likely addition, since the rest of the Indo- Australian representatives of it are 

 mostly Indian or Australian ; a very few species are Malayan, and only two 

 or three are known to occur in New Guinea and its satellite islands. Specimens 

 of a member of the section Hemipogon — H. simplex Warren, 1899 (Louisiade 

 Archipelago) — have recently been received from Dampier I. and New Hanover ; 

 this species has very close relatives in H. lividula Warren, 1903, of New Guinea, 

 and H. liparota Turner, 1908, of Queensland. The type of Warren's Thysano- 

 tricha—T. ziczacata Warren, 1903 — is from the Solomon Is. (Isabel I.). That 

 of Meyrick's Mnesterodes — M. trypheropa Meyrick (New Guinea), = P. angusti- 

 pennis Warren, 1897 (N. Queensland), = A. ? jioccosa Pagenstecher, 1900 (New 

 Britain) — reaches in one direction to Timor, and I am under the impression that 

 I have seen specimens of it from Fiji ; it would not be surprising if it proved 

 to occur in the Samoan group. The somewhat isolated species S. rhipistis, on 

 which Meyrick founded his genus Pythodora, is at present only known to occur 

 in Fiji.

 Archipelago ; St. Matthias ; Bismarck Archipelago (New Hanover) ; Solomon 

 Is. Probably S. (L.) uniformis Warren, 1896 (Queensland), and S. (E.) 

 perspersata Warren, 1897 (Timor) will also prove to be forms of this insect, in 

 which case the oldest name for the collective species will be S. uniformis. 



Apparently rather variable. The Samoan form seems rather larger and 

 paler than the Solomons type, and more yellowish than rufous. The New 

 Hebrides example is larger still and sharply marked, but has more typical 

 colouring. 



Since this species (besides S. uniformis and S. perspersata) was described 

 from the which seems much the commoner sex, it is desirable to add a note 

 on the structure. Antennal ciliation of <$ scarcely 1, hind tibia rather long,
