larvae may not be met with) ; and the summer brood may be looked 

 for from the middle of June to the middle of July : but the great har- 

 vest is from the middle of September, until the trees and hedges are 

 bare. The collector has then comparatively no other game in view, 

 and the larvae are in far greater abundance than in the summer ; be- 

 sides, by keeping the pupae in a warm room, he breeds a considerable 

 number during the winter months, when he would otherwise have no 

 insects to set : and this very circumstance of his continuing to set 

 these little moths uninterruptedly throughout the winter, will give him 

 that knack and dexterity in handling them, of which we are all so 

 much in need. 



8. On what Plants is the Collector to look for the Larvae of Nepti- 

 culae? On all. Probably there are few trees or bushes on which some 

 species does not feed ; and though we can hardly expect all the low- 

 growing plants to be fed upon by species of this genus, it is only by 

 continually looking on these plants that we can hope now and then to 

 detect a new species of larva. 



9. On what Plants have the Larva of Nepticulce been found ? The 

 following is a list of those plants at present known to serve as food to 

 the larvae of Nepticulae : — 



* Apple. * Hornbeam, (2 species). 

 Beech. * Hypericum perforatum. 

 Birch. t Mountain ash. 



* Bramble. * Nut, (2 species). 



* Buckthorn, {Rhamtius ca- * Oak, (3 species). 



tharticus). * Rose, (2 species), 



t Cherry. * Sallow, 



t Clematis. * Sloe. 



* Elm, (2 species). Sorrel. 



* Geum urbanum. t Strawberry. 



* Hawthorn, (3 species). t Teucrium Scorodonia. 

 The perfect insects have been bred from the plants marked thus, *. 



On those plants marked f no larvae of Nepticulae have yet been found, 

 but the leaves that had been mined by them have been observed, and 

 I have specimens of the mined leaves, which I can show to those cu- 

 rious in such matters. 



Should any collector fall in with any larvae of Nepticulae upon any 

 plant not mentioned in the above list, I should be most thankful for 

 the information. The number of species is in all probability far from
