The writer has seen a specimen of fulvulus, said by Hine to agree 
with the type of fulvofrater Walker. The original description of 
mutatus Walker makes its synonymy probable, although the type must 
be studied before a final decision can be made. Hine was unable to 
find the type in the British Museum and Smart has suggested that it 
may be in the Hope Museum at Cambridge.
