 flight — alternately flapping its wings and skimming along in its 

 flight, very differently to other Acrceince." (B. G.)

" Dark yellow oblong ova." (B. G.) 



This appears to be a second female form of A. stenobea, of which 

 A. ligus seems to be the more typical female ; excepting in the 

 narrow border to the primaries, this new form much resembles 

 the commoner female of A. caldarena, but the arrangement of the 

 spots is as in A. stenobea.

d , Nairobi plains, 5400 feet, March 29, 1900. 

 " Common round my tent on the plains." (B. G.) 

 Females of this species (no. 440) are much needed for the 

 Museum collection ; of A. pudorina we possess only one of the 

 dark variety of female, and of typical A. acrita the same ; we have 

 several females of A. pudorina resembling the male in colouring, 

 but they are not in good condition.

" I have achieved the capture of this remarkable insect after 

 having seen some three or four during the past ten days without 

 being able to get on level terms with one of them. This Acrcea 

 frequents primaeval forest : rather unusual for members of the 

 genus, I shoidd think."
