278 THE entomologist's eecord. 



only of systematists, but of economic workers, on account of the decided 

 economic interest attached to most thrips. Brief hints are given for 

 the collection and preservation of specimens, followed by keys of the 

 North American genera and species. The catalogue gives references, 

 habitats and foodplants where known, of 112 species (or including 

 subspecies, 118), falling into 40 genera, and includes description of two 

 genera, ten species, and one variety. LiDiothrips avenae, Hinds, is 

 recognised as the older cercaliiDii of Haliday, but the grass thrips, 

 Anaij/iot/tn'/is striafiis, Osborn, which we have shown to be synonymous 

 with the European form ohscnnts, MiilL, is retained under the American 

 name. A genus and species, h'haj)t<)tliiii)s iwctdiaris, Crawford, must 

 be deleted, having been erected on the strength of a single example, 

 which is evidently the larval form of an Idolothripid (!), whilst of the 

 new forms, l'"Hthn'/>s parvufi, Moulton, becomes a synonym of hUtthrips 

 loni/ipouiis, Bagnall. 



The bibliography is a small one, dealing with notes on North 

 American forms, and dating from 1902. A useful index concludes 

 the catalogue, and the figures, comprised in six plates, are well 

 executed, and characteristic of Mr. Moulton's work. 



Briefly, this publication is a helpful one, and not only does credit 

 to the author and the growing group of North American Thysanop- 

 terists, but is an excellent illustration of the activity and of the 

 up-to-date methods of the Entomological Bureau of the United States 

 Department of Agriculture — methods which might profitably be more 

 energetically followed up or adopted by the old country in the control 

 of her insect pests. — R. S. B. 



Proceedings of the South London Entomological and Natural 

 History Society, 1910-11 {ivitli nine plates.) Price 4s. 6d. — The present 

 volume shows no signs of a falling away from the high standard this 

 Society has maintained for some years. It is, indeed, remarkable 

 that any purely local Society with a small membership should be able 

 to publish so full and valuable a record of its year's work. The 

 solution of the mystery is to be found in the fact that in addition to 

 good workers for science, the membership includes men who are 

 willing to supplement their subscriptions by generous donations to 

 the Publication Fund, and others who give their time to the worthy 

 production of the volume. In addition to a full record of the meetings 

 and the exhibits made thereat, there are several papers of considerable 

 interest printed in e-rknuo with admirable illustrative plates where 

 necessary. The Presidential Address, by Mr. W. J. Kaye, F.E.S., is 

 concerned mainly with a discussion of the classificatory value of the 

 various systems of neuration in Lepidoptera. Mr. W. J. Lucas, 

 B.A., P.E.S., tells how and why the old order Neuroptera has been 

 broken up, and deals more fully with all the families of the order as 

 at present restricted. A couple of fine plates give typical examples 

 of the ten Families into which it is divided. Dr. Chapman contributes 

 a valuable paper on Insect Teratology, also with two plates, and 

 describes a number of interesting experiments tending to throw light 

 on various aberrations from the normal. Mr. R. Adkin, F.E.S., gives 

 the record, kept during a great number of years, of the Lepidoptera 

 affecting one London garden ; and also has an extended note on 

 hlepiolus liumuli and its Shetland forms. Mr. A. Sich, F.E.S., 

 furnishes papers on larval legs and the Middlesex home of t'lauailia
