DEIOPEIA PULCHELLA IN ENGLAND. 155 
On a former occasion I stated that D. pulchella was probably 
not permanently established in this country, and I may add that 
I still entertain this view. There is little doubt that—like Colias 
edusa, D. livornica, Plusia gamma, and certain other species which 
it is unnecessary to mention—D. pulchella is a migrant. The 
proper European home of the species is south of the Alps, and 
especially along the shores of the Mediterranean ;* it is common 
in Asia and Africa, and its range of distribution extends to 
Australia. In America it is replaced by D. bella. 
With regard to the specimens of D. pulchella taken in England 
this year, it seems exceedingly probable that they are immigrants ; 
not, however, simply specimens that have been blown over from 
the French coast, for, as a matter of fact, the species is as uncer- 
tain in its appearance in other parts of Central Europe as it is in 
England. Should specimens of the species occur here in the 
autumn (if the summer is favourable they probably will do so in 
some numbers), they may, I think, very properly be considered 
as the descendants of a new stock. It would, therefore, be of 
considerable interest if, from the present time, everyone having 
the good fortune to capture a specimen or specimens would make 
a point of placing such capture on record. Of course D. pulchella, 
even as an immigrant, has a perfect right to a place in our 
collections. I am not aware of the larva of the species having 
been found in England, although I have no doubt that it has 
often been searched for, especially in places where the moth has 
occurred. Imagines were said to have been bred about 1856 from 
ova deposited by a female captured at Torquay, but no particulars 
are given (Entom. v. 243). Mr. Tugwell (Hntom. xi. 186, 251) 
gives us a most interesting account of the metamorphoses of the 
species. From eggs received from Mentone in May, 1878, moths 
were bred in July; from these one hundred eggs resulted, but 
only about a third of that number produced larve, some of which 
pupated in August, and yielded moths in September. A female 
of this second brood, having duly paired, deposited a few eggs 
each night for a fortnight, but all were infertile. Mr. Tugwell 
supplied the young larve with a garden variety of Myosotis and 
also Borage officinalis, and he observed that the former was 
preferred. Afterwards the common forget-me-not, Myosotis 
palustris, was introduced, and seemed to be greatly enjoyed by 
the larve, as they ate both flowers and leaves. 
Myosotis is the pabulum given by most of the authors that I 
have consulted, but some of them mention Heliotropium europeum 
and Solanum tomentosum (not British plants); Kirby adds Plan- 
tago; and viper’s bugloss (Hchiwm vulgare) has been mentioned 
as a food-plant. 
** Mr, J. J. Walker says the species is always common at Gibraltar, but 
** was so numerous in the middle of May, 1887, as to be a nuisance” (HK. M. M, 
xxiv. 182). QX
