Tur Lepidoptera which are catalogued and described in the following pages were collected by me during a tour of service of thirteen months’ duration at Sierra Leone, West Africa, in the years 1891-92. With few exceptions their habitat was the rocky peninsula of Sierra Leone, which has an area of some twenty square miles. It is very hilly, some of the hills rising to a height of from 3000 to 4000 feet. The immediately surrounding country is flat and swampy, and, so far as I had an oppor- tunity of judging, is poor in Lepidoptera. Owing probably to its elevation, Sierra Leone is very rich in representa- tives of the genus Charazes. In the limited time at my disposal I obtained eighteen species—nineteen, including Palla (Charaxes) varanes—with both sexes in fifteen of these. In consequence of my having lost the notes I made at the time on the natural habits of the insects collected, the observations which I am enabled to make must necessarily be brief, fragmentary, and quoted from memory. ‘They may be divided roughly into two classes: the first comprising those which have remained in aristocratic solitude, and are essentially sylvan in their habits; the second class, those which seem to prefer the vicinity of man and his habitations. Of this latter the more noticeable are the Zygzenide amongst A2 iv INTRODUCTION. the Heterocera, and D. chrysippus, various species of Myca- lesis and Precis, H. dedalus, H. misippus (female com- paratively rare), Terius sp., and P. demoleus, menestheus, phorcas, leonidas, and pylades. The more distinctly West- African genera (Pseudacrea, Euryphene, Euphedra, Aterica, Cymothoé, Epitola) and the Ethiopian ones (Lachnoptera, Salamis, Euxanthe, and Charazes) confine themselves to the woods and forests. The butterflies of the genus Aferica fly sedately along shaded paths and among the trees, keeping near to the ground and frequently settling. They are gregarious insects, and three or four are fond of resting together, when, but for the presence of the female opis, which is conspicuously banded with yellow, they would be difficult to distmguish. The Huphedre fly swiftly through the lower branches of the trees. A gleam of sunlight piercing the foliage lights them up for an instant and then they disappear, having settled either on the upper surface of a leaf or on the leaves covering the ground. The members of the genus Huryphene have similar habits to those of Aferica, but their flight is stronger. A variety of the female, which is larger and has the upper surface of its hind wings of a golden-green colour, has the figures “1881” very distinctly marked in black on the superior surface of the secondaries, “18” beg in one and “81” in the other discoidal cell. The manner of flight of the genus Epztola is similar to that of Jolaus. They keep flying round im small but gradually widening circles in open patches in forests, keepmg some thirty or more feet from the ground; they select the most sunlit side of a tree, on the leaves of which they frequently rest and bask in the sun. | A female of.-Papilio antimachus was brought to me in December 1891. It had been caught by hand, by a child, in a garden of a village a few miles from Freetown whilst INTRODUCTION. Vv settling on a flower. It was in perfect condition, but, to my surprise, was smaller than the male. ‘ 7 ~ > =a Ss ' » ‘ s a 7 4 ; Maen ; J ; sks . a . ‘ / be Ae ; ‘ - ¢ . DF rt ) ‘ 4 AY?
