no attempt was made to determine the position of urania, 

 both groups being arranged under posthumus. 



In the British Museum, examples of Group 1 (posthumus) 

 arc included from Sierra Leone, Cape Coast Castle, Gold 

 Coast, Ashanti, Kumasi, Accra, Calabar, Old Calabar; examples 

 of Group 2 (urania) from Sierra Leone, Old Calabar, Cameroon, 

 and W. Uganda. In the Hope Department, 4 males from 

 Oni, 70 miles E. of Lagos (W. A. Lamborn), and 1 from Old 

 Calabar are posthumus; 1 male labelled " trop. Africa" is 

 urania. 



Both species occur together on the West Coast, but post- 

 humus predominates to the N. and urania to the S. So far 

 as at present known urania is the only species in W. Uganda, 

 this locality being represented by one male and three females 

 collected by Mr. Neave. Of these, the male (M'panga Forest, 

 Toro) exhibits an increase in the black parts of the upper 

 surface pattern as compared with W. Coast specimens, while 

 all three females (Buamba Forest, Semliki Valley) possess the 

 above-mentioned series of blue spots on the fore-wing upper 

 surface. 



It has not been deemed necessary to repeat the full refer-

The habits of Ethiopian species of Sarangesa and 



OTHER HeSPERIDAE. Prof. POULTON lead extracts on the 

 above subject from a letter written by the Rev. K. St. Aubyn 

 Rogers from Kongwa, in ex-German East Africa, near the 

 Central Railway and due W. of Zanzibar: — 



"Nor. 22, L917. 

 "' 1 have been intending to give you my experiences of the 

 habits of the genus Sarangesa for some time. They are cer- 

 tainly not exclusively nocturnal, as they fly and visit flowers 

 quite freely at all hours of the day at all seasons even up to 

 dusk. 1 rather fancy the peculiar habit of resting during the 

 day in dark places is characteristic, perhaps exclusively, of 

 places with a marked dry season and only in that season. 

 I remember at Taveta noticing S. eliminata, I loll., in numbers 

 down a well shaft, and here I have observed a more variegated
