NOTES ON EUPITHECIA LARV^. 131 



whitish, with a central purplish line running the whole length. 

 Feeds in September and October on the flowers and seeds 

 of yarrow {Achillea mUlefoUimi). Pupa enclosed in an 

 earthen cocoon ; uniform orange-red, thorax and wing- 

 cases paler than abdomen. Tip of latter blood-red. Long, 

 rather slender and tapering. Abdominal divisions deep red. 

 Wing-cases much furrowed. The perfect insect appears in 

 June and July. I prefer retaining the name E. suhjidvataf 

 as the foregoing description was taken from larvae reared 

 from eggs of the so-called variety of JE. succentariata. I 

 shall continue to believe that the two insects are distinct 

 species till some person breeds one from the egg of the other. 

 I never heard that this has been done. The exhibition of a 

 long series of varieties running one into the other proves 

 nothing at all. It has never been my good fortune to be in 

 a locality where E. succentariata occurred, so th;:t I have 

 never been able to try the experiment. I shall feel deeply 

 indebted to any gentleman who is in the habit of taking this 

 insect, if he will send me a few e^Q-s or a livino; female. 



Eupithecia mhumhrata. Var. 1. Yery long and slender, 

 tapering very much towards the head. Ground-colour dull 

 yellowish-green. Central dorsal line broad, dai'k green, 

 narrower at the segmental divisions. Sub-dorsal lines 

 dusky, very narrow and indistinct. Dorsal segmental di- 

 visions orange. Ventral ditto yellow. Spiracular line dusky 

 green. On each side of the head and anal segment a yel- 

 lowish line. 



Var. 2. Ground-colour dirty greenish-brown. Central 

 dorsal line dusky olive. Sub-dorsal lines ditto, nai-row. 

 Posterior segments reddish. In other respects resembles 

 Var. 1. 



This singular long thin larva, I have been in the habit of 

 taking at intervals for some years past in Buckinghamshire.
