Observation. — The figures of the left leg of Phytoptu^ 

 tristriatus and of P. tristriatiis var. carinea, magnified 550 

 times, at p. 127, are given in order to show the form of the 

 "holding-claw" or " feather-hristle " of the Phytoptus on 

 somewhat larger scale than it is shown in the figure of P. 

 pijri ; and whilst I refer readers desiring complete description 

 and perfect representation of the gall-mites to the works 

 mentioned below, I desire to record my sincere thanks to Dr. 

 Nalepa not only for his permission to make use of his figures 

 in my more detailed papers in my Annual Eeports for 1893, 

 1894, and 1896, but also for being so very good as to identify 

 for me all the specimens I sent over, and to assist me with 

 valuable instruction as to the anatomical and structural 

 formation of Phijtopti. 



Those who wish to study the most recent publications on 

 Phytoptal observation in Austria, Italy, or France, ^>'ill find 

 a list of these in the ' Katalog der bisher beschrieben Gall- 

 Milben ihrer Gallen und Nahrpflanzen, nebst Angabe der 

 einschliigigen Literatur und kritischen Zusatzen.' Zusam- 

 mengestalt von Prof. Dr. Alfred Nalepa, in Linz-u.-Donau. 

 Abdruck aus der Zoologischen Jahrbuchern (Gustav Fischer, 

 in Jena). 



The publications by Dr. Nalepa, from which I have quoted 

 in the preceding paper, are : the ' Beitriige z. Syst. d. Phyt., 

 Sitzgsb.,' 1889, 98 = 'Beitriige zur Systematik der Phytopten, 

 in Sitzungsber. d. Kais. Akad. d. Wiss. in Wien,' 1889. 

 Bd. 98, 1, 1889; also, 'Zur Syst. d. Phyt. Sitzgsb.,' 1890, 

 99=' Zur Systematik der Phytopten, in Sitzungsber. d. Kais. 

 Akad. d. Wiss. in Wien,' 1890. Bd. 99, 1. 



The first-mentioned in the two above paragraphs are separ- 

 ate impressions from the Eeports of the Imperial Natural 

 History Society of Vienna, to which the reference follows 

 each title, and I give both references, as the cost of the 

 pamphlets — 3s. 6d. or thereabouts — is very considerably less 

 than that of the volumes of the Reports or Transactions of 

 the Imperial Society. — E. A. 0. 



Wood Leopard Moth. Zeuzera asciili, Linn. 



The caterpillars of this moth feed in the live wood of many 

 kinds of trees. They are to be found in Pear, Apple, Plum, 

 and Walnut; also in Ash, Beech, Birch, Elm, Holly, Lime, 

 Oak, and others, besides Horse Chestnut {^■Esculus hippocas- 

 tanum), from which the moth takes its specific name, though 

 not appropriately, as it rarely attacks this tree.
