on account of their beauty and high value, while those of the 
second brood were neglected. It is, at least, what takes place at 
Bordeaux with respect to Anthocharis cardamines, which is 
double-brooded, on the hills which border the Garonne, at two 
leagues distance from the city. Collectors in Bordeaux despise 
the first brood which appears in March and April, because it is 
smaller and less beautiful, and go in search of the specimens of 
the second brood, which are remarkable here for their large size 
and brilliant colouring. Let us suppose A. cardamines to be a 
species in great demand, as collectors say, that is to say, a 
species for exchange, the Bordeaux ‘amateurs’ would not fail to 
despatch specimens in large quantities, as they have done with 
the unfortunate A. Belia, which is ruthlessly hunted every year. 
The Bordeaux type of A. cardamines would not fail to pass as. 
larger and more brilliantly coloured than the specimens of the 
north, and nomenclators of varieties would not fail to christen it 
—perhaps ‘cardaminoides.’ Finally, the foreign ‘amateur,’ 
passing through our city, who might think it a great treat to 
take ‘propria manu’ this beautiful variety, would be cruelly 
disappointed, when going to catch it at the ordinary time the 
insect makes its appearance, i. e., in April, only to obtain 
specimens exactly similar to those of his own country. ‘The 
date given by Duponchel for the emergence of P. dispar, 
according to information sent from England to M. Alex. Lefebvre, 
is extremely vague ; possibly this vague information was given 
on purpose by English collectors anxious to keep their monopoly. 
June, July, August, he says. Does that indicate a single 
generation? Here we take it in June and in August; but, as I 
already stated, the individuals taken in August are totally 
different to those taken in June.’ —A.rrep Wartiy; 110, Clapham

(P. dispar was, I believe, not double-brooded in this country. 
The larva was to be found feeding upon the water-dock, Rwmex 
hydrolapathum, in May and June. ‘The imago made its appear- 
ance in July and August; there was never any attempt to make 
a monopoly of the insect, nor to make any mystery as to its time 
of appearance by the collectors. It was very abundant; and 
when | first knew the fens, over forty years ago, the imagos were 
to be purchased from the collectors at from 3s. to 4s. per dozen. 
I have seen but few specimens of the continental Hippothoé, so
