86 ENIGMAS STILL UNANSWERED. 



Nepticula larva, making brown blotches in birch leaves, 

 occurring at Dartford Heath, Mickleham, &c. ; none have 

 hitherto been reared. 



The following incomplete observations, made during the 

 year 1854, may be considered as so many additional 

 Enigmas. 



11. An Elachista larva, found by Mr. Scott at the end of 

 April, mining in leaves of Sciiyus lacustris. 



12. A Gelechia larva, found by Mr. Scott early in May, 

 mining the leaves of Arctostajyhylos Uva-ursi? 



13. A black and white larva, not unlike that of Gelechia 

 rufescens, found by Mr. E. Shepherd, near Dartford, last 

 July, by sweeping ; unfortunately it soon died, without our 

 discovering on what plant it had fed. 



14. A larva found by Mr. Harding, last July, feeding in 

 the stems and roots of Eryngium, maritimum. 



15. A larva found by Mr. Scott, in the berries of the 

 mountain ash ; the larva when full fed quits the berry, and 

 forms an open net-work cocoon, within which it forms a 

 close white cocoon. 



16. A Nepticula larva, found by Mr. Scott, making 

 blotches in the leaves of Lotus corniculatus. 



17. A Nepticula larva, in alder leaves, found near Becken- 

 ham by Mr. Douglas and myself, and near Darlington by 

 Mr. Law ; the larva resembles that of N. micr other iella, 

 the cocoon that of N. Salicis.
