 

 received it from Mr. Fitch, who reared it from a larva of the 

 same species. It appeared such a remarkable circumstance that 

 two distinct but closely-allied parasites should be bred at the 

 same time from the same larvge that I was led to examine them 

 very carefully, and suspect that the flies which I have severally 

 named E. liortulana and E. (ijjinis are only varieties of the same 

 species, which is probabl}^ now, as it does not exactly agree with 

 the descriptions given of either of the above species. 



EXORISTA LOTA, Mcig. 



Mr. Dale sent me specimens bred from Tcotiucdiitjni stabilis ; 

 and Mr. Fletcher one from Aoviiijcta 2)si.

 reared from the larva of the same species.

 Mr. Fletcher has bred this fly from Acronycta dccris.

 Zygcena Jilii) end nice. 



Baumhaueria vertiginosa, Meig.

 tcphradactylus. 



Thelaira leucozona. Panzer.

 arista — has been bred by Mr. Butler from Chdonia caja.
