72 THE entomologist's record. 



these late larvae 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 larvffi 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 (J. cdusa 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 larvas 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, ('. ('(hisa 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 OctolDer (Wolfe, Irish XatHralist, viii., 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 t '. ediisa is abundant in the Mediterranean region from Febru- 

 ary to May is a well-known fact. Walker says that it is on the Aving at 

 Gibraltar all the year round {J-^]it. Ilcc, vii., p. 253). It is recorded as 

 abundant at Tangier in February, at Lambessa in February, along the 

 Riviera in February and March, &c. {Ihit. Fwc, vii., pp. 251-3 ; viii., pp. 

 36-37). That the insect has a remarkable power of flight is well known, 

 and when the WTiter's British Bittterjiies was published, the reviewer of 

 one of the leading daily papers had only two objections to oft'er, one of 

 which was that the author did not state that C. cditm 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 (-'. eilut^a flying over the Pass de Teyde, on Tenerife, at a 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 

 antennae. Both true and pseudo mimicry are to be found in the 

 guests, the latter is to be found in Scydmaenidac and Anthicidae, The
