where Mr. Neave records 42 pelasgis from N.E. corner of 

 Victoria Nyanza, Entebbe and Toro : also Trans. Ent. Soc, 

 1908, p. 546. Examples bred by the Rev. K. St. Aubyn 

 Rogers at Weithaga, B.E.A., were only slightly less " wet " 

 than the parent {ibid., pp. 545, 546). 



Precis artaxia, Hew. — The few examples of this species 

 afford an interesting contrast with archesia ; for although 

 both appeared as wet and dry forms in the areas traversed 

 by Capt. Carpenter, archesia is represented by wet forms in 

 the tropical belt to the north, whereas all the specimens of 

 artaxia collected by Major Wiggins in the above-mentioned 

 locality were small dry forms, of which 42 are recorded by 

 Mr. Neave from Ugaia on the N.E. shore of Victoria Nyanza 

 (ibid., pp. 348, 349). Dr. Marshall and the late Capt, F. C. 

 Selous also observed the predominance of the dry form in 

 certain parts of S.E. Rhodesia and Portuguese E. Africa, and 

 it is probably adaptively connected with forested areas (Trans. 

 Ent, Soc, 1902, pp. 423, 439-41). Although the number of 

 specimens is so small, both nachtigalli, Dew., and the more 

 extreme wet form nobilitata, Thur., were taken by Capt. 

 Carpenter. 



It is of interest to compare the remaining species of Precis 

 in the following table with Mr. Neave's records from the 

 equatorial north (I.e.). Capt. Carpenter's actia, Dist., exhibits 

 both dry forms, actia, and wet, /areata, Rothsch. and Jord., 

 while the 10 northern records are all oi fur cat a. Mr. Neave's 

 figures for octavia, Cr., also represented by dry and wet forms 

 in the following table, are unfortunately erroneous, probably 

 because the author had suddenly to leave England before the 

 proofs of his paper were corrected. Specimens recorded as 

 the dry form, sesamus, Trim., were examined and found to 

 be the wet form natalensis, Staud., by Miss Britten, who 

 has made a careful study of velaria in the Hope Department. 

 Furthermore, the large numbers of octavia, actia, and archesia 

 sent to me in more recent years from the neighbourhood of 

 Entebbe by Major Wiggins are all wet forms. Only in the 

 Tero Forest on the W. shore of the lake, near the old Anglo- 

 GeTman boundary, do the dry forms of octavia begin to 

 appear, and this locality, although so near to Entebbe, has
