A valuable set of 77 butterflies from Southern Spain (Alge- 

 ciras, Cordova, Granada, Malaga, Gibraltar) were captured 

 (1901) and presented by Col. J. W, Yerbury. The excellent 

 condition of the specimens and the full data accompanying 

 them render the gift most acceptable. The specimens of the 

 Pierine, Zegris enpJieuic, with full data, were specially wanted. 



Col. Yerbury also presented a pair of the Bombus-like fly, 

 Mallota fucifonnis, captured by him at Hyeres (i<S9(S), and 

 a pair of the wasp-like fly, Ccria ciunenoidcs, captured at 

 Matheran, Bombay (11^79), by Major C. G. Nurse: for the 

 Mimicry Series. 



Material of inestimable value from Rhodesia, illustrating 

 seasonable changes and their causes, mimicry, &c,, was pre- 

 sented by Guy A. K. Marshall, Esq., together with a fine 

 series of specimens for the General Collection. Unless other- 

 wise mentioned, the specimens were captured or bred at 

 Salisbury, Mashonaland, in 1901. 



Twenty-five specimens of the Pierine genus Terias include 

 the results of many experiments in which Mr. Marshall at- 

 tempted to reproduce the wet season form by placing the 

 larva and pupa or the puQa alone in a damp atmosphere. 

 The species experimented on were T. scnegalcnsis, T. regularise 

 and T. brigitta. The results have been recorded and discussed 

 by Mr. Marshall (Ann. and Mag. Nat. Hist., 1901, vol. ii, 

 p. 39(S), and byDr. Dixey (Trans. Ent. Soc. Lond., 1902, p. 1H9). 



Fifteen specimens of the two species of the Nymphaline 

 genus Byblia, B. ilithyia and B. acluloia, included 4 captured 

 females and offspring reared from eggs laid by each of them ; 

 thus demonstrating the parallel seasonal alternation in pattern 

 and colouring of the under side of the wings in both species. 

 The results of these investigations, which in certain cases 

 included the use of a damp atmosphere, have been recorded 

 and discussed in the papers already referred to by Mr. G. A. K. 

 Marshall and Dr. F. A. Dixey. 



Three specimens of the Nymphaline butterfly Precis 

 archesia had been subjected in the pupal state to a moist 

 atmosphere. The forms were nevertheless those which are 

 characteristic of the dry season, apparently indicating that
