NOVITATES ZOOLOGICAE XXIII. 1916. 3 



Walk. [— galactina Th.-Mieg), which is only known from Celebes, the Sula 

 Islands and Ceram. dentifera inhabits N. India, Hainau, Formosa and Talaut, 

 and the three may be regarded as representative species, but I think have passed 

 beyond the stage of subspecies. 



6. Derambila strigicosta brunneicosta subsp. nov. 



Differs from D. strigicosta strigicosta Warr. (from New Guinea and its satellite 

 islands) in several particulars, which perhaps indicate even a separate species. 



Forewing with apex in <? perhaps slightly more produced ; costal area suffused 

 with light brownish, recalling that of lumenaria Hb. ; discal dot small (in 

 strigicosta strigicosta always large), spots larger, more inclining to become con- 

 fluent ; terminal spots light brown, not black. Hindwing with the postmedian 



line and terminal spots showing the same distinctions.

 S. Christoval. Type from S. Christoval, April 19-29, 1908 (A. S. Meek) in 

 coll. Tring Mns. 



7. Callipotnia allognota sp. nov. 



o ? , 37-41 mm. Closely similar to the two already known species ; distal 

 margin of forewing (especially in the ? ) slightly more sinuate in anterior half, the 

 apex consequently appearing more produced. The dark colouring and the sharp 

 angulation of the line of the hindwing (though this is generally not quite so strong 

 beneath) recall angidifera Prout {Nov. Zool. xx. 394), but the elbow in the post- 

 median line of the forewing is rounded, nearly as in multicolor Warr., though not 

 quite so broadly. The projection in front of R 1 of the forewing is more acutely 

 pointed than in either, and the discal spot of this wing generally much larger. The 

 hindtibial hair-pencil of the $ appears to be less strong thau in the other species, 

 but is ensheathed in both the examples. But the most definite structural difference 

 which I have discovered in the three species is in the hairy clothing of the $ 

 hindwing beneath, and is as follows : 



multicolor Warr. Much reddish hair at base ; a long dark tuft on M proxi- 



mally to origin of M 2 ; shorter, brownish hair on M distally and at base 



of M 1 , also on SM 2 . 

 allognota Prout. Less strong reddish hair at base; no long dark tuft on M, 



the short brownish hair stronger, encroaching into cell, between SM 3 and 



fold, etc. 

 angidifera Prout. Nearly as the preceding, but with strong brown, partly 



red-mixed clothing on distal part of SC and base of SC 2 and R 1 .

8. Alex ochracea sp. nov. 



Closely akin to palparia Walk., of which it might almost be regarded as a 

 subspecies except that the c? antennal pectinations are appreciably longer. Ground- 

 colour brighter ochraceous, the oblique transverse line always well developed, the 

 dark irroration rarely so strong as in palparia, a narrow clear area always persisting
