BUTTERFLIES. 125 



58. Lethe (Zophoessa) sura, Doubleday and Hewitson. 



I have taken this species in the Birch Hill Park, Darjeeling, in 

 October ; it is found from 5,000 to 8,000 feet in forests from June to 

 November, and is rather common. In May it swarms on the dark 

 forest roads in Baling, and is always found at a higher elevation than 

 L. dura^ Slarshall. 



59. Lethe (Zophoessa) dura, Marshall. 



The type specimen was ticketed by Colonel G. F. L. Marshal], r.e., 

 "Lower Thoungyeen forests, Upper Tenasserim, May." I cannot help 

 thinking that there is some mistake with regard to this locality. No 

 other species of Zophoessa is known to occur in Burmah at practically 

 the level of the sea; the type specimen is unique, and its capturer, 

 Major C. T. Bingham, has never obtained a second specimen, though 

 during the last ten years he has collected over and over again througli 

 these forests. The type specimen agrees absolutely with examples 

 from Bhutan, and my impression is that it came from thence and not 

 from Burmah. Anyhow, Mr. Moore's Zophoessa gainmiei (Lepidoptera 

 Indica, vol. i, page 294, pi. xci, fig. 3, male, 1892), from Bhutan, is an 

 absolute synonym of Z. dura. Mr. Moore had only the original des- 

 cription and figure of Z. dura to guide him when he described 

 Z. gammiei. He may have been further misled by Mr. Llwes' figure 

 of this species, which was taken from a female example, not from a 

 male as stated. Other synonyms are "i?ci«s" inoujnnensis, Poujade, 

 and Zophoessa lihitina, Leech, from Western and Central China. 



Z. dura is a somewhat rare species, and has been obtained by 

 native collectors in Bhutan in September, and by Mrs. Wylly at 

 Kalimpong. It is local and swarms in May on the Nim ridge in 

 bamboo jungle at an elevation of 4,500 to 5,000 feet. It has the same 

 habits as L. sura. 



60. Lethe (Zophoessa) goalpara, Moore. 



Native collectors bring in this species in thousands. It occurs in 

 the interior at from 6,000 to 8,000 feet. Mr. G. 0. Dudgeon has never 

 noted a specimen from east of the Tista river or from Bhutan. Nor 

 have I seen a female, though I have constantly looked for it amongst 

 the numerous males that have passed through my hands. 



61. Lethe (Zophoessa) atkinsonia, Hewitson. 



Occurs at high elevations, 8,000 to 9,000 feet, in July and August. 

 It is not common, but occurs throughout Sikhim and lihutan as far 

 as the Saukosh river. 



62. Lethe (Zophoessa) elwesi, Moore. 



Occurs commonly on the Singalela range from 9,000 to 12,000 

 feet elevation in July and August. Mr. Moore considers this 

 species to be sufficiently distinct from the Western Himalayan form
