PROTECTIVE RESEMBLANCE. 245 



can learn J, faiista is monophagous, while var. jucunda would seem to 

 be a less dainty feeder; I have actually watched a female deposit an 

 Qgg on tTenm moutantiui ! This on the Glarnisch. 



Leaving this fascinating moth I should add that those who take 

 Burnets will find much to interest them in the valley. PKrjniralis, 

 scabiosae, acliilleae, exulanA, trifolii, lonicerae, flilipendulae, traiisal/>ina, 

 astragali, pencedani, and ochsenhi'iiiieri are all represented here on diffe- 

 rent parts of the slopes. One of the best moths I have found there is 

 Flnsia aeiiiula, which seems to be almost plentiful; this moth is very 

 rarely taken in Switzerland. 



As I do not intend to make out a long list of all that is to be taken 

 in my Eldorado, I cannot do better than terminate this short article by 

 advising you to put in at least one night at the Klubhiitte, where you 

 will sleep, and sleep grandly, on a bed of hay covered by an Alpine 

 Club blanket ; your bed will cost you lOd., and the view from your 

 bed-room window alone should be well worth £10 to any lover of 

 nature. A long stay at the Klubhiitte presents certain inconveniences 

 to one who cannot get along without his morning tub, but even this 

 difficulty may be got over if you are not overburthened with shyness. 



[Mrs. Page has promised to continue these notes for me, speaking 

 of Glarnisch as she found it in this, the very worst year in the memory 

 of the long-lived Glarus peasants. — -P.A.H.M.] 



Protective Resemblance. 



By C. W. COLTHRUP. 



(Continued from page 1S2.) 



With regard to Mr. Curtis's remark that "in this country our 

 butterflies are up later and to bed earlier than our birds," this would 

 leave about six hours in which the birds could feed on them while fly- 

 ing, yet, as far as I know, we have no case of " mimicry " among 

 butterflies in this country. On the other hand, if we consider the Rev. 

 K. St. Aubyn Rogers' observation, cited by Mr. Curtis, " that tropical 

 buttertties rest at a time when t.ro]ncal birds are most active in pursuit of 

 food,'' "mimicry" would appear not to be necessary at all. 



On page 97 Mr. Curtis says, " My own experience confirms the 

 recorded observations of many other observers, the moriui/ insect is 

 attacked wliere the still one often escapes." Here again he confirms what 

 I have said, as it is quite obvious that the weeding out process, neces- 

 sary to bring about "protective resemblance," cannot take place with 

 moving insects. It is inovement that is fatal. The roebuck and other 

 so-called cryptically coloured animals in the wild state know this and 

 stand or lie perfectly still. It must not be forgotten, however, that 

 their enemies would see them before or at the same time. Another 

 point is that their enemies rely mainly on scent, and more often than 

 not are on the warpath at night, as anyone who has spent nights out 

 in the woods, etc., as I have, can testify by the heartrending squeals 

 one hears. I note, however, that Mr. Curtis was not deceived by the 

 " freezing " roebuck, which " looked like a weather beaten oak stump," 

 and I imagine its natural enemies would not have been either. I should 

 regard the above as an instance in which, to use Mr. Curtis's own 

 words, " rariei/ation of colours tends to inconspicuonsness quite apart from 

 udiether the colour and surroundings match or not." An exceptionally
