NOTES ON EUPITHECIA LA RY.E. 145 



slis^ht earthen cocoon, has the thorax and wing-cases pale 

 yellow ; abdomen short, yellow; tip red, divisions slightly po. 

 The perfect insect appears in April and May, and again in 

 July and August. 



Eupithecia coronata. This larva is, I think, the prettiest 

 of all the genus. It is excessively variable in colour, so 

 much so that it was not till I had repeatedly bred the insect 

 that I could believe that such different looking larvae could 

 produce the same moth. The following are some of the 

 principal varieties: — 



Var. 1. Ground-colour yellowish-green, with three reddish 

 dorsal lines, the centre one interrupted, and sometimes en- 

 larged into a chain of lozenge-shaped spots, the two side ones 

 very indistinct. Body, when closely examined, very slightly 

 hairy. 



Var. 2. Ground-colour one uniform sea-green. The 

 dorsal lines and spots wholly, or almost entirely, wanting. 



Var. 3. Ground-colour greenish-yellow, with a series of 

 rusty, lozenge-shaped dorsal spots or bars. The sides and 

 belly more or less suffused with rust-colour. Segmental 

 divisions bright yellow. 



Var. 4. Ground-colour bright yellow, with a series of 

 broad, dull, red dorsal bars, intersected and bordered by 

 lines of the same colour. Sides and belly thickly clouded 

 with red. This larva is somewhat different in gait and shape 

 from those of all the other Eu])itheci(B, and resembles that 

 of ^. rupicaprarin. Its favourite food is the petals of Cte- 

 matis Vitalba, from which plant it may be beaten in some 



merged in the central line on the anterior and posterior segments. Sub- 

 dorsal lines olive ; two on each side. Belly pale dirty-green, dusky at 

 the edges. The spots and lines vary much in intensity of colouring, 

 and are sometimes almost entirely wanting, leaving the larva a uniform 

 pale yellowish- green.
