154. The Small Grass Emerald (Nemoria viridata). 



154. THE SMALL GRASS EMERALD. The 

 antennae are simple in both sexes : the wings 

 are dingy green, often suffused with a reddish 

 tinge : the fore wings have one very distinct, 

 transverse, oblique, whitish line beyond the 

 middle, and a second very indistinct and 

 shorter transverse line nearer the base : this 

 second or inner line is frequently wanting : 

 hind wings with a slight angle near the 

 middle of the hind margin, and an oblique 

 whitish line across the middle of the wing, 

 meeting the principal white line on the fore 

 wings: crown of the head whitish; thorax 

 and body dull dingy green. 



The MOTH appears on the wing in May and 

 June, and has been taken in Devonshire, 

 Dorsetshire, Hampshire, Worcestershire, Lan- 

 cashire, and the Lake District generally, anr 1 

 Mr. Bristow is said to have taken it in the 

 county Wicklow, in Ireland. (The scientific 

 name is Nemoria viridata.) 



155. The Small Emerald (lodis vernaria). 



155. THE SMALL EMERALD. The antennae 

 are ciliated in the male, simple in the female ; 

 the wings of the most lovely green; the fore- 

 wings with two, the hind wings with one, 

 very distinct, white, transverse lines ; the 

 head, thorax, and body delicate green. 



The CATERPILLAR has a porrected head, 

 deeply notched on the crown; the body is 

 green, with two whitish stripes on each side. 

 It feeds on the traveller's joy (Clematis 

 vitaiba). 



The MOTH appears on the wing in July, and 

 has been taken in Devonshire, Dorsetshire, 



Sussex, Surrey, Essex, Kenr, Buckingham- 

 shire, Gloucestershire, Herefordshire, and 

 Worcestershire ; of course it only occurs 

 where the clematis is abundant. (The scientific 

 name is lodis vernaria.) 



156. The Little Emerald (lodis lactearia). 



156. The LITTLE EMERALD. The antennae 

 are distinctly ciliated in the male, oimp'e in 

 the female ; the wings are white ; but when 

 the moth first emerges from the chrysalis, 

 tinged with the most lovely green ; a trans- 

 verse and oblique, but nearly straight, line, 

 whiter than the ground colour, across the 

 wing at two-thirds of the distance passes 

 between the base and hind margin ; this 

 white line is continued in the same direction 

 across the hind wing : the antennae, head, 

 thorax, and body are white, or almost so. 



The MOTH appears upon the wing a little 

 before Midsummer, and occurs in most of our 

 English counties, and in some localities in 

 Scotland. Mr. Birchall says it is generally 

 distributed in Ireland. (The scientific name 

 is lodis lactearia.) 



157. The Blotched Emerald (Phorodesma bajularia). 



157. THE BLOTCHED EMERALD. The an- 

 tennae are ciliated in the male, simple in the 

 female ; the wings green ; the fore winga 

 with two slender transverse whitish lines 

 that nearest the base of the wing is somewhat 

 waved, the outer one is slightly zigzaj?, and 

 terminates in a large, squarish, pale blotch 

 near the anal angle ; this blotch is dingy 

 white, but tinged with red-brown in the 

 middle ; the fringe is white, spotted with
