Pompilus, Fabr., is preoccupied, and the family name Pompilidæ must be changed to Ceropalidæ, as has been shown recently by Fox (vide Ent. News, Vol. XII., 1901, p. 268). In consequence, my subfamily Pompilinæ must be changed to Aporinæ.

This subfamily is unquestionably the largest in number of genera and species of any of the groups of the family Ceropalidæ (Pompilidæ). Most of the species, in comparison with those found in the Pespinæ, are of medium size or small, few attaining much over an inch in length, while the vast majority are much smaller.

The Coccidæ herein descirbed were collected by Professor L. Bruner in 1867 and 1898. I examined the collection with more than ordinary interest, as practically nothing was known of the Coccidæ of the Argentine or Paraguay. The flora of the southern part of South America resembles in many respects that of the arid region of North America, and it was therefore not wholly unexpected that this resemblance should extend to the Coccidæ. The collection is too small to show how far such a resemblance may extend, but the species of Orthezia and Lichtensia, at least, are entirely representative of North American types.

Among Hymenoptera which I sent to Provancher in 1855 was a sawfly which he determined as Nematus malacus, Nort. As it did not correspond to the description of that species, it was set aside with some undetermined material. While rearranging my Nematidæ, I recently examined the insect to ascertain its position, and found that it had simple claws. As it has not the appearance of Gymnonychus, I was somewhat puzzled until, on examining the wings, I found the lanceolate cell was widely contracted as in the subfamily Cladinæ, instead of petiolate as in the Nematinæ. The insect, therefore, must be placed in the genus Anoplonyx, which Marlatt has separated from Camponsicus, which has bifid claws. As no representatives of these genera were known to Marlatt when he published his Revision of the Nematinæ (Technical Series No.3; Dept. Agric, U.S., 1896), the following description of this Canadian form is submitted:

While studying the specializations of the wing in the Papilionides, the general results of which are published in the Proc. Am. Philosophical Society, Jan., 1899, I found that Iphiclides, Ajax, Marcellus, etc., differed so strongly from the type of Turnus as to be generically separable. Ajax is, in fact, allied to species having a greenish or yellowish white ground colour, from South America and the Old World, while Turnus is evidently related to the black North American forms, Troilus, etc., with which it flies. This fact enables me to draw the probable conclusion that Glaucus represents the original colour of the species, which, so to speak, is turning into Turnus, The black ♀ Glaucus is the more conservative whereas the males are already, with very rare exceptions, of the yellow tape of Turnus. It is different with certain cases of so-called “melanism,” now spreading in Europe, as Eubyja var. Doubledayaria and Aglia vars. fere-nigra and melaina. Here the original ground colour is changing to black indifferently in both sexes.

At the time of writing the paper on the red-winged Catocalæ* I thought I should very soon complete the list; but other matters have too long crowded out the work I had planned to do. I shall now give, however, my idea of how they should be arranged, with some notes on some of the species.

The genus Eremopedes was established by Scudder in 1894, CAN. ENT., XXVI., p. 178,181. It was founded on a femal specimen in the National Museum, but the species was not described till 1900. Previous to that date Mr. Cockerell described a species from New Mexico, together with a colour variety of the same, and I can now add a third species to the genus. In connection with its description it may be well to give a short account of the genus, which may be characterized as follows:

Insects of medium size. Head with the fastigium moderately prominent. Thorax with the prosternum unarmed.* Pronotum smooth, moderately rounded, nearly as much arched posteriorly as anteriorly, and without carinæ. Legs moderately spinose, hind pair long, the femora extending far beyond the tip of the abdomen, usually as much as half their length. Fore tibiæ spinded above on the outer margin only, the spines three in number. Ovipositor moderately curved upwards.

Anyone who has had even the slightest experience in attempting to get intelligent notes to accompany his acquistions by exchange has doubtless been sorely vexed–to put it no more strongly. Anyone who has tried to keep a careful record of the conditions under which his own collections were made has also doubtless felt the need of some better scheme than the regulation notebook. It is for these reasons that I suggest an idea whic I find very useful.

In the first place, I write (or print with a hand stamp) my own locality labels so that I can fix the places definitely. The ordinary entomologist, unless he has a large collection from precisely the same limited locality, can scarcely afford to have special labels printed, and general ones are useless when the collection is to be used for more than a purely æsthetic exhibition.

In the Catalogue of the Lep. Phalænæ, p. 528, this species is incorrectly referred to C. venosa. The specimens there recorded are probably all C. venosa, at least those from my collections are. Mr. Geo. Francke sends me two fresh specimens of C. Cressonana. In these, as stated in my original description, Proc. Ent. Soc., Phil., June, 1863, the third stripe of C. venosa is wanting. The stripes on cubitus and branches and along anal region of primaries may vary from white (as I described them) to yellow, and the costa may be yellow (in the first instance)or red. For the yellow-striped from with red costa I propose the name var. Iutea. The fringes in C. Cressonana are entirely white, and I was careful to point out other differences from C. venosa, which should not have been overlooked by the author of the Catalouge above referred to.

In reference to recent “protest” in the pages of the CAN. ENT. (Vol. XXXIII., p. 263) against a change in the generic name Eupethecia, I believe its abandonment, in favour of a Hübnerian name chosen cut of the Verzeichniss by Mr. Meyrick, to be invalid. I retain it myself in the collection here for the reason that its date is certain, and there is a rule of the German zoological code that if exact dates cannot be ascertained (and this is the case for that part of the Verzeichniss which contains the Geometrids), preference shall be given to the genus which has a type cited. This is reasonable, and custom has correctly sanctioned the use of Eupethecia. I an indebted to Mr. L.B. Prout, of London, England, for the information that Curtis himself, in founding the genus Eupethecia, explicitly chooses absinthiata, L., as type of the genus, April 1, 1825. In my study of the Geometrid genera (1895–96), only a fragment of which appeared in the Transcations of the Entomological society of London, I pointed out some of the errors into which I have reason to believe Mr. Meyrick has fallen.
