DiSTEiBUTioN axd Habits. — " Found locally throughout the Himalayas from the 

 Chenab to Sikkim, and extending through the Khasia Hills to Tapper Burma. 

 Major Marshall has taken it in Ohumba in May and June. Mr. A. G. Young notes 

 it (P. Z. S. 1882, 243) as being a very local insect in Kulu, but, where occurring, 

 abundant. It is to be found in wet ravines at from 3000 to 4000 feet elevation. It 

 is not a rapid flier and is easily captured ; when at rest it may be taken with the 

 fingers. It is constant in its appearance, frequenting the same localities year after 

 year. The imago does not hibernate." Baron Hiigel obtained it at Masuri. Mr. 

 E. T. Atkinson records it from the submontane tracts of Kumaon. Mr. L. de 

 Mceville met with it in Sikkim, in profusion at from 2000 to 7000 feet elevation, in 

 October, the larv« covering the weeds all along the cart-road between Chunabati 

 and Darjiling ; in Simla he only met with it in a limited area of about 200 yards in 

 the bed of a sti'eam. The Indian Museum, Calcutta, has specimens from Bliotan, 

 Sibsagar, the Dafia and Khasia Hills and from Upper Burma" (Butt. Ind. i. 319). 

 We possess specimens from Kashmir (Capt. R. Bayne Reed), Kulu, Dehra Dhun, 

 Nepal (Gen. G. Ramsay), Sikkim, Khasias, Burma, Karen Hills (Sig. L. Fe i). 

 Col. C. Swinhoe has it from Kulu, and also numerous examples from the Khasias. 

 In the British Museum are examples from Simla and Kulu; Shillong, Assam; 

 Nepal ; Sikkim, taken in July and August by Mr. Dudgeon ; Tukvar, Khasias, 4000
