15. MACROHETEROCERA OF RENNELL ISLAND BY D. S. FLETCHER, f.r . e.s. DEPARTMENT OF ENTOMOLOGY, BRITISH MUSEUM (NAT. HIST.) The material on which this paper is based is solely that collected by Mr. and Mrs. J. D. Bradley for the British Museum during a six weeks visit to Rennell Island in October and November and a two days visit to Bellona Island in November 1953. The collection from the two islands consists of 388 specimens representing 87 species, 18 of which were found to be new to science and all but three of these, which are placed only to genera because of insufficient or imperfect material, are Qescribed in the following pages together with ten new races of known species. The collection made by the Danish expedition to Rennell Island in 1951 is very disappointing, due to poor weather conditions and an unfortunate accident to the collecting equipment; of the families included in this paper, there are only four moths, in too poor condition for identification, and a number of larvae, which, without as sociated adults, must for the present remain unnamed. For the purpose of this paper, the term 'Macroheterocera' comprises those families included in volumes 10, II and 12 of Seitz, Macrolepidoptera of the World. The collection from Rennell Island consists of 351 specimens representing 83 spe cies. That from Bellona island consists of 37 specimens representing 12 species, eight of which were also collected on Rennell; a further three are recorded from other is lands in the Solomons and may occur also on Rennell and one, Euchromia shortlandica niphosiicha Fletcher, is a distinct race of a species so far recorded from Shortland, Bougainville and Guadalcanal Islands. As will be seen from the accompanying distribution table, the greater part of the species occurring on Rennell and Bellona Islands appear to have reached there either from the west, via the Louisiade Archipelago, or from the north-west via the Bis marck Archipelago and other islands of the Solomons group, for 55 of the 87 species are either identical with or races of species with principally a westerly distribution; a further 11 are either identical with or races of species that are so far known only from the Solomons. Only eight species, or 9 ° „ of the total, have a distribution which extends principally or solely eastwards from the Solomon Islands. There are thirteen species which are so far known only from Rennell Island. The colour names used in the descriptions are taken from R id g w a y , ‘Color Standards & Color Nomenclature’.

Bellona 1., Matahenua, 29-30. xi. 1953, (J. D. B radley), 8 q\ 14 ? including holotype & allotype. Similar in size and in the structure of both male and female genitalia to E. s. shortlan dica Swinhoe (1905) but differs from it in the fore wing, where the basal hyaline spot is minute, and in the abdominal markings, the second and third segments being edged posteriorly with white. The nominate subspecies occurs on Shortland, Bougain ville and Guadalcanal Islands. ARCTllDAE NOLINAE Celama aroa B. Baker ?subsp. Celama aroa B. Baker, 1904, Novit. zool., 11: 414, pi. 5; 39, 41. Celama murina Rothschild, 1916, Novit. zool. 23: 322. Syn. nov. Onengaguga, 1 ?. Distribution; New Guinea; Louisiade Arch.; Bismarck Arch. The genitalia of the single female differ slightly, perhaps only individually, from those of the allotype of aroa and the holotype of murina in the shape of the signum on the bursa copuiatrix. In all three specimens the signum is serrate-edged on one side;
