group II, and A. zetes, Liun., the first species in sub-group 

 IV. I consider that, notwithstanding the extreme attenua- 

 tion of the upper side hind-marginal border of the hind-wing, 

 the disposition of the spots throughout, and also the broad 

 unspotted fulvous discal-submarginal band of the hind-wing 

 under side — though this feature is developed with excep- 

 tional prominence, — bring this form into much closer 

 approximation to A. stenohcea, Wallengr., and in a less 

 degree to A. aglaonice, Westw., and A. calclarena, Hewits. 



The new sub-species rubcsccns here described inhabits 

 British East Africa, and the 6 $ and 1 ^ in the Hope 

 Department of the Oxford University Museum, all bear 

 the following data, viz. " About 6000 ft., 15 m. W. of Ft. 

 Hall, Kikuyu Co., Weithaga, capt. and pres. 1907, by 

 K. St. A. Rogers." The tickets further note the dates of 

 capture, vid.: of the 6 $, Aug. 15, 1906, Feb. 15th and 

 22nd, and March 12th, 15th and 25th, and of the $, March 

 loth, 1907. 



Type of male captured March 12, 1907, of female 

 captured March 15tli, 1907, both from Weithaga, in the 

 Hope Department, Oxford University Museum. 



Specimens of typical asholoplintha in the same Museum 

 bear records of capture in the Tiriki Hills, 20 m. N. of 

 Kisumu (C. A. Wiggins) and on W. shore of Victoria 

 Nyanza, 60 m. along Anglo-German boundar}'^, (1^ S. Lat.) 

 (Captain T. T. Behrens, R.E.), all dated as taken in March 

 1903 ; and others, in my collection, were captured by Mr. 

 C. W. Hobley at Kaimosi and Nandi on different days 

 during February and March, 1903.
