Female. — In tlie case of tlie solitary female in the collection, the under 

 side of the secondaries from the basal band of spots outwardly to tlie 

 margin is broadly suffused with fuscous. Whether this is a constant 

 teatiire of this sex, it is imjjossible to say without more material at 

 command. It has the appearance to the writer of being a case of 

 aberrant melanism rather than as the normal coloration, but until we 

 know more of the species it will not be safe to nmke any positive 

 affirmations. 



Expanse of wings: male, 27-3.5 mm.; female, 3(5 mm. 



There are seven males and one female of this very i)retty little species 

 in the National Museum collection.'

There are seven males and three females in the collection, and they 

 do not differ materially from specimens from the region of the Cape, 

 except that the females are more or less suffused with whitish upon the 

 upper surface of the disks of the secondaries. Collected at Taveta.

ACRiEA ABBOTTII, new species. 

 (Plate YII, fig. 1.) 



Allied in some particulars to A. cahira, Hopffer, but widely different. 



Male. — Upper side: Anterior wings pale ochreous, with the base, 

 the cell, excex^t a small triangular space at its lower edge near its 

 outer end, the costal margin, the apex, and the outer margin broadly 

 black. The ground color is disposed in the form of an oval subapical 

 spot and a broad discal baud parallel to the outer margin. The inner 

 margin of the black apical area is minutely excised just above the 

 origin of the second median nervule, and just below there is a round 

 black spot. The black of the basal part of the wing is extended in the 

 form of a narrow streak for a short distance between the median and the
