viously in the Society's possession. It was announced that the 

 following gentlemen were elected as Officers and Council for 1899 : — 

 President, Mr. G. H. Verrall ; Treasurer, Mr. R. McLachlan, F.R.S. ; 

 Secretaries, Mr. J. J. Walker and Mr. C. J. Gahan ; Librarian, Mr. 

 G. C. Champion ; and as other Members of Council, Mr. W. F. H. 

 Blandford, Dr. T. A. Chapman, Mr. H. St. J. K. Donisthorpe, the Rev. 

 Canon W. W. Fowler, Mr. A. H. Jones, Mr. F. Merrifield, Mr. E. 

 Saunders, Mr. R. Trirnen, F.R.S., Mr. J. W. Tutt, and Mr. C. 0. 

 Waterhouse. The Address of the retiring President was then read by 

 the Secretary. In this, after a review of the present position of the 

 Society, an account was given of the various experimental researches 

 and observations made on the subject of seasonal dimorphism in 

 Lepidoptera from those of Weismann down to the evidence recently 

 brought forward by Dr. Dixey on the existence of this phenomenon in 

 Neotropical Pierinae. The Address concluded by the repetition of 

 the recommendation made on the previous occasion — that biological 

 stations should be established in tropical countries for the study of 

 seasonal dimorphism, mimicry, and kindred phenomena. The pro- 

 ceedings terminated with the passing and acknowledgment of votes of 

 thanks to the retiring President and the Officers. 



February 1st. — Mr. George H. Verrall, President, in the chair. 

 The President briefly returned thanks for the honour conferred upon 

 him by his election, and announced that he had nominated the Rev. 

 Canon Fowler, M.A., F.L.S., Mr. Edward Saunders, F.L.S., and 

 Mr. Roland Trimen, F.R.S. , as Vice-Presidents for the session. Mr. 

 Henry William Andrews, of 9, Victoria Road, Eltham, was elected a 

 Fellow of the Society. Mr. Champion exhibited three specimens of an 

 interesting species of Fulgoridae, Atalanta auricoma, Burm., recently 

 received from British Honduras, from M. Blancaneaux ; and stated 

 that he had found lepidopterous larvae in the white waxy matter 

 attached to the body of an allied species, Enchophora stellifer, Burm., 

 in Central America, of which insect he exhibited a specimen, together 

 with a larva taken from it. This larva was very like that of Epipyrops 

 anomala, Westw., a species of Arctiidae which is attached to Fulyora 

 candelaria in a similar way. He also showed numerous specimens of 

 both sexes of an undescribed species of Apiomerus (family Reduviidaa) 

 found by himself in Chiriqui, and pointed out some of the more 

 interesting peculiarities of each sex. Mr. Tutt exhibited, on behalf of 

 the Rev. G. H. Raynor, a large series of Spilosoma lubricipeda, Linn., 

 inbred from specimens originally captured in Lincolnshire. Its chief 

 interest seemed to be its demonstration of the fact that the extreme 

 aberrations of this species could be produced by inbreeding from com- 

 paratively normal forms, a fact of all the more importance considering 

 how much uncertainty there had been as to the real origin of the race 

 which was first sent out from Yorkshire, and is now to be seen in many 

 collections of British insects. He also exhibited, for Mr. Raynor, an 

 aberration of Epinephele tithonus, taken at Hazeleigh in August, 1892, 

 in which the bright fulvous areas were pale yellow in colour ; and a 

 somewhat strange aberration of Noctua rubi which showed considerable 

 difference from the normal form in the arrangement of the transverse 

 lines of the fore wings. Mr. Tutt then exhibited a number of closely- 

 allied forms of Anthrocera, recently received from M. Oberthiir of
