The Hind-tving Under Surface. — Ethiopica is, on the 

 average, of a darker reddish colour than pseudophlaeas and 

 has darker and more pronounced dusky internervular mark- 

 ings just inside the marginal red band. The more basal dark 

 spots vary greatly in both races, being sometimes distinct, 

 sometimes evanescent in both. In the tint of the under surface 

 abhoti appears to be somewhat nearer to pseudophlaeas. 



The fine central line of a deeper red which traverses the 

 marginal band and is composed of a curved section, out- 

 wardly concave, in each space, is far moje distinct in most 

 examples of ethiopica than in any of pseudophlaeas, in which 

 indeed it is generally very indistinct. The band itself is 

 also less strongly marked in pseudophlaeas — especially so in 

 the two Paris males — thus giving to the under surface a more 

 uniform appearance than that of ethiopica. 



The Under Surface of the Abdomen. — This surface varies 

 greatly in tint, but it is, on the average, paler in pseudophlaeas, 

 and, in a larger proportion of individuals, white, than in 

 ethiopica. 



Comparison between the Northern and Southern ethiopica. — 

 The differences were extremely slight and only recognisable 

 by the study and comparison of the whole series from each 

 area. On the average the red marginal band of the hind- 

 wing was slightly broader in the south, and, on the under 

 surface, the fine central deep red line traversing this band 

 was brighter and more sharply defined. The under surface 

 as a whole was very similar but slightly brighter in the south. 

 There was no perceptible difference in the shade of red in 

 the fore-wing or in the basal iridescence, sometimes spreading 

 over the whole of the black area, in the hind. 



PSEUDOPONTIA PARADOXA FeLD. ; ITS BIONOMICS, GEO- 

 GRAPHICAL RACES, AND AFFINITY. — Prof. POULTON Said that 



he had recently received a collection of Lepidoptera made in 

 July 1921 in the Semliki Valley by his friends Mr. C. A. 

 Wiggins, P.M.O. Uganda Prot., and Dr. G. D. H. Carpenter, 

 D.M. The precise locality was the Buamba Forest in that 

 part of the Semliki Valley which lies west of the north end 

 of Ruwenzori and in British territory, viz. Toro, Uganda, 

 The elevation was about 3000 ft. and the position about
