Watson says T. hana is a synonym of T. hecabe after examining the 

 type specimens in the Indian Museum, Calcutta. 



221. Terias andersonii, Moore. 



A single male example was captured at Mussoorie. This is the 

 most westerly point from which we have obtained this very distinct 

 species. Dr. Butler (1. e., p. 70) says that it is inseparable from 

 T. excavata, Moore, which is a dry-season form of T. suava, Boisduval, 

 but he has not seen the type specimens of T. andersonii. 



222. Terias libythea, Fabricius. 



This is very common in our area, we obtained five specimens from 

 Mussoorie and twenty-five from the Dan of the dry-season form, 

 typical T. libythea, of which T. rubella, Wallace, is a synonym, and 

 six from Mussoorie and eleven from the Dun of the wet-season forrm 

 T. drona, Horsfield, of which T. senna, Felder, is a synonym. These 

 Western Himalayan specimens do not appear to call for any special 

 remarks, they are quite normal. 



223. Terias venata, Moore. 

 A single male only obtained at Mussoorie. 



224. Terias l^eta, Boisduval. 



Recorded from " Landoor " by Butler. No specimen of the typical 

 rainy-season form, which has the underside deep rusty-red, has been 

 obtained in our area, but we have one specimen from Mussoorie of the 

 drier season form, T. jcegeri, Menetries, which has the underside flesh- 

 coloured, and one from Mussoorie and three from the Dun of the still 

 drier season form with the underside yellow, which Capt. Watson 

 identifies as T. vagans, Wallace. In the Dun it is extremely common 

 in November and December. 



225. Comas fieldii, Menetries. 



Very common in Mussoorie from February to November, especially 

 so in March. The female has been observed ovipositing on Indigofera 

 Dosua, Ham., var. hetherantha, Wall., Natural Order Leguminosce, 

 The butterfly is found in the Dun in every month except the three 

 coldest. 



226. Colias erate, Esper. 



Not rare in Mussoorie from March to May. A white dimorphic form 

 of female is also found rarely. It ia scarce in the Dun in the early 

 spring.
