When young, the larva is rather slender and long, white, with a 

 faint yellowish tinge, dorsal line slightly darker and very narrow 

 dorsal vessel visible, slender also. Head clear light brown, its two 

 halves oval, plates hardly visible, very faintly tinged with brown. 

 Altogether an unusually clear, white looking larva. In the middle of 

 April, when nearly full grown, three quarters of an inch long, clear, 

 shining, yellowish-white or creamy, with a quadrate pink internal 

 spot, visible through the skin of the 9th segment, head and dorsal 

 plate light brown, anal plate grey. Pupa light brown, very restless. 



Perhaps I should apologize for going so much into detail respecting 

 a larva which has repeatedly been reared before, which is described 

 and its food given by Mr. Staiuton, in the "Manual," in about ten words, 

 and which has been more particularly described by Colonel Goureau 

 in the Ann. Soc. Ent. Fr., 1S51, p. 323, but its habits are so peculiar 

 that they interested me very much. It seems reasonable to conclude 

 that the eggs are laid on the stems of the food-plant, and that the 

 young larvffi mine down them into the roots, but no trace of the place 

 of entrance is discernible. 



Finally, as an encouragement to further effort, one specimen of 

 O. ericetana actually emerged from the same pot. Its larva must have 

 fed in the same roots, there being no other plant in the pot.

DESCEIPTION OF THE LARVA OF EUP(ECILIA MACULOSANA, 

 AND ITS HABITS. 



BT JOHN H. WOOD, M.B. 



On several occasions I had found when opening the dry stems of 

 JlmhellifercB, in the winter, a larva, from which I had bred Eupoecilia 

 onaculosana. The larva alw^ays occupied a short gallery, or rather 

 chamber, in the pith, and the limited amount of frass present, as well 

 as the absence of extensive workings, showed that it must have fed up 

 elsewhere ; but where that Avas, remained a puzzle till the summer 

 of 1876. 



I was collecting Tortrices in a moist place in one of the woods 

 here, one afternoon in the month of June, and had boxed such insects 

 as F.fiiligana, S. euphorhiana, S. puncticostana, &c.,whenl saw a spe- 

 cimen of E. maculosana alight on a seed-vessel of the common blue- 

 bell {Agraphis nutans), and apparently deposit an egg. It then flew 

 to another plant, and so on to another. I was unable to follow up the 

 clue that season, but the following July, towards the end of the month,
