hiding-places earlier, and set about the business of egg-laying at a 
time quite impossible in Britain. 
The study of a collection of Lepidoptera made by Dr. Chapman 
during the last week of February, throughout March, and the first 
fortnight of April, at Cannes, Grasse, and the neighbourhood has 
perhaps helped to emphasise these points. From this collection one 
would surmise that whereas in February very few diurnal Lepi- 
doptera are moving, and that this month thus resembles April with 
us, the rapidity with which emergences follow each other in March 
suggests that three weeks at Cannes at this time is sufficient to com- 
prise the whole gamut of development which occurs with us in May 
and early June, the middle to the end of April seeing at Cannes the 
termination of what may be called the purely spring species, the 
advent of the summer ones, and the rapid growth towards maturity 
of the larvee of second broods of the early spring species—Spz/o- 
thyrus alcee, Thanaos tages, Syrichthus malve, Chrysophanus phleas, 
Cyanirts argiolus, Everes argiades, Polyommatus icarus, P. baton, 
Nomiades melanops, V. cyllarus, Papilio machaon, P. podalirius, Pieris 
daplidice, P. brassicae, P. rapa, P. napi, Anthocharis belia, Colias 
edusa, C. hyale, Melitea cinxia, Argynnis lathonia, Pararge egeria, 
and P. megera. ‘These feeding larve are the progeny of the eggs 
laid in March and early April, and they will produce a second brood 
during the summer months, some as early as May and early June. 
These in turn will, in due course, produce in some species a third 
brood in July and August, the progeny from which will go over the 
winter. 
As a supplement to these remarks, which are based on a series of 
letters from Dr. Chapman and the examination of the specimens 
captured, I append a complete list of the diurnal Lepidoptera 
seen or captured by him during the spring of this year, chiefly at 
Cannes.
