144 THE entomologist's record. 



He describes a number of valuable experiments he had made with 

 certain of these insects in his observation nests. These notes are a 

 further testimony to the thorough and praiseworthy manner in which 

 Mr. Donisthorpe is tackling this important problem as to the relation 

 between ants and the dwellers in their nests. 



The only other article to which I need refer is Dr. Longstafi's 

 account of three weeks in the Sudan (Ent. Mo. Mag., xlvii., pp. 119 

 and 194). Though Dr. Longsta£f paid but little attention to the 

 Coleoptera, he has given some interesting notes as to some of the 

 more striking species which occur in the neighbourhood of Khartum 

 and the surrounding country. Mr. G. A. K. Marshall has described 

 {J,oc. cit., p. 207) a new species of Baris under the name of lorata, from 

 the Sudan. 



Two parts of the Transactions of the Entoiiwhuiical Society of London 

 for 1911 have been issued up to the close of the year. In Part II. 

 there are two papers dealing with Coleoptera. The first, illustrated by 

 two plates, one of them coloured, is by M. Henri Boileau ; it contains 

 descriptions of several new species of Lucanidae in the British Museum 

 collections. Tv/o species oi Sphenof/nathus from Bolivia; two species 

 of Lncaniis from Burmah and Assam respectively; one species of 

 Rhaetidiis from Siam ; two species of Hemisodorcas from Perak and 

 Burmah respectively ; one species of Gnaphaloryx from Sumatra ; and 

 two species of Niyidius from Rangoon and East Africa respectively are 

 described. Both the species of Sphenonnathua and of Lucanus as well 

 as the species of Rhaetuliis are well figured in the two plates. 



The second paper is by Mr. E. A. Elliott and Mr. C. Morley and is 

 entitled " On the Hymenopterous Parasites of Coleoptera. First 

 Supplement." Since the publication of their original paper in the 

 'Tramactions in 1907, much additional matter has come to the 

 knowledge of the authors ; this paper contains this additional matter. 

 It should be read in conjunction with the original paper, with which 

 it is uniform and concurrently numbered. The paper embodies the 

 results of most painstaking investigations through the works of a 

 number of well-known entomologists, and brings together mto a 

 convenient form for reference a mass of field and other records hitherto 

 scattered throughout the pages of the numerous works which the 

 authors have consulted. The thanks of all entomologists are due to 

 the authors for their labours, and for the clear and admirable way in 

 which they have arranged the records so as to facilitate future reference. 



Excellent progress continues to be made with the Coleopterormn 

 Cataloyiis edited by Schenkling, and published by Herr Junk. Parts 

 25-38 were issued during the year, and Part 39 has just come to hand. 

 The following families amongst others have been dealt with : — 

 Pselaphidae ; Tenebrionidac, 3rd and 4th sections ; Staphijlinidae, 2 

 sections; Ciasidae ; (Virysomelidae-IJispinae : Anthicidae : IScarabeidae- 

 Coprinae, 1 ; Cera})ib]icidae-Cera)nhiicinae. 



Professor Blatchley, of Indianopolis, U.S.A., has published what he 

 calls An illustrated descriptive cataloi/iie of the Coleoptera or beetles 

 [exclusive of the lUnjucofthora) known to occur in Indiana: it is, however, 

 a treatise extending to 138H pages, illustrated with 590 figures of the 

 more important species (2535 are dealt with), and with many diagrams 

 of structural details ; this volume is another illustration of the 

 thorough way in which our American cousins are dealing with the 

 Natural History of their great country.
