GEOMETRIDAE.

tlie rest are entirely Indo-Australian, mostly inhabiting the islands. C. ghosha 

 Walker has a race (C. sticticata Warren, Nov. Zool., ix, 361, 1902) in the Solomon 

 Is. ; C. elongata Warren (Nov. Zool., ix, 360, 1902), and C. purpurilita Prout 

 (Nov. Zool., xxxii, 41, 1925) were described from specimens from that group ; 

 the Bismarck and Louisiade Archipelagos also provide forms. 



14. Collix lasiospila (Meyrick). 



Cidaria lasiospila Meyrick, Tr. Ent. Soc. Lond., 1886, p. 194 (Fiji). 

 Tutuila : Pago Pago, 1 12.viii.1925. 



Rather larger than the only Fiji specimen I have seen (a $ in the British 

 Museum) otherwise identical ; not so large as the <$ type in coll. T. P. Lucas, 

 according to the measurements given by Meyrick. The determination is only 

 conjectural, since Meyrick does not describe the very distinctive under side, 

 on which the veins are broadly yellow ; but I know no other similar Fijian 

 Larentiid to which his description could be applied. Meyrick adds, however, 

 that the same species occurs in Australia, and that there may be some error 

 as regards the locality ; but, since there is nothing in his Australian " Revision " 

 (Proc. Linn. Soc. N. S. Wales, Series 2, Vol. V, pp. 791-879, 1891) to throw light 

 upon it I cannot pursue the matter further. Similar, though not identical, 

 species do occur in Australia. 



Eupithecia Curtis. 



Brit. Ent., ii, 64, 1825.— Tephroclystia Hiibner, Yerz. beh. Schnett., 323, 1826 ; Meyrick, Tr. 

 Ent. Soc. Lond., 1892, p. 65 (TepJiroclystis, ex err.) ; Hulst, Tr. Amer. Ent. Soc, xxiii, 265, 

 1896 (Tephroclystis, ex err.) ; Staudinger and Rebel, Cat. Lep. Palaearct. (i), 308, 1901 ; 

 Warren et al., passim. 



In its more typical forms Eupithecia, perhaps the most extensive Geometrid 

 genus in the world, does not concern us here. It occurs almost everywhere 

 in the Palaearctic, Nearctic, Neotropical and Ethiopian Regions, and has a 

 good many representatives in India and perhaps parts of Malaya. But in the 

 Moluccas and New Guinea it seems to be very sparsely represented or almost 

 absent, except for a few specialised offshoots which may claim generic separa- 

 tion. Among the latter is Mnesiloba Warren, with double areole, as in the 

 section Eucymatoge Hiibner, but having in addition a hind wing specialisation,
