tended diagnosis, to which is appended the word " Koch," thus indicating pretty 

 clearly that these diagnoses were written by C. L. Koch, and not by Herrich-Schaffer. 

 Two new genera are also indicated, viz., Paidium, Koch (p. 356), and Blax, Koch 

 (p. 359) ; the former is in " Scuddor " but dated 1845, the latter is not to be found 

 there. 



I have not paid much special attention to CoUembola, but I do not remember 

 to have seen this little work by Fiirnrohr quoted in connection with them, and this 

 is my excuse for calling attention to it, for it seems practically unknown in this 

 country. — E. McLachlan, Lewisham, London : July Ath, 1900. 



A Supplementary Catalogue of the Library of the Entomological Society of 

 London. — This supplementary Catalogue is now in the press, and is likely to appear 

 shortly. The chief Catalogue was published in 1893. Since then the additions in 

 the ordinary course of events have been large, and there have been what may be 

 termed extraordinary additions, by far the chief of which is the valuable and ex- 

 tensive collection of books and pamphlets bequeathed to the Society by the late 

 Sirs. Stainton, each item of which will be distinguished by an appended letter S. 

 The main Catalogue of 1893 carried an appendix of 20 pages, on which are detailed 

 the additions which came in too late for incorporation in the body of the book. In 

 the supplementary Catalogue these titles will be intercalated amongst the more 

 recent additions, so as to avoid the necessity of multiple reference. A certain 

 number of copies of the chief Catalogue remain in sheets unbound. It is proposed 

 to bind these up with the supplementary C'atalogue, so as to form one volume, which 

 will be appreciated by those who do not already possess the principal Catalogue. 

 The price to Fellows will be very low, the cost being principally defrayed from 

 certain Life Compositions that have been allowed to accumulate for that purpose. 

 All information concerning the Catalogue can be obtained from Mr. Hall, the 

 Resident Librarian. — Eds.

The Injurious Scale Insects and Mealy Bugs of the Beitish Isles : 

 by R. Newstead, F.E.S. Pp. 44, royal 8vo, with many half-tone blocks in text. 

 Forming pp. 219 — 262 of vol. xxiii of the Journal of the Royal Horticultural 

 Society. August, 1900. 



The subject matter of this very useful article in a condensed form was delivered 

 by the author as a lecture at one of the Meetings of the R. H. S. about a year ago. 

 He was the right man in the right place. His knowledge of his subject is undis- 

 puted, and his early training enabled him to combine the professed horticulturist 

 and the skilled entomologist in a manner that has rarely been done in this country. 

 Tlie various divisions and genera of British CoccidfB are passed in review, almost 

 everything of importance being illustrated by photographic figures from life, which 

 mostly come out very well considering the difficulty of the subject. By " British " 

 species is intended those species now known to be injurious in these islands : what 

 the origin of some of the worst of these posts was can only be conjectured. Several 

 of them came to the fore during the present generation. In describing their habits 

 the author's language is clear and unequivocal, and it is rare that any statement is
