polytes would continue to be recorded from many parts 

 of its range. It was interesting that P. {Ph.) aristolochiae 

 should be so rare as compared with its mimic ; but it was 

 probable that the proportions would be very different at 

 other times. Two of the male polytes, exhibited to the meet- 

 ing, had probabl}'' been injured by the attacks of birds or 

 lizards. 



Some British Lycaenids. — The Rev. G. Wheeler ex- 

 hibited three small boxes of British Lycaenids, taken in July 

 and early August this year : — 



(1) Polyommatus icarus, Rott., from the Durham coast, 

 remarkable for their large size and the brilliant tint of the 

 o o- 



(2) Plebeius aegon, var. masseyi, Tutt, the form from the 

 northern mosses, the S c? bright blue, with very narrow 

 black border and conspicuous black marginal spots on the 

 hindwing, the $ $ strongly suffused with blue, in most cases 

 as extensively as in Agriades corydon, ab. semisyngraj)ha \ 

 the underside of the ^ ^ was remarkably white ; amongst 

 the latter was an aberration having lead-coloured hindwings 

 on the upperside, and two with some of the spots of the 

 underside striated. 



(3) Aricia medon, Hiifn., from the Durham coast, including 

 almost typical specimens ; var. salinacis, as described by 

 Stephens, the ^ with a black discoidal spot on the upperside 

 of the forewing, the 9 with a white one; ab. similis, Tutt, the 

 J with a white discoidal spot; ab. albiannulata, Harr., with 

 black discoidal ringed with white, so frequently described 

 as var. salmacis, the original description of which excludes 

 this form ; ab. red me, Harr., with its extreme form ab. obsolela, 

 Obth., in which the spots of the forewing are missing on the 

 underside, as well as those of the hindwing; ab. semivedrae, 

 Harr. ; and ab. inclara, Harr., with its silvery-white ground- 

 colour on the underside, this specimen being also somewhat 

 striated. To these were added a few var. artaxerxes, F., from 

 Kinghorn. 



Mr. Wheeler said he had used the name " aegon "' intention- 

 ally, being sure that it was correct, since Linnaeus had used 

 the name coyus for both species, there being a $ aegon among
