They found in its mouth the buccal pieces of the Neuroptera, and, under the carapax, five pairs of branchial tufts attached to the segments that are invisible outwardly. Inside the animal were found tracheae, the digestic tube of an insect, and malpighian canals. Finally, in June, 1880, Mr. Vayssiere was enabled to establish the fact definitely that the insect belonged among the Ephemerids.
Nemertians, colours of. Neolithic period. Neomorpha, sexual difference of the beak in. Nephila, size of male. Nests, made by fishes; decoration of, by Humming-birds. Neumeister, on a change of colour in pigeons after several moultings. Neuration, difference of, in the two sexes of some butterflies and hymenoptera. Neuroptera. Neurothemis, dimorphism in.
Then without expressing his views as to the position and affinities of the Lepismidæ, he remarks "as the upshot of all this, then, while the Collembola are clearly more nearly allied to the Insecta than to the Crustacea or Arachnida, we cannot, I think, regard them as Orthoptera or Neuroptera, or even as true insects.
If, among a group of insects such as the Neuroptera, we find different families with all grades of perfection in metamorphosis, it is possible that larger and higher groups may exist in which these modes of metamorphosis may be fixed and characteristic of each.
That is to say, the Coleoptera, Orthoptera, Neuroptera, Lepidoptera, etc., are in my opinion, more nearly allied to one another than they are to the Poduridæ or Smynthuridæ. On the other hand, we certainly cannot regard the Collembola as a group equivalent in value to the Insecta.
