mark on the disco-cellulars; all the lines obsolete. The second is 

 reddish-brown and typical. The third is grey with the waved lines 

 distinct. 



Genus Gunda, Wlk. 

 89. G. javanica, Moore. 

 Sikhim, 1,800 feet (Balasun Valley), August. 



41. G. sikhima, Moore. 

 Sikhim. (Occurs rarely in June. — H. J. E.) 



Genus Theophila, Moore. 



42. T. huttoni, Westw. 



Sikhim, 1,800 feet; Bhutan, up to 3,000 feet. The larva feeds on 

 Morus serrala and other plants. Messrs. de Niceville, Otto Moller, 

 Knyvett, and myself found an orange tree covered with the cocoons 

 of this species, and we preserved a larva, a drawing of which I sent to 

 Mr. Moore. The larvae had apparently fed on an adjoining tree, and 

 only utilised the orange tree to spin their cocoons on. 

 Genus Mustilia, Wlki 

 44. M.falcipennis, Wlk. 



Sikhim, 7,000 to 9,000 feet ; Bhutan. Some specimens are much 

 suffused with bluish-grey. Mr. Elwes remarks that what I call 

 M. sphing if or mis, Moore, may be a second form of M. falcipennis^ 

 which he recognises. He says : — { ' what I call falcipennis differs 

 from the other form in being much paler, especially on the hindwing, 

 so that the transverse bands and the discal spot on the forewing are 

 much more conspicuous ; the thorax is also much paler and the wings 

 less falcate at the point. " My only specimen of M. sphing if ormis, 

 Moore, was identified for me by Mr. Moore, and compares well with 

 his figure. 



45. M. sphing if ormis, Moore. 



Sikhim, 5,500 feet. One female measuring 81 " millimetres in ex* 

 panse. This specimen I reared from a larva. The whole of the thorax 

 and forewing as far as the oblique line from the apex is pinkish-brown, 

 the whole area beyond being chestnut. Hindwing ochreous, becoming 

 chestnut towards the inner margin. Abdomen darker. There are 

 no cell-spots on the upper or under side of either wing, nor is there 

 any grey suffusion.
