A year ago last autumn, while rambling about the fields, we took especial notice of the galls upon the golden-rod. We saw that there were two kinds, the elongated and the round. We knew that from the former came a tiny moth, well-known to us, and from the latter a fly with which we were not familiar, or, if familiar, not known to come from this gall. The elongated galls were all empty, but the round ones we found upon examination contained each a small white grub. We gathered a quantity of the galls and placed them in a jelly glass on the writing table where they would be constantly before us for observation.

Orthezia artemisiœ, n. sp.—♀. Immature form, Antennæ and legs piceous. Body covered with white secretion. Dorsum with two rows of dentiform tufts; the first four directed forwards; the remaining seven, decreasing in size caudad, directed backwards. Nine lateral tufts; the first, on a level with the second dorsal tufts, at right angles to the body; the others directed backwards, and about of equal length, except the last two, which are longer and narrower, the last being longest. Caudal tufts extending caudad of last lateral tufts.

Cisthene striata, nov. sp.—Antennae and palpi black. Head, pro-thorax and patagia creamy, the prothorax of a deeper shade. Thorax above dull gray. Abdomen rose coloured above and laterally, gray ventrally, Legs brorwnish-gray.

Prof. cockerell's treatment of these genera is likely to create an erroneous impression, which should be corrected wherever his statements are made. In Trans. Am. Ent. Soc., XXIV., 150, he says : “It is perfectly evident that the so-called species of Panurgus of North America are not all of the same genus.” In the Dec. Can. Ent., p. 287, he says : “The result is extremely interesting, and seems to show that we have for many years been placing bees in genera to which they by no means belong.”

The Chalcidid subfamily Trichogrammatinae is composed entirely of species parasitic in the eggs of other insects. A synopsis of the genera has recently been published by Dr.Chr. Aurivillius in “Entomologisk Tidskrift,” for 1897, pp.249–256, apropos to the establishment of a new genus (Oophthora) for a species which he has reared in Sweden from the eggs of Semblidis lutariae. In this synopsis of the genera Dr. Aurivillius makes Lathromeris, Förster (Hymenopt. Stud., 1856, 2, pp. 87–89) a synonym of Chaetostricha, Haliday (An. and Mag. Nat. Hist. Ser. 2, Vol. 7, 1851, p.212).
