examination of the genitalia, he had found to be a dwarfed Argyrolepia 

 cnicana ; Mr, Pierce also gave some critical notes on Ephestia 

 elutella and E. passtdella. He was followed by Mr. W. Mansbndge, 

 who exhibited the latter species in illustration of his remr ' 'Ir. 

 S. P. Doudney had a long series of Porthesia siniilis, h- .i-la-rvse 



taken on the same hedgerow at Huyton, near Liv ^^jui, in which 

 many of the females had tail-tufts brown instead of yellow, except 

 for a slight admixture of yellow hairs ; all the males were normal. —

EECENT LITERATURE. 



The Orthoptera of Devon. By C. W. Bracken, B.A., F.E.S. From 

 the ' Transactions of the Devonshire Association for the Ad- 

 vancement of Science, Literature, and Art,' 1916, xlviii, 

 pp. 267-282. 



Not sufficiently often do we see so well worked out a paper on a 

 group of insects belonging to a particular area as is this which 

 Mr. Bracken read Plymouth on July 20th, 1916. Why is it that 

 other counties are not doing in this respect what Lancashire and 

 Cheshire, Yorkshire, and Devon are able to do? Setting out 

 primarily to complete and correct Mr, Parfitt's paper of 1881, 

 Mr. Bracken has eventually given a full, interesting, and eminently 

 readable account of the present state of our knowledge of the 

 Orthoptera of Devon. His nomenclature and arrangement are 

 thoroughly up to date, and he has worked hard for some time to 

 bring the records as far as possible up to date also. As a result he 

 is able to say that nearly all the British species of the order are 

 found in Devon. There is one plate, illustrating the earwig, Aniso- 

 lahis annulipes, Luc, and the locustid, Gonocephalus dorsalis, Latr. 

 We are glad to hear that Mr. Bracken has already attacked another 

 group of Devonshire insects. W. J. L.
