35& Day : Cumberland Dragonflies. 



be freely observed shooting like an arrow over the pools and 

 ditches. It occurs from the end of June to late September. 



sE. cyanea Mull. Scarce. I have only taken two specimens 

 myself — both near Carlisle. It is more southerly in its range 

 than the preceding species.* 



Calopteryx virgo Linn. Frequents the edges of small 

 streams which are fringed with osiers and alders. My only 

 localities are the River Petteril near Carlisle, and the Derwent 

 near Seathwaite. It is on the wing in June and July. I have 

 not, however, seen it for some years, and have always con- 

 sidered it a rather scarce insect. 



Pyrrhosoma nymphula Sulz. Common and widely distrib- 

 uted in this county, frequenting heaths, streamsides, and 

 marshy ground in fir woods. I have even taken it in my 

 garden. It seems most at home among the ponds on the 

 peat mosses, its beautiful crimson colour (when mature) being 

 very striking. It occurs from May to August. 



Ischnura elegans Lind. One of our commonest species, 

 occurring similarly to the last. Very abundant at the Black 

 dub near Carlisle, and on Solway Moss. The middle of June 

 is its usual time, but it lingers until August. 



Agrion pulchellum Lind. Newton Reigny Moss near 

 Penrith, June 25th, 1905, four specimens. It is possible this 

 species may occur more generally. It may easily be overlooked 

 for the closely, allied A. puella. 



A. puella Linn. Common. I have found it all over the 

 county. 



Enallagma cyathigerum Charp. Somewhat uncommon. I 

 have it from Solway Moss, and Kingmoor, and it has occurred 

 near Brampton and Keswick. My captures were made in June. 



MOLLUSC A. 

 Vitrea Jucida at Louth, Lines. — About 1-30 p.m. on 

 September 20th, my youngest daughter called my attention 

 to a ' snail ' crawling up the wall in our yard at 46 Westgate, 

 Louth. This was a fine specimen of Vitrea lucida ; when 

 crawling the animal measured, from posterior extremity to tip 

 of tentacle, 32 mm. ; the animal and shell, alive, weighed 

 11 grains, the shell only 3 grains. Breadth of shell (greatest 

 diameter) 16 mm., (smallest) 14 mm. ; height of shell, 7 mm. 

 When found, a number of mites were running about the animal. 

 I believe this is only the second specimen recorded for the 

 county. — C. S. Carter, Louth. 



* In my experience JEschna cyavrea is much commoner in Yorkshire 

 than is /£. j'uncea, especially in the southern division. This year, how- 

 ever, Dr. W. J. Fordh m found JE. juncea in plenty on September 4th, 

 at Bishopdale, near Buckden. — G.T.P.
