THYRIDIDAE OF AFRICA AND ITS ISLANDS 87 



The similarities between the Indian and African species are so striking that a close 

 common ancestry seems likely, there are too many similar characters to suggest a 

 convergent relationship. The two species are, however, sufficiently distinct to be 

 regarded as species rather than subspecies. Unfortunately no information is 

 available on the food plants of either species.

Material examined. 



Holotype $, Ghana: Aburi, ix.1872, not traced. This specimen is not in Berlin 

 (Hannemanni, in litt.) nor in Griefswald (Groth, in litt.). Both these places have 

 some Plotz types. There is no doubt of the identity of the species described by 

 Plotz, hence no neotype is designated.
