Aleurodes mori, n. sp.

Egg.—Length, .16 mm.; width, 08 mm.; elliptical, curved, light brownish in colour, marked with minute polygonal areas; pedicel short, about one-tenth length of egg.

Larva.—Length, .43 mm.; width, .3 mm., varying somewhat; shape, elliptical; colour, whitish or yellowish white. Margin all around dentate, due to the usually short but acute incisions between the closely-set wax tubes. A very fragmentary marginal fringe frequently present; no submarginal rim as in pupacase.

In the many accounts of this insect, I do not recall that attention has been called to the odour that is associated with insect, and which, in cases of excessive abundance, can be detected at a considerable distance away. Where the air is quiet it is often possible to detect the presence of a badly infested tree a yard away, and I presume that with more acute olfactories, such as insects are supposed by many to possess, even the presence of a more limited number of the scale might be detected at a much greater distance.

Ripersia arizonensis, n. sp.

♀ enclosed in a broadly oval snow-white waxy sac, about .3 mm. long, 2 mm. wide, 1½ mm. high, sac widest between middle and caudal end.

♀ oval, about one-third longer than broad, shiny, light purplish-brown, about .3 mm. long. When boiled in K. H. O. turns reddish-brown. Derm colourless, with numerous bristles scattered over the dorsum. Antennæ 6-jointed: 6 longest, joint 4 shortest; formula 6, 1, 2, 3, 5, 4. Each joint with several hairs, joint 6 quite bristly.

Psilopa petrolei, new species.

black, polished, not light coloured, pruinose except the lower part of the occiput, cheeks and sides of face, which are thinly grayish pruinese; halteres yellowish, the knobs white. Eyes densely hairy, most approximate at middle of face. Third joint of antennæ slightly longer than the second, the spine of the latter not reaching beyond the apex of the antennæ. Wings hyaline, tinged with gray on nearly the costal half, except sometimes a spot toward apex of the submarginal cell; apex of second vein nearly twice as far from the first as from the apex of the third vein. Length, 2 mm.

I am not aware that the full life-history of this insect has been published, though I shall not be surprised to learn that such is the case.

In order to know how long a time should intervene between the first and second dippings for the cure of scab, we must know the period of incubation and also the entire time elapsing from the deposition of the egg up to the time that the mite from that egg, if a female, may be itself depositing eggs.

♀ scale nearly circular, somewhat flattened, little convex, roughish, dark gray above bark, reddish-brown below bark, 2 mm. diameter; exuviæ little exposed, often concealed by whitish secretion, orange, placed to one side of centre; ventral scale, delicate and white; old scales dark brown, often almost black. Scales are thickly massed.

♀ oval, white, marked with irregular light yellow spots; first and second lobes, and margin of last segment, yellowish.

Melitea Maria, n. sp.—Male: Expands 1½ inches. Upper side. Primaries. The outer margin of the wing has along its edge about eight brick-red spots; internal to these is another row of yellow spots, separated from the former by a very small space. Next comes a row of yellow spots, the first four having an outward curve, and the lower three an inward curve. There then comes a row of quadrate brick-red spots, nearly parallel to the preceding yellow row. At the end of the cell are three yellow quadrate spots. The cell has in it two comparatively large red spots, outlined with black, and having a yellow patch between them and another toward the base. There is also a quadrate yellow spot with concave sides in the space below the third median nerve. The secondaries are marked in a similar manner.

In the annual reports of the Canadian Experimental Farms for 1896 and 1897, Dr. James Fletcher describes a new apple-fruit pest in British Columbia, caused by the attacks of small caterpillars, viz., the larvæ of a little tineid moth, Argyresthia conjugella, Zell. The injuries done by this new enemy, called by Mr. Fletcher “the applefruit miner,” closely resemble those caused by the apple maggot, Trypeta pomonella, Walsh. The caterpillars tunnel the pulp of the fruit in every direction, leaving brown-coloured channels with rather large chambers here and there; this attack thus being easily distinguishable from that of the common codling worm.

Otiorhynchus ovatus is an insect which, during the last decade, has become decidedly more numerous in Canada than was formerly the case. Little seems to be known about its habits. It has been sent to me occasionally with complaints of its attacks upon various crops. Among these may be mentioned injuries to the growing stems of potatoes, and also injuries to fruit in the fruiterer's shop. The beetles have been also sent in frequently as having been found in considerable numbers huddled together in dwelling houses late in autumn. Perhaps the most interesting complaint which has been made comes from Prof. W. L. Goodwin, of Queen's University, Kingston, who writes: “I send two specimens of a small beetle which caused so much annoyance in camps on Wolf Island, in the St. Lawrence, near Kingston, Ontario, in July last. It attacked us at night and bit with unpleasant severity.”

Some years ago, Dr. Erwin F. Smith called attention to the fostering of this aphis by a species of ant, Lasius claviger, and, although not able to actualiy witness the act, his studies of the actions of this ant about the roots of peach trees infested by this aphis led him to believe that the former brought the latter from below ground in spring and placed them upon the twigs, thus indirectly if not directly causing their diffusion in orchards.
