Isosauris gen. nov. 



Near Pacrophylla Blanch., but dififering in the following j)oints : — antennae in 

 both sexes simple, not thickened; hindwings in d without additional inner lobe; 

 hindwing,-. in both sexes with one uervule absent (jirohably the third median), the 

 radial starting from the transverse vein halfway between the centre and lower end of 

 cell; in this re.spect, it probably approaches 7?/toj)a^orfe« Guen., though Guenee says 

 that in that genus it is the independent that is wanting. 



Tyjie : Isosauris hastigera Butler (Oporabia). 



Toxopaltes gen. nov. 



Distinguished from Tomapteryx Philippi, in having no cleft and additional lobe 

 in the hindwiugs ; but the hindmargin of the hindwings is produced in the middle 

 as a sharp point, with the margin on either side curving away, just as in Holwista 

 Warr., from India. 



Type: Toxopaltes hotidata PVld. {Tomoptery.r). 



Triptila gen. nov. 



Distinguished from Rhopalodes Gueu. by the presence of a distinct radial to the 

 hindwing, which Guenee expressly states to be absent in that genus ; distinguished 

 from Toiiiopteryx Philippi bv the absence of the cleft in the hindwings ; characterised 

 positively by the possession of a very large superincumbent lobe on the hindwings. 



Type : Triptila virescens Philippi {Tomopt&ryx). 



f^riiFAMiLY KUCKSTIINAE. 



Carsia perelegans sp. uo\-. 



Allied to plag lata Linn., which occurs also in Afghanistan and India; but the 

 transverse bands are finer and paler; the whole ground colour is more pinky; in 

 particular, the exterior line which forms the outer edge of the middle field is much 

 less sharply angulated. There is no trace of dark or black at the rise of the lines on 

 the costa, nor in the apical streak. 



Expanse of wings : 34 mm. 



Several examples from Japan. 



Docirava affinis ( 't ) .sp. nov. 



Closely allied to D. vastata "VMk., from India, of which it may be merely a local 

 form, but the difference is constant. The two pale lines across the forewings are more 

 slender ; the central fascia formed by these lines is not edged within the lines by a 

 broadly darker shade. 



A long series from Central China aud two from Japan. 



Lissopsis gen. nov. 



A South American genus, allied to J/a7-//to/)<c?-?/.(; Pack., from North America, and 

 to Siona, of Europe. Distinguished by the very fine, smooth scaling, and especially 

 by the antennae of the <?, which are densely and shortly serrate. 



Type : Lissopsis columba Butler {Siona).
