Trentepohlia fuscoapicalis is a small species of the sub- 
genus that is apparently closest to 7. curtipennis (Speis.), 
likewise from Cameroun. This latter species is rust-yellow 
with the abdominal segments narrowly ringed with brown ; 
the wings with a large brownish-yellow stigma and with the 
apex suffused with yellowish.
