72, THE ENTOMOLOGIST’S RECORD. 
these late larve are exposed to the uncertainties of our winter, and a 
severe frost or a few days of continued cold and wet, and the whole 
brood is exterminated, although occasionally a few odd larve appear 
to survive a mild winter in a state of hybernation, in some sheltered 
spots on our southern coasts. This was so in the winters of 1877- 
1878, and 1892-1893; but the imagines that these produced appear to 
have been wanting in vitality, and unable to reproduce an autumn brood. 
In 1877 and 1892, when C. edusa was with us, literally in millions in 
August, we saw as many as a dozen hustling one another for the 
honied delights of a single clover flower, and although they were found 
flying about the outskirts of our towns until late in November, their 
progeny was practically exterminated during the few succeeding weeks; 
whilst from the immense multitude of feeding larve that must have been 
in existence in November, 1877, only a few solitary imagines as we 
have already stated, appeared the following year, and with the excep- 
tion of a few isolated specimens none were seen in England for the 
next fifteen years. 
It may be here worthy of mention that, in 1899, CU. edusa was 
comparatively scarce in England, yet it was more abundant in Ireland 
than it had been for very many years, especially in the south-western 
counties—arrivals were seen in early June, their progeny began to 
emerge at the end of July, and yet another brood in late September 
and early October (Wolfe, Irish Naturalist, vill., pp. 218-220). Crutt- 
well records a remarkable fact about the August emergence of this 
flight at Renvyle, on the Galway coast, for of a large assemblage (several 
hundred specimens) which had established itself along a narrow strip 
of flowery meadow land, about half a mile in length, he was unable 
during several days to detect a single female specimen. 
That CU. edusa is abundant in the Mediterranean region from Febru- 
ary to May is a well-known fact. Walker says that it is on the wing at 
Gibraltar all the year round (Hnt. Ivec., vil., p. 258). It is recorded as 
abundant at Tangier in February, at Lambessa in February, along the 
Riviera in February and March, &c. (Hnt. Rec., vil., pp. 251-8 ; vill., pp. 
36-37). That the insect has a remarkable power of flight is well known, 
and when the writer’s British Butterflies was published, the reviewer of 
one of the leading daily papers had only two objections to offer, one of 
which was that the author did not state that CU. edusa was the swiftest 
British butterfly, and that one of Alpheraky’s dragoons rode over two 
miles before he could capture a specimen of C. aurora. Longstaff 
notes U. edusa flying over the Pass de Teyde, on Tenerife, ata height of 
10,000ft., whilst in August, 1898, we ourselves saw a specimen™madly 
careering high over the summit of the Mont Cenis pass, travelling from 
France into Italy, and at an elevation (above 7000ft.) quite out of the 
ordinary range of this species.

The striking resemblances of the guests to their hosts, ‘“‘ Myrme- 
koidie’’ (ant mimicry), vary even more than the formations of the 
antenne. Both true and pseudo mimicry are to be found in the 
guests, the latter is to be found in Scydmaenidae and Anthicidae. The
