ISS [August. 



which it is understood that a considerable list was compiled) had been 

 published, it would have been, to me, a welcome and useful instalment. 

 Further, it was, I believe, hoped that similar work would have been 

 done for the Metropolitan Counties north of the Thames ; and so far 

 as Middlesex is concerned, a useful " preliminary " list was published 

 by Mr. T. D. A. Cockerell in the " Entomologist," 1891—2 ; but so 

 far as I know there is not in existence a collected record of the 

 Lepidoptera of the London suburbs before the rapid disappearance of 

 these insects, which has characterized the last few years, commenced ■ 

 Yet Mr. S. T. Klein's catalogue of 130 species taken in thirty-six 

 hours at Willesden, Middlesex, ought to have stimulated some one to 

 follow up the theme in so rich a district. 



For Harrow, in the same county, a list of 469 species has just 

 been drawn up, with great care, by Messrs. J. L. Bonhote and N. C. 

 Rothschild. Two or three of the species would seem to require con- 

 firmation by strong evidence, but, as a rule, great accuracy has 

 evidently been attained, the unusual course being taken of furnishing 

 the names of the captors for even the most abundant species. Intended, 

 as it is, as a guide and sort of Manual for the boys of the Harrow 

 School, much information is incorporated as to species not found in 

 the district, and carefully drawn-up tables of the species in the larger 

 genera are furnished ; the list being also extended beyond the ordinary 

 Macro-Lepidoptera to include the Pyralides, Crambina, and Pteropho- 

 rina. Whether the Harrow School collectors are such complete 

 neophytes as to require an E^iglish name, however unsuitable, for every 

 species, is a question which the authors, as " old boys," should be best 

 able to answer. 



For the county of Kent I know of no general catalogue. A list 

 of over 500 species, extending to the Phyciiidce, occurring in the 

 Rochester and Chatham districts, was contributed to the "Rochester 

 Naturalist " by Mr. W. Chaney in the years 1884 to 1888. It is care- 

 fully drawn up, with notes of localities, dates and habits, and apparently 

 very accurate. 



Previously to this my old friend Dr. H. G. Knaggs had, in 1870, 

 published a list of the " Macro-Lepidoptera of the neighbourhood of 

 Folkestone" in the same count}'^, for the Folkestone Natural History 

 Society. This list, extending to over 400 species, is full of notes upon 

 the habits and times of appearance of the species, and of great value. 

 It also contains notices of a few Micro-Lepidoptera. 



Besides these I have a MS, list by Mr. J. J. AValker of nearly 

 400 species found by him in the Isle of Sheppey, including, besides
