Santa Rosa Peak, May 19, reared from green caterpillar on Morinda indica , Usinger ; Dededo, Sept. 7, reared from Morinda indica , Swezey ; Piti, Oct. 20, at light, Swezey ; Yigo, Nov. 8, reared from green caterpillar on Morinda indica , Swezey .

This variety is known from the Moluccas and Tenimber [Timorlaut] Islands east to Tahiti, Austral Islands, Marquesas, and the Tuamotus. It was collected in Guam by Fullaway in 1911. Specimens in Tring Museum were recorded previous to that. We caught it at light, and also reared it. Caterpillars were found on other occasions besides those listed, but failed to mature.

There are two specimens in Bishop Museum, labeled " Chroniis erotus craniptoni Clark " (male and female cotypes), named evidently for Dr. H. E. Crampton who visited Guam in 1920, the date on the specimens. I have not been able to find in literature where Clark described this variety, but I presume that it is the same insect which Rothschild and Jordan have recorded from Guam as Chroniis eroftts eras. I cannot see what differences warrant the new varietal name.
