out that part above it being also affected. Besides if a dew drop could thus 

 concentrate the rays of the sun like a burning glass, the chrysalis would be 

 first affected, and the insect so injured as not to be likely to emerge." Mr. 

 Eobson has seen no other species marked in the same way, except one speci- 

 men of Erebia Blandina, in his own collection, which has the left wing so 

 affected ; but Mr. Mosley has figured a specimen of Thecla rubi, from Mr. 

 Gregson's collection, which may decidedly be called bleached. In the British 

 Museum is a singular specimen of this variety of Janira, which is remarkable 

 for the confluence of the discoidal patches on the forewings. The most 

 beautiful I have of these bleached examples is a male, which I captured at 

 Glanvilles Wootton, on June 28th, 1864. The specimen is apparently fresh 

 from the chrysalis, and what is left of the dark colour is of a very rich dark 

 brown indeed, being mostly at the base and round the margins. All the 

 wings are coloured in a similar manner, and on both the upper and under- 

 sides ; the eyed spot being almost hidden. Four other males I have of this 

 kind. One has the right wing white, other wings of the normal type. A 

 second has the two right-hand wings almost white. A third has a white 

 patch near the hind margin of both left-hand wings. A fourth has a slight 

 white patch on the two forewings. Females of this variety are more scarce, 

 but I have one which I took at Glanvilles Wootton, on July 2nd, 1872, with 

 the right-hand forewing entirely white, and the eyed spot scarcely showing. 

 Mr. Tugwell has a very remarkable example with the right forewing quite 

 white, with the exception of the eyed spot, and a few yellowish streaks near 

 the centre. The hindwings on the same side have a yellowish-white band, 

 corresponding with the pale band of the underside. The wings on the 

 opposite side are very different, the forewing being marked more like the 

 ordinary female, but yellow instead of fulvous, while the hindwing resembles 

 that on the right side, except that the band is yellow instead of white. A 

 female I took at the Land's End, in August, 1864 (the great year for bleached 

 varieties), has the fulvous patch on the forewings replaced with yellowish- white. 

 Another very extraordinary form is what may be called the drab variety. 

 It has all the wings of a very pale brownish drab, with the eyed spot scarcely 

 showing. The finest specimen of this variety I captured at Glanvilles Woot- 

 ton, on June 20th, 1864 ; being singularly enough the first of the species I 

 saw in that season. Another very extraordinary form has all the wings of a 

 very pale ochraceous, except a fulvous patch, in which the eyed spot is 

 situated. It was taken by my father in the Isle of Arran, on July 29th, 

 1825. A female I took in the Isle of Harris, on July 29th, 1883, has a dis- 

 tinct fulvous band on the hindwings. The undersides of the males from that 

 locality are unusually dark. Perhaps these belong to the variety named in
