of facts may probably prove of more lasting interest than the theories deduced from 

 them. This paper must be studied by all workers on the subject. It will be 

 startling to some to read the theoretical assertion (p. 6) that " Micropteryx is more 

 Neuropterous than the Trichoptera are," even if " Trichoptera and Eriocrania are 

 on about the same horizon." Dr. Chapman's paper is followed by another equally 

 or more speculative, by Mr. Tutt, on " The Nature of Metamorphosis." Then comes 

 a short paper by Mr. Scourfield on " Fresh-Water Entomostraca," followed by one 

 on "Orthoptera: with special reference to the British species," by Mr Malcolm 

 Burr, a well written and useful article. The papers end with one by Mr. R. Adkin, 

 being a continuation of his notes on the Lepidoptera, &c., of Eastbourne, in which 

 are included valuable direct observations on an immigration of Pieris rapce. The 

 Address by the President (Mr. A. Harrison, F.L.S., &c.) may be read with both 

 pleasure and profit ; it shows that the writer of it can reason soundly on what he 

 has read. It may bo divided into two parts : the first treating on the somewhat 

 obscure subject " Tclegony," the other on the transmission of malarial fevers by 

 Culicidce, in which the results of the latest experiments are detailed in a succinct 

 and intelligible manner. 



The accounts show that the Society's financial position is sound ; but there is 

 the usual lament that some Members will not satisfy their engagements by paying 

 up — a lament shared by many Societies. 



Although the pnpers published in exfenso are somewhat fewer than is usual, we 

 consider the value of these " Proceedings " as a whole fully equal to the publications 

 of the Society for any former years. We are reminded that this is its 27th Annual 

 Report, and that its numerical strength is 166. 



A List oe the Coleopteea of the Rochester Distbict : by J. J. Walkee, 

 R.N., F.L.S. 



This list, published at intervals in vol. ii of the " Rochester Naturalist," was 

 commenced in July, 1897, and concluded in July, 1900. 1615 species are enu- 

 merated, nearly half of the total number known as British, and with few exceptions 

 all captured by the indefatigable compiler. Copious notes on localities, habits, &c., 

 are given, as well as general remarks on each of the families. The district comprises 

 an area of about 113 square miles, contained within a circle of six miles radius of 

 the L.C.D.R. station at Chatham, in which " we find some of the most charming 

 scenery in Kent, with an endless variety of soil, aspect, and condition of country, 

 as well as a flora of exceptional richness. It includes sand, clay, gravel, and chalk, 

 the latter soil occupying a large portion of its surface ; old and young woods of 

 great extent, dry open flowery hill-sides, pasture, hedgerow, water-meadow, salt- 

 marsh, and river-bank." The total number of species recorded from Norfolk by 

 Mr. Edwards is 1729, and from Suffolk by Mr Morley 1763, as against 1615 from 

 the Rochester district alone, which thus appears to be particularly rich in Coleoptera. 

 The counties of Kent and Surrey together would probably furnish fully 2400 

 species, about 2200 having been noted by me in a list compiled about 25 years 

 ago, and never finished. — G. C. C.
