The literature on British East African Heterocera is not 

 extensive, and a great part of it is contained in recent German 

 publications mainly dealing with their adjoining territory, and 

 to which I have not had access. But the district is remarkable 

 mainly for specially developed forms. The most interesting col- 

 lection under notice contains a large number of those — many of 

 which appear to be still undescribed, and also a number of known 

 forms which have not hitherto been recorded from British East 

 Africa. The majority of the latter are known through allied 

 forms from the West Coast districts, from which they present 

 striking variations in colour ; I have not been able to examine 

 the genitalia. 



Out of a total of 126 species which I have examined, 36 appear 

 to be still undescribed, which seems a large proportion, considering 

 that the country where the collection was made is now traversed 

 by the Uganda Railway, which must offer special facilities to col- 

 lectors, but this region has never yet been thoroughly worked out. 

 I believe Mr. Feather has a large number of Heterocera still to 

 be examined, and I hope to be able to give the result of my 

 enquiries into them in a future paper. Professor Poulton, of 

 the Hope Museum at Oxford, has the butterfly portion of the 

 collection, and I understand that he has discovered several new 

 species amongst the specimens. 



Great credit is due to Mr. Feather for the exactness with which
