“ Both sexes of Acrea atolmis, Westw., were found by Dr. 
Longstaff to possess a faint odour, which, however, he does not 
describe. I did not examine the female, but a male specimen 
appeared to me to be scentless. 
“The smell of musty straw was very distinct in a female 
specimen of Acrea caldarena, Hew. It was only slightly 
apparent in a male examined by Dr. Longstaff. 
“In Acrea atergatis, Westw., [ found that the same musty 
odour was accompanied by a strong ammoniacal scent, like 
that of stable-litter. 
“Both sexes of Amauris echeria, Boisd. (form albimaculata, 
Butl.), yielded a similar smell of musty straw, accompanied in 
this case by an evanescent sharp or pungent scent like that of 
vinegar. A considerable amount of yellow juice, which seemed 
to be tasteless, was exuded by one male specimen. The 
characteristic smell adhered to the fingers after crushing a 
female specimen, though in this instance no fluid was seen. 
In regard to A. echeria, Mr. Marshall remarks that in the few 
specimens that he tried, no juice was emitted ; but they had a 
nauseous taste and a strong smell which reminded him some- 
what of that emitted by many Coccinellidx. Dr. Longstaff 
observed the musty smell and the transient pungent odour in 
both sexes ; the latter he compares to acetylene. One female 
was noted by him as possessing ‘a disagreeable odour like 
some animal.’ 
“The scent in both sexes of Limnas chrysippus, Linn., in- 
variably appeared to me to be of astrong and disagreeable 
nature, like that of cockroaches, often stronger in the female. 
The odour of the male seemed to contain an additional con- 
stituent, which I am inclined to compare to the perfume of 
burnt almonds. I found no increase of the scent when the 
glands of the hind-wing were crushed with the forceps. Dr. 
Longstaff noted a disagreeable odour in both sexes—stronger 
in the female—which he likens to that of musk-rats or cock- 
roaches. The excised glands of the male yielded on pressure 
a yellow or brown juice, without perceptible taste or odour.

Soc. Lond., 1905, pp. 87, 89,108,137.) That great individual 
differences exist in the appreciation of these scents appears
