than the ground-colour ; the subterrninal obsolescent. Underside of 

 both wings with the pale-reddish areas more irrorated with fuscous 

 than in distincta, and the reddish-golden tones replaced by coppery- 

 red. These last are omitted in Hampson's description, but cover all 

 the fore wing beneath except narrow areas at costa, termen and hind- 

 margin, and are present also in fold and at hindmargin of hind wing.

Differs from the 2 of distincta much as the $ differs from the 

 $ of that species. Underside of hind wing is altogether without the 

 golden hair in fold.

Can be easily distinguished from distincta by the shape of fore wing. 

 Hind wing also appears a little narrower, especially in the 2 . 



This and the following species both differ from distincta Leech 

 (Gonitis distincta Leech, Proc. Zool. Soc, 1889, p. 506, pi. lii, fig. 7 

 [Japan]) in having the termen of fore wing excised behind R 3 and 

 slightly angled at M 2 . They also show no distinct abdominal crest, 

 although the basal segments of abdomen are clothed with rough 

 reddish hair with some dorsal green hair, which may indicate a 

 rudimentary crest. In any case the species are undoubtedly congeneric 

 with distincta, with which they agree exactly in general build and 

 neuration, as well as in colour-scheme and pattern. 



7. Clethrophora gonophora sp. nov. (pi. XIII, fig. 7). 



Shape and abdominal hair as in the preceding species but fore wing 

 slightly narrower and more elongate. 



Differs also in length of segments of palpus ; in angulipennis $ and 2 , 

 segment 2 measures about 2 mm., segment 3 only about 1 mm. ; in 

 gonopliora $ and 2 segment 2 measures about \\ mm. (or at the very 

 outside If mm.), segment 3 measures well over 1 mm. 



$ , 34 — 40 mm. 



Thorax and fore wing intermediate in tone between the other two 

 species ; abdomen reddish-fuscous above, bright scarlet beneath, except 

 for a broad pinkish-grey ventral line — in the other two species the 

 scarlet shade is replaced by orange, which is more vivid in tone in 

 angulipennis than in distincta; hind wing purplish-red, rather paler 

 as well as less coppery in tone than in either of the other species ; the
