Carpophilus sexpustulalus F. in the British Isles. 145 



e.g., Attagenns pellio and Trox scaher, are undoubtedly very 

 much more numerous than the comparatively few and isolated 

 records would lead us to suppose. From a careful study of 

 the facts in all their bearings, and my knowledge of the dis- 

 trict, I conclude that the species is indigenous, or alternatively, 

 that if it has been introduced, that such introduction is 

 sufficiently remote for it to have become well established. 



In closing this article, I think the Jollowing summary of the 

 Yorkshire specimens may be useful : — 



One specimen, Edlington Wood, 1894 (E. G. B.). 



One specimen, Sandal Beat Wood, 1904 (H. H. C). 



Eight specimens, Wheatley Wood, 1907 (E. G. B., H. H. C.,. 

 V. C). 



One specimen, Cusworth, 1907 (H. H. C). 



Four specimens, Edlington Wood, 191 1 (H. H. C). 



Eight or ten specimens, Edhngton Wood, 1911 (W. E. S.). 



Three specimens, Sandal Beat Wood, 1912 (H. H. C). 

 The initials are those of Dr. Corbett, his son, Mr. Sharp and 

 myself. 



Amongst themselves the specimens differ in the size of the 

 spots, which are occasionally reduced to such a degree as to 

 be seen with difficulty by unaided sight. 



The problem raised by the capture of C. obsoleius is an in- 

 teresting one, but there is as yet not sufficient evidence to 

 discuss it satisfactorily. 



Bird Notes from the Scarborough District. — I found 

 the first full clutch of Lapwing's eggs on April 7th. Nests 

 had been ready for a week or ten days, but laying had evidently 

 been delayed, owing, perhaps, to the cold winds. Woodcock 

 seem to be more numerous than usual in this district. I put 

 up three on April loth and two on April 7th in different locali- 

 ties. On April 14th I found a Snipe's nest with four eggs, an 

 early date for this district. — Stanley Crook. 



At a recent meeting of the Lancashire and Cheshire Entomological 

 Society, Mr. W. Mansbridge gave the results of his breeding experiments 

 with the Black Race of Boarmia repandata (var. nigra), and summarised 

 the results as follows : — In 1909 {a) a wild $ of the local type form gave 

 all var. nigra ; [b) a wild § var. nigra gave all black moths ; (c) a pairing 

 of nigra ^ and type $ gave all types. In 1910 (a) type x type gave 66-6 

 per cent, type, and 33-3 per cent. var. nigra ; [b) nigra x nigra gave 92 per 

 cent, nigra and 8 per cent, type ; and (c) nigra x nigra gave 96 per cent. 

 nigra and 4 per cent, type ; while in 191 1 [a] type x type gave all type ; 

 (b) nigra (J x type § gave all nigra] (c) nigra x nigra gave 95-7 per cent. 

 nigra and 4-3 per cent, type, and {d) x second experiment of the same 

 gave 70-5 per cent, nigra and 29-5 per cent. type. In 1910 moths from 

 the broods a and c were used for the cross pairings of type and variety, 

 the others being inbred, and in 191 1 all were inbred.
