But in the Lymantriidae the antennae are pectinate and the ocelli are absent; while in the Noctuidae the antennae are usually sim- ple and the ocelli are usually present; and when the antennae are pectinate the ocelli, in all cases known to us, are pres- ent : in this way a distinction is preserved between the two families. Although it is hard to find a distinction between the two that can be put into words, the general appearance of the Tussock-moths is very different from that of the Noctuids, and entomologists have no difficulty in deciding to which family any species belongs. The Tussock-moths are chiefly nocturnal; but the males of Notolophus fly in the daytime. The larvae of our native species are very characteristic in appearance. The body is hairy; there are several con-.
