218 Address delivered at the sixth and last 



restoration of our native timber, when exposed to the ravages 

 of a destructive insect. In the present notice he has been 

 equally successful in detecting the cause of disease, and sug- 

 gesting the remedy for it, in a fruit that forms a considerable 

 branch of commerce. It comes not within the province of 

 your chairman, when reverting to the labours of past years, 

 to allude to the promises of the future. But I cannot 

 avoid anticipating a little on this occasion, by stating what, I 

 know, will be heard with the greatest interest by my friends 

 around me, that I have already received, from our colleague 

 at the Havana, the commencement of a series of entomolo- 

 gical papers, intended as a sequel to the invaluable Horce 

 E7itomol6gicce. 



It is one of the great merits of the friend of whom I have 

 just spoken, that he has opened to others the path which he 

 has himself so successfully trodden. Dr. Horsfield, following 

 his footsteps, has not failed to imbibe a portion of his spirit. 

 In his work on the Lepidopterous insects of Java, of which a 

 second part has appeared within this year, our valued col- 

 league has given us the opportunity of remarking a union of 

 characters seldom found in an individual, — and which he, 

 shares in common, perhaps, only with the individual just 

 alluded to, — a comprehensiveness of views, accompanied by 

 a minuteness and finished accuracy of detail. We are indebted, 

 likewise, to Dr. Horsfield for a description, in the Zoological 

 Journal, of some new species of Oriental Lepidoptera, which 

 did not form part of the collection at the India House, and 

 consequently did not come regularly into his greater work. 



Our colleague, Mr. Westwood, whom it is the boast of this 

 club to have enlisted into science, and to rank among its most 

 able recruits, has, during the last year, exhibited to our 

 meetings, and commented upon, several new and interesting 

 Coleopterous insects belonging to the families of Cicindelidae, 

 Notoxidae, and iampyridae. His observations will appear in 

 the forthcoming number of the Zoological Journal, Dr. Heine- 

 ken of Madeira has, during the same period, favoured us with 

 many interesting observations on various Annulose animals, 

 particularly on the habits of some species of the ^rachnida. 

 Mr. Thomson, likewise, has continued his Zoological Illustra- 

 tions, in which he has given descriptions of some of the lumi- 

 nous animals among the Crustacea; and has, at the same 

 time, added to the information previously communicated by 

 him, respecting the metamorphosis of that group. And Dr. 

 Johnston of Berwick, in his Co7itrihutions to the British Fauna, 

 has also, with much ability, observed upon some Crustaceous 

 species.
