though even Mr. Tutt was sceptical until I reared larvae from 
eggs laid in April, which were full-grown at the end of June. 
Unfortunately, taking these from home with me, they all died 
of starvation, as their food-plant was unobtainable. 
“ This year, however, I obtained eggs in the spidng from 
Ste. Maxime specimens, and have reared the specimens now 
exhibited. These emerged during August, and were dealt 
with by Mr. A. E. Tonge, who kindly took charge of the 
pupae when I went to Switzerland to find the larva of 
Latiorina {Lycaena) orbitulus. 
“ He endeavoured to obtain eggs from some specimens, hut 
owing to an accident was apparently unsuccessful, though 
in mid-September in looking over the plant on which specimens 
were caged, I noticed several leaves eaten precisely as is done 
by first-stage larvae of A. coridon. As the plant was indoors 
and not accessible to any other flies {P. icarns, or anything 
else), I have little doubt that eggs were laid, and one at least 
hatched, the others being destroyed by a predaceous enemy. 
“ In any case, making every allowance for the mild Eivieran 
winter, there can be no doubt that the larvae do some feeding 
in autumn and probably even duidng winter, in order to 
emerge in April. It certainly seems very improbable that 
they pupate in autumn and hibernate as pupae, but this is a 
possibility to be kept in view in further investigation—most 
likely the life circle is much the same as is that of A. thetis 
(bellaryus) with us. Whether this summer brood has been 
captured before or not, though one can hardly doubt that it 
has, we have no record of it, or of whether and how it differs 
from the spring form. 
“ The specimens exhibited afford at least a partial answer 
on this point. They are on the whole larger. The males have 
no trace of a discoidal spot: instead of only a few, nearly three- 
fourths of them are obviously of the ab. suavis, i. e. have 
orange spots on the upper surface, and this, although the 
margin of the hind-wing, is less darkly marked than in the 
spring brood. Beneath, the orange spots of the hind-wing are 
larger and of more bright and intense colour, and the line 
of chevron markings on the fore-wing is generally a nearly con¬ 
tinuous dark band, as it is only occasionally in the spring brood.
