Show 1897.] BUTTERFLIES OF THE GENUS TERACOLUS. 17 was right in referring his specimen to T. eunoma, as the apical patch of the former is very variable, and two of the spots show a tendency to become obsolete ; also the discal row of spots on underside of hind wing, which is absent in typical T. eunoma, is partially obsolete in two specimens of the T. chromiferus form that I have seen. Beyond the Hewitson male and that described by Mr. Rothschild I only know of four others, which were caught by myself at Beira, East Africa, in January 1896. One of these males was taken in copula, and the following is the description of the female :- Upperside.-Yellowish white, with black spots and markings, without any coloured apical patch. Fore wing: Costa narrowly edged with fuscous. Terminal discocellular spot very large. Beyond middle a curved row of six large black spots, that on costa being larger than the rest. Black hind-marginal border fairly broad at apex, narrowing towards interior angle, radiating very broadly on nervules so as to give it a strongly^dentate appearance ; the radiations on third subcostal and upper radial nervules extended so as to just touch first and second spots of discal row. Base of wing very broadly clouded with fuscous, almost as in T. annce, Wallgr. Hind wing: Basal fuscous suffusion much fainter and more restricted than in fore wing. Hind-marginal nervular spots very large and diffuse, produced somewhat on nervules inwardly. Underside.-Fore wing: Apical patch pale yellowish. Discal row of spots as on upperside, but first spot divided into two discocellular spots as above; an ill-defined patch of fuscous clouding in the middle of the discoidal cell. Hind wing: As in male, but the ground-colour of a deeper, richer yellow, and the black spots of angulated discal row all strongly marked. In Miss Sharpe's collection I found another female which is clearly attributable to this species, but differs from the foregoing specimen in having the hind-marginal border suffused so as to enclose the four upper black spots of discal row, leaving three small white spots in the black apical patch. I have also seen three similar females collected by Dr. Ansorge in East Africa. I have not yet seen a dry-season specimen of this species. 35. TERACOLUS HETAERA. Ccdlosune hetcera, Gerstacker, Arch. f. Nat. xxxvii. p. 357 (1871). Teracolus puniceus, Butler, Proc. Zool. Soc. p. 72 (1888). Teracolus follaceus, Butler, ibid. p. 573, pl. xxxvi. fig. 7 (1894). This species in its summer garb is distinguished from T. eunoma by its much larger crimson-lake apical patch, and the distinct fine black neuration on the upperside of both wings, the hind wings in T. eunoma having none at all. Moreover the underside of hind wing is only faintly tinged with yellowish, and bears a discal ray from costa similar to that in T. jalone, Butl.; whereas the same part in T. eunoma is always of a bright yellow colour, and presents an angulated discal row of spots exactly like that in the wet-season P R O O .
