Show 1892.] LEPIDOPTERA FROM SANDAKAN. 121 wallaceana 3 > Butl., Narathura pryeri, n. sp.1, N. achelous $ var., Hew., Papilio prexaspes, Feld., P. evemon, Bdv., P. telephus, Feld., P. bathycles, Zinck., P. arycles, Boisd., P. agamemnon, Linn., Astictopterus sindu, Feld. HETEROCERA. Amongst these are several beautiful new insects, as well as others which are by no means abundant in collections. No Sphingidce are represented, but there is a lovely new Zygcenoid Arctiid. CHALCOSIID^E. MlLLERIA FICTA. Cyclosia ficta, Walker, Journ. Linn. Soc. vi. p. 97 (1862). Milleria pontioides, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. vii. p. 35 (1881). Walker's description of this species is so bad that without examining the type it would be quite impossible to guess at its identity with M. pontioides. CALLAMESIA STRIATA. Amesia striata, Druce, Ann. & Mag. Nat. Hist. ser. 6, vol. vii. p. 142(1891). This species appears to be allied to C. submaculans of Walker (Journ. Linn. Soc. iii. p. 185, I860). I have to thank Mr. Druce for identifying it for me as his species. CHALCOSIA INDISTINCTA. Chalcosia indistincta, Swinhoe, in litt. One imperfect female. * ARCTIID^E. MYDROTHAUMA, n. gen. Nearest to Eupyra, the primaries a little narrower, the subcostal branches emitted regularly from the cell instead of branching off from the main nervure; the second and third median branches wider apart at their origins ; the secondaries with strongly arched costal margins; three instead of two median branches; palpi extremely short and porrected, instead of very long and almost erect; tibial spurs also very short; abdomen much broader, flattened and tufted at the sides. From Mydrodoxa, to which it is also allied, it differs in its considerably narrower primaries with sinuous instead of arched inner margin ; in the important point of 1 Differs from N. amphimuta, to which it is allied and which it nearly resembles on the under surface, in its much inferior size and in the deep glistening ultramarine (rather than violet) blue colouring of the upper surface ; the female, which is in the B.M. from Sarawak, has a much more restricted blue area, especially on the secondaries: expanse of wings, 3 43 millim., $ 40 millim. |
