102 THE ENTOMOLOGIST. 



"Kozensho, Ko-tan-kgan, 6000 ft., ix. 7, 1096." It is about 

 21 mm. long — distinctly smaller than a Japanese example in my 

 collection. I suspect that this species has been introduced into 

 Formosa, as it is wholly absent from the large collection made 

 by Sauter. There is in the Sauter collection a related species 

 with much shorter mandibles. 



CHESHIRE AND SOUTH LANCASHIRE ODONATA. 



By W. J. Lucas, B.A., F.E.S. 



Recently I have seen a collection of dragonflies from 

 Warrington, some belonging to the Municipal Museum, the 

 remainder from Mr. G. A. Dunlop's collection. I record such of 

 the local ones as bear date and locality labels. 



Leucorrhinia dubia. Abbot's Moss, Cheshire : July 4th, 1908 ; 



July 2nd, 1909 ; August 1st, 1910. 

 Sympetrmn Jiaveolimi. A male, Flaxmere : August 5th, 1907. 

 Sympetruvi scoticuvi. Flaxmere, Cheshire : August 5th, 1907 ; 

 August 3rd, 1908. Abbot's Moss : July 4th, 1908 ; August 

 1st, 1910. 

 Calopteryx virgo. Amongst a number of C. virgo and C. splenclens, 

 usually without labels, is a specimen of the former species, 

 which appears to be var. anceps. Whether this is a North 

 Country specimen I cannot say. 

 Lestes sponsa. Abbot's Moss : July 4th, 1908 ; August 1st, 1910. 

 Pyrrhosoma nymphula. Frodsham, Cheshire : June 9th-10th, 



1902 ; July 18th, 1908 ; June 22nd, 1910. 

 Ischnura elegans. Flaxmere : August 5th, 1907. Padgate, South 

 Lancashire : June 16th, 1909. A specimen bred out in the 

 Museum ; May 18th, 1909. 

 Agrion pulchellum. Frodsham : June 9th-10th, 1902. 

 Agrion puella. Frodsham : June 10th, 1902. Grappenhall, 



Cheshire: June 23rd, 1906. Padgate: June 16th, 1909. 

 Enallagma cyathigerum. Abbot's Moss : July 4th, 1908. 

 Perhaps the most interesting specimen is *S'. fiaveolum, but 

 being a male it is most probably a migrant. Mr. Dunlop will 

 no doubt be able to satisfy himself as to whether it breeds in 

 the Delamere Forest District or not. In the collection are two 

 specimens of Agrion pulchellum, labelled " New Forest, 9 July, 

 1895." This species has not, I believe, been recorded for the 

 New Forest, and the record would have been of interest ; but, 

 unfortunately, the specimens were bought at Stevens', and 

 nothing further is known about them. Mr. Dunlop tells me in 

 addition that Mschna grandis and jE. cyanea occur very com- 

 monly in the district, even flying about the streets of Warrington, 

 and that Agrion puella is common on the Old Quay Canal, 

 Acton Grange, Cheshire. 



Kingston-on-Thames: February, 1911,
