 A lilac tinted ^ specimen of Plebeim agon, taken at Oxshott, 

 July 4th, 1915. 

 Mr. F. H. Stallman exhibited, at the request of Mr. F. W. Fro- 

 hawk, a specimen of Lyaena arion J , to place on record the 

 extremely late date of capture, viz., August 26th, 1915. The 

 previous latest date for capture of the imago known to Mr. Frohawk 

 being August' 15th. The specimen exhibited was taken in North 

 Cornwall by his brother, Mr. E. C. Stallman, and was the only 

 specimen seen during his stay there from August 25th to Septem- 

 ber 1st. It is to be noted that the specimen shows no appreciable 

 sign of wear and cannot have been out of pupa for long. 



It was the opinion of members that possibly the larva of this 

 specimen had been an exceptionally slow feeder, and that any off- 

 spring which it might have would inevitably be doomed to succumb 

 as the food-plant of the earlier larval period, thyme, dies early in 

 the autumn. 



Mr. R. Adkin exhibited a melanic specimen of Thera variata 

 {obeliscata) which he found at rest on the frame work of a window 

 in his house at Lewisham, where it had no doubt been attracted to 

 light, on June 8th, 1915. The specimen was fully as dark as the 

 melanic Paisley race, and showed great contrast with the forms 

 commonly found in the Kent and Surrey pine woods, specimens of 

 which were shown for comparison. He said that the only coniferous 

 trees of which he was aware in the neighbourhood of his house were 

 a few isolated examples of foreign species that were grown in 

 adjacent gardens for ornamental purposes. 



It was remarked that a melanic form of the same species had 

 been reported from Eltham, taken in a garden among fir trees, and 

 that at Finchley, where fir trees were existent in numerous gardens, 

 etc., T. variata (obdiscata), Seiniothisa litiirata, and Ellopia prosa- 

 piaria [fasciaria) had been met with.
