For the new combination of name as given above, I am indebted to R. L. Usinger,who worked it out from literature at the California Academy of Sciences. The species leucostictos was described from Java, and according to Fruhstorferhas severalvariations, and ranges from farther India, to the Nicobars, Sunda Islands, and Formosa. Kadu was described from Guam, and according to Matsumura has been taken in Formosa and the Ryukyu Islands. F. X. Williamsrearedaspecimen from Ficus retusa at Los Banos, Philippines, June 28, 1921.

We found this fine blue butterfly fairly common on forest trails in Guam. It was reared ononly one occasion. A black caterpillar was found on leaves of a broad-leaved Ficus at the Asan reservoir, August 22 . It formed a chrysalis ina TODO few clays, and the adult issued September 3. Our material wasidentified by comparison with a specimen labelled "Salpinx kadtt Esch." at Philippine Bureauof Science, Manila. The description of lwdtt by Eschscholtz is apparently from the male, although it is not so stated. Our Guam material was of both sexes. The color and spotting is about the same in both sexes, but Esch-, TODO scholtz's description of the widely curved. backward extension of the inner margin of the forewing so that it covers a considerable portion of the costal part of the hinclwing applies only to the male. There is no such expansion of the inner margin of the forewing in the female, it being nearly straight. Also, the female hindwing does not have the large costal pale area of the male where covered by the expansion of the forewing.
