52 THE ENTOJrOLOGIST. - - 



j-eai's I had opportunity of seeing the species in that locality, it 

 was not out till late in August, and was noticed in some 

 numbers the first week in September, at which time hellargus 

 was also observed. The two species often occur in the same 

 districts, and sometimes even in the same localities in those 

 districts, as instanced above ; but I am inclined to suppose that 

 each has its particular settlement or colony. I have been unable 

 to verify this, however, and the information obtained from others 

 upon tlie point is somewhat indefinite. The few specimens of 

 hellargus I have taken (at Ventnor only) were obtained within a 

 sliort distance of corydon head-quarters, and stray examples of 

 the last-named species were in each instance disporting themselves 

 around and about. I first supposed the hellargus captured at 

 such times were precocious individuals, and expected that as the 

 number of corydon diminished that of hellargus would increase ; 

 but such was not the case. Corydon disappeared from the scene, 

 but it was not replaced by hellargus; and I therefore concluded 

 that the odd examples of hellargus were, like the corydon flying 

 with them, wanderers from their respective head-quarters. 



Note. — In referring to the under-side variation (ante, pp. 0, 7), 

 I omitted to mention the occurrence of an extra basal ocellus on 

 the inner margins of hind wings, vide figs. 7, 10, PL I.

THE CRAMBUS CONTAMINELLUS DISCUSSION ; WITH 

 DESCRIPTION OF CRAMBUS SALINELLUS, mihi. 



By J. W. TuTT, F.E.S. 



After Mr. Tugwell's communication, giving Mr. W. H. B 

 Fletcher's opinion as to the nomenclature of Cramhus contami- 

 nellus, had been published (Entom. xix. 169), I wrote to that 

 gentleman and asked him to work out the matter fully, as I 

 thought it advisable to come to some definite conclusion, and his 

 final opinion would at once dispose of the matter. On November 

 15th, 1880, following a splendid consignment of the salt-marsh 

 species, I received a letter from Mr. Fletcher, which I consider 

 effectually settles the discussion, and confirms his previous opinion ; 

 and as I knew the letter would be most interesting to all collectors 

 of the CrambidiT, I Isave since obtained his permission to publish
