NOTES FROM WEST SUSSEX : LEPIDOPTERA IN 1920. 51 



Augiades sylvanus: — June 9th. Common in many localities, more 

 especially on the Downs. 



Kpinephele jurtina. — June 11th. Common throughout the district. 



Brenthis selene. — June 15th. Very local, but plentiful in two 

 localities only — in a marshy corner of a common near Storrington, and 

 in a heathy hollow on the Downs, near Sompting. I fancy that mem- 

 bers of the latter colony were generally smaller than those found at 

 Storrington. 



Melanaryia galathea. — June 25th. Locally abundant between 

 Steyning and Lancing. A single example, a g , was found at rest as 

 early as June 25th, and on going to the same locality three days later 

 I found plenty more $ s out, but not a single $ could I see. On July 

 2nd, however, both sexes were well out, and it was a pleasing sight to 

 see this handsome butterfly so remarkably abundant. A visit to one 

 of its principal haunts was made on August 11th, when I found a few 

 still on the wing, but getting very worn. With the exception of one 

 yellowish $ , I noticed no great variation. 



Argynnis cydippe. — June 29th. Met with sparingly in the wood- 

 lands near Patching, Angmering, and Storrington. 



Argynnis aglaia. — June 30th. Not very common, but met with 

 on the Downs near Sompting, Lancing, and Edburton. On June 

 30th, near Sompting, I netted a male with the spots inclined to be 

 greenish, which gives to the markings a remarkably soft appearance. 

 Sussex specimens appear to be smaller than our West Somerset race. 



Aphantopus hyperantus. — July 3rd. Locally common, near West 

 Grinstead, Storrington, and Angmering. 



Epinephele tithonus. — July 9th. Plentiful in most parts of the 

 district, but, apparently, not very variable. 



Agriades coridon. — July 9th. Locally plentiful on the Downs, but 

 disappointing, as I obtained no striking aberrations. It may be worth 

 recording, however, that in a chalk pit near Lancing I met with a few 

 dwarf specimens, and also the following forms were taken : — (i.) A $ , 

 with broad blackish borders on all the wings containing whitish ringed 

 spots, which, on the hindwings, are clearly defined, but less distinct on 

 the forewings. The clouding of the borders also invades the fringes 

 and increases the black chequering, especially towards the apex of the 

 forewings. (ii.) A ? , strongly powdered with blue scales within and 

 below the discal cell on the forewings, and between the veins on the 

 hindwings, forming blue streaks from the base of the wing to the edge 

 of the submarginal spots, the latter being ringed with dull orange, also 

 the discoidal spot on the hindwings is ringed with blue. 



Limenitis sibilla. — July 12th. It was unfortunate that the weather 

 at the end of June and the beginning of July was unfavourable for 

 collecting. However, on July 12th, 13th, and 14th, when the sun, at 

 intervals, made efforts to assert itself, I tried for this species in aw 7 ood 

 near Angmering, where I found it not uncommon, but in ragged con- 

 dition, and rather hard to capture, as it frequented the bramble 

 blossoms which happened to be in the densest portion of the wood 

 where it was difficult to wield one's net. 



Dryas paphia. — July 12th. Plentiful in woods near Angmering. 

 I saw one very dark J , perhaps ab. valezina, pursued by four or five 

 $ s, but, unfortunately, when attempting to net her I only succeeded 

 in bagging one of the suitors.
