"pale)." Probably the discrepancy in colour arises from the age of 

 the larva described. The other food plants of angustana mentioned 

 are flowers of Achillea and Origanum, and no light is yet thrown upon 

 the food plant or larva of the (supposed) second brood of this species 

 found abundantly on heaths where the (supposed) first brood is never 

 seen ! 



Eiqjcecilia curvistrigana, "Wilk. — Larva short and rather stumpy, 

 thickest in the middle, not active, pale yellowish-pink, but deeper pink 

 when full grown, with grey internal dorsal vessel ; hairs very delicate, 

 spiracles pink. Head light brown, eyes and jaws blackish, plates pale 

 amber colour. In flowers of Solidago virgaurea, eating out the young 

 seeds and passing from flower to flower, sometimes uniting them slightly 

 with silk. When full grown, leaving the flowers and spinning a tough 

 cocoon among rubbish or rotten wood. 



I found larvae in September of last year, but failed to rear them. 

 This autumn I haA-e a good number, with which I hope for better suc- 

 cess. Mr. Machin has reared a few specimens annually for the last 

 few years, but finds them very scarce. 



EiipoeciUa affinitana, Doug. — This species was reared from flowers 

 of Aster tripoUum by Von Heinemann some years ago, and since by 

 several English entomologists, but I am not aware that any description 

 of the larva has been published. It is stumpy, sluggish, dirty whitish, 

 faintly tinged on the back with grey, through which the dorsal line is 

 visible, and with a faint grey spiracular line. Head brown, dorsal plate 

 black, anal plate pale brown. In blossoms and seed-heads of Aster 

 tripolium, eating out the young seeds and doubtless moving to a fresh 

 head when the food is exhausted, and quitting the seed-heads to spin 

 up. As its food plant is apt to be submerged at high spring tides, it 

 must either travel some distance to spin up, or make a cocoon which 

 enables it to set salt water at defiance. I found a few larvse at the 

 end of September last year, and reared two specimens in July last. 

 At the end of July I found larvse, from which I expected to rear a 

 second brood in August, but was disappointed, and suppose they are 

 lying over until next spring. I cannot blame them for this, for the 

 weather last August in this neighbourhood was not attractive. 



Eupcpcilia implicitana, H.-S. — The food plants of this species have 

 already been recorded by several writers, but my friend, Mr. W. West, 

 of Greenwich, has supplied me with so interesting an account of the 

 habits of its larva, that I make no apology for reproducing his obser- 

 vations. He says, " The food is the common chamomile {Pyretlirum 

 " inodorum) ; the larvse feed in the seed-heads and also in the stems,
