NOTES ON THE LEPIDOPTERA OF NATAL. 7 



like Candiope, is a bush lover ; and so is Citliceron generally, 

 although specially affecting orange groves. Jahliisa, with its 

 silver- spotted under side, is not found freely coastwards, but in 

 kloofs and bushes up-country. Zoolina and Neanthes, which, 

 except for the fact that Zoolina is white and Neanthes ochreous, 

 are identical in markings, habits, and sexual differences, and 

 appear to be a variety of one another, are coast butterflies, 

 haunting low mimosa trees in glades, or waste scrub, or rows of 

 " bois noir," a mimosa that has been introduced into Natal, and 

 is often planted on sugar estates as a margin to roads. 



The metamorphoses of these insects are not at all well known. 

 I reared Cith(Bron and Brutus from the larvse, but did not obtain 

 any others. The larvee in these cases were somewhat slug-formed, 

 with very pronounced heads, green with a rough skin, and with 

 delicate blue markings and edgings. They differed sexually in 

 both instances, and the head had four or more short irregular 

 processes or horns, edged and tipped with colour. Of Brutus I 

 only bred a few, but of Cith(Bron many. The sexual difference of 

 the latter was that the females had a large dorsal sub -cordate 

 cream mark which was wanting, or only shown by a dot, in the 

 males, and the colour was more vivid in the edgings to the frontal 

 horns. Brutus had pale, oblique, lateral lines, in the reverse 

 direction to those on the sphingiform caterpillars. 



The next genus, Pseudacrcea, has already been referred to 

 several times ; it is a small famil}^, consisting of only P. Tarquinia 

 and P. BoisduvaUi. I believe another, P. imitator, is added in 

 Mr. Trimen's list, but I have not seen it, and am inclined to think 

 that as P. BoisduvaUi is imitative in both its sexual forms of Acraa 

 Acara, so the two forms, P. Tarquinia and imitator, are imita- 

 tive of sexual differences of Acrcea Aganice, and are sexual vars. 

 of the same insect. It lives apparently on sufferance by its 

 imitative powers of the odious Acrceidce. When present on the 

 wing, I have always found it in company with its patron. I am 

 unaware of its transformations, but should not be surprised to find 

 the larval state also an imitative one of the Acrcea family.
