this report I have marked with an asterisk species which do not 

 appear to have been previously recorded for Yorkshire : —

 September (W. C. Hey). 



Calathus melanocephalus L. var. nubigena Hal. Upper 

 Teesdale, near the summit of Mickle Fell in May (M. L. 

 Thompson). 



Calathus micropterus Duft. Upper Teesdale, near Cronkley, 

 in September (M. L. Thompson). 



Pristonychus terricola Herbst. Among sand and clay on the

of a moorland stream near Cronkley in September (M. L.
