In 1976 we published "Ant Larvae: Review and Synthesis," which we regarded as a summary of our life-time of research. During the following years so many new larvae were added to our collection and so much was published about ant larvae that we decided another general treatment was desirable; so in 1986 we published a "Ten-Year Supplement" to include additions and revisions to our Memoir. In 1987 and 1988 additional material warranted a supplement to the "l0-year Supplement" in 1989a. This article is the third supplement to the Memoir.
In the supplement, two genera are characterized, one generic characterization is revised, and references in the literature are increased by 43. Changes in our Memoir (1976) and its supplements (1986, 1989a) are noted.
