510 SEASONS OF INSECTS. 
But perhaps you may prefer considering the whole 
summer appearance of insects as divided into three prin- 
cipal seasons. This may thus be done. ‘Their vernal 
season may commence Llorente Caprea, and end Florente 
Oxyacantha ; their summer, Florente Oxyacantha and Flo- 
rentibus Umbellatis; their autumn, Florentibus Umbellatis 
and Forente Carduo. In the jirst, the number of insects 
will be daily zxcreaszng ; in the second (which is the har- 
vest of the Entomologist, when his eyes and his hands 
ought to be every where), they will reach their utmost 
complement ; and in the third, they will be gradually de- 
creasing in number, till they generally die, or go into 
winter-quarters. At this time many minute Diptera and 
Ichneumons take shelter from the weather in the windows 
of our apartments. ‘These seasons will not always exactly 
correspond with our usual reckoning, and take place at 
the same time; since, being regulated by our varying tem- 
perature, they will be sometimes sooner and sometimes 
later, sometimes longer and sometimes shorter. Though 
I have not named a brumal season, because insects are 
in winter usually torpid,—yet some, as Tinea Novembris, 
Geometra brumaria, and many Tipulide, even then make 
their appearance. 
If you ask, Whether it be not possible to regulate our 
Entomological seasons by the appearance of insects them- 
selves? I should answer, that probably this might be 
done; but that further observations seem wanted to en- 
able us to do it satisfactorily. Perhaps the appearance 
of Formica rufa beginning the business of the year might 
form the commencement of one season; the flight of the 
orange-tip butterfly (Colias Cardamines*), of asecond; a
