A year ago, May 1902, I had a peculiar entomological experience. I had returned from Florida to my home in New York about the middle of April, had spent two or three weeks arranging and classifying my captures of the winter, sending off duplicates and doubtful species to specialists, and preparing my collection for the summer months of my absence. A full fortnight must pass before I should leave town for my New Hampshire summer home, and I already pined for a little collecting. Suddenly I recalled the existence of some old boxes of insects which had been crowded out of my regular collection-room some years before. They were in a closet opening from a hall on the second floor. This closet had been built especially for the preservation of woollen clothin and its protection from ravages of the devouring moth, its walls, shelves and drawers being made of red cedar.

On the 24th of May I went collecting, with a friend, in High Park. We each took a specimen of the Tailed Blue (L. comyntas), but found, as we had expected, that it was too early for Scudder's Blue. On turning over an old boot that was lying on the grass, I saw a chrysalis of L. Scudderii attached to the under side; an ant was also on the sole of the boot, and ran round and round and over the chrysalis several times before going away; being, apparently, quite agiatated by the disturbance. Is it possible that this ant was keeping some sort of guard over the chrysalis, as ants are supposed to do over the larvæ of L. Scudderii? Its presence on the boot may have been merely accidental, but still, its movements gave one the impression that it was loth to leave the chrysalis, and would have liked to carry it away, if that had been possible.

Crioceris12-punctata, Linn, is an introduced species, and has been working northward from Maryland, according to Professor J.B. Smith, who some time ago informed me that it was present in New Jersey, and would in time reach Connecticut. The first speciment recorded from the State was taken by a student assistant June, 16th, 1902, who collected a single speciment on asparagus upon the Station grounds in New Haven. On May 23rd, 1903, I took male and female specimens from the same locality. We may now expect this species to become thoroughly established here as a pest of asparagus, beetle, C. asparagi, Linn.

The genus Corethra was founded by Meigen in 1803,* on Tipula culiciformis, De Geer, and in April, 1844, Leow erected the genus Mochlonyx† on Corethra velutina, Ruthe, basing it on the shortened first joint of the tarsi, a character mentioned by Ruthe in his original description. The characters of the tarsi of culiciformis cannot be ascertained from De Geer's description and figures.‡ On page 386 of the same volume of his Memories, which contains the account of this species, is a description and brief account of a related species, which he named Tipula crystallina, with a reference to Reaumur's Memories, V., plate 6, figures 4–15, where at 4 and 7, a more slender larva without a trace of a subanal respiratory tube in shown, contrasting with the broader larva furnished with a large respiratory tube, as represented in De Geer's figures of culiciformis,; the descriptions and figures which these authors give crystallina do not indicate the characters of the tarsal joints of the adult.

The following list of Coccidæ, which have been sent to me for study, adds considerably to the known range of a large number of species, while several new food-plants are indicated; and as no records of the species herein cited have appeared, to my knowledge, other than in one or two instances in some of my published papers on the Coccidæ, it seems, therefore, that these miscellaneous results should be recorded. It will also show to some extent what is being done in a private laboratory for the advancement of science.

The Sawfly here described is a common pest on the leaves of various speices of Populus in Montana, and a Bulletin dealing with its life-histroy and economic significance is about to be published from the Montana Experiment Station. We give here an outline of its life-history, followed by descriptions of the two sexes.

The adults appear on the foliage in May and continue there for about eight weeks. The female deposits her eggs singly on the very young, tender leaves, and at the same time stings, them in such a way as to cause the edge to fold under on the lower surface.

1899. Myrmosidæ, Family, Ashmead; Journ. N.Y. Ent. Soc., VII., p. 49 and 52.

1903. Mullidæ, Famille (partim), André; Wytsman's Gen. Ins. Fam. Mutillidæ.

This family, as here defined, is, I think, a natural one, although some of the genera have been placed previously, by different authors, in other families, with the Scoliidœ, Myzinidœ, Mutillidœ, etc.

The females in this family may always be easily recognized by the thorax, which is distinctly divided into itwo parts, while the males, except in three or four cases, are easily distinguished by the genitalia, the hypopygium terminating in a sharp aculeus, which curves upwards, as in males in the family Myzinidæ with which they are often confused.

Some time ago, while in St. Louis, I called on Dr. Geo. W. Bock, and saw in his collection a remarkable specimen of a female Lucanuselaphus, from Popiar Bluff, Mo. On my expressing interest in the matter, the Doctor very kindly gave me the insect, and I wish to put the case on record.

It is well known that a small percentage of the people in this country, and perhaps in all countries, are more or less colour-blind, and it is a noteworthy fact that such persons are often entirely unconscious of it or do not fully appreciate its disadvantages. The officials of the railroads and certain other corporations test the applicants for situations, and if they are found to be colour-blind, or not able to distinguish colours accurately, they are not employed. It will be readily seen that if a railroad engineer or the officer of the deck on one or our large passenger ships could not distinguish between red and green signal lights in the night, most disastrous accidents might be the result.

Records of duplication of members in hexapod larvæ are so rare that I submit the subjoined account, drawn up from a specimen of the young of Corydalis cornuta, captured in the river near Iowa City, several years ago. The insect is one of a number that I took for class dissection, and as far as noted, the remainder did not depart from the ordinary type. A notice of the case was prepared at the time and sent to a scientific journal on the eve of its suspending publication, so that I think the article was never printed.

Desvoidy published this species in 1827, in the Memoirs of the Society of Natural History of Paris, Vol. III., p. 408. The entire description is as follows:

27. Culex Consobrinus, R.D.

Simillimus præcedenti; palpis, tarasique bruneis.

As I was sitting in Victoria Park, London, Ont., on one of the early days of August, 1902, a sharp click on my straw hat indicated to me that a beetle had been suddenly arrested in its erratic flight. I took off my hat and found thereon a longhorn, with the familiar outline and ornamentation of the Clytus group. But there was something about it that seemed unusual to me, and the more I looked at it the more I was convinced of its novelty. So I secured it, killed and mounted it, and, as opportunity presented itself, endeavoured to determine it, but could find nothing with which it would correspond, and the books afforded me no relief. Having occasion to require the assistance of Mr. W. H. Harrington, Ottawa, upon some B.C. beetles, I sent my unique in order to secure his verdict upon it.
