188 ' [January, 



Mr. W. F. Kirby exhibited, for the Rev. Dr. Walker, a variety of the female of 

 Ornithoptera Broolciana ; he also exhibited, for Major Partridge, an undetermined 

 species of the genus Hadena, captured last summer in the Isle of Portland. 



Mr. R. South exhibited a series of specimens of Tortrix piceana, L., from a 

 pine wood in Surrey ; also melanic forms of Tortrix Podana, S., from St. John's 

 Wood. 



Prof. Meldola exhibited, for Dr. Laver, a melanic specimen of Catocala nupta, 

 taken last September at Colchester. 



Mr. E. B. Poulton exhibited preserved larvae of Sphinx convolvuli, showing the 

 extreme dark and light forms. 



Mr. McLachlan called attention to a plate, representing species of the genus 

 Agrotis, executed by photography, illustrating a memoir by Dr. Max Standfuss, in 

 the Correspondenz-Blatt, Verein " Iris," in Dresden, 1888. He considered it was 

 the best example of photography as adapted to entomological purposes he had ever 

 seen, especially as regarded its stereoscopic effect. 



The Eev. Canon Fowler exhibited a specimen of Mycterus curculionoides, L., 

 sent to him by Mr. Olliff, and taken by Mr. G-unning near Oxford about 1882. 



Mr. W. Nicholson exhibited several melanic varieties of Argynnis Niobe and 

 A. Pales, collected by himself last summer in the Engadine. 



Mr. J. H. Leech exhibited a small collection of Lepidoptera formed last year by 

 Mr. Pratt at Kiukiang, Central China. It included several new species, also speci- 

 mens of a variety of Papilio Sarpedon and other interesting fonns. 



Mons. A. Wailly exhibited a collection of Lepidoptera lately received from 

 Assam, containing upwards of thirty-five species of Papilio, Ornithoptera, Charaxes, 

 Diadema, Cyrestis, and other genera. 



Mr. Meyer-Darcis exhibited specimens of Sternocera tricolor, Ke?r., and S. 



variabilis, Kerr., from Lake Tanganyika ; also two new species of Julodis from Syria. 



Mr. F. Merrifield exhibited, and made remarks on, a long series of Selenia illus- 



traria, S. illunaria, and E. alniaria, in illustration of his paper on " Pedigree 



Moth-breeding." 



Lord Walsingham exhibited, and made remarks on, a series of species repre- 

 senting the genera Snellenia, Wlsm., (Ede?natopoda,-Z., and Eretmocera,.Z. 



The Rev. T. A. Marshall communicated a paper, entitled, " A Monograph of 

 British Praconidce. Part III." 



The Rev. Dr. Walker communicated a paper, entitled, "Description of a variety 

 of the female of Ornithoptera Brookiana." 



Lord Walsingham read a paper, entitled, " A Monograph of the genera con- 

 necting Tincegeria, Wlk., with Eretinocera, Z." A discussion ensued, in which Mr. 

 Stainton, Dr. Sharp, and others took part. 



Mr. Merrifield read a paper, entitled, " Incidental Observations in Pedigree 

 Moth-breeding." This paper contained a detailed account of experiments with 

 Selenia illustraria, S. illunaria, and E. alniaria, which, so far as they had yet 

 proceeded, indicated that retardation of development in the growing stages of the 

 larvae, as well as in the pupal stage, was the cause of the darkening of colour in the 

 perfect insects ; that a low temperature had the effect of causing such retardation ; 

 and that growing the larvae at a forcing temperature tended to produce a wanner; 

 and yellower tint in the colouring of the moths. Lord Walsingham, Mr. Poulton, 

 Prof. Meldola, Mr. White, and Mr. Merrifield took part in the discussion which 

 ensued. 



Mr. J. H. Leech read a paper "On a small collection of Lepidoptera- from 

 Kiukiang." Mr. Elwes said he had examined this collection with very great interest, 

 and was struck with the similarity of many of the species to those from Sikkim. —
