8th June till the middle of August, If not looked to in the 

 early stages is very destructive to apricot and pear trees. 



Batodes angustioraua. — I have reared this insect from yew, 

 the leaves of which it spins together ; I have also found the 

 larva comfortably rolled up in the centre of the stone of the last 

 year's yew-berry. Those I reared appeared in May, but I take 

 the perfect insect also in August. 



Ptycholovia lecheana. — Not common. Appears among oak 

 trees here from June till August. 



Fai'dia tripwictana. — Abundant among rose-bushes in the 

 garden, and to be met with in the June evenings about hedge- 

 rows in which the dog-rose grows. 



Lithographia cinerana. — I have collected many of this form from 

 poplar, and I have also collected a large number of the form — 



L. nisei/a, from sallow. I have also bred the cinera?ia form 

 from poplar, and I must confess I strongly incline to think they 

 are different insects, as I have never taken or bred from poplar 

 the richly marked insect which is attached to sallow. The basal 

 patch is also almost always strongly defined and filled up with 

 colour to the very base of the wing in nisella, whereas in cifie- 

 raiia it seldom if ever is so. Here, also, the manner of the in- 

 sect is quite different. The poplar species, when beat off, almost 

 invariably returns to the trunk of the tree or darts off to some 

 neighbouring trunk. The sallow form flies away, sometimes at 

 some elevation, and requires a sharp net or pursuit to capture. 

 I have, however, submitted a good many specimens to IMr Bar- 

 rett, and he inclines to the opinion that they are identical. 



L. penkleriaiia. — Common among alder and hazel in July. 

 Varies considerably, some specimens being brightly and de- 

 cidedly marked, others almost unicolorous. 



Phlceodes teti-aquet7-ana. — Common among birch in INIay, prin- 

 cipally over 400 feet. I have one specimen in which the ground 

 colour is almost white and the darker markings of a pale slate 

 colour. 



Pcedisca soi'didana. — Not common. My specimens were beat 

 out of alder at a low elevation. 



P. solandriana. — Common at all altitudes. I^Iy specimens 

 vary from rich red brown to pale ochreous or slate colour, most 

 having a rich white blotch on the inner margin, others with the 

 blotch much the same shade as the ground colour, but I do not 

 remember ever having seen a specimen v>ath the large dark brown 

 blotch on the inner margin as described by Mr Stainton, or like
