are held erect, and the greatly lengthened legs of the second and third seg- 
ments held outstretched; thus, when seen from the front, the whole aspect 
of the insect, both in form and colour, is most spider-like, and when alarmed 
it immediately raises its four long legs and moves them irregularly, after 
the manner ofa spider attacking its victim. This spider-like appearance is 
believed to be a special protection against ichneumons which may approach 
it from the front. According to the experience of H. Miiller ichnueumons 
are especially afraid of spiders, and he states, on the authority of Fledder- 
mann, an experienced breeder of insects, that the larva of S. Fagi was never 
found to be attacked by ichneumons, whilst, according to Treitschke, the 
nearly allied Hypocampa Milhauseri is often attacked by them, although 
a much rarer species, which rarity may perhaps be attributable to the 
complete absence of such protection as that possessed by Stawropus Fagi. 
When approached from the rear there is nothing to be seen but the erect, 
hard, shield-like surface of the last segment surmounted by two black 
horns, and presenting an appearance totally unlike that of a caterpillar, 
When a side-view of the larva is presented there is seen on the fourth and 
fifth segments a small black depression just below the spiracles, and giving 
the appearance of a caterpillar which has already been stung by an ichneumon, 
so that one of these foes approaching from the side would be deceived and 
abandon it without depositing its eggs.” 
Mr. S. Stevens stated that, having recently reared several specimens of 
S. Fagi, he could confirm the opinion of Dr. H. Miller as to the spider- 
like appearance of the larva. 
The Rev. H. S. Gorham communicated a continuation of his “ Materials

Photinus; and Dr. Sharp communicated a paper entitled ‘On some

Mr. F. P. Pascoe exhibited several species of scorpions @ propos of a 
controversy which has recently been going on in ‘Nature,’ respecting a 
statement that scorpions are in the habit of stinging themselves to death 
when in the midst of a circle of fire from which they are unable to escape. 
He pointed out that the two common European species, Scorpio europaus 
and Buthus occitanus, were almost physically incapable of reaching a vital 
part owing to the shortness of the tail or post-abdomen, and thought 
there must be some error of observation with those who asserted the 
contrary. From his own experience, he believed that scorpions were only
