Leaf-mining Diptera in 1884. — The Snow-berry bushes 

 {Chiococcos racemosa), planted frequently in pheasant-preserves 

 for the sake of the white berries, which are said to be relished by 

 our game birds, have been this year covered with their pretty 

 white mines. Scarcely a leaf has been without its characteristic 

 scroll. I noticed the fly, indeed, ovipositing at the close of 

 April, and the mining of the larva was easily seen in June, 

 and even earlier. The fly appeared in the beginning of July, 

 and is by no means difficult to rear. I believe this to be the 

 identical species recorded by Weyenbergh as occurring on the 

 Snow-berry at Haarlem, and named by him " Haarlemensis." 

 He says that the second generation remains in pupahood 

 throughout the winter. The leaves of the fragrant white 

 melilot gave evidence, apparently, of the mines of the Phyto- 

 myza affinis, of Macquart, the pupa-case being black, and im- 

 bedded in the pulp of the leaf. I was much interested in the 

 exits of the fly, but, unfortunately, all were ichneumoned, and 

 not a single miner appeared. Judging, however, by the artisti- 

 cally formed mine and other attendant circumstances, I have 

 little doubt that the miner was P. affinis, of Macquart, my old 

 acquaintance of 1882 ; and I am the more led to think so since 

 the pea and the melilot are so closely allied. That most poly- 

 phagous of the Phytomyzidse, P. albiceps, emerged on the 31st of 

 July from its pupa-case attached to the leaf of Angelica sylvestris. 

 Kaltenbach actually mentions sixteen plants that furnish food to 

 this ubiquitous little fly. Among the plants recorded are seven 

 of the Composites, four of the Labiates, three Umbellifers, a poppy 

 wort, a Valerian wort, and one of the Borage worts. I could add 

 a few more, chiefly from among the ComiDosites. The last miner 

 I have to record is Phytomyza glechoma, Kaltenbach, that makes 

 a conspicuous scroll on the surface of the ground ivy leaf, that 

 reminds me somewhat of the appearance of a volume of steam 

 from the funnel of a railway-boiler. The mines have been not 

 uncommon this year on plants that have grown in shady places 

 overhung with tree foliage. As I gave a detailed account of this 

 Phytomyza in the December number of the ' Entomologist ' of 

 last year (Entom. xvi. 285), it will be superfluous to repeat the 

 account. — Peter Inchbald ; Fulwith Grange, near Harrogate.
