In most parts of temperate North America the true Dragon-flies are among the most conspicous members of the insect class in any community where water is at hand. Strong of flight, quick as a thought in their darting movements, wary in the highest degree, they are usually well known to all by sight, yet not often captured by the amateur collector unless he takes the time to devote his special attention to them at some favourable place.

My last paper, npholding Dr. Hulst's determination that E.perlineata. Pack, is the above species, was intended also to convey the idea that until we knew positively that he was wrong it was better to accept his decision. Nor was it my desire to belittle the judgment of Mr. Prout, as I expressly stated.

Colletes clypeonitens, n. sp.—. Length 11 mm. Clypeus prominent, polished, narrowly medially sulcate, its puncutres coarse but scattered and not forming striæ, its apex slightly emarginate and preceded by a transverse rim. Malar space one and one-half times as long as broad, finally striate.

408. Autographa Sackeni, Grt.—Rare. A ♂ and two ♀ ♀ are labelled July 12th to 25th, taken in different years. At light, and flying in sunshine. The ♂ bears Dr. Ottolengui's label. As a matter of fact, this and the preceding species were returned to me bearing the wrong labels.

The following list of Orthoptera chiefly comprises the species taken by the writer during a month's trip to the Canadian Pacific Coast in 1897. But few stops were made, most of the specimens being taken at the various stations along the line of the Canandian Pacific Railway. As a rule, but a few minutes to half an hour were spent at each stopping place, but in Manitoba and British Columbia longer periods were spent, and better opportunities were to be had for collecting.

Stegomyia mediovittata, n. sp.— Probosics black, unmarked, palpi black scaled, in the male the bases of the joints white scaled, in the female only the apices of the joints are white; inner side of first antennal joint white scaled, scales of occiput black, a median line of white ones, those on the sides yellow and white.

Eutricha Oweni, n. sp., ♂.— Expanse, 70 mm. Thorax, abdomen and fore wings reddish-brown, more or less lightened from an admixture of pale gray or whitish scales or hairs. Fore wings crossed by four lines, one at inner fourth dark reddish-brown, accompanied by a pale inner line, almost transverse, only slightly incurved at costa and inner margin. The dark portion of the line is well marked, the paler portion not so distinct.
