(Nicotiana affinis) on Sept. 6tli near Bowness. LarvaB of Cucullia aster is 

 had almost all pupated by that date, but larvas of Drepana falcataria and 

 D. iacertula had been very abundant throughout September. Messrs. 

 Duncan, Watson, and Wilkes also made interesting exhibits. — A. M.

OBITUARY. 



Dr. Alexander Wallace died on October 1st, at his residence, 

 St. John's Terrace, Colchester, aged seventy years. He was born in 

 Guilford Street, Russell Square, London, and was educated at Win- 

 chester and Trinity College, Oxford, where he graduated M.A. Having 

 passed through St. Bartholomew's Hospital with distinction and taken 

 the M.D. degree, he held several appointments in London, and subse- 

 quently removed to Colchester, where for a period of about thirty years 

 he practised as a consulting physician. 



Dr. Wallace was at one time an ardent collector of British Lepi- 

 doptera, and was one of the first, if not actually the first, to take 

 British examples of Catephia alchymista, Micra parva, Xola centonalis, 

 Caradrina exigua, and some other rare species ; and there are many 

 notes from his pen in the older entomological magazines. He was a 

 member of the Entomological Society of London for some twenty 

 years, dating from 1858, and it is in the 'Transactions' of that Society 

 that the most important of his papers on sericiculture, a subject which 

 greatly interested him, and upon which he was an authority, are pub- 

 lished. In the 'Entomologist's Annual' for 1869 there is a lengthy 

 article by him on the rise and progress of silkworm culture (other than 

 Bornbyx »«»i) in Europe, with especial reference to the British intro- 

 duction and acclimatization of the then new silk-producing species. 



OUR INDEX. 



In view of the requirements of students of the present day, 

 it seems desirable that reference to the contents of entomological 

 periodicals should be made as convenient as possible. The index 

 of the volume of the 'Entomologist' for 1899 has therefore been 

 prepared on a model different to that of any previous volume of 

 this Journal. Instead of indexing the less common species only, 

 as has been the custom in the past, we have now registered every 

 species alluded to in our pages for the year, the species being 

 entered alphabetically under proper headings. 



We take this opportunity of expressing our grateful thanks 

 to Messrs. Kirkaldy and Lucas for assisting us in this matter. 

 The former has been good enough to undertake the Diptera, 

 Hymenoptera, and Ehynchota ; whilst the latter has kindly 

 attended to the Neuroptera and Orthoptera. 



It is to be hoped that the new departure will prove useful to 

 our readers.
