284 THE ENTOMOLOGIST. 



of cases. In a few species the genitalia appear to be in a plastic 

 condition, and considerable variations are found, such as in the 

 case of Epiblema pflugiana, which is apparently divided into several 

 distinct forms, but the genitalia give no constant character by which 

 to separate them. 



On looking through the lists of species certain points strike us. 

 We should have liked to see more synonymy in some cases. On p. 10, 

 for instance, Cnephasia incertana Tr. appears without its perhaps 

 better-known synonym, G. subjectana Gn. ; on p. 11 C. longana 

 Haw. is similarly treated, without reference to its other name, 

 C. ictericana Haw. There are several other instances in which we 

 should have been glad to have the old, better-known names indicated. 



On p. xxi of the introduction we are told that the author cannot 

 distinguish between the genitalia of Argyroploce carbonana and 

 A. nigricostana, but on p. 46 we see A. carbonana Dbl.=?istulana 

 Ha,w.=fuMgana Barrett, and on p. 47 that it is the A. fuligana of 

 Hubner of which the synonym is carbonana Barrett, which has 

 genitalia not distinguishable from A. nigricostana Haw. 



The book is one all students of the Order, and all philosophic 

 entomologists, should possess ; and we trust for the sake of the author 

 who has produced it in these very expensive times, for pure love of 

 science, that everyone who can possibly afford the cost will take a 

 copy. It is to be obtained from Mr. F. N. Pierce, The Old Eectory, 

 Warmington, Northants ; and the price to subcribers, including 

 postage, is 15s. M. per copy. . W. G. S. 



In Bulletin, No. 1 (Technical Section) of the Sultanic Agricultural 

 Society, Cairo, pp. 12, 13, (1922), Mr. F. C. Willcocks gives a table 

 of results of some moth-trap experiments using different coloured 

 lights. Assuming all the lamps to have been used an equal number 

 of times, the numbers of moths caught were : at blue light, 335 ; 

 white, 297; green, 67; orange, 38; red, 37. In view of recent 

 discussions in this magazine it is interesting to note that blue 

 light was more attractive than white. The experiments were in 

 connection with economic work, and a fuller report is promised 

 lat er. N. D. E. 



Seitz, MacroUpidoptera of the World, publication of which was 

 interrupted to some extent by the war, appears now to be on a 

 sound footing again. The Palsearctic Division is complete and the 

 Bhopalocera volumes at least of the other Division are going on well. 

 In the German edition the Hesperidas have been reached in the 

 American, the Lycaenidae in the Indo-Australian and African 

 sections. With the moths matters are unfortunately not so 

 advanced, but progress is certainly being made. The English 

 edition naturally lags behind the German to some extent, but is 

 gradually overtaking the arrears. Herren Seitz and Kernen are to be 

 congratulated on the success which is attending their determined 

 efforts to overcome the many difficulties with which violently 

 altered circumstances have surrounded their undertaking. At the 

 present rate another year or two should see the welcome conclusion 

 of this very valuable work. N D E
