yellowish-green, with purplish-pink longitudinal lines and 

 the head pale green. 



? to March and April on Dadijlis glomerata (cocks-foot 

 grass) and probably on other stout grasses, mining within 

 the stems — Mr. Porritt says head downwards — and also that 

 on damp evenings it will come out and sit on the tips of the 

 blades of the grass. A writer in the E)itoiiwlugists Weekly 

 Intelligencer^ 1861, stated that he had found several larvas of 

 this insect feeding in the unexpanded buds of a large Carcx^ 

 but no indication is given of the species, nor any proof that 

 it was not a large grass in which they were observed. 



Pupa undescribed. 



The moth hides in the daytime, occasionally in a chink of 

 a fence, paling, post or wall, or under a coping, but usually 

 among grass on the ground. It flies at dusk and comes freely 

 to sugar, houeydew and any form of sweet. Very abundant 

 throughout England and Wales, the brighter forms predomi- 

 natine- in the southern counties, the black in the north and 

 also in the Cambridgeshire Fens. Common also in Scotland, 

 extending northward to Moray and West Ross, but not yet 

 noticed in the Islands. Apparently found in all parts of 

 Ireland, and in many of them abundant. Abroad it is met 

 with throughout the temperate portions of Northern Europe, 

 Central Europe, Northern Italy, Southern Russia, Armenia 

 and Asia Minor. Also certainly in some parts of North 

 America, since specimens were taken in Vancouver Island 

 by Mr. J. J. Walker, R.N.
