96 EUBOLIA MENSURARIA. 



Eubolia MENSURARIA. 

 Plate CXLV, fig. 2. 



In the middle of June, 1872, Mr. Greasley, of 

 Wallasey, sent me a supply of full-grown larvse of 

 this species, from which I took down notes as 

 follows : 



Length about an inch, and rather stout in pro- 

 portion. Head the same width as the second, but 

 narrower than the third segment ; it has the lobes 

 rounded, but the face is square and flat ; there is a 

 slight notch on the crown. The body has the sides 

 swollen into a puckered spiracular ridge, which gives 

 it a rather flattened appearance, both from above and 

 below ; the middle segments are the widest, and it 

 tapers considerably towards the head anteriorly, and 

 from the tenth segment posteriorly. The segments 

 overlap, making the divisions distinct. Skin tough 

 and puckered. The ground colour is pinkish-grey, 

 tinged with pale slaty-blue ; the head is pinkish-grey, 

 freckled with black. The medio-dorsal line is slaty- 

 blue ; the subdorsal lines are pale ochreous-yellow, 

 narrowly edged above and below with pale brown ; 

 the swollen ridge along the spiracles is pinkish ; the 

 spiracles and dorsal dots are black. The ground 

 colour of the ventral surface is pale slaty-grey ; there 

 is a pale ochreous medio-ventral stripe, throughout 

 which extends a narrow pinkish line ; and between 

 this medio-ventral stripe and the spiracular region is 

 another pale ochreous stripe, edged on each side with 

 black, the outer line being broader and more distinct 

 than the inner ; the legs and claspers pinkish-grey. 



Feeds on Vicia, and probably a number of low 

 plants and grasses. 



The imagos appeared from the 9th to the 31st of 

 July, 1872. (George T. Porritt, 3rd March, 1873; 

 Entom., April, 1873, VI, 361.)
