W. L. Distant, Professor Meldola states :— 
‘“There is not the least warrant for the supposition that 
scent-glands or tufts have anything to do with distastefulness. 
The acrid juices of distasteful butterflies are not generally 
emitted from any particular organ, but permeate all the 
tissues of the body. The fact that such organs exist in one sex 
only is strongly suggestive, if not demonstrative, of the view 
that they are secondary sexual characters ; and as such they 
are regarded by Dr. Fritz Miller, who has systematically 
investigated these structures, and has in many cases actually 
detected the odour emitted, which is often of a pleasant 
character.” (Jen, Zeit., vol, xi, p. 99; Trans, Ent. Soc. Lond, 
1878, p. 211.) 
REMARKABLE Larva oF SpriRAmiopsis,—Professor E. B. 
Povtton also exhibited on behalf of Mr, G. F. Leigh, F.E.S., 
of Durban, a blown specimen of the larva of Spiramiopsis 
comma, Hampson, showing the two pairs of remarkable 
processes as well as the two eye-like spots, one situated in 
front of the base of each posterior process. The anterior 
pair are placed on the second thoracic segment, the posterior 
on the third. In the dried specimen the ground-colour of 
the dorsal and dorso-lateral regions of each of these segments 
is of a brilliant orange-brown tint, making a most effective 
background for the intensely black, nearly circular eye-like 
spots. The effect of these latter is also greatly enhanced 
by a dark semi-circular line placed outside a margin of orange 
embracing nearly half the circumference of each spot. This 
line, which is concentric with the eye-spot, bounds it upon . 
the posterior-inferior section of its cireumference. A sketch 
sent by Mr. Leigh in further explanation of his exhibit shows 
that, when touched, the larva curves the anterior segments 
so as to conceal its real head and make the central point 
between the eye-spots anterior in position. From this central 
point the four relatively immense processes radiate like spokes, 
while the bright orange colour and jet-black eye-spots placed 
on each side of the centre must contribute with them to 
produce an extraordinary and terrifying appearance. By Mr. 
Leigh’s desire the specimen will be placed beside the imagines
