A Revision of the Moths of the Subfamily Geometrinae of America North of Mexico (Insecta, Lepidoptera), by Douglas C. Ferguson. Peabody Museum of Natural History, Yale University, Bulletin 29; hi + 251 pp. & 41 line drawings & 8 halftone plates. Yale U., New Haven, 1969; paper cover.
A classification based largely on male and female genitalia and on larval characters, of some 75 species distributed in 15 genera and 5 tribes. Of these, four tribal names, two genera, and 10 species are proposed as new. Some larval information is available on 32 species in 11 genera, and this information is used to support the tribal classification. Material from most of the major collections of North America except some of the western ones was employed. It is indeed a pity that our economic values force the moths of this group to be figured in black and white.—ed.
