Compared with ione-imperator phlegyas seems to be a very 

 distinct form, but through difficilis Em. Sharpe and Bettoni Butler 

 the gap between phlegyas and imperator is so well filled out, 

 that I am unable to draw a true line of distinction between this 

 forms and think one had better regard them all as local races 

 of one species. Miss Sharpe gives beautiful figures of some 

 individuals of all this forms, but there are in the collections also 

 many other individuals, which do not exactly agree with any 

 one of her figures and which consequently not agree with the 

 scheme accepted by her and by Mr Butler. 



24. Teracolus eupompe Klug f. theopompe Feld. 5 dV, — 

 Renk, Grebelein, Kaka; February and March. 



var. hib. dedecora Feld. 4 dV, 19. — Renk, Grebelein; 

 Februar}^ and March. 



Theopompe and dedecora were taken flying together at Renk 

 and G-ebelein, quite as is also the case at Aden (cfr Butler An. 

 N. H. (6) 20, p. 497). The rosy tint on the underside of the 

 hind wings in dedecora is often very faint. 



25. Teracolus omphale God. var. hib. theogone Boisd. 1 c% 

 19. — Renk, Kaka; February. 



Both the specimens are small, the male measuring 33 mm. 

 and the female only 28 mm. between the apices of the fore wings. 



26. Teracolus daira Klug. 4 cTd% 4 9$. — Abba-Island, 

 Eenk, Kaka; February 12 — 27. 



It is very peculiar to find this form, which is coloured like 

 a summer form, flying in the middle of the dry season together 

 with highly developed dry-season forms of other species. I there- 

 fore do not think that T. nouna Lucas is really a dry-season 

 form of daira. 



27. Teracolus Heuglini Feld. 5 oV, 5 99. — Renk, Kaka; 

 February 20—28. 



The female is very variable; one of the specimens agrees 

 very nearly with the males, differing only by the great marginal 

 dots of the upper side of hind wing; in the males these dots 

 are very small, punctiform; three of the females have a more 

 or less distinct transverse black line near the innerside of the
