The following list of moths is the result of collections most during the months of June and July, 1904, in the neighbourhood of Temagami Lake, which is situated in the Nipissing District of Ontario, north of Lake Huron, Lat. 48°.

Of the water-bugs, perhaps Ranatra and Nepa are better known than the others in their anatomy and earlier stages. Dufour's classic on the anatomy of Nepa cinerea, L., and Ranatra linearis, L., has been followed by the work of other investigators in these two species, and the peculiar filamentous ova of the two genera have long been favourites with students. But neverthless, thus far no compelte life-history has been worked out for either of them.

Prof. Smith of New Jersey, records TŒniorhynchus (Culex) squamiger, Coq., as being a strictly fresh-water form in the State, and it will be interesting to know that so far as my experience goes during the past season, it is exclusively a salt-marsh mosquito in the San Francisco Bay region of Californa.

An insect which, fortunately, has only been reported on a few occasions as doing damage in Canada, is the Bean Weevil, Bruchus obtectus, Say. Authetic instances of injury by this insect haven been received from one locality in Ontario, and from two in Quebec. The injury in all cases was to seed beans.

In Chap. X of the Descent of Man, Darwin says that when the male of Gryllus campestris is chirping, “first one wing is rubbed over the other, and then the movement is reverse.” I have carefully observed several hundred males of our native Gryllus, and it seems to me that one tegmen (“wing”) is always uppermost. This is, at first sight, a very minor point, but it leads to some rather interesting thoughts.

Dolerus Cookei, n. sp.—Female.—Length, 4 to 4.5 mm. Expanse of wings from tip to tipm 8 to 9 mm. General colour effect of body dark brown to black. Head back of, about and beneath ocelli, sparsely clothed with whitish hairs. Clyepus sinuate, incurved, yellow, sparsely pilose. Labrum polished yellow. Antennæ dark brown to black, stout, pilose. Joint i annd ii subequal, short; rest subequal, longer. Antennal foveæ circular, deep.

In a recent number of this journal* Mr. Quayle gives some notes on the habits of the Californian Culex squamiger, Coq., and compares these briefly with those of a species occuring in Nw Jersey which we have been calling squamiger (following a determination by Mr. Coquillett), and suggests the possibility of there being two forms. The identification of our species with the Californian one has been doubted by Prof. Smith and myself since we learned of the salt-water habit of the latter; but not until Mr. Quayle pointed out the difference in the length of tracheal gills of the larva was a close comparison of the species made.

From the Island of Mindanao, P.I., comes a very pretty mosquito.

Toxorhynchites argenteotarsis, n. sp.—♀. Head densely covered with very dark brown flat scales, with bronze-blue iridescence, a light blue-white band around the eyes, and a few brown bristles; antennæ dark brown, the basal joint densely covered with flat white scales; palpi with very dary brown, almost black, scales, bronze-blue iridescence, the penulimate and antipenultimate joints with narrow violet apical bands; proboscis very dark, practically black, with bright bronze-blue irirdescence; eyes black, clypeus black.

Among the fossil insects collected at Florissant, Colo, by Judge J. Henderson and Dr.F. Ramaley, of the University of Colorado, is a species of Corixidæ, represented by numerous individuals. It occurred, as Judge Henderson informs me, in the first railroad cutting east of Florissant, a little above the middle of the seciton there exposed. The shale containing the speciments is very much lighter than that in which the other Florissant fossil insects seen by me are imbedded, and it is believed to belong near the top of the series.

Throught the kindness of Mr. F. H. Wolley Dod, I have now in my cabinet specimens of 13 species of “Pugs” taken by him in the neighbourhood of Calgary.

Three of these belong to well known and widely-distributed species, viz: Eupithecia cretaceata, Pack.; E. ravocastaliata, Pack.; and Eucymatoge anticaria, Walker.

Since the final impression of my “List of the genera of the Pagiopodous Hemiptera Heteroptera,” etc. (a), I have received from my friend, Dr.O.M. Reuter, a very valuable summary of his most recent thoughts on the Classificatio of the Miridæ (b).

The 109th meeting of the Toronto Branch was held in the Provinical Museum on March 20th.

The event of the evening was a paper by Dr. Brodie, entitle “Insect Intelligence,” in which attention was drawn to some classes of insects which seemingly exhibit an unusal amount of brain develpment in the will-power shown in the deliberate selection of ways and means. This was followed by a discussion, in which Dr. Abbott gave some interesting examples from personal observation of the skillful way in which insects adapt themselves to abnormal conditions.

The “confusion worse confounded” in which the mosquitoes of America are at present enveloped may be illustrated by the two following instances:

In the August number, Canadian Entomologist (1904) I described a mosquito from Benecia, Cal, as Grabhamia de Neidmannii, and, some time afterward, received a note from Mr. Coquillett, stating he believed it to be his Culex squamiger (orginally published as Tœniorhynchus).
