Precis archesia f. arid. extr. loo. coryndoni form. nov. 



3 ?. Differ above on the forewing from f. arid, archesia Cram, and by the 

 almost complete absence of red, and the blue is much more sky blue, not purplish ; 

 the blue forms a broad marginal band with a central black line, not two broken 

 blue submarginal lines ; the whole postmedian band is blue, not merely above 

 vein 4. On the hindwings the median band is duller and less distinct, and the 

 terminal edge is quite straight, not strongly crenulate ; the fringe is blue, not 

 white. Below it is even more extreme and patternless than the form. arid. ampl. 

 siaudingeri Dew. 



Habitat. Various parts of Angola 13 33, 4 ?? (Coryndon). 



Precis omissa sp. nov. 



3- This species is allied to milonia Feld. and ranana Gr. Smith and is in 

 many collections named ranana in error. Differs above from milonia by the 

 forewing being more produced at the apex, and by the rufous band being more 

 angled basad, and stopping short at vein 6. The hindwing has a longer tail, 

 is more bowed out at termen and the fulvous rufous band is narrower. The 

 white dot in apical area of forewmg is absent. 



$. Is duller and has the fulvous band on hindwing almost white. 



Length of forewing : 3 30 mm., ? 33 mm. Expanse : 3 64 mm., $ 71 mm.
