none of the nervular bands of primaries continued to the cell ; 

 the nervular brown streaks of secondaries also continued 

 nearly to base of wings. 



Family Erateinidae. 



Genus 21. Erateina, Doubleday. 



34. Erateina latipennis, n. sp. B.M. 

 Primaries above as in E. undulata^ but the transverse yellow 



band reduced to a line ; secondaries very similar to E. undu- 

 lata, but broader, with central band deep orange instead of 

 red, and much broader : below somewhat similar to E. undu- 

 lata, more orange in tint, with narrower central transverse 

 band ; the silvery area reduced to a narrow squamose streak 

 limiting a broad subbasal chocolate band ; the discal yellow 

 band much widened, especially on primaries ; the area between 

 subbasal and discal bands orange ; fringes varied with orange 

 instead of pale yellow. 



Expanse of wings 1 inch 8 lines. 



35. Erateina cometaris, n. sp. B.M. 

 Nearer to E. Necera than to any other described species. 



Wings above with basal half greenish cinereous, with bronzy 

 reflection, apical half black; primaries with central abbre- 

 viated, broad, white, oblique, hyaline band : secondaries with 

 central white streak, obsolescent towards costa ; a subanal 

 crimson spot; fringe alternately black and white. Wings below 

 plum-coloured ; nervm-es of basal area and two oblique central 

 bands, broadest on primaries, silver, an oblique transverse 

 discal streak gold ; primaries with internal area silver, outer 

 central band hyaline in the centre ; secondaries with golden 

 discal streak abbreviated, disappearing as it reaches outer 

 central band ; fringe alternately black and white. 

 Expanse of wings 1 inch 7 lines. 



36. Erateina discalis, n. sp. B.M. 



Primaries above black, basal area and a trifid hyaline spot 

 crossing median branches and end of cell snow-white ; costal 

 and subcostal nerviu-es red ; secondaries snow-white, a broad 

 marginal black border, fringe alternately black and white. 

 Body black, thorax clothed with whitish hairs ; abdomen 

 white-banded above, white below, with lateral series of red 

 spots ; head white, front and antenna? red, palpi and legs black 

 and white. Primaries below plum-coloured ; internal area and 

 central transverse band silvery white, the band liyalinc in the 

 centre ; basal half of costa irrorated with orange ; the base and
