frequent and brilliant sunshine, and exquisitely clear and pure blue 

 sky, afford a striking contrast to that of the Metropolitan and manu-

NOTES ON RHOPALOCERA FEOM ANGOLA, WITH DESCEIPTION 

 OF A NEW SPECIES OF DEUDORIX FROM ZANZIBAR. 



BY W. C. HEWITSON, F.L.S. 



Mr. and Mrs. Monteiro, who have gone out to Delagoa Bay to 

 collect specimens of Natural History, have sent home a large number 

 of butterflies in the finest possible condition, but, with few exceptions, 

 which I shall presently mention, the same species which yve have had 

 from the Cape ; the same too (most of them) which Mr. Rogers sent 

 me from the opposite coast as long as he remained on the banks of the 

 river Quanza. The collection contains specimens of Papilio Colonna, 

 and a fine series of the beautiful Acrcea Rahhaics of Ward, from 

 Zanzibar, Bhomaleosoma Neophron, which I have had from the Zambesi, 

 and a number of specimens of the rare EreMa Panda, notable for its 

 lovely under-side. These were nearly all taken in the winter months, 

 during which Mr. Monteiro says scarcely an insect was to be had in 

 Angola. He was told that the summer would begin in October, but 

 when he wrote to me (Nov. 5) he said : " It has been very windy, cold, 

 and raining for the last few days, and the summer has not yet set in." 

 Mr. Monteiro is delighted with the country, and is very sanguine that 

 he will be able in " a couple of months time to gladden our eyes with 

 some really fine things." He will do that if he sends us some more of 

 the Zanzibar species, and two or three beautiful things figured by 

 Hopffer, from Mozambique. 



The following description is that of a new Deudoris, the female 

 of which I have from Zanzibar : — 



Deudokix Dariates, sp. n. 



Upper-aide (Male). Anterior wing dark brown ; posterior wing with one tail 

 scarlet ; the base brown, the outer margin black, narrow, the lobe rufous, with the 

 centre black, irrorated with gold. 



Under-side grey ; anterior wing with a spot at the end of the cell, and a broad 

 transverse band beyond the middle grey-brown, bordered on both sides with white : 

 a sub-marginal series of brown spots bordered inwardly with white ; posterior wing 

 nearly wliite towards the outer margin, marked near the base by five scarlet spots 

 bordered with white, crossed at the end of the cell by a spot, and beyond the middle 

 by a series of grey spots, bordered on both sides with brown, and by a sub-marginal 

 brown band ; the lobe and caudal spot black, crowned with gold, the spot between 

 gold, all bordered above with yellow. 



Exp., ly*^ inch. 



Hab. : Delagoa Bay.
