162 THE entomologtst's record. 



in parts and quite empty ; further, " the parts of the nervures where 

 the segments unite seem to be sohd, somewhat resembling the joints of 

 a bamboo-cane, which would make the passing of the fluid through 

 them almost, if not quite, impossible." Mr. ]\Ioffatt's impression is, that 

 " the nervures do not in any measure contribute towards the extension 

 of the wing, l)ut depend for their own extension on the pressure 

 derived from the fluid flowing between the membranes." 



An examination of the wing of a specimen of Anosia arch'ppus, 

 which had matured up to the point of emerging but had died before 

 accomplishing the change, enal)led Mr. Moffatt to give the following 

 interesting description of its structure. " I removed the costal nervure, 

 and when examining the cut edge with a lens I perceived in one place 

 that the edges of the membranes had parted. By many efforts and 

 steady directing I succeeded in getting the point of a pin between 

 them, when I found that the winglet was like an empty sac. The two 

 membranes were not in the least attached ; even at the edges there 

 was no pressure required to sej^arate them, and the only thing that 

 showed any symptom of holding them together was the fringes ; so I 

 separated the two membranes clean from base to apex without an 

 efi:'ort, when the whole structure of the winglet was exposed to view. 

 The nervures are in the up])er membrane, with a groove in the lower, 

 opposite, into which they fit." The paper also contains some highly 

 interesting and suggestive remarks on the physiological way in Avhich 

 the colouring matters enter the scales. 



There is a long and somewhat exhaustive paper on " The Gipsy 

 Moth (Ocneria dispnr)" by J. Fletcher, of Ottawa, in which he goes 

 over the ground of its probable introduction, its rapid spread in 

 America, and the damage it has already done. Some fifty ]3ages of 

 economic entomological matter and two photographs — of Professor 

 W. Saunders, F.R.S.C, an old Grediton boy, and of A. R. Grote, A.M., 

 an old Lancashire lad we believe — complete a most interesting and 

 readable little volume. As the Report is published by the government, 

 a note to Mr. Moffatt, Librarian of Ent. Soc. Ontario, Victoria Hall, 

 London, Ontario, with but little more tlian sufficient money to cover 

 postage will, I doubt not, be sure to obtain it. It is also in the 

 libraries of the Ent. Socy. of London and the City of London Ent. 

 Society. 



Entomologisk Tibskrift, 1894. — [Published by the Entomological 

 Society of Stockholm]. — This volume contains a number of very in- 

 teresting contributions. Sven Lampa writes several papers on economic 

 entomology, dealing, amongst others, with several well-known British 

 species. A paper (written in English) on the remarkable Hemimerus 

 talpoides, which Saussure brought to the knowledge of naturalists, is 

 exti'emely interesting, and the writer, L)r. Hansen, after chapters 

 entitled " Introductory Remarks," " Description," " Propagation," 

 " Occurrence and Biology," " Literature on the subject," finishes with a 

 short chapter on " The systematic position of Hemimerus," in which he 

 concludes that " Hemimerus most decidedly belongs to the Orthoj^tera," 

 and that it constitutes " a separate family very closely allied to the 

 family Forficulidae." A paper on the geographical distribution of cer- 

 tain Lepidoptera in Sweden, by J. Meves, includes Chrysojihanus phloeas 

 var. americana, Melitaea athalia var. parthenoides, Spilosnma tirticae, 

 Notodonta tritophus, Cymatophora flavicorw's ab. unimacidata, Agrotis
