This excellent manual was written with the avowed intention of bringing the pertinent information concerning chiggers between the covers of a single volume. In this the authors have succeeded admirably, although information on the Trombiculidae is accumulating rapidly as indicated by a publication noted in the appendix which adds over 70 new species to the 440 species included in the manual. The main section of the manual deals with classification of 4 recognized subfamilies, 31 genera and 17 subgenera, with keys and brief diagnoses. The species are listed with synonyms, distribution and host lists. The classification is based wholly upon larvae. A brief chapter is devoted to the impact of chiggers upon public health. This is considered under three headings: relationship to rickettsia, dermatitis and control.

A review of the literature interspersed with original observations is presented in brief chapters on the behavior of chiggers, life cycles, and anatomy, particularly of the larvae.
