no black present. The subterminal line of the females of both species is better defined than in the males. The subterminal line in a boreale female is often almost as well defined as in a falacer male.
Boreale is usually collected on or around ash (Fraxinus), and Acer negundo L.

A NEW SPECIES OF CAMERARIA ON BUR OAK IN MANITOBA
(GRACILLARIDAE)
T. N. Freeman Entomology Research Institute, Canada Department of Agriculture, Ottawa
During the past few years some officers of the Forest Insect Survey of Canada, Department of Fisheries and Forestry, have been studying the biology of an undescribed species of Cameraria Chapman which is reported to be abundant on bur oak, Quercus macrocarpa Michx. in the vicinity of Winnipeg. The description of it is presented here to assist those officers in the publication of the results of their investigations.
Cameraria macrocarpae Freeman, new species
General. Antenna white, banded with dark fuscous dorsaliy. Face white. Tuft white with a few ochreous scales. Thorax golden dorsaliy and with a few white scales. Forewing shining golden ochreous with three, equally spaced, outwardly angulated, white, transverse fasciae; first at basal one-quarter, second near middle, and both margined outwardly below angle with black scales; the third at outer four-fifths margined with black scales throughout its length; a short, white, subapical, costal streak followed by an area of scattered black scales in middle of wing; fringe pale grey with a black basal line in tornal region. Hind wing light grey; fringe whitish. Abdomen pale ochreous. Legs whitish with small black patches outwardly. Wing-spread: 8.0-8.5 mm.
Male genitalia (Fig. 1). Uncus sub-triangular. Clasper clavate. Aedeagus clavate. Ventral flap sub-conical.
Type material. Holotype male, Bird's Hill, Manitoba, 10 April 1968 (reared in laboratory). No. 11033 in the Canadian National Collection. Paratypes: one male, Bird's Hill, 13 March 1968; four males, one female, Bird's Hill, 22 April 1969; one male, Bird's Hill, 27 April 1969 (all reared in laboratory).

Mine. A large upperside blotch containing several larvae. Flight period. Late July to late August.
Remarks. This species is allied to the Myrica feeding Cameraria pic-turatella (Braun) n. comb. It may be separated by the presence of three, transverse fasciae on the forewing as opposed to one fascia on that of picturatella.
