The production of the fulvous-marked mimetic female of a/tho/fi 
has involved a wider departure from the pattern of the male than 
that described in the paler mimetic females. The markings in the 
basal half of the fore wing of the former have not only been 
changed in tint, but they have also coalesced into a broad fulvous 
area interrupted only by the three black spots below the cell. 
A point of special interest is the development of one or two fulv- 
ous striæ in the black border at and above the anal angle, repres- 
enting the less peripherally placed stria that are very charac- 
teristic of the female jodutta. In the hind wing also, the depart- 
ure from the pattern of the male has been greater; for the fulvous 
area, representing the yellow band, is far more extended than the 
pale areas of the other females — both white and yellow. 
In concluding this account of the mimetic forms of A. althoffi 
I wish to call attention to the resemblance of the under surface of 
the male to that of the aurivillii female of A. alciope. There is 
considerable likeness, in colour as well as in pattern, between the 
parts exposed in the resting position. If this suggested resemblance 
be confirmed by observations in the field, the males of althoffi 
should be given a place in Table I, and, being mimics of a mimic, 
would provide additional evidence that the likeness of the female 
alciope to the Planemas of Combination I is Múllerian. On the 
upper surface, too, the pattern of the male althofi suggests an 
outlying association with Combination I, and the white patch on 
the hind wing of Acrwa admatha leucographa RIBBE may have 
become the characteristic of the Uganda form under the influence 
of the same Combination. There also appears to be a likeness which 
may be significant between the under surface of the male of A. 
althoffi and that of A. pelasgius GROSE-SMITH.

The beautiful mimetic Pseudacrea, the female of Ps. hobleyz, 
has been already considered on page 406. Itis here only necessary to 
speak of its relative abundance, 28 specimens having been taken, 
as compared with 39 and 11 of the two models respectively. 
Accepting Dr. JORDAN's conclusions, we find the following
