THE GEOUP OF EUFICOENIS. 53 



cinium myrtillus during June and July (I have found 

 them in August), living solitary and are very lazy. The 

 body is spindle shaped ; the head is broad above, and 

 if viewed from the front, appears almost triangular. 

 The ground colour is a beautiful brick red, with a dark 

 brown dorsal stripe. On the fifth and following seg- 

 ments are, on each side, oblique stripes of the same 

 colour, proceeding towards the posterior ; and on the 

 same parts the dorsal stripe appears on both sides 

 enclosed by clear, almost white lines. Out from these 

 each segment bears (with the exception of the three 

 posterior) two transverse rows of brown tubercles, 

 and there is a row of dots over the ventral legs, while 

 over the thoracic legs is a brownish line. On each 

 side of the head from the eyes, across the vertex, is a 

 brownish stripe, and the vertex, the clypeus, and mouth 

 parts are of the same colour. 



The larvas pupate in the ground, and there seem to 

 be two generations in the year. Opius grcecus, Wesm., 

 is parasitic on them. 



Not common. I only know of it from Gadder 

 Wilderness near Glasgow, Kingussie, and Wimbledon 

 (Bridgman). The imago appears in June and August. 



Its continental distribution is wide. France, Scandi- 

 navia, Lapland, Finland, Prussia, Germany, Russia, 

 Orenburg (Ural) and Riga.
