a very different climate with a regular wet and dry season, 

 as Miss Britten ascertained from the meteorological records, 

 and as Mr. Neave observed on the spot. Although oetavia 

 appears to be always wet in equatorial Uganda and perhaps 

 in the extreme W. of B.E.A., this is by no means true of 

 B.E.A. as a whole, for many records testify to the existence 

 of dry forms (Trans. Ent. Soc. 3 1902, p. 447; 1908, pp. 

 542-44). 



Precis antilope did not appear in the collection studied by 

 Mr. Neave, but both dry and wet forms occur in equatorial 

 B.E.A. (St. Aubyn Rogers, Trans. Ent. Soc, 1908, pp. 544-45). 



Looking at the above tables it is seen that Precis octama 

 and P. actio, follow the dry and wet seasons with precision 

 except for the presence of 2 wet forms of octavia in the first 

 dry period, and these, being worn, had probably lived for a 

 considerable time. The record of artaxia is very similar. 

 P. antilope, on the other hand, shows a strong tendency to 

 anticipate the seasons, both wet and dry, as is seen in the 

 group of wet forms taken Jan. 8-Mar. 21. 1917, and the dry 

 between Apr. 1 and July 25 of the same year, the latter 

 being mixed with wet forms towards the end of the wet 

 season. P. archesia follows the seasons except for a single 

 early wet form on Nov. 19, 1917. 



" Satyrinae. — There is a species here on the kopje and 

 elsewhere that is new to me — a pretty fawn-coloured large 

 species [Henotesia simonsi, But!.]. There are others (Yphthima, 

 etc.) here which are probably different from those I have sent 

 before. 



' Lycaenidae. — There are very few on the kopje, but when 

 here for a week in August I got a fine species new to me, 

 which vim have received previously to this letter— one of 

 those with the spots on the underside split. The male is of 

 a coppery brown colour [Deudorix dinochares, H. Gr.-Sm.]. 

 However, there are, I think, two other species here new to 

 me which I send now. One of them has a very boldly marked 

 underside [Spindasis homeyeri, Dew.]: it has its tails ab- 

 stracted by some enemy. The other is one of those rich 

 copper-coloured forms with red brown underside and very 

 short twisted tails. [Both Axion-rscs hmpux. V .. and amanga,
