KMPHYTUS CALCEATUS. 273 



The larva feeds on the common rose and on 

 Idceus during August and September. The larvas 

 which I have had did not bore into pith although that 

 was supplied, but pupated in the earth where they 

 made a cell, the sides of which were neatly smoothed, 

 and perhaps agglutinated together, at least, the cell 

 held together when separated from the surrounding 

 earth. The other authors who have described its 

 transformations have also given this as its mode of 

 pupation, but as they would not have supplied it with 

 stems, the larvae may have adapted themselves merely 

 to the altered circumstances. It has the upper part 

 of the body dark greyish-green, in some cases greyish- 

 black, lighter in the centre of the back ; the sides, from 

 a little above the spiracles, white. The skin is beset 

 closely with little white tubercles arranged in irregular 

 rows. Head pale orange ; eye spots black, mouth pale 

 brown. The upper part of the body varies in the 

 intensity of the colour. 



Trypkon extirpatorius, Gr., and Masicera media, 

 Goureau, are its parasites. 



E. rufocinctus is not, I think, very common. I have 

 taken it in Clydesdale, Rannoch, Braemar and Bonar 

 Bridge. In England it has been taken in "Worcester- 

 shire, Devonshire, Bristol and the London district. 



Continental distribution : Sweden, Germany, Hol- 

 land, France, Italy, Russia.
