OBITUARY. 
I have had occasion to bring under your notice during the past 
year the losses we have sustained by the death of two eminent 
Members of our Society, on whom appropriate panegyrics were 
delivered by Professor Westwood and Mr. Stainton. 
Dr. Joun Epwarp Gray, who died on the 7th of March last, 
aged seventy-five, had filled the post of Keeper of the Zoological 
Collection in the British Museum since 1840, which post he 
resigned a few months before his death. The vast number of 
papers which have emanated from his pen, and which have borne 
him a rich harvest of renown in the field of Science, are a standing 
record of his indefatigable assiduity; and although his literary 
labours were principally devoted to other branches of Natural 
History, the department of Entomology was indebted to him for 
much effective support in his official capacity; and he occupied 
the Presidential Chair of this Society in 1858 and 1859. 
Henry Dovusuepay, well known as a Lepidopterist of the 
highest repute, died on the 29th of June last, in his sixty-seventh 
year. Notwithstanding his profound acquaintance with that order 
of insects to which he had attached himself from early youth, his _ 
writings have been limited to fragmentary records in various 
periodicals, with the exception of his ‘Synonymic List of British 
Lepidoptera,’ published in 1850, whereby he sought to reconcile 
the many discrepancies between the names then in use among 
Lepidopterists at home and abroad, and to harmonise these dis- 
cordant elements as an essential prelude to international concert. 
He was one of the few remaining original Members of this Society, 
and had lived a retired life for many years past at Epping, where 
he died esteemed and lamented by all who knew him. 
Economic Enromonoey. 
The life-history of the Phylloxera has been already explained 
on a former occasion; and Mr. Riley, the State Entomologist of 
Missouri, whom we had the pleasure to welcome at one of our 
meetings, furnishes a corresponding epitome of the same in his 
Seventh Report for 1875. No inexpensive method of extirpating 
the evil has been found practically available on an extensive scale, 
excepting the process of submersion, where feasible ; but the most 
important results have been obtained by the substitution of certain
