the meclio-dorsal line of paler ground colour. There are no 

 perceptible sub-dorsal or spiracular lines ; spiracles very dis- 

 tinct, black ; ventral surface and prolegs uniformly ochreous- 

 yellow ; legs wainscot-brown. (G. T. Porritt.) 



September to June on Carex glauca, Dactylis glomerata, 

 and other grasses, feeding inside the central culm or grass 

 stem, devouring the immature blossom and burrowing down 

 the heart of the plant to the base, after which it removes to 

 another stem. Also occasionally in flower stems of /m 

 fcetidissima, hollowing out the flower stalk to the bud, which 

 is also eaten out. Another reputed food plant is Elymus 

 arenarivs. 



Pupa half an inch in length, stout in proportion, thorax 

 and wing-covers well developed ; tapering a little toward the 

 anal tip, which is furnished with two slightly diverging 

 points, and surrounded by four very minute curly-tipped 

 bristles ; colour dark chestnut-brown ; surface smooth and 

 shining. (W. Buckler.) In a thin silken cocoon in the eaten- 

 out bud or stem, or in any other convenient dried receptacle. 



The moth conceals itself during the day, doubtless among 

 grass, and flies at rather late dusk, coming freely to sugar, 

 honeydew. and ragwort blossoms. Very partial to hills, 

 rocky places, and fields at the sea-side, and comparatively 

 scarce away from the coast. I find it recorded on the coasts 

 of Kent, Sussex, Dorset, Devon, and Cornwall, though not 

 in all cases abundantly, and inland, scarce in Berkshire and 

 very so on the hills of Surrey ; more plentiful on the coasts 

 of Essex, Suffolk, and Norfolk, and not scarce in the Norfolk 

 and Cambridgeshire Fens ; found also in Warwickshire, 

 Staffordshire, Derbyshire, Herefordshire, Gloucestershire, 

 Somerset, Cheshire, Lancashire, and Lincolnshire, and com- 

 monly in Yorkshire, Durham, Cumberland and Northumber- 

 land. It must surely occur in many parts of Wales, since T 

 found it in I*embrokeshire — yet only very locally, on a rough 

 piece of land at the top of a sea-cliff'. In Scotland it is found
