Forrirings : ochrcous with a rufous tinge, spocldeil with darker, tlie speckles

1 c? from Second Kedong, British East Africa, February 1899 (Dr. Ansorge). 



Sui)erficially this insect resembles Microgonia mundata Gnen. from America. 



34. Aeschropteryx ansorgei ab. subrufa nov., and diflPusa nov. 

 This species proves to be very variable ; of 4 $ S from Ran, Naudi 

 Country, all differ from the type form. One, ab. subrufa, which agrees with it in 

 having the outer oblique line fine and thin, instead of having the ground colonr 

 pale yellow, is pale ochreous with a rufous flush throughout ; the others, ab. dijfusa, 

 on the contrary, agree with the type form in ground colour, but have the line thick, 

 chestnnt-brown, with a diffuse shade on either side but thickest externally, the 

 subajiical spot being likewise filled up with brown ; in the forewings a rufous cloud 

 runs from anal angle to the oblique Hue at its middle, and in the hindwing the 

 rufous tint takes the form of a zigzag submarginal shade, with a cloud beyond it. 

 In one of these three, moreover, the obliijue line itself, instead of running straight 

 throughout, is bent round at vein 2. All four specimens were taken February 23rd 

 and 24th, 1S99, by Dr. Ansorge.
