Dalaca ammon Wall. 
Mr Janse was kind enough to submit to my inspection about fifty specimens 
from a wide range of localities in Transvaal and Rhodesia representing forms i 
of this species, which he found himself unable satisfactorily to discriminate. | 
After careful study of the considerable variation shown in this series, and 
comparison of the types in the British Museum, I have been obliged to con- 
clude that fuscescens Hamps., rhodesiensis Hamps., and goniophora Hamps. 
are only synonyms of ammon, which I identify from Wallengren’s description. 
Dalaca exul H.S. 1 
Accepting lihvatus Walk, as a synonym of this species (as quoted in Junk’s 1 
Lepidopterovum Catalogus, which is probably correct), then I find that metaleuca f 
Hamps. and tumidifascia Hamps. are also synonyms of the same species. j 
Dalaca rufescens Hamps. 
I am of opinion that fuvva Hamps. is only a uniformly coloured variety of 
this. 
Dalaca ibex Wall. 
I consider alhirivula Hamps. is a variety of this. 
Dalaca antarctica Wall. 
This is referable here and not to Hepialns. |
