fond of settling when meaning to remain settled 

 for some time. In bright sunshine they often settle 

 on flowers with wings partly or entirely spread, but 

 in dull windy weather like this morning's, they are 

 apt not to fly unless disturbed, and then to settle 

 again very soon. I disturbed one G. rapm, $, eight 

 times and watched it settle again seven times. 

 Five times it settled on hramhle, although there 

 was plenty of other vegetation. Of the other two 

 times, the first was on the head of a yarrow, and 

 the second on another low plant close to a spray 

 of hramhle with recurved leaves, which it closely 

 resembled at a little distance. 

 Aug. 27. Saw G. hrassie/B, $ , settle twice on hramhle 



and close up its wings. 

 1898. Sept. 7. Have several times lately, when 

 coming up Sandy Lane at dusk, seen G. ortj^c'B 

 settled, apparently for the night. Generally on 

 hramhle, wings quite closed. They will allow 

 themselves to be seized with fingers or forceps, 

 but then generally wake, and fly off if let go. 

 Aug. 8. Observed that L. iearus is fairly well pro- 

 tected (i.e. concealed) on heads of bramble-blossom 

 when wings are closed. 

 1898. Aug. 9. Mortehoe. Saw H. tifhonns, $, settled 

 on a bramble-leaf in sunshine, eye-spot showing. 

 Cloud came over the sun, and titlionns shut up, 

 eye-spot becoming invisible. Opened again when 

 cloud passed. 

 This observation was referred to by Professor Poulton. 

 [Trans. Ent. Soc. Lond., 1902, p. 372.] Compare the 

 observation on Tcracolus ione, p. 104, 105, siiiJra. 



1904. Highcliff, Hants. Aug. 8. Watched G. hrassica}, 

 $ , settle down for the night about 7.15 p.m. After 

 much fluttering about the stems of tall grasses, it 

 came to rest on a head of hawkweed in the ^^o^jj^^s 

 condition, and remained there with wings hanging 

 downwards and closed over its back. 

 Recently M. J. Th. Oudemans has published an in-

 Eepos chez les Lepidopteres." *
