PACHYPROTASIS SIMULANS. 123 



moutli brownish, a light brownish band over face, and a 

 dark oblique spot over legs; claws brown, spiracles 

 pale. The anal segment is whitish, and bears a few 

 hairs, while over it is a light blackish mark. 



The larva was discovered by Mr. Fletcher feeding 

 on Srroj'Jut.I'ii'id, <i./n<ifira and Stachys letonica. In 

 Clydesdale it frequents mostly ]vy/^.>v///// fhapsus and 

 Pedicularis in the autumn. It pupates in the earth. 



An extremely abundant species, found everywhere in 

 June and the early part of July. 



Its Continent distribution extends from Lapland to 

 the Mediterranean, and eastward to the Ural Moun- 

 tains and India (cf. Cameron, Trans. Ent. Soc., 1877, 

 88). Apparently, too, P. omega, Norton, a widely 

 distributed form in North America, is the same species.
