Head of moderate size, not retracted; eyes round, hardly prominent, yet distinct and of good size; front protuberant inferiorly, with a roughened depression guarded by a sharp rim; palpi small, slender, not attaining the end of the protuberance; tongue weak, yet of moderate length and perhaps, functional; antenna in the male with the joints a little marked, ciliate rather than bristle tufted. Thorax oval, convex, collar and patagia distinct but not uplifted; vestiture scaly; no tufs; legs moderate, on normal proporations, without spines, spurs or other armature save the usual spurs of tibiæ.

This paper continues the enumeration of the species of Halictus found in Maine, begun in the Canadian Entomologist for February, 1905, page 40.

Halictus similis, Smith, ♀ ♂.— A very common species in this locality, taken from June 19th to August 24th. It visits a great variety of flowers, as the blackberry, Iris versicolor, Sagittaria latifolia, Aralia hispida, Cornus Canadensis, and teh thistles and goldenrods. Professor Cockerell, who has examined Smith's type in the British Museum, states that the Maine specimens agree with it in all the more important characters.

Nomada Granicheri, n. sp.—♀. Length, about 10½ mm.; black, with bright lemon-yellow markings, the only red is on base fo antennæ, legs, and a little on mandibles; mandibles simple; anterior coxæ without spines; basal nervure meeting transverso-medial; third antennal joint slightly longer than fourth. This is a Xanthidium with the face black in the middle and with yellow lateral marks, like teh European N. succincta.

267. Euxoa nesilens, Smith(Jour. N.Y. Ent. Soc. XI., 192, Dec., 1903). —Described from Calgary and from Brandon, Man. The type is a Calgary specimen in Prof. Smith's collection, and a ♀ co-type is in my own. The description says: “In general appearance it resembles siles, but does not have the black basal streak, nor the blackish suffusion between the ordinary spots. On the other hand, it does have more complete, better marked median lines … Its distinctness is clear, and its association is with basalis, from which, however, it differs obviously in colour.”

Acting on the information given me by a woodchopper who had seen hundreds of green flies under the bark of a tree he had felled a few days previously, I made a further investigation, and upon reaching the locality found several dead Lace wing flies crushed under the bark of a Tamarack tree he had been sawing up. Furthur search undert the bark of a tall dead Tamarack (Larix occidentalis) which had just been felled, resulted in a rather unique cathch on removing the bark, which peeled off easily from the butt end, hundreds of lively specimens of the minute Tineid, Lyonetia speculella, Clem., were found.

The spring here was an unusually cold and late one, and it was not until April 17th that I saw a moth of any description, and that “first swallow” was only a Depressaria Canadensis, Busck. I did not see a single specimen of Leucobrephos Middendorfi, Men., though an April seldom goes by without my doing so, and generally at some awkward moment when no net is handy. Year before last I was repotting some plants on the sunny side of my house, when a Leucobrephos flew against me, dropped at my feet, and was off again before I could pot it.

Between 2 and 3 o'clock on the afternoon of Oct. 11, 1904, I observed remarkable flight of “Water Boatmen” at St. Paul, Minn. Thousands of them were flying hither and thither over several asphaltpaved streets, which had just been watered, and on which the sun was shining; the temperature was about 60°F in th shade, the sky was clear, and there was no wind. The insects evidently mistook the wet asphalt for water. Thousands of them alighted, and were held fast by the flim of mud until they died. About 5 o'clock I noticed on one street a struggling “Boatman” to every square inch of surface.

Colletes Vierecki, n. sp.—♀. Length, 11–12 mm. Shining black, form stout, body almost bare. Clypeus slightly convex, not sulcate, closely striato-punctate, sparsely clothed with short, pale pubescence. Supraclypeal area convex, shining and impuncatate medially, and with crowded punctures on the margins. Face crowded with good sized punctures, and with very short, erect, pale pubescence. Antennæ black, the flagellum more or less dull brownish beneath, the scape deeply punctured, joint 3 a shade shorter than 4, decidedly shorter than 5 and the following, which are shorter than wide.

Fore wings white, with small orange patch at apex, marked with black dots and bars as follows: Six spots on costa, about equidistant, the basal one slightly removed from costa and the second smaller than the others, a round spot in cell, followed by four short parallel transverse bars beyond it, lying close together, the third one joining spot on costa. A short longitudinal dash on inner margin at base, followed by five transverse bars from median vein to inner margin, the first, however, not quite reaching it. Of these the third and fifth are narrower than the others and in the male especially tend to become broken, probably in some specimens they would be almost or quite wanting.

Since my “Notes on Hydrometra Martini, Kirk.,” in the Canadian Entomologist for January of this year, pages 12 to 15, I have had the opportunity of examining another specimen fo Say's var. australis,” and study of it confirms the conclusions I then drew. It is unquestionably a good species and not merely a variety, and it affords me real pleasure to recognize true Hydrometra of which Say is the author.

(339. Leucania anteroclara).—Specific characters in this genus are often by no means strongly marked, and though they may be on the whole fairly constant, are as Prof. Smith expresses it in the “Revision” hard to locate in words. Anteroclara seems to be, at any rate, a pretty well marked form, but when its range of variation in this locality is known, specimens are to be found closely approximating no less than six different species, or, at any rate, forms standing under six different specific names viz.: commoides, multilinea (Calgary form), phragmitidicola, Calgariana, farcta and roseola.

♀.— Length about 15 mm; similar in size, build and pubescence to E. floridana (Sm), except that the hair of thorax above is entirely bright orange-fulvous; hair to occiput and vertex (except some black hairs at sides, but including the conspicuous interocellar tuft) is pale orange-fulvous; and the wings are not so dark.
