■lo. Rhodometra intervenata si>. nov. 



Fffrewinr/s: yellow; the markings blood-retl ; a broad costal streak from base to 

 near before apex ; a liroad obliiiue strii)p from apex towards middle of inner margin, 

 stopping abruptly on submedian fold; a narrow streak along liindniargin ; a liroad 

 streak from base beneath the median vein, another above it not reaching base of 

 wing; a row of short horizontal streaks between the veins, parallel to the obliipie 

 line ; fringe yellow, 



Ifinilwhif/s : cream-colour, without markings. 



Underside of forewings suiTnsed with greyi.sh rosy; the oblique line violet ; of 

 hindwings as above. Head and thorax olive-ochreous, sometimes red-tinged; palpi 

 externally and antennal shaft reddish; abdomen like hindwings. 



Expanse of wings : 'M) mm. 



Two Jc?, one ?. from the Escaqjment, British East Africa, February IDOI 

 (Doherty). 



Quite distinct from any forms of ^i". sacrarin L. ; the outer line is nearer llie 

 hindmargin and runs into the apex itself. 



Synthalia gen. nov. 



Fareivings : triangular; costa arched at base, then straight; apex prominent; 

 hindmargin obliquely curved. 



Hindwings: with hindmargin produced at middle, forming a blunt elbow. 

 Antennae of J subserrate, rasped above ; palpi short ; tongue and frenulum present ; 

 hitidtibiae with four spurs. 



Neuration: forewings, cell two-fifths of wing; discocellular obliquely curved; 

 first median nervule at three-fourths, second close liefore third; lower radial from 

 sliglitly above centre of discocellular. upper from upper angle of cell ; all five sid)- 

 costals stalked from before end of cell : hindwings, costal and subcostal anastomosing 

 for two-thirds of cell ; 6, 7 and 3, 4 stalked. 



Type : Synthalia intiocens sp. nov. 



The single species reminds one of some species of Am(turii)ia. 



4(i. Synthalia innocens sj). nov.

 respectively, both angled below costa, the latter also on vein 4 ; space between these 

 lines somewhat darker than rest of wing, more dusted with grey ; marginal area 

 decidedly ])aler; with slight traces of a submarginal line; marginal ilark dashes 

 between the veins; fringe pale; cell-spot black. 



Hindwings: similar. 



Underside altogether jialer, the forewing, especially towards base, dusted with 

 dark scales; all the lines thick and well marked; cell-sjiots distinct. Head, thorax, 

 and abdomen like wings: face dark brown. 



Expanse of wings : 22 mm.
