The describer of species has accomplished his task when he has given the proper Latin names, but it depends largely on the one who catalogues the species, whether these names pass into use or not. In the work of preparing a “New Check List of North American Moths,” I have gone over much of the literature bearing on the subject, and the following reflections have presented themselves to me.

In the first place, I have been actuated by a sincere desire to meet the views of the anti-Hübnerists, and avoid the use of old or objectionable names. Professor Riley has brought forward objections to the resuscitation of forgotten or neglected names, and others have written with the same object in view. I found, however, to my surprise, I must confess, that the best Catalogue, that of Staudinger, did not hesitate to introduce names out of use for almost a century; and this merely because they were a very little older than the name in common use. So prominent an insect as Papilio Podalirius, is made to appear as P. Sinon.

Egg.—Diameter, .03 inch. Globular in shape, slightly flattened at the base, the apex having a punctured space but no depression; a series of longitudinal ridges from near the base, 20 of which reach the apical space. As these ridges are the same distance apart, there are between those reaching the apex several shorter ones, the number not noted. The depressions between the ridges show slight punctures. Color pale green. Duration of this period 5 days.

Young Larva.—Length .15 inch, slender, 12 legs, the first and second pair of pro-legs mere points. A looper in motion. Color of the middle of the body from joint 2 to 11 pale dull yellow, with a slight leaden hue; head, joint 1 and the anal joint slightly reddish, these parts lacking the leaden hue. All the feet pale. Hairs arising from piliferous spots gray. Head about one third broader than the body. Duration of this period 3 days.

The reader will have noticed, in the June number of the Canadian Entomologist, a paper on the “Physiological Arrangement of Insects.” The author there places the Orthoptera first in this list, owing to the presence of auditory organs and well developed eyes. The “arrangement” which follows is exceedingly “mixed,” but the object of the present remarks is to point out that the author mistakes when he considers the presence of sense-organs as the crucial test of rank. And for this reason, that, within the different Sub-orders, there is great variation in this respect. For instance, in the Pyralidœ we have forms almost identical, such as Chryseudenton and Cataclysta, which differ by the absence or presence of simple eyes. I do not wish to follow out the argument at length; the environment seems to effect comparatively easily the sense organs; Cave-insects are frequently blind.
