and abdomen tinged with steel-blue, which also extends to the base 

 of the fore wings. Hinder part of abdomen clothed with some 

 scattered white hairs. The haustellum bright red, looking, when 

 rolled up, like a red spot below the neck. 



Of this curious and distinct species I received two specimens only, 

 from the late Otto MoUer in 1887. As they have neither date nor 

 locality, I presume they were taken in the interior of Sikkim by his 

 native collectors. 



Retina? fuscescens. (Plate XXXII. fig. 12, $ .) 



Of this very distinct species I have a single specimen only, of 

 which the antennae are not perfect and the wings somewhat worn ; 

 but though I cannot be certain of the genus, yet the insect can be 

 confounded with no other known to Mr. Moore or myself from the 

 Indian region \ 



The venation seems near that o{ Retina rubrivitta, though in this 

 family I do not attach so much importance to that character. Tlie 

 antennae are somewhat less pectinated though similar in structure. 

 The projecting organ which resembles an ovipositor, and the red 

 neck and the character of the wing-scales, all tend to prove that it 

 belongs to the Chalcosiidse, though its superficial appearance might 

 lead one to place it among the Lithosiidae. 



Colour dull black, with a large whitish patch from the base to 

 beyond the middle of hind wing. Tip of fore wing and costa of hind 

 wing below also whitish. Collar and shoulders beneath red. Htad, 

 legs, and body black. 



Expanse 33 mm. 



Described from a single specimen taken in the interior of Sikkim 

 by one of MoUer's collectors. 



Retina? flavicosta, n. sp. (Plate XXXII. fig. 1, $ .) 



Of this insect I had a single female in the same collection as the 

 last. It seems to be most nearly allied to R. rubrivitta, Wk. Cat. 

 Het. ii. p. 439 (1854) ; Butl. 111. Het, v. p. 25, t. 84. fig. 4. 



Fore and hind wings dull black, with the costa of hoth wings and 

 outer margin of hind wing dull yellow ; collar and sides of neck 

 below crimsou. Thorax and body apparently tinged with green, but 

 the specimen is too much rubbed to be certam ; antennae wanting. 



Genus Elcysma, Butl. Trans. Ent. Soc. 1881, p. 4. 



Elcysma dohertyi, n. sp. (Plate XXXIV. fig. 4, J .) 



This remarkable species is very nearly allied to E. westwoodi, 

 VoU., from Japan, which is figured in the Tijdschrift for 1863, t. ix, 

 fig- 3, <S , and described at page 136, of which E. translucida, Butl., 



^ After describing this species I saw it in Pr. Staudinger's collection, and 

 found that it was the same as Sorifia fuscescens, Moore, Atk. p. 1(5 (1879). The 

 male differs in having the hind wing without white, only a paler brown in the 

 centre, and in being smaller. The antennas are very long, measuring -40 of an 

 inch, which is the same as the length of the hind wings. Both sexes are in 

 the Atkinson collection.
