the markings are completely white. The basal streak along 
the median being considerably suffused with black scaling. 
Hind wing normal doris with the blue scaling extending on

Type 2 in Coll. Schmassmann, 
This very rare form, which is parallel to HZ. doris methar- 
mina, ab. fascinator, from N.W. Venezuela, was given 
unsuspectingly by the late Mr. A, i. Gibbs with many 
other doris to Mr. Schmassmann shortly before he died. 
[ have named the aberration after the late Mr. A. E. 
Gibbs. ‘ 
Heliconius wallacei brevimaculuta, ab. halli. 
Fore wing like brevimaculata, with the short median band 
white in place of the usual yellow, broken by the extra dark 
scaling along vein 2, Hind wing like typical wadlucet. 
Hab. Lower Amazon, Serpa, March 1914 (A. Hall). 
Type 2? in Coll, Schmassmann. 
This form is close to clytia, but as brevimaculata is a 
geographical race on the lower Amazon it is necessary to 
describe and record the occurrence of an accompanying white 
form. 
I have named this aberration after Mr. A. Hall.
