noise-producing organs, there can be no doubt they also have the 

 sense of hearing. Fresh fields for investigation open at every point, 

 and the subject is one of interest and profit. The paper was followed 

 by a short discussion. Microscopical slides dealing with entomo- 

 logical subjects were shown by Messrs. S. Taylor, R. Brauer, W. 

 Buckley, and E. C. Stump. A number of preserved larv.ne were dis- 

 tributed by Mr. W. Warren Kinsey. — Robert J. Wigelswokth, Hon.

EECENT LITERATURE. 



A List nf Yorkshire Lepidoptera. By George T. Porritt, F.L.S., F.E.S. 

 (Trans. Yorks. Nat. Union). 8vo, pp. i-xvi and 193-269. 

 London : A. Brown & Sons. 1904. 



A Supplement to the List of Yorkshire Lepidoptera, published in 

 1883, by same author. It contains fifty-three species not found in the 

 first edition ; of these seventeen are Tortrices and eighteen Tineas. 

 Fifteen species which. were included in the former list are now with- 

 drawn. The total number of species for the county is given as 1379. 



The author's remarks on Melanism, in the preface, are of consider- 

 able interest. He mentions twenty-nine species of which black or 

 nearly black examples are of regular occurrence in particular districts 

 in Yorkshire, and, referring to a number of other species, he states that 

 " specimens so much darker than the typical forms are so frequently 

 taken as to indicate that they too are gradually being influenced 

 towards the same end." 



The list is a valuable addition to faunistic literature.

Among other items, this modest little volume contains short papers 

 on holiday collecting at Dawlish, and the reports of field-meetings of 

 the Society held during the year 1903. A chart, or map, accom- 

 panying Mr. Robert Adkin's account of the excursion to Limpsfield is 

 especially interesting, as it not only indicates the route taken by the 

 party on that particular occasion, but it will also be exceedingly useful 

 to anyone wishing to further explore the district. 



In the Presidential Address, Mr. Edward Step, F.L.S., gives a 

 resume of the year's additions to the British Fauna Lists, and also 

 touches on the subject of the tsetse-flies and their association with the 

 African " sleeping sickness." 



The reports of the meetings of the Society occupy over forty pages, 

 and afford much interesting reading, 



Obituary. — With much regret we have to announce the death of 

 Mr. Robert McLachlan, F.R.S., &c. A further notice will appear in 

 the July issue.
