The preparatory stagees of this pretty Phalenid are not given in Packard's “Monograph of the Geometrid Moths”, nor cited by Henry Edwards in his “Catalogue of the Preparatoy Stages of N. A. Lepidoptera”; and, since they differ in some regards from the general characters of the caterpillars of the genus as given by Guenée, I have drawn up a brief account of larva and pupa.

Eight years ago, in Indiana, I found a gall on this grass that had somewhat the appearance of a diminutive ear of corn with the husks, but more pointed and minus the silk. The husks (I can find no better term for them) were imbricated and pointed, being placed regularly, one over the other, leaving the junctures along the margins. In this gall I found a pupa or, as seems now more probable, a puparium, but reared no insect therefrom.

My first practical acquaintance with this species began at New Brunswick, N.J., in the spring of 1889. In the Rutgers College campus there are a considerable number of elms, many of them grand old trees, which for several seasons ins succession and up to 1888 had been defolidated by Galeruca xanthomelœna, larva and imago. A double row of young trees, many of them elms, extends from the College campus to the Theological Seminary, a distance of about 280 yards, and at the beginning of this row, most distant from the Seminary, the Experiment Station building in situated. There are also a considerable number of elms among the other shade trees in this part of the city.

In the forest-clad portions of the Pacific Coast Range, from the Columbia River northwards inot British Columbia, there are frequently seen on the trunks of pine trees which have been injured and blackened by fire, small white fungi almost globular, or slightly flattened and kidney shaped, varying much in size, but frequently attaining the dimensions of a pigeon's egg. This fungus, kindly determined for Mr. E. A. Schwarz and myself by Prof. Galloway, is Cryptoporus (Ployporus) volvatus, Peck., var. obvolutus, Peck.

How often, in turning over the pages of his check-list, has the American collector of beetles allowed his eyes to rest a moment upon those lines of type which announce the existence in our fauna of the mysterious family Stylopidæ, with its two genera, Stylops and Xenos; each represented by a single species; but, recognizing in these names only the records of captures almost legendary in their antiquity, he has turned the page with a feeling that they represent to him unattainalble rarities.

I desire to call attention to the species of this genus, in order to get further information, if possible, as to the occurrence of the species in this country. The species of the genus that were described by Jenyns (Annals of Natural History, 1839, III., p. 241–244) have often been considered simply as the common house-bug occurring upon the different animals which they were described as infesting—the bat, the pigeon, and the swallow.

Male: From of Th.quadrinotata, Fab., but with the vertex shorter and more depressed. Greenish-yellow; head yellow with a transverse black band on the anterior edge; body black the segments edged with yellow. Length 4½ mm.

Head rounded before, very little longer at the middle than next the eye. Vertex a little depressed, anterior edge subacute; apex of the front two-thirds the width of the base, sides nearly parallel below the antennæ. Clypeus strongly widened apically where the width is but slightly less than the length, edge of the cheek rectilinear either side of the prominent lateral angle. Pronotum rather long, hind edge but moderately concave, the angles obvious.
