344 Wood- Mason & de Niceville — 0?i the Bhopalocerous [No. 4, 



by any entomologist, and nothing identifiable with which has been ob- 

 tained by Mr. Wood-Mason. 



From the Independent State of Manipur, which bounds Cachar on 

 the east and is separated therefrom by a range of lofty and precipitous 

 mountains, Mr. Butler has recorded (Ann. & Mag. Nat. Hist., 5th 

 series, vol. xvi, p. 298, 1885) 114 species, many being described as new, 

 and many being from the hills, while all, save a few from Nemotha (a 

 trigonometrical peak 3,634 feet high at the extreme south of the high- 

 lands of the district), of those enumerated and described iu the follow- 

 ing pages were caught in the lowlands of Cachar on either side of a line 

 running nearly directly north and south from the peak just mentioned to 

 Kupacherra close to the Lushai frontier, between 25° 1' and 24° 24' 

 north latitude and between 92° 40' and 92° 52' east longitude, approx- 

 imately, chiefly in the forests of Silcuri, Durgakuna, Dhurmkhall, Sildubi, 

 Irangmara, the Doarband-pass, Hasooria or Lalla Mookh, and Rupacherra 

 betw^een the Barak Biver and the Lushai frontier, and at Dooloo and 

 Subong north of the Barak near the foot of the N. Cachar Hills. 



247 species were obtained, affording a good indication of the rich- 

 ness of the region in insect life ; but large though this number is — the 

 largest probably that has as yet been published for any portion of India 

 of equal extent — there is little doubt that it might be increased by at least 

 a hundred by an enthusiastic collector stationed in the district for a few 

 years. 



The collection, which was formed between March 26th and October 

 4th, is remarkable for its richness in species of the family HesperiidcB ; no 

 less than 53 distinct species of this interesting group having been obtained. 



This paper was written in 1881, but its appearance in print has been 

 delayed till now by Mr. Wood-Mason's absence from India on furlough 

 and official engagements and by the preparation of the plates, which have 

 only just been completed. 



For an admirable account of the physical features and meteorology 

 of the lovely district of Cachar the reader is referred to the graphic pages 

 of ' A Statistical Account of Assam ' by Sir W. W. Hunter.*
