Hiiuhvhig : browner, with black speckling ; tlic inuev margin grey ; the tuft 

 of inner margin yellowisli. 



Underside withont markings, grey with a brownish tinge. 



Face and palpi blackish ; vertex, thorax, and abdomen grey. 



Expanse of wings : '11 mm.

Intermediate between T. geminipunrta and inonmta Warr. The mitline of the 

 wings as in the latter : the forewing, however, has no rough hairs at anal angle, 

 along veins 1 and 2, nor is vein 2 curved downwards ; Jhe hindwing beneath has 

 no rough grey hairs towards anal angle, but, as in geminipiincta, a patch of rust- 

 brown scales in the furrow. But for this and the traces of the central fiiscia on 

 forewing it might easily be mistaken for inonnitn.

I find that the ueuration in these two genera is the same ; veins 7, 8, 9, lU are 

 always stalked, but the course of 10 l)efore anastomosis with 11 is so short as 

 easily to be overlooked; 11 anastomoses strongly with 12, lo generally anastomosing 

 with 11 and 12 coincidently before the separation of the costal portions of these two 

 veins, which run close together; subsequently lu anastomoses with 8, 9. Neither 

 are the palpi different ; their superficial appearance varies according to the position 

 assumed in death. The species subpiirpurea Warr. must therefore be transferred to 

 Leptoctenopsis. 



8. Racasta caberaria AVlk. 



This species has hitherto generally been sunk to Guenee's t^pntiario, but, as far 

 as I can judge, incorrectly. Guenee states that in the forewing of his species the 

 four lines do not reach the costa ; but in caberaria they traverse the forewing as 

 completely as the three lines of the hindwing. As far as description goes, the two 

 species are better kept separate, following Druce, who, in the liiologia, ii. p. 123, 

 quotes Walker's species cab<-raria, Init not Guenee's. Dogniu's extendata will in 

 this case, 1 think, sink as a synonym of caberaria.
