A series of specimens of the teeth at the end of the clasp of 

 P. argils, and also of a number of allied species, showing the 

 great variation of these parts in P. argits, and yet always 

 with characters that made them clearly P. argus, and quite 

 impossible to confound with the other species, whose varia- 

 tion might be equally great, but examples were not avail- 

 able to illustrate this. The specimens were all pressed quite 

 flat, so as to be perfectly comparable. 



SEPTEMBER 22nd, 1910. 



Dr. Chapman exhibited a bred series of the summer 

 brood of Agriades coridon, from the Riviera, together with 

 a few examples of the first (May and April) brood. The 

 summer brood emerged in August. It was stated that the 

 Riviera was practically the only area where this species 

 was double-brooded (see "Trans. Ent. Soc. Lond.," 1910, 

 p. xlvii). 



Mr. West, of Ashtead, exhibited a bred series of Malaco- 

 soma neustria, including very light and very dark specimens 

 of both sexes. It was remarked that occasionally a whole 

 brood would produce dark examples, but that, usually, both 

 very dark and very light forms were well represented. 



Mr. Andrews exhibited a short series of the Dipteron, Pcgo- 

 myia setaria, taken at Chattenden, June iSth, igio ; and also 

 ol Isopogon brcvirostyis, taken at Shoreham, Kent, July 30th, 

 igio. 



Mr. Newman exhibited a specimen of Cclastrina argiohis, 

 female, in which the black border was unusually wide and 

 the fringe spotted: an example of Pachnobia hyperhorea 

 [alpina), in which a radial section of the hind-wing had the 

 richly coloured and variable markings of the fore-wing, the 

 fringe being exceptionally well reproduced ; an orange form 

 of Arctia caja, with only a few dark markings on the fore- 

 wing, forming an imperfect fascia; several varieties of 

 Angcrona pvnnavia, including one very uniform in colour, and 

 another beautifully marbled, and having a wide fascia on the 

 fore-wings only; a ver}' dark male oi Adopaa flava (lincola), 

 and another with xanthic discal patches on all the four wings ; 

 a very dark Lasiocampa qucrcils v. callnna:. A further exhibit 

 was a most extraordinary aberration oi Abraxas grossulariata 

 of the ab. ladicolor form, extremely pale, with but few 

 diminutive dark markings, somewhat black on the costa, a 

 few black dots on the fringe, and several scattered faint
