ENIGMAS STILL UNANSWERED. 161 



27. " A Gelechia ? larva, feeding in the heads of yarrow 

 {Achillea millefolium)" 



31. "A Coleophora larva, feeding on Vaccinium Myr- 

 tillus in a longish slender case, somewhat like that of Vimi- 

 netella." Professor Zeller thinks that this should be C. 

 orbitella. 



33. " A brown Gelechia-like larva, found amongst moss 

 by Mr. Douglas in March, 1857." 



37. " A Coleophora larva, found on birch at West Wick- 

 ham, October 31st, 1857, in a case which had much the 

 appearance of a birch bud." 



38. " A Lithocolletis, mining the upperside of beech 

 leaves." 



41. "A Gelechia? larva, long and thin, of a pale dull 

 yellowish ; feeding on thyme, eating the leaves half through 

 from the underside, and concealing itself in tubes of sand, 

 spun together with silk." Professor Zeller has this year 

 bred JButalis siccella, and he believes from the above-men- 

 tioned larvae. 



NEW ENIGMAS FOR SOLUTION. 



46. A pretty red-spotted yellow larva mining a leaf of 

 Car ex riparia, found at Hackney, March 29th. Is there 

 any possibility of this being Cosmopteryx Lienigiella? 

 Only one larva was found, and that escaped when half 

 figured; Cosmopteryx larvae are excessively apt to crawl 

 away.
