Hutuna, x. and xi., 20 ex. The Rennell examples of this species tend to have the transversemedian white line on the fore wing much finer, and have lost the white inthe cilia along the termen of the fore wing, where they are brown. Similar variationis also evident in examples which have been seen from Australia.Distribution: Bismarck Archipelago, New Guinea and Celebes.YPONOMEUTIDAE45. Anticrates dimua rennellensis subsp. n. (Figs. 19, 65-69)Anticrates difflua Meyrick, 1927, Insects of Samoa, 3, Lepidoptera, fase. 2, p. 106.The general coloration in the Rennell race is considerably brighter than that in thenominate race from Samoa. The markings of the fore wing are a uniform deep coralred in contrast to the light purplish markings, suffused crimson on the edges, indifJfua dijjfua. There is no apparent difference in the male genitalia of the two races.Male genitalia: Figs. 65. 66.Female genitalia: Figs. 67-69.Type c3': Rennell I., Tingoa, 9-11. xi. 1953, at light.

Labial pal pus slender, white. Head with face white, crown, thorax andtegula pale smoke gray. Antenna fuscous. Fore wing white, with a very pale goldensheen to middle, thence along costa and inner margin to 3;4 to merge with a narrowdirect transverse light fuscous fascia; a slender darker fuscous direct trans\erse linebeyond this at about 5/6; a conspicuous jet-black round apical spot surrounded bywhite from costa to torn us anteriorly and by fuscous from costa to tornus distally;cilia fuscous, white tipped around apex. Legs white, banded with fuscous-black.Male genitalia: Figs. 93, 96. The shape of the valva is an important distinguishingcharacter.Type c3': Rennell I., Hutuna, 18-25. x. 1953, at light.

The larva is known to mine blotches in leavesof Hassia lati/olia in India, and Mimusops elangi (Sapotaceae) in Java and Malaya.105
