2i8 SOUTH-AFRICAN BUTTERFLIES. 



base to baud I'atlier widely speckled with white ; inner discal area 

 smooth fuscous, not speckled; in discoidal cell two blackish white- 

 ringed spots, one near base rounded, the other 8-shaped about 

 middle ; a similar larger, curved, sublunulate mark at extremity of 

 cell. Hind-ioing : a double parallel series of white annulets near base, 

 — two annulets being above discoidal cell, two 8-shaped ones in 

 cell, and two below cell ; an imperfect elongate suffused white lunule 

 at extremity of cell ; a series of nine elongate, orange, outirardhj black 

 and brown dotted, white-ringed spots, suhnarginal for the greater part 

 of its course, rou7id the wing from costcc beyond middle to inner margin 

 close to base. Cilia brownish, with very small white inter-nervular 

 interruptions. 



$ Similar, slightly ixdcr. Fore-icing : baud broader, its upper 

 three spots confluent ; a very small additional (sixth) spot between 

 first median nervule and submedian nervure. Hind-wing : baud broader, 

 except as regards the first spot. Under side. — As in ^, but subocellate 

 orange and blackish white-ringed spots in the hind-wing enlarged and 

 slightly suffused. 



The p)osition of the orange band on the upper side of both wings at 

 once distinguishes this very handsome form from D. Amahosa, as in 

 none of those of the latter in which the orange is most developed does 

 its external edge come nearly so close to the hind-margin ; tlie brighter, 

 redder tint of the orange is also very noticeable in Limbata, as well 

 as the more important distinction that, in both sexes, tlic band of 

 the fore-wings is broader in its upper than in its lower iiortion (the 

 reverse being the case in AmaJcosa) ; in the ^, also the sixth (lowest) 

 spot in the fore-wing band is absent, and in the ^ it is very small. 

 On the under side, the browner less ashy tint of the hind-wing and 

 border of fore-wing, with the distinct black cellular markings and 

 inner edging of orange band, and in the hind-wing the very distinct 

 basal annulets and the long and conspicuous series (following three- 

 fourths of the circuit of the wing) of white-ringed red-and-blackish 

 spots — only a portion of which are indistinctly represented in some 

 specimens of Amalcosa, are also noticeable distinctions. There is much 

 less white in the cilia of D. limbata. 



The discovery of this butterfly is due to Mr. J. INI. Hutchinson of Kini- 

 bolton, near Estcourt, Natal, who sent me a $ in June 1882. I thought it 

 possible that this might be merely a sport of the variable D. Amalwsa, but 

 recommended JNIr. Hutchinson to look out for otlier specimens ; and in July 

 1884 I Avas delighted to receive from him two more ^ s and a $, with the 

 information that seven had been captured, including the paired sexes, about 

 three miles from Estcourt, and that these examples did not present any varia- 

 tion, particularly in the important feature of the position of the orange 

 bands. 



Mr. Hutchinson writes that the insect occurs in several spots along the 

 Bushman's River, but always in the same kind of station, viz., the sides or 

 summits of rocky hills. The specimens noticed were all — with one exception, 

 which was on the wing — sitting on stones, and were easily boxed while settled.
