24 THE ENTOMOLOGIST. 



my query. In reference to P. tumidulum, I may add that I have 

 commonly seen this beetle feeding on the leaves of Heracleum 

 s2)hondylium, sometimes in great numbers, but, as yet, on no other 

 plant. — Thos. H. Hart; Kingsnorth, December 8, 1881. 



Additions to Notes on Diptera. — In the few observations 

 which I published in the last number of this Journal on 

 Parasitic Diptera and their victims (Entom. xiv. 285) I made 

 several omissions, which I am glad to have an opportunity of 

 correcting. Mr. Bignell has written to remind me that he sent 

 me, some time back, two specimens of Exorista lota, Meig., 

 which he had bred from lavvse of Acronycta psi ; also one of 

 ScopoLiA ocYPTERiNA, Zett., reared from Pterophorus tephra- 

 dactylus ; he has now forwarded me several other Tachinids, 

 lately bred by him, which I have great pleasure in adding to my 

 list ; they are as follows : — 1, Exorista vulgaris, four varieties? 

 parasitic upon the four following Lepidoptera, viz., Pieris rapes, 

 Mamestra persicarim, Tceniocampa populeti, and Oporahia dilutata. 

 2, Exorista gnava, Meig., from Orgyia piidihunda. 3, Exorista 

 fauna, Meig., from Cossus ligniperda ; and Phorocera con- 

 cinnata, Meig., from Notodonta chaonia. Mr. Fletcher has been 

 good enough to send me a notice of the following additions which 

 he has made to the list of parasites which he has bred, viz., 

 Exorista vulgaris, from Pliisia gamma and Vanessa urticce ; 

 Thryptocera setipennis. Fall., from Coccyx strobilella ; and a 

 small species of Degeeria, from Tinea cloacella. The two last he 

 sent to me for examination a year or two ago (when I could not 

 satisfactorily determine the name of the Degeeria), but I had 

 forgotten the circumstance when I drew up my paper ; Mr. 

 Fletcher also sent me at that time a specimen of Exorista 

 festinans, Meig., but did not know the name of the larva from 

 which it was bred, only that it was lepidopterous. Among the 

 general remarks which I made upon parasitic flies, I mentioned 

 that I had received some specimens of Dilophus vulgaris from 

 Mr. Bridgman, said to have been reared by Mr. F. Norgate from 

 Catoptria liypericana ; I have since had some correspondence with 

 the latter naturalist, and find that a mistake has been made ; and 

 that the above-named flies must have been mixed up and confused 

 with some parasitic species which had been lost. — R. H. Meade; 

 Bradford, December 17, lb8]
