The beetles of this family are more characteristic of Southern latitudes than of cold climes like Canada; of about six hundred species known from America, north of Mexico, only ninety-six are recorded from the Provinces whch form the subject of the present paper. From all other families they may at once be known by the antennæ, terminating in a club composed of lamellæ or plates, which are capable of close opposition or of separation at the will of the insect.

I can find no record of the breeding of Hymenopterous parasites from water beetles, in either the European or American faunas, and it is, therefore, with considerable pleasure that I here describe two distinct species of Hymenopterous insects, reared from water beetles by Mr. H. F. Wickham, of Iowa City, Iowa, belonging in genera not yet reported as occurring in our fauna.

The following descriptions are offered, preparatory to publishing a list of the saw-flies of the Upper Cayuga Lake Fauna. The types are in the Entomological Collection of Cornell University.

Thanks to the identifications of Prof. Smith with the British Museum collection which contains Walker's types, we have now a certainty as to the correct names of almost all our species. It is clear from different remarks in the catalogue that under Mr. Butler's rearrangement of the material some shifting of the specimens described by Walker has taken place, and this shifting has equally certainly led here or there to an accidential shifting of label.

Since 1861, the date of Hagen's Synopsis, only three additional species of Chryospidæ have been recorded from the United States— one from Florida, one from Texas and one from California. During the past summer I received a short note from Mr. A. P. Morse, of Wellesley, Mass., enclosing a few specimens of Chrysopidæ which he thought might prove new to our collection.

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.

Food plant.—Clarkia elegans, etc.

Egg.—Shaped like a white table squash without the scollops; usually laid on the flower buds, the young larva feeding inside on the parts of the flower; hatched in eight to eleven days.

My types of albalis, now in collection Brit. Mus., belong to a western species showing a charactertistic white downy surface of the primaries, obscuring the ornamentation. My single type of cloanthodies in coll. Graef, belongs to a smooth-winged from with distinct, sordid or brownishblack Cloantha-like markings. It does not appear that albalis has an European representative, while cloanthoides is not unlike Agrotis signifera, of which latter it may be the American representative.

Anisosticta strigata, Thumb. Very abundant, found under stones, bark and other objects in nearly all pasture and meadow lands. I have never taken it while feeding. A colony of over fifty was taken from under one stone the past summer.

As a supplement to my list of additions to Canadian Coleoptera published in Can. Ent., Vol, XXI., I beg to submit the following list of species taken since 1889, in Canada, and, as far as I can learn, not recorded in any of the published lists.

In the identification of species I have been aided by Mr. Ulke and Dr. Hamilton.

On August 10th, I left by the 4.45 p.m. ferry fro the Isle d'Orleans, whch was reached about 5.30. A short walk uphill brought me to one of my favourite collecting grounds, and the remaining daylight was usefully spent looking for Coleoptera, a few good things being taken.

In the Canadian Entomologist for May (page 140) there appears an article by Mr. Wm. H. Patton, entitled “Zethus Aztecus in Florida,” in which the author attempts to prove that Zethus Poeyi, Slossan♂ and aztecus are the same species. As I am the authority for one of these species, it was but natural that I should make a study of the trio, in order to ascertain if Mr. Patton's assertions were correct.

In a previous paper there were given analytical tables to the genera of the families Aphorouridæ and Poduridæ; in the present paper will be found a table to the families and a table to the genera of the Entomobryidæ. The Smynthuridæ and Papiridæ are each represented by a single genus.

Aside from the wasps distinguished by their folded wings (Diploptera) and the Chalcidian genus Leucospis, there is no record, unless of distant date, of any Hymenopterous insect having the wings folded. In Coptera the “longitudinal fold” described by Say is in reality a pleat of ridge; the wings, as I have repeatedly observed in the living insect, being laid flat upon the back and never folded.

In a lot of flies sent me from Illinois, by Professor S. A. Forbes, I find a most remarkable species, which I am satisfied must be located in the Syrphidæ, though the wing shows no sign of the spurious vein, and the first posterior cell is open. The third antennal joint bears a terminal arista, which character is shared by only two previously known North American genera; but the remarkable charater of the fly lies in its hind tarsi.

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.
