P. lineatus. Of the size of spwmarius, and similarly haired, but 
by no means such a common species. It rarely varies from the 
characters given above, the Jength of the crown alone being sufficient to 
separate it from the last named. In the London district it has occurred 
at Weybridge and Beckenham, in July and August. Length, 25 lines. 
The above have all previously been recognised as British; but, as 
campestris is now for the first time brought forward, I give a description 
in detail.
