The number of species on the wing is now considerably lower, yet there is a good deal to be done both with butterflies and moths.

Many of the former are worn and ragged, but good fresh specimens of some species may be taken. Clover and lucerne fields and the flowery borders of corn fields remain very attractive.

Tree trunks and palings should be searched as before. Sugar still attracts numbers of the Noctuæ; and ivy blossom should be examined at night whenever an opportunity offers itself.

September is a good month for larva hunting. Most of the species that pupate in the autumn are now full fed, and will undergo the change to the chrysalis state shortly after they have been housed, thus giving but little trouble to the entomologist. The day feeders may be beaten or swept from their food plants, but,

of course, the nocturnal species are best discovered by searching at night.

Some have already 'gone down' for the winter, and, consequently, pupa hunting may be started. However, as there is yet much to be done with imagines and larvæ, it may, perhaps, be better to leave the pupæ alone till about the end of the month, especially as many of the larvæ have not yet had time to complete their transformation.

The list of imagines for September includes:

OCTOBER

As there is very little winged life this month, and the larvæ have nearly all sought out their winter quarters, special attention may be given to pupæ. The earlier this work is started after the insects have completed their change the better. If left late, many pupæ will have been destroyed by floods, moles, &c., and a prolonged series of frosty days may render digging unproductive if not impossible. Again, it must be remembered that some larvæ are not yet down, and by digging at the roots of the trees on which they are feeding, you are preparing an acceptable bed for the late species, for the pupæ of which you may call again in about a month.
