" An insect quite new to me, taken sitting on a rock on the banks 

 of the stream." (R. C.) 



Best known as a West-African species and hitherto unrecorded,

Of the female, which was first taken, Mr. Crawshay writes : — 

 " I do not recognize this ' Copper ' as an insect known to me. 

 It was taken when I was out shooting, and I fear became very 

 much knocked about during a long day's tramp." Of the male he 

 says : — " Found on the path on its side almost dead after a shower 

 of rain." 



Although well known as a South African insect, these are the 

 first examples of it I have seen from British East Africa.

Of those taken at Kiu, Mr. Crawshay says : — " Newly emerged 

 these last two days." Of the later captures, which are more 

 heavily marked and therefore more typical, he says : — " Hardly did 

 I expect to find this species at such an altitude. Hitherto I have 

 not seen it this side of Kiu, where on the flowering Mimosa it 

 abounds."
