14 ME. GUT A, K. MARSH-iLL ON THE [Jan. 19, 



Founded ou three males and one female (wet-season specimens) 

 caught on January 5, 1 894, at Parumbira in German East Africa, 

 by Dr. Ansorge, to w hom I have dedicated the species. 



22. Teracolus aurigineus. 



Teracolus aurigineus, Butler, Ann. Mag. N. H. (5) xii, p. 103 

 (1883). 



Teracolus venusius, Butler, Proc. Zool. Soc. p. 94 (1888). 



This species occurs in Equatorial East Africa, being recorded from 

 Wadelai southward to Lake Xyasa, appearing to be common 

 wherever it occurs. T. venustus, Butl., from Kilimanjaro, is the 

 dry-season form, being smaller and having the underside of a more 

 pinkish tinge, but the colouring above is unchanged. 



23. Teracolus doubledati. 



Idmais doubledayi, Hoppfer, Peters, Eeise Mossamb. p. 362 

 (1862). 



Idmais chrysonome, Doubleday {nee Klug), Gen. D. Lep. pi. vii. 

 fig. 5 (1847). 



Idmais vesta, Trimen {nee Eeiche), Ebop. Afr. Aiist. p. 62 

 (1862). 



Idmais hewitsoni, Kirby, 8yn. Cat. Lep. p. 498 (1871). 



This is the West- African representative of T. vesta, Eeiche. The 

 specimens in the British Museum are from Angola and the Congo. 



24. Teracolus chrysonome. 



Poniia chrifsonome, Klug, Symb. Phys., Ins. pi. vii. figs. 9-11 

 (1829). 



Teracolus helvolus, Butler, Proc. Zool. Soc. p. 94 (1888). 



T. chnfsononiehas not been recorded south of Kilimanjaro, occur- 

 ring northward as far as Dougola and Somaliland. The smaller 

 T. helvolus with its pinkish underside colouring represents the dry- 

 season brood. 



25. Teracolus gaudej«-s. 



Teracolus gaudens, Butler, Ann. Mag. N. H. (4) xviii. p. 486 

 (1876). 



Teracolus arenicolens, Butler, Ent. Mo. Mag. p. 81 (1884). 



Founded on a single male from Abyssinia. It differs from 

 T. clrnjscnome in the reduction of the black discal ray in fore wing 

 and its larger basal grey patch. A long series, however, would 

 probably show them to be inseparable. T. arenicolens, founded 

 on a single specimen from Arabia, is clearly the dry-season form. 



26. Teracolus pleione. 



Pontia 2)leione, Klug, Symb. Phys., Ins. pi. viii. figs. 7 & 8 (1829). 

 Idmais miriam, Felder, Eeise iso\., Lep. p. 190, pi. xxvii. figs. 3 

 & 4 (1865). 



Ttracolus cJirysomela, Butler, Cist. Ent. p. 244 (1874).
