176 THE INSECTS OF ALDERNEY. 



from June 23rd to 30th, 1873 ; from August 4th to 9th, 1892 ; 

 and September 23rd of the present year. To these I have 

 added the species mentioned by the Rev. F. A. Walker. 

 Butterflies, as a rule, appear to be scarce, but on the occasion 

 of my visit in 1892, I found two species, viz., Colzas Edusa 

 (the Clouded Yellow) and Pyrameis cardui (the Painted Lady), 

 swarming all over the island. I have never seen so many of 

 these species together before or since. 



The following species, mentioned on the list, have not 

 hitherto been taken in Guernsey. 



Chaerocampa porcellus. Derephysia foliacea. 



Pelurga comitata. Tiphia femorata. 



Doratura stylata. Pompilus unicolor. 



Podops inunctus. Odynerus quadratus. 



Salda Cocksii. P. chalybeatus. 

 Berytus signoreti.
