h.w. band, but there does not seem to be a corresponding 

 variation in dryope, as one might expect. They both vary in 

 the angulation of the f.w., but the range of the forms is not 

 quite coincident, for apparently in Angola and the Congo 

 region the southern form of dryo'pe occurs in conjunction with 

 the western form of hiarhas. These are not insuperable diffi- 

 culties in the way of considering the two forms as con specific, 

 but they emphasise the necessity for proof by breeding before 

 any such view can be properly accepted. I sincerely hope 

 that Leigh will be able to carry ovit the expei'iment he 

 suggests." 



A little later Mr. Marshall again wrote on the same subject ; 

 " I was looking at the Eurytelae in the British Museum the day' 

 before I left, and I was interested to notice that the southern 

 form of dryope differs notably from hiarhas in the disposition 

 of the markings below the cell on under-side of f.w. But in 

 one of the western forms (alinda, I think it is,) these markings 

 are identical with those of the western hiarhas, and the h.w. 

 band is also very similar in width and position ; so that this 

 possibly represents the more primitive form of dryope." 



Heredity in the female forms of Hypolimnas misippus. 

 — Professor Poulton showed a series of forty-nine females and 

 seven males (being all that had been kept of this sex) of 

 Hypolimnas 7nisi2)ptis, bred by Rev. K. St. Aubyn Rogers, 

 M.A., F.E.S., from a female captured October 31st, 1908, at 

 Rabai, near Mombasa, British East Africa, where the inaria 

 form of female is no commoner than the type form. The 

 female parent was intermediate between the type and the 

 inaria form, but on the whole nearer the former : it bore 

 a very faint white patch on each hind-wing, thus slightly 

 tending towards the var. alcippoides. It was a very remark- 

 able fact that the whole of the female offspring were inaria, — 

 not a single type form, not a single intermediate. On the other 

 hand, twenty-one specimens possessed to a variable extent, and 

 on the whole very slightly, the alcippoides characteristic of a 

 white patch on the hind-wing. The dates of emergence of 

 the females (including a crippled inaria emerging Nov. 27th 

 and not retained) and the whole of the males were as follows,
