This subfamily comes nearest to the Aporinæ, and a few of the males are easily confused with and mistaken for some males in the latter group.

The head is, however, lenticular, very thin antero-posteriorly, the temples being very flat, while the antennæ are always placed much closer to the mouth, on or below an imaginary line drawn from the base of the eyes. These characters ought to enable the student to recognize readily a wasp falling in this group.

Some males in the subfamlry Aporinæ have a lenticurar head, but in these the antennæ are inserted above this inraginary line, never on orbelow it.

An interesting contribution by Dr. FJetclrer, entitled “Entomological Record, 1901,” has just appeared in the 32nd Annual Report of the Entomological Society of Ontario. This, besides giving a list of the active workers in Canada, includes careful notes on rarities, etc., taken during the year. It is the intention of the Society to continue this Record from yeart to year, and as this will undoubtedly prove useful to entomologists throughout Canada, it is hoped that collectors in the dominion will try to make it as complete as possible. Records of interesting specimens captured, either from the standpoint of distribution or rarity, will be acceptable, and should be sent to Dr. James Fletcher, Central Experimental Farm, Ottawa. Specimens unknown to collectors will gladly be identified.

Pamphila barbara, sp. nov.

Habitat: Bolivia. Expanse: 1 12 inches.

Head, thorax and abdomen abovd, dark brown; below, gray. Antennæ dark brown, with white annulations at base of each joint. Club brown, white near base.

General colour of upper surface blackish brown. Hind Marginal fringe of ground colour.

Upper side of fore wing has an indistinct white dot in apical area. Near centre of wing, under the end of discoidal space, are two prominent white dots, the upper being under median, the other being in next lower interspace, larger than the first and somewhat nearer base.

On June 1st, 1901, while on a mosquito hunt with Mr. J. Turner Brakeley, at Lahaway, we investigated the little pools around the head of a swamp spring. The water was very cold, and our object was, mainly, to ascertain wheter Aedes larvæ occured in such localities, where pitcher plants were in the vicinity.

In the course of our dipping I found a very odd little wriggler, altogether different from anything I had ever seen befor, and soon Mr. Brakeley found the same thing. We took only a few of them at that time, and from their minute size I assumed they must be very yound. I afterward sent a specimen to Dr. Howard, and he appeared as much at sea concerning its location as I was. It seemed to be a Culicid larva, without much doubt; but that was as far as we could get. The specimens were about an eight of an inch in length, light reddish in colour, and very hairy in appearance. The head was very broad, and from it the body taped gradually to the short obtuse anal siphon.

The following specimens were collected at San Diego. California,during the year 1901 by Mr. G. W. Dunn, and are now in the collection of the Academy of Natural Sciences of Philadelphia. The terms used in the descriptions are those adopted by Comstock and Kellogg in their recent work, “Elements of Insect Anatomy”.

Some lime ago, when about to publish a synopsis of the genus Scolops, the writer discovered that Dr. Uhler had the same genus in hand and his MSS. read for the press. As the result of the correspordence,the writer dropped his work for the time, and Dr. Uhler promised to send his types as soon as his paper was published. (Proc. Md. Acad. Sc., p. 401, 1900.) With his usual thoughtfulness, the Doctor sent on the types,and with the aid of these and a fine series of eastern forms received from Mr. Otto Heidemann the author has been able to definitely place all the described species and recognize a number of nerv ones.

The genus is found in its greatest abundance the border line of plain and mountain region, and so many rew forms have been found here in the past few years that there are no doubt many more to be found on further search.

Eulecanium fraxini, n. sp.–Adult ♀ scale 6 mm. long, 5 broad,2 high; some individuals are practically circular in outline and variable in size. In July the scales are well covered with a grayish powdery secretion; this being removed they are reddish brown, considerably wrinkled and pitted, surface shiny, texture thick.

Boiled in potash the derm becomes very clear and transparent, showing some large gland-pits 24 μ in diameter. Mouth-parts, legs and anal plates tinged with yellow.
