Very rare; one exam pie taken by Mr. Matthews under bark of dead Plnus sylvestris 

 at Bakewell, Derbyshire ; it has also once been taken by Mr. Crotch. 



This species may be known by its broader form, and by having the 

 thorax feebly constricted behind with the posterior angles nearly right 

 angles, and also by the sculpture of the eljtra, which are dilated and 

 broadest behind. 



The female has the elytra suffused with darker colour which takes
