THE INSECTS OF ALDEENEY. 



BY MR. W. A. LUFF. 



In the Transactions for 1897, I published a list of the Insects 

 of Alderney as far as then known. 



Through the kindness of Mr. E. D. Marquand, who has 

 taken up his residence in Alderney, with a view to study the 

 Flora more particularly, I am now able to present a much 

 more complete list. 



Mr. E. D. Marquand was ably assisted by his brother, 

 Mr. E. P. Marquand, in the collection of specimens. 



The additions outnumbering the original list, I have 

 thought it advisable to publish a complete catalogue of the 

 Insects now known to occur in the island. 



Four additions have been made to the Butterflies ; of 

 these Satyrus Semele, the grayling, is very local, being 

 observed only on the cliffs near Essex Castle and on the 

 lower part of Butes Hill. On June 17th whilst on a visit to 

 the island I captured two specimens, male and female, both 

 being variations from the usual type, the male being destitute 

 of the usual spots on the upper wings, and the female with 

 an additional spot. Several specimens were taken by Mr. 

 Marquand, later on, but these proved to be of the normal type. 



The additions to the Moths are very interesting ; Sesia 

 musciformis was common on the coast and a specimen of 

 Sesia ichneumoniformis was also taken. A number of larvae 

 of Odonestis potatoria were found on the slopes of Essex 

 Castle and some fine specimens of the moth were bred from 

 them. Mr. Marquand saw several specimens of Callimorpha 

 Hera, but having no net with him at the time did not capture 

 them. A specimen of Liparis salicis, the Satin Moth, was 

 taken in August ; it is not known to occur in Guernsey. 



The Coleoptera or Beetles now number 120 species, 

 many of them being of special interest. Rhizotrogus cestivus 

 is not on the British list. Several specimens of a curious 

 variety of the non-British Cryptocephalus vittatus having no 

 yellow stripe on the elytra, were taken in company with the
