Next comes tlie vexed question of scent-glands. I was so dis- 
couraged by the loss of all my notes on this and other structural matters 
in 1887, that I have taken hut few since, so I cannot now speak with 
much authority on the subject. 
It seems probable that there is a disagreeable odour in all Danaidce, 
apart from that of the anal tufts and alar glands. Though infinitely less 
in strength than it is in the Agaristidue and other moths, it is still quite 
perceptiblo on pinching soma species, such as Danais genutia, crocea and 
vulgaris (which smolls of sorrel). In others I cannot make it out at all. 
This smell is probably associated with a taste highly disagreeable to 
spiders, chickens, etc. The results of my experiments made some years 
ago in the Celebes, Java, etc., are now lost, but in the Malay Peninsula 
I lately made a few on spiders, with the following results. Except in 
the case of the first two species, they cannot be entirely trusted. 
Species always rejected, Danais genutia , 
Badena vxdgaris, 
Ornitlioptera ruficollis, 
(only two offered). 
Species sometimes rejected, Diipleea midamus ; 
„ rhadamanthus, 
Neptis varmona, 
Cethosia hypsina, 
Loxura atymnus, 
Lampides cslianus. 
Species never rejected, Neptis sp. 
Athyma sp. etc. 
It is to be observed that the Radenas are perhaps the most perfectly
