Note on the Trachys nana of British collections. — A recent examination of 

 various species of Trachys from the south of Europe, has led me to examine also tlx3 

 T. nana of British collections ; and, much to my astonishment, I find that our so- 

 called examples of that species do not in any way agree with the description of 

 Fabricius's insect of that name, as recognised by modem authorities on the Bupres- 

 tidcB ; they have not a (comparatively) large triangular scutelluni, a distinct lateral 

 carina to the elytra starting from the humeral callus and running parallel with the 

 margin almost to the apex, nor is the thorax deeply foveolated near the anterior 

 angles. Our species has a small pointed scutellum, is without lateral carinse to the 

 elytra, and without deep foveas near the anterior angles of the thorax ; it is evidently 

 to be referred to T. ptimila, 111., a variable and widely distributed species, occurring 

 in France, Spain, Italy, Germany, Greece, Algeria, &c., and, according to Marseul 

 (Mon. des Buprest., L'Abeille, ii, 515), is attached to Marruhiwm vulgare. I havo 

 received T. pumila in numbers from Mr. J. J. "Walker, who has foimd it at Corfu 

 and Gibraltar ; in England I believe it has only (as yet) been found at Micklcham. 



Stephens (the introducer of the species into the British list) in his " Manual," 

 says of T. nana, " elytra, within the margin a short lateral ridge," as that species- 

 should have ; but T. nana does not exist (as the " Manual " leads one to infer) in his 

 collection at the Brit. Mus., as I have satisfied myself by examination, so I think 

 the record (and locality, " Coombc Wood ") must be considered erroneous. Our 

 species is identical with examples labelled T. Fandellei, Fairm., in the Brit. Mus. 

 Europ. coll., to which species, however, it of course bears no resemblance. 



It is rather odd that two of our three British species of Trachys should have 

 been eiToneously recorded, viz., T. pygmma (= troglodytes) and nana (= pumila).—

Notes on British Terehrant Hymenoptera. — The under-noted Cynipidm may be 

 added to our lists : — 



Aphilothrix autumnalis, Hartig, Germs. Zeits., 1811, p. 336; Mayr, Die Mittel- 

 eurapaischen Eichcngallen, p. 24, pi. iv, fig. 31. The galls of this species I have 

 found in the autumn in Caddcr Wilderness, but have not yet succeeded in reariug 

 the flies. 



Andricus cBstivalis, Giraud, Verb. z.-b. Ges. Wien., 1859, p. 356 ; Mayr, I. c, 

 p. 55, pi. vi, fig. 79. I have an Andricus taken on 20th May at Ardlui, Loch Lomond, 

 which must I think be either the above or a new species. The galls appear on th© 

 male catkins of the oak. 



Ceroptres arator, Hartig, I. c, p. 343, 1 have bred from some galls of Andricus 

 noduli got in Kenmuir Wood. 



.^gilips abietina, Dahlbom, Onyeh. och Callasp. Syn., tab. No. 25 ; Thomson, 

 Ofv., 18G1, p. 412. Taken in Inverness-shire. ^. stibulifera, Thomson, I. c. Taken 

 in the same locality. The species of this genus are rather difficidt to determine, and I 

 hence I am a little dubious if I have named these two species correctly (Mr. 

 Marshall, however, thinks that I have done so). 



Tetrarhaplra tetratoma, Thomson, I. c, 399, 8. From Glasgow districts, where 

 the remaining species were also taken. 



Pentacrita pentatoma, Thomson, I. c, p. 398, G. P. albipennis, Thomson, I. «?., 

 p. 399, 7 ?
