This genus contains the common large black field crickets and the house cricket, which has been introduced into this country from the Old World. But three species have been taken in Ontario. All of these are dimorphic as regards wing-length, the shor-winged from being the normal one in the field crickets, the long-winged form in the house cricket.

The Geometrid moth described below cannot be placed in any European or American genus known to me, and I therefore venture to institute a new genus for its reception.

The genus belongs to the Ennominœ, and the absence of a tongue and the possession of the dordal abdominal tufts serve to separate it readily from all the other Americal genera of the subfamily, as none of them, I believe, posses these two characters in combination.

43. Sphœophoria micrura, Osten Sacken.— Two females from Port Renfrew, one July 6, 1901, the other Aug. 16, 1902. The male was taken at Seattle, Wash. July 15, 1901.

44. Sphœrophoria sulphuripes (Thompson).— One male specimetn, taken at Glacier, July 20, 1901, belongs here questionably. It lacks the characteristic bunch of yellow pile on the hypopygium of cylindrica, but otherwise resembles that species quite closely.

Macrosiphum ambrosiœ (Thomas).— Siphonophora ambrosiœ, Thomas, Bull. Ill. State Lab. Nat. Hist., 1878, p.4.

Found at Pecos, New Mexico, on Lactuca. The following account is based on the Pecos specimens:

Very dark brown, very shiny; legs, antennæ and nectaries black, except that the basal part of legs, to near middle of femora, is brownishwhite; stigma pale green; cauda of winged ♀ yellowish-white.

Fore wings chrome yellow, a pink patch at base of wing, about 3 mm. wide; this is most marked on costa and between median and submedian veins. A subterminal pinkish band, broad at base, where it is confluent with the pink fringe; at centre is narrow and furthest removed from margin, at inner angle it broadens out, becoming again confluent with fringe. Fringe pink, in one speciment slightly paler inwardly. Hind wings pale yellowish white, firnge concolorous.

Since Mr. A. W. Hanham published his lists of Manitoba Lepidoptera in the Canadian Entomologist (1897–1901), many additional species have been taken in the Province by myself and other. Where no special locality is given in the following list, the capture was made by me on my farm on the Long River, and in almost every instance the identification has been made by Dr. John B. Smith, to whom my warmest thanks are due for the kindly that he has taken with my material.

This paper belongs with the series on local species—Andreninæ, Megachilidæ and Bombinæ, Tr. Am. Ent. Soc., 28: 187;29: 163; Sphecodinæ, Ent. News, 14: 103; Balictinæ, Nomadinæ, Epeolinæ, Anthophila, Can. Ent., 34: 245; 35: 172, 284; 36: 37.
