100 Mr. 0. B. VVillianis' Records of 



C. leikis was very coiunioji about the year ItlGS, but was 

 rare for the next ten years. 



1878. According to the same authority {loc. cil.) the 

 moth was agaui abundant in 1878. He describes how in 

 October of that year " on Forres Park Estate, Claxton Bay, 

 hundreds of these Urania filed soklier-like over the roof 

 of my hut in one continuous string from 4 to 6 p.m., flying 

 ui a Southerly direction. Where could they be going to ? 

 They were evidently on a long journey, for I watched them 

 as far as the eye could reach, and saw them passing over 

 several of our small hills without hiterrupting their course. 

 It is quite possible that they were emigrating, for their 

 course being southerly they would reach Icacos [south- 

 western promontory], and from there return to Venezuela 

 across the Serpent's Mouth. Since then I have not seen 

 them in such large quantities ; they appear every year, but 

 in smaller numbers." 



1891. Caracciolo {loc. cil.) writes ; " One day last 

 September [1891] I observed them very closely. They 

 were passing over the roof of the customs house, and flying 

 about three feet over the surface of the sea. Occasionally 

 they would swoop down and tip the surface of the water. 

 Since writing the above Mr. Clupjjy assures me that he 

 came across one by Caledonia Island floating on the sea." 

 No direction of flight is given in this account. 



1899. In a letter, Mr. T. I. Potter informs me " the 

 most important migration of C. leilus that I can remember 

 was that of 1899, July to October. The day-moths flew 

 in thousands from N.W. to S.E. at Brighton — apparently 

 crossing the gulf from Venezuela. They were very common 

 on the Queen's Park Savamiah [Port-of-Spain] that year, 

 also flying from N.E. to S.W. in the morning and vice 

 versa in' the evening." " I cannot now recollect whether 

 they reversed their flight at Brighton in the afternoon, and 

 I don't think I noticed this. I know they flew down there 

 very late in the evening, because I used to catch specimens 

 on my dinuig-table after dark." 



1901. In this year the moth again appeared in large 

 numbers. P. L. Guppy (Trans. Ent. Soc, 1907, pp. 405- 

 410) has given some notes on this migration from which 

 the following extracts are taken : — 



" From the early part of September we had them here 

 by thousands, lasting for about five weeks." ..." Flying 

 both eastward and westward and seen a mile out at sea "
