74 Mr. H. Eltringham's Monograph of the 



A. neohide, f. sokotrana. 



Specimens of A. neobule from Sokotra have been described 

 by Butler and by Dixey {I.e.). These differ from the normal 

 form principally in the increased amount of black scaling at 

 apex, little or no ochreous scaling in the same region, the ground- 

 colour a richer red, the black spots larger, and the dark 

 h.-w. border blacker and smoother in outline, its spots being 

 less distinct. This Sokotra form has been named neohide, 

 subspecies sokotrana by Prof. Rebel (I. c.) and in the absence 

 of similar examples from other regions such a distinction 

 would be quite justified. Examples however, taken by Neave 

 in N.E. Rhodesia, are not distinguishable from these Sokotra 

 forms. It is one of those cases in which a form or variety in 

 one locality becomes the dominant race in another. 

 A. neobule sets, subsp. 



Differs from the typical neobule in the following points. 

 Average size generally smaller, f.-w. much less transparent, 

 apical black more pronounced, a submarginal row of inter- 

 nervular orange ochreous spots joining the much-extended 

 reddish basal suffusion. H.-w. with marginal border much 

 indented inwardly. The 5 much nearer the (^ in colour, often 

 with a considerable black powdering along median and nervure 

 1 in f.-w. 



A. neobule arahica, subsp. 



Wings with the exception of transparent apical part of 

 f.-w. uniform orange ochreous. Spots as in neobule but 

 smaller. H.-w. marginal border formed of shallow black arches 

 on a black marginal line enclosing internervular spots of ground- 

 colour. 



The h.-w. beneath is powdered with chalky white scales 

 and the black spots at base are not confluent and therefore 

 do not enclose white spots as in the typical form. 



The 9 is slightly larger and duller in colour, and the 

 f.-w. transparent apical patch rather broader. 



This form is represented by a ^ and ^ from Wadi Bagren 

 near Makalla and by four ^ ^ from Wadi Dhawriiteii near 

 Ras Fartak taken in March 1899. Prof Rebel's description 

 is accompanied by five excellent text figures showing the 

 structure of the genitalia. These leave no doubt as to the 

 specific identity of the form with neobule. 



Acraea neohide is somewhat variable thouorh none of the 

 variations show sufficient constancy to enable the forms to 

 be separated into races other than those above indicated.
