feet elevation. It flies slowly among dense herbage near the ground in the shade. 

 The form described as Eamdeo is considered by Mr. Otto Moller only as a second 

 brood of Diores, which he gets from April to June, whilst Ramdeo occurs later in the 

 year, from about August to October." Dr. G. Watt obtained specimens during his 

 journey to Manipur (Butler, Ann. N. H. 1885, 302). Numerous specimens in 

 Colonel C. Swinhoe's collection were taken in the Khasia Hills by the Rev. W. 

 Hamilton's native collectors. Major 0. H. E. Adamson (List Burmese Lep. 10) 

 obtained it " not uncommon about Bhamo in the cold season. One specimen also 

 taken in Arakan." Mr. Elwes (P. Z. S. 1891, 271) records its capture by Mr. AV. 

 Doherty, but not abundantly in the Karen Hills, East Pegu. Mons. G. A. Poujade 

 (Nouvelles Arch, du Mus. Paris, 1892, p. 264) records it from Luang Prabang, 

 Laos.

Imago. — Male. Wings large, broad, short. Forewing subtriangular ; costa much 

 arched, apex obtusely rounded, exterior margin almost erect, even ; posterior angle 

 rounded; cell very broad; first subcostal branch emitted at one-fiffh before end of 

 the cell, anastomosed to the costal for some distance before its end and touching the 

 base of the second subcostal just beyond its base ; second subcostal emitted at two- 

 thirds beyond the cell ; discocellulars long, outwardly-oblique and slightly concave 

 in the middle ; radials from slight angles near upper end of discocellulars ; middle 

 median veinlet emitted at a short distance before end of the cell, upper median 

 obtusely arched beyond the cell. Hindvnng with the apex rounded, exterior margin 

 oblique, anal angle slightly produced ; first subcostal branch emitted at from half 

 length of the cell area, second at an equal distance ; upper mediau veinlet much bent 

 beyond its base, the angle approximating closely to the radial (third subcostal) ; 

 cell open ; submedian vein straight ; internal vein long ; on the upper side there is a 

 iiacreous-hordered narrow glandular ^tatch of scales situated above the base of the sub- 

 costal, the patch being overlapped by a lengthened tuft of long erectile hairs extending 

 from below the base of the subcostal; and within the cell there is a large black glan- 

 dular patch of raised scales, which occupy the upper middle of the cell, this latter 

 patch is not nacreous-bordered. On the underside of the forewing, the basal area 

 below the median vein is broadly nacreous and has a very small patch of dull silvery- 

 scales below the submedian near its base. Body robust ; thorax woolly ; head large, 

 with a small pointed frontal tuft ; eyes prominent, large, naked ; palpi nearly erect
