common origin, while in Eumcnia it is oblique, and only 

 meets the 1st median some way from its origin. 



The plain ochreous colouring of the type of Deloneura 

 is strikingly different from the rich dark hues of Eu- 

 tne^iia. 



Deloneura immaculata, (PL V. fig. 4). 



Exp. 1 in. 5 lin. — 1 in. 9 lin. 



Yellow- ochreous, without spot or marhing of any descrip- 

 tion. 



Underside. — Hind- wing, and costal and hind-mai-ginal 

 region of fore-wing slightly paler. 



Thorax, head, palpi, antennoe, and legs dull-hlacl: j the 

 antennae tipped, and the back of thorax scaled with 

 ochreous; abdomen ochreous beneath, ochreous mixed 

 with blackish above. 



Hab. Bashee River, Kaffraria. 



Entomology is indebted to Mr. J. H. Bowker for the 

 discovery of this remarkable butterfly, which took place 

 at the end of December, 1863. In some letters addressed 

 to me about that time, Mr. Bowker notes the species as 

 " a true forest insect, only found in or at the edge of 

 woods, and appearing but for a few days. In flight they 

 resemble Acrma Horta, and still more the yelloiu tree- 

 moth,'^ whirling slowly, with flapping wings, round the 

 tops of trees, rising and falling, sailing away and return- 

 ing.^' t The species would seem to be extremely local, 

 Mr. Bowker not having met with it elsewhere than on 

 the Bashee River, though constantly collecting in many 

 other parts of Kaffraria in which he has been stationed.

* Mr. Bowker here alludes, I believe, to a species of Aroa (a genus of 

 Liparideous Bombycina allied to Orgyia] wliich abounds in the wooded 

 regions of South Africa, — A. crocata, Walker. 



f Mr. Salvin informs me that he has observed Eumenice on the wing in 

 Central America, and that their flight, with the exception of being lower, 

 is not unlike that here described.
