at present the fact is not proved." Mr. Loafs collection 

 appears to me to bring positive evidence against tbe view 

 of their identity, and from the above considerations I think 

 there can be little doubt that Mr. G. A. K. Marshall is 

 right in entirely dissociating T. cvagorc in all its forms 

 (including T. noana, Luc.) from T. yerhurii (i.e. T. daira). 



I am indebted to Professor Poulton, F.R.S., for the 

 opportunity of working out Mr. Loafs interesting col- 

 lection, and also for the Plate which accompanies this 

 paper.

The iiicl-sea^on $ (I'^ig- 2) is less brightly coloured than the 



corresponding ^ (Fig- 1). 

 In the dry seusuii both sexes adopt cryptic colouring on 

 the luider-side, accompanied l>y leaf-like shaping of the 

 fore- and hind-wing, more pronounced in the $ (Fig. 4) 

 than in the ^ (Fig. 3).

The icd-si^umn $ (Fig. 6) retains some of the colouring of 



the dry-season form. 

 Both sexes in the dry season (Figs. 7 and 8) show slight 



nncination of the lore- wing. 

 The specimens represented in Figs, 6 and 8 were bred by 

 Mr. Mansel Weale, and belong to the series referred to in 

 Trans. Ent. Soc, Lond., 1902, p. 201.
