HETEROCERA 



Of the 2,014 species of Heterocera or moths recorded in South's 

 list, rather more than 1,300 have been recorded from Lancashire. 



Sphingid^ 



Acherontia atropos, L. Generally dis- 

 tributed and sometimes common in 

 potato districts 



Sphinx convolvuli, L. Generally distributed 

 but very irregular in appearance ; 

 one specimen of S. ligustri, L., has 

 been recorded from near Charley 



Deilephila galii, SchifiF. Has appeared in 

 some numbers on the sandhills 

 during certain years. The last of 

 these was 1888. Previous years 

 were 1870, 1859 and 1834. Afew 

 larvse were taken by Rev. A. M. 

 Moss also in 1897. For these ap- 

 parently irregular manifestations an 

 explanation has been sought in a 

 theory of continental immigration, 

 which however seems hardly ade- 

 quate to support the facts of the 

 case. More probably this moth 

 persists in small numbers from year 

 to year in suitable localities, and its 

 years of abundance are caused by 

 a concatenation of particularly 

 favourable phenological conditions 

 extending probably over more than 

 one year. (The subject is discussed 

 more in detail in a paper by the 

 present author contributed to the 

 Liverpool Biological Society. See 

 Trans, vol. vii. ' Occasional Abund- 

 ance of Insects ')
