same publication Vol. v. (1912) pp. 93-113. ‘The present paper 
deals with the collections of the years 1912-1914 and 1917-1919. 
The writer had the pleasurable anticipation of the co-operation 
of Mr R. A. Rolfe in the elucidation of the present series but to 
the great regret of all who knew him Mr Rolfe died on 13th 
April 1921. All that was accomplished together was two days’ 
survey of the series, employed in comparison of the specimens 
with the types at Kew. ‘This served to eliminate the majority 
of- the known species which was all that could be done at the 
time? Consequently for any érrors in identification or descrip- 
tion in what follows the present writer is responsible.
