140 THE entomologist's record. 



'time, President of the Penarth Entomological and Natural History 

 Society. At the meeting of the Society, held April 20th, he urged the 

 members to collect for the purposes of study, deprecated mere collect- 

 ing, and recommended the members to make careful observations of the 

 animals they studied, under natural conditions. He particularly 

 condemned the careless destruction of rare insects, plants and animals. 

 The society appears to be the only purely entomological society in Wales. 

 We trust that one of its early labours will be the compilation of a 

 fauna of the county of Glamorganshire, if not a fauna of Wales, which 

 is very badly needed at the present moment. 



The 21st livraison of the Ktadex (F Kntoniuloi/ir" has just been 

 published by 'M. C. Oberthiir. It deals with the variation of the two 

 American species lleliconia tliti.riojie and H. resta, with some incidental 

 notes on closely allied species. To those who know the marvellous 

 excellence of these Etnrles one need only say that this volume is quite 

 up to the standard of the preceding ; to those who have not yet studied 

 them we can only say that no better entomological work is produced, 

 the letterpress and plates being alike excellent, and the get-up artistic 

 in the best sense. The large number of coloured figures illustrating 

 the variation of the species discussed, can leave no i-oom for doubt in 

 the student's mind, a statement that can rarely be made of the 

 unillustrated works of many other authors. To all students of the 

 Heliconiids, and to all interested in the general subject of variation, 

 the work will be hailed with pleasure as an excellent summary of the 

 facts relating to the variation of the species treated and so well 

 illustrated. 



Ih-. K. W. Verhoeli' has in two recent papers entirely rearranged 

 tile l''(irjiciilaria, or rather, the Deriiiaptcra, which he adopts as an 

 ordinal name. The first papei', " Uber Dermapteren," appeared in 

 ]\larch last in Xonhiiiisclic Air.ri(/rr, Band xxv., no. 665, p. 181^ 

 followed by a supplemental paper in the Sit^.iiniix-Jiericht tier Ges. 

 vaturf. Frenndc -.ii lii'iiin, 1902, no. 1, p. 7. In these two papers 

 he draws up an entirely new and original scheme of classification for 

 the Drniiaitteya, temporarily postponing Labia and Neolobophora, and 

 a few other obscure genera for farther investigation ; he divides the 

 remainder into Paradfriiiaptcra and Kmlrniiaptcra, the first containing 

 the single family Ajiachi/idai', and the single genus AjiarJn/s, Serville ; 

 the remainder he again divides into two, the Kadt'imaptcra Monandria 

 and the Kuderiitaptcra Diandiia. The species of the latter have the male 

 genital organs in duplicate, and include the families A nisidabidae, Gonola- 

 hidae, Isulabidae, lH/dati/idan, Fj/nidicraiiidai' and Labidnridae. In the 

 Monandria, with a single penis, ditctus ejaculatorius, pi'senuptial sac 

 and virga, he places the Chdiduridae, the Furjiculidar, a new family 

 the Karsv/dellidaf, containing two new genera erected around Pi/(/idi- 

 crana b'uttneri, Karsch. Another new family, the holabidae, falling 

 next in order to the Gonolahidae, contains three new apterous African 

 genera. A few new species are described and several new genera 

 raised. The papers will be discussed in detail next month.
