A LIST OF THE NOCTURNAL MACRO-LEPIDOPTERA 

 INHABITING THE ISLANDS OF GUERNSEY, 

 ALDERNEY, SARK AND HERM, WITH NOTICES 

 OF THEIR OCCURRENCE. 



By Mr. W. A. Luff. 



In the year 1873, I contributed a list of the Macro-Lepi- 

 doptera of Guernsey and Sark, to the 4 4 Entomologist," and 

 then had the valuable assistance of the late Mr. Edward New- 

 man, and the late Mr. Henry Doubleday, in the determination 

 of some of the more difficult species ; since that time I have 

 made many additions to the list, and have brought the number 

 up to 248, (or including the Butterflies, which have already 

 formed the subject of a separate paper) 277 species. 



If the Micro-Lepidoptera were added, these figures would 

 be very likely doubled. 



This result in one small section of the class Insecta is a 

 sufficient answer to the statement made in one of our former 

 popular " Guernsey Guide Books," that " The Entomology of 

 Guernsey presents little to tempt the forceps or the net of the 

 English collectors." 



Amongst the moths enumerated, are some very rare and 

 local species. Three at least have never been known to occur 

 in Great Britain or Ireland, whilst others are rarely seen indeed. 



The three species referred to are : — Agrotis Crassa, Poly- 

 phsenis Sericina, and Eubolia Peribolata. 



The principal moths of great rarity, or local occurrence in 

 Britain are, Deilephila Euphorbioe, Sphinx Convolvuli, Chsero- 

 campa Celerio, Deiopeia Pulchella, Callimorpha Hera, Leu-
