banded below middle aud at apex with dark fuscous (tarsi broken). 

 Fore wings cleft from before middle, segments linear; ochreous- 

 brown, costa and 1st segment darker brown ; a moderately large 

 black dot beneath costa near base, another in disc at one-third, and 

 a third on 1st segment at base ; 1st segment with a few ochreous- 

 whitish scales before middle and towards apex, intervening space 

 suffusedly dark fuscous ; costal cilia fuscous, becoming whitish 

 before middle and towards apex ; rest of cilia light greyish ochreous, 

 on lower margin of 1st segment somewhat mixed with whitish, 

 with a spot of black scales beneath apex, on upper margin of "ind 

 segment with a white spot before middle, some black scales 

 towards middle, and tips white at apex, on lower margin of 2nd 

 segment with a broad dark grey blotch before anal angle, bordered 

 on each side with a whitish bar, and a small apical spot of black 

 scales. Hind wings cleft firstly from before one-third, secondly 

 from base, segments linear ; dark fuscous ; cilia ochr ecus-grey, 

 3rd segment with a spot of black scales on inner margin at three-

Principally distinguished fiom T. coDipsocliares, with 

 which it agrees in neuration, by the conspicuous black 

 subcostal and discal dots ; there are also some other 

 slight comparative differences ; but I think it not unlikely 

 that the discovery of forms from intermediate localities 

 may show that these two are only geographical races of 

 the same species.
