234 THE ENTOMOLOGIST. 



B. H. Crabtree read a paper : — " Some Butterflies of the Ehone 

 Valley." During July, 1912, he visited Chamonix, Zermatt, and 

 Berisal, and took between fifty and sixty species, specimens of most 

 of which were exhibited. The species of the genera Lycana, Colzas, 

 Parnassius, Erehia, &c., were particularly noteworthy. — Mr. J. H. 

 Watson exhibited Ornithoptera priarmis (male and female) and 

 0. paradisea, and an example of 0. cVurvilUana. He also showed 

 Papilio laglaizei and a moth which mimics it in a most remarkable 

 manner — Alcides agathyrsus. — -Mr. W. Mansbridge showed Tortrix 

 costana with var. latiorana, from the Liverpool district, and var. nov. 

 Uverana, taken by himself at Liverpool, and by Mr. A. E. Wright at 

 Burnley. He showed also Amphidasys hetularia, from Simonswood, 

 Lancashire, an intermediate form between the type and var. double- 

 dayaria. — Mr. R. Tait, Jr., recorded the capture, by Mr. W. A. 

 Tyerman, of DasypoUa templi, in Oldham Road, Manchester, on 

 February 5th, 1912.— A. W. Boyd, M.A., Hon. Secretary. 



REGENT LITERATURE. 



Forty-second Annual Beport of the Entomological Society of Ontai'io, 

 1911. (Published by Ontario Department of Agriculture, 1912.) 

 This report, consisting of one- hundred and fourteen pages with a 

 number of illustrations, relates chiefly to useful and injurious 

 insects. One or two short papers are of a more general nature, 

 including one on " Insect Migration at Aweme, Manitoba." A dis- 

 cussion on the " Catalogue of Canadian Insects," to be at once 

 undertaken, will be found of interest. WIT 



The Early Stages of our Dragonfiies.-'' By W. J. Lucas, B.A., F.E.S. 



We have now received a print of the very interesting address 

 which Mr. Lucas presented to the Lancashire and Cheshire Entomo- 

 logical Society at their last Annual Meeting. A brief summary of 

 the address was embodied in the account of that meeting which 

 appeared in the ' Entomologist ' for February last, but we find that 

 Mr. Lucas was there wrongly reported to have drawn " particular 

 attention to the habit Ischnura elegans possesses of descending 

 beneath the surface of the water" for the purpose of oviposition. 

 The species really referred to was, of course, Enallagma cyathigerum, 

 and on one or two occasions we have ourselves witnessed the same 

 insect engaged in subaqueous oviposition. 



Mr. Lucas traces in some detail the progress of our knowledge of 

 dragonfly nymphs, but he seems to regard Moufet's ' Insectorum 

 Theatrum ' (1634) as containing the earliest reference to them. 

 According to some other bibliographies which we have seen, how- 

 ever, the literature of the subject begins with the writings of 

 Rondelet (1555) and Aldrovand (1618). At the present time, Mr. 

 Lucas says, " leaving out Sympetrum vulgatum, S. fonscolombii, and
