This paper contains descriptions of some apparently new species of inchneumons from British Columbia. Most of these are contained in a very interesting collection made by the Rev. G. W. Taylor, during his residence at Cedar Hill, near Victoria. V.I. When Mr. Taylor left Ottawa to return to Victoria, about three years ago, he very generously handed over to me his Hymenoptera, only asking that I should publish a list of the species. To enable me to fulfil this request, I have found it necessary to first prepare descriptions of the new species.

An oversight (ante p. 167, line 27) leads me to state that it is in the Aporid section of the Pierinœ that the pupa has the adbominal segments 5 and 6 moveable, whilst in the Pierids proper only 5 is moveable. The Pieridi have until now alwasy included the Apord section; as a matter of fact, many Europen systematists have placed our Aporia crataegi in the genus Pieris.

My type is in the British Museum, where it has been examined by M. Ragonot, who compares it in his description with the European D. abietrella, from which this authority finds it to differ structurally. The figure in M. Ragonot's magnificent work seems to me excellent. I take this occasion to express my dissent from the classifaction adopted in the Philadelphia List.

♂—Head produced and very flat, rounded in front, wings reaching tip of abdomen; colour gray-brorvn. Length, 9 mm. Length of head, 2.3 mm.

Head thin foliaceous, margins very thiu, a median, thicker space, which beneath widens to base of head, forming a convex keel. Eyes touching prothorax.

In the two preceding papers of this series 36 species and 3 varieties of Acridiæ have been recorded as occurring in Indiana. Since the last paper, published in the Entomologist for February, 1892, appeared, five additional species have been taken within the State, and many lacts have been gathered concerning the life history, habits and range of the species previously recorded. Moreover, my private collection has been largely increased by exchange for specimens from other parts of the United States, and I have possessed myself of almost all the literature extant upon the group, so that I am enabled to clear up a few mistakes in synonymy rvhich crept into my first papers.

A fleshy leaf-tissue gall was found on terminal twigs of Populus Monilifera(?) June 18, 1892, a few miles to the north of Ojo Caliente, in Southern Socorro county, New Mexico. This gall is somewhat similar in method of formation to one that has been found on Rhus microphylla, which possesses a cock's-comb-like appearnce.

Last December Mr. H. J. Elwes gave a revision of the genus Chionobas in Trans. Ent. Soc., London, to which Mr. W. H. Edwards, in the March number of the Can. Ent., gives “notes” or rather exceptions, in which he still contends that Gigas, Californica and Iduna are three distinct species, but now allows Nevadensis, which he formerly considered also to be distinct, to be a synonym of one of these, but does not know of which Elwes has placed these four or one species, just as they are in the “Synonymical Catalogue” issued by me in 1878, nor can I understand how anyone can imagine there is more than one species under the four names; there is absolutely no point by which any of the examples can be separated, whether they come from California, Washington, Oregon or elsewhere; were they to be mixed indiscriminately, without locality labels, no one could say from whence came this or that exmaple, or which was this or that so-called species.

Some remarks made by Mr. Grote in his “Note on Acronycta cristifera” lead me to support his contention that in the British Museum “types may have become misplaced.” I am, of course simply a specialist at European NoctuÆ, and only such material from outside countries as helps my work (more especially with the British species) has any great interest for me, and only so far as this can any remarks that I make be considered of value.

The members of this group are distinguished, as already stated, by the position of the abdominal spiracles, which are placed in part on the superior poriton of the ventral segements, the rows feebly diverging; the last spiracle usually visible behind the elytra.

Galls of this species were sent me by Mr. Trevor Kincaid, of Olympia, Washington, who writes that they were collcted from the twigs of Quercus garryana. The galls are ellipsoids, from 5 to 7 mm. in greatest diameter; they are smooth, monothalamous and snuff coloured, both externally and internally, and are attached by a small projection to the side of small twigs.
