intersegmental bands and long branched spines, a species of 
Automeris, he noticed that some of the black bands appeared 
to be swollen. To his amazement these swellings, when 
touched, quickly slid over the back of the caterpillar to the 
other side with the hurried motion of a Pyralid larva, and 
indeed turned out to be small lepidopterous larvae as black 
and glossy as the bands of the Automeris caterpillar. Mr. Moss 
found it very difficult to catch these larvae with the forceps 
on account of the swiftness with which they rushed from one 
side of the host to the other. They are well protected by their 
colour as well as the long spines of the Automeris. It is to 
be hoped that Mr. Moss will succeed in obtaining more explicit 
information about this curious larva and in breeding the moth. 
Instructions for exhibiting specimens in the Epidiascope. 
The Rev. G. WHEELER explained to Fellows that the 
Epidiascope, by means of which the last two exhibits had 
been made, would not throw on to the screen anything of 
greater size than an ellipse of 11 ins. by 8 ins., and further, 
that, in consequence of the construction of the instrument, 
any specimens exhibited in a box of larger dimensions must 
be placed at the right-hand side of the box. It is also neces- 
sary to remember that the edges of a box throw a shadow, 
and that it is therefore important that specimens for exhibition 
should not be placed too close to the edge.
