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 Scirpus lacustris . 
12. A Gelechia larva, found by Mr. Scott early in May, 
mining the leaves of Av'ctostajriiylos 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 cornicidatus . 
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. microtherieltot 
the cocoon that of N. Salicis.
