172 THE ENTOMOLOGIST. 



captains that as he was sailing down one of the rivers in 

 Brazil these wasps were attracted in such numbers by his 

 savoury cargo as to prove a terrible annoyance to all persons 

 on board, and that considerable numbers of the wasps had 

 continued on board the whole of the voyage home. It was a 

 remarkable circumstance, that subsequently came to my 

 knowledge, that specimens of the same species of wasp, 

 Polistes higuttatus, were also taken at Liverpool and in the 

 London Docks the same season. 



The above clearly points to the way in which these 

 hymenopterous insects were imported ; and we can, on 

 calling to mind the various kinds of freight conveyed from 

 all parts of the world, readily account for the introduction 

 of insects of other orders, some of which, as we well know, 

 have been so long acclimatised as to have taken their place 

 in the lists of our indigenous insects. 



Among the letters some have neither date nor address, but 

 are no doubt arranged chronologically ; sometimes internal 

 evidence, and sometimes the date of the postmark, supplying 

 the necessary information. The correspondence commences 

 in 1818 and terminates in 1831. 



Lepidoptera. 



"The swallow-tail, Machaon, was found in the caterpillar 

 state feeding on carrots in a garden adjoining some marshes, 

 nnar Deal, July 7th. It changed into a chrysalis in a few 

 days; and the butterfly appeared in nineteen days. — iMiss 

 Harvey; Upper Deal." 



" In your last number I observe you say there is no 

 authentic specimen of Podalirius known. I beg leave to 

 state there is one in my possession unset, and taken at 

 Netley ; and as there existed doubls about its being a native 

 I have kept it just as I captured it; its larvae, of which I have 

 had two, feed on the wild white plum tree. One of these days 

 1 hope to add it to other collections. — Rev. F. W. Hope; 

 July 8, 1827." 



"An account was sent to you, 1 believe, by my friend 

 E. Hornor, of the capture of a pair of P. Podalirius. The 

 gentleman by whom they were taken, and who resides at 

 Sunderland, says that he caught them several years ago in a 

 wood near Oxford. He showed them to a person who lived 

 near, and he tuld him that he had seen several of that kind 

 in the same wood. The gentleman who captured them was 

 110 entomologist himself, and could not be interested iii
