Volume 4 is undoubtedly one of the most needed volumes in the series, there being no other English language work available covering this group of moths, and it has already been acclaimed as one of the finest. Part 1 contains the special chapter, followed by the Systematic accounts of the Oecophoridae and eight smaller families - a total of 147 species. Part 2 comprises the Gelechiidae - 162 species. There are genitalia drawings for both sexes of each species, and also representative figures of wing venation for each family, as well as other diagnostic characters. Appropriately, this volume also contains a tribute to the late A. Maitland Emmet, who sadly died while it was in preparation. Among the 19 contributors to this volume are four leading Continental lepidopterists. The families, all within the Gelechioidea, are treated as follows: (Part 1) Oecophoridae - M.
