One ? . R. Jutahi, above R. Curnem, Jan. 24th, 

 1875. 



Very closely allied to Botys (Samea) ebuleaUs, Gn., 

 Delt. & Pyr., 196, 136, but with only the yellow fascia 

 beyond the exterior line reaching the costa. Also akin 

 to Botys matutinalis, Gn., and B. adipalis, Ld., but much 

 smaller than either. 



97. Hapalia pallidipennis, n. s. 

 Fore wings semihyaline, whitish, with a faint yellowish tinge, 

 with the costa concisely and the hind margin broadly and diffusely 

 bronzy grey ; the lines brownish ; the first curved, the exterior 

 sUghtly denticulated, but not bulging outwards in the middle of its 

 course as in B. detritalis. A very strong brown lunular mark on 

 the disco- cellular, and a minute dot immediately beyond the first 

 line representing the orbicular stigma. Hind wings like the fore 

 wings, bronzy grey along the hind margin, with a distinct central 

 brown spot, and the exterior line of the fore wings repeated. All 

 the fringes with a bright Une at their base, followed by a darker 

 one, beyond which they are lighter, and in the hind wings white. 

 Head, thorax, abdomen, and legs whitish ochreous ; abdomen with 

 a darker ochreous anal tuft, the last segment wholly blackish 

 above, the two preceding segments blackish only at the sides ; the 

 second segment with a black dot above. Under side of the abdo- 

 men glossy white. Expanse of wings, 25 mm. 



One <y , from R. Jurua, Nov. 7th, 1874. 



Very closely related to B. detritalis, Gn., but purer 

 white, without the yellowish colouring ; also to B, 

 rhipheusalis, Wlk., from Borneo. 



98. Hapalia sublutalis, n. s. 

 Wings greyish ochreous, with a pale bronzy or purplish tinge ; 

 semihyaline ; the ochreous scaling denser along the costa, inner 

 margin, and hind margin, the latter also greyer ; fringes con- 

 colorous, shining. There are no clear markings of any kind, but a 

 short basal and a curved exterior line are sometimes faintly 

 perceptible, and there is a darkening above the disco-cellular, but 

 not a distinct spot. Head, thorax, abdomen, and legs ochreous, 

 glossy ; in the ^ the anal tuft contains some darker hairs. Under 

 side without markings, glossy ochreous-grey. Expanse of wings, 

 33 mm, 



Six examples. Three males and three females ; the
