it seems worth while to bring together the following 

 observations.* 



It is a singular coincidence that on passing through the 

 garden of the University of Bombay, 22 March, 1908, I 

 again saw a Catopsilia and watched it settle on a shrub : 

 this was not a yellow-leaved plant, as on the former occa- 

 sion, but its leaves varied a good deal in colour and the 

 butterfly settled on the yellowest: it was certainly much 

 less conspicuous than it would have been on the greenest 

 leaf: a German fellow-traveller whose attention I called 

 to the bvitterfly agreed as to the partial concealment by 

 the similarity in colour. 



Barbados, 18 December, 1906. A $ of Callidryas euhule, 

 Linn., was seen, when a cloud passed over the sun, to 

 flutter about some herbage for a short time, as though 

 looking for something, and finally to settle on a 

 yellow leaf of the "Life Plant," Bryoiihyllum calycinum, 

 Salisb. 



Constant Spring, Jamaica, 8 January, 1907. Two speci- 

 mens of G. eululc (sex not recorded) were seen when 

 the sky was dull to settle on the lower, yellowish 

 leaves of Plumbago scandens, Linn., close to the ground. 



Mackfield, Jamaica, 27 January, 1907. I was watching 

 the movements of a ^ C. euhule, when a cloud passed 

 over the sun ; after fluttering about for a very short 

 time it settled in the middle of a yellow, lower leaf of 

 the Bryophyllum. 



Montego Bay, Jamaica, 4 February, 1907. A $ (7. euhule 

 was seen flying across the race-course. The track 

 was carpeted with short grass of a rich full green, 

 but amongst the grass were long trailing stems of the 

 Ipomcea pes-capra}, Sw. ; on one of these stems was a 

 solitary bright yellow leaf, far from any other of like 

 colour, on this the yellow butterfly settled. 



Montego Bay, Jamaica, same day. A ^ C euhule was 

 seen to settle on an isolated yellow leaf of a creeper 

 in a hedge, about 6 feet from the ground, all the 

 surroundinir foliage being; crreen.
