1 74 LEPIDOP TERA . 



three segments ; the dorsal area is really of two shades, 

 yellowish flesh-colonr towards the dorsal line — which is white, 

 slender, enclosed between two fine blackish lines — clear 

 yellowish close to the subdorsal — which is slender, white, 

 edged below by a very slender brownish line, and above by a 

 conspicuous black-brown interrupted line, shading to browner 

 on the back part of each segment — raised dots minute and 

 inconspicuous ; dorsal plate slightly shining, pale yellow- 

 brown, traversed by the yellowish-white beginnings of the 

 dorsal and subdorsal lines. When just hatched, uniform 

 pale grey or greenish-grey, with the back of the thoracic 

 segments darker; head horny, orange-brown. As it feeds 

 it becomes greener in colour. After the first moult the 

 lines begin to appear, and the change to the adult colouring 

 is very gradually assumed. (Adapted from a full description 

 by Mr. L. B. Prout.) 



September or October to the end of April, on common 

 grasses, especially those growing in marshy places. Mr. 

 Prout's larva3 became full grown in January, indoors, and 

 under a high temperature, which ultimately proved fatal to 

 them. 



Pupa reddish-brown, in the earth. Not more particularly 

 described. 



The moth appears to agree in habits with the allied species. 

 At dusk, especiall}^ on damp misty evenings, it will come, in 

 its very restricted haunts, to sugar, and to the flowers of 

 ragwort and wood-sage {Tciicrium scorodonici). 



The first examples noticed and recorded in this country 

 were taken at Folkestone, Kent, in August and October 

 1868, respectively, by Messrs. T. H. Briggs and C. A. Briggs. 

 When attention was drawn to these Mr. T. H. Allis, of York, 

 discovered that among insects taken by himself at Yaxley, 

 Cambs., in 1862 or 1864, was a single specimen of this 

 species which he had passed over as a small variety of L. 

 litlmrgyria. This is curious, since no subsequent capture of
