A FURTHER FIELD NOTE ON ISOPARCE CUPRESSI (SPHINGIDAE) A description of the larva of Isoparce cupressi (Bdv.) was given by the author (1973, J. Lepid. Soc. 27: 1-8), accompanied in the same issue by a field note by Van Buskirk (p. 83-84). Both articles omitted mention of a larval character brought to notice in the caterpillars collected by Van Buskirk near McClellanville, South Carolina. In my description of the development of the larva, much at tention was given to the brown on the dorsal stripe and on the spiracular areas. In Van Buskirk's specimens, many of them showed no such brown except for the dorsal horn and on the second thoracic spiracle. Instead, the areas mentioned showed the same yellowish white of the lateral lunules. All degrees between the two extremes were seen in the wild larvae. Van Buskirk's wild caterpillars included various instars collected over a very few days, and so represented the offspring of several different females, leading to the conclusion that the natural coloration of the larva is variable in this respect.
