reaching the margin, but does not actually anastomose with either of them. The anastomosing 

 of the iirst subcostal with the costal occurs in all the species I have seen, but Mr. Distant 

 tells me that it does not do so in T. orphne, Butler, which occurs in Borneo. 



The cell in both wings is open as in the typical group of Euthalia, the body is small 

 and weak, the wings rounded at the apex, giving the insect a weak appearance as in E. lepuiui 

 and allied species. "This genus is much smaller in extent than i^wZ/wZ/rt, and likewise has 

 a different distribution, for whereas that genus may be said to have its head-quarters in 

 North-Eastern India, Tanaecia is almost confmed to the Indo-Malayan region, and is 

 apparently absent from Continental India and Ceylon, though found in the Andaman 

 Islands." (Distant, I.e.) A single species occurs within our limits, and very much resem- 

 bles in both sexes the female of Euthalia acontius, being dark brown above with the usual 

 Euthahad basal markings, both wings crossed by a prominent white discal band, the 

 underside washed with pale green almost throughout. 



At least seven species occur in the Malay Peninsula, the descriptions of them will be 

 found below.* Some of them are allied in colouration to the blue-banded group of 

 Euthalias of which E. andersonii is the Indian representative, the others more nearly resemble 

 the females of E. jahnu, &c.

Expanse: $, 2-12 to 3-10; ?, 3-1 to 3-5 inches. 



Description : "Female. Upperside dark rufous brown. Both 2viugs with the usual spots 

 in and below the cell : both crossed beyond the middle, from the costal margin of the fore- 

 wing to the anal angle of the hindwing, by a broad band of white divided by the nervules 

 sinuated deeply on its inner margin at its fourth spot, bordered outwardly by a series of 

 hastate black spots crowned with lilac. Foreiving with a small white spot between the band 

 and the apex. Underside pale green. Both wings with the bands and spots as above, bordered 

 inwardly with black. Male like the female, except that the white band of the hindwino- 

 is narrower, and on the underside bordered on both sides with black spots." 



"This is the largest known species of the T. trigerta group, to which it belongs." 

 (^Hewitson, 1. c. in Ann. and Mag. of Nat, Hist.) T. trigerta occurs in Java. 



7'. a'i^^^iV/V is a common species in the South Andaman Isles. Mr. de Roepstorff sent a 

 single specimen from Nankouri in the Nicobars, but its occurrence there is doubtful, probably 

 the specimen was an Andaman one.
