name ; and C. decisaria Walker (Ceram) =C. callicrossa Meyrick (New Guinea) 

 = C. lacteata Warren (New Britain). The former has a race or exceedingly 

 close ally in Fiji, and it will not be at all surprising if both it and C. decisaria 

 are also found in Polynesia. I have before me a of a probable race of C. 

 decisaria from Lifu, and a small worn (apparently more typical) from the New 

 Hebrides, the latter presumably the $ of C. psycJiastis Meyrick (vide supra). 

 Warren named several aberrations from the Kei Is. (Nov. Zool., v, 430, 1898), 

 and one from the Solomon Is. (Nov. Zool., xii, 432, 1905) ; westward the species 

 reaches Borneo and Java (Mt. Gedeh), and I have even seen one specimen from 

 Penang. 



The Samoan and other Polynesian Cleora belong, I suppose, to the same 

 subgroup as C. injectaria and C. decisaria, and, on McDunnough's antenna! 

 character, would not be quite so strictly congeneric with C. cinctaria as the 

 alienaria subgroup. They have still longer and more lax pectinations, which 

 tend to curl irregularly round the shaft, and the slender secondary pectinations 

 have disappeared — at least so far as can be determined without laborious 

 anatomical research. I cannot see, however, that this difference is correlated 

 with any other structural one ; all the African species have the antenna! structure 

 of the Polynesian, etc., while several of the Indo-Malayan — C. alienaria Walker, 

 €. gelidaria Walker, C. determinate Walker, C. concentraria Snellen and some 

 unnamed species together with the Australian C. illustraria Walker and the New 

 Guinea C. hospita Prout — have the doubly bipectinate antenna of C. cinctaria 

 Schiffermuller. It should be added that the very common C. inflexaria Snellen, 

 which is an outlier of the present group and occurs in most localities from Malaya 

 to the Solomon Is., shows variable and often asymmetrical antennal conditions 

 similar to those noticed by Turner (Tr. Roy. Soc. S. Austral., xxviii, 230, 1904 ; 

 Proc. Linn. Soc. N. S. Wales, xlii, 333, 1917) under " Ectropis " hemiprosopa 

 Turner and " E." camelaria Guenee, except that in that group (the genus Catoria 

 of Moore) the geminate branches are of approximately equal width, whereas in 

 Cleora inflexaria one branch is extremely slender, as in C. cinctaria. This 

 species (C. inflexaria) will perhaps be found to inhabit Polynesia also, and it is 

 not impossible that one or more representatives of Catoria may likewise be 

 discovered there ; both the white group (camelaria group) and the green (delectaria 

 [Walker] group) are very widely distributed, and reach the Bismarck Archipelago 

 and the Solomon Islands.
