saturated with grease, altogether destroying the original colouring, but it is identical, 

 as far as can be seen, with a specimen iu the British Museum (!ollection, unnamed, 

 from Aden, taken by Major Yerbury, and dated March 19, 189S, from which the 

 description, as far as regards the ground colour, is taken. The markings are 

 precisely similar, but the size of the Aden specimen is a little less. 



This species is named in honour of our assistant, Mr. A. W. Waters.

One ?, 13. iii. 1901. Gebel Margel, near Shendi. 



This moth was abundant on Gebel Margel. It rests by day, sitting like a 

 Boarmia on the rocks of the Gebel — rocks entirely destitute of vegetation, and 

 so hot that it is well-nigh impossible to touch them. The insect is exceedingly 

 skittish, and, owing to the slippery nature of the ground, very difficult to catch. 

 We failed to attract it with light.
