Dr. Longstaff, who found the scent faint (as [ did in some 
instances), characterizes it as ‘clean, flowery’ ; and compares 
it with that of Ganoris brassice, Linn. 
“ Teracolus exis, Klug, was only encountered in small 
numbers. A male caught by me on the banks of the Zambesi 
had a distinct flowery scent when fresh. A corresponding 
observation was made by Dr. Longstaff. 
“In Teracolus omphale, Godt., ¢, 1 was invariably able to 
detect an odour, always well-marked and often strong. This 
odour in the first place resembled that of 7’. auxo in its 
likeness to the fragrance of Philadelphus ; a possibly nearer 
comparison, however, being with the white lily. But in 
addition to this ‘ white-flower perfume’ there was nearly 
always present an aromatic, almost ‘snuffy’ constituent of 
different character, hard to define; this gave to the scent a 
certain roughness—not, as in G. rapx, the roughness of 
sweetbriar—and suggested at one time chocolate, at another 
musk, while itself quite distinct from either. Two females of 
this species were found to be completely devoid of odour. 
Dr. Longstafi’s results with 7. omphale 3 were largely nega- 
tive. In three specimens, however, he found a fairly strong 
scent which he compares to that of /eesia or honeysuckle. 
“The scent in Zeracolus ione, Godt., ¢, cannot always be 
detected. When present, it is sweet, flowery, and apparently 
free from all traces of ‘ snuffiness.’ 
“ Eronia cleodora, Hiibn., ¢. In this form the intensity of 
the odour varies greatly; the scent is sometimes absent 
altogether, but when present may be strong. Its basis is a 
flowery perfume like that found in many species of Teracolus, 
but to this is superadded an aromatic element giving a distinct 
suggestion of sweet chocolate. Dr. Longstaff, who found the 
scent very faint in all his specimens, considers it to belong to 
the G. brassicx type. 
“ Belenois gidica, Godt., ¢, appears in many instances to be 
without perceptible odour. Occasionally, however, I found it 
to possess an odour of roses, which in one of my specimens was 
strong. Dr. Longstaff’s results were mainly negative, but in 
a few instances he reports a slight, sweet flowery perfume. 
“ A specimen of Belenois mesentina, Cram., d, emitted, when
