I have two examples of the European variet}' larkana in ray ^col- 

 lection, but have never seen anything like them taken in this country, 

 nor have I heard that any one here has bred T. ocellana larva or any 

 variety of it from larch. 



Tascheuberg, in his work on Entomology for gardeners, published 

 in Bremen in 1874, page 306, says that this species is very abundant 

 everywhere, on the wing from June to August, and further says the 

 caterpillar has sixteen feet, is reddish brown with the head blackish, 

 in early spring upon the buds of different kinds of deciduous trees, 

 and also upon apple and pear trees. In his further account he follows 

 the statement of Schmidberger in Kollar's Insects, given above, and 

 adds a list of five different species of Hymenopterous parasites that 

 prey upon it. 



The first account given of it in this country, so far as I can learn, 

 was that by Harris in his Insects Injurious to Vegetation, First Edi- 

 tion, page 349, (1841), where he describes it under the name of 

 Penthina oculana^ but he does not give the early stages. 



In 1860, Clemens describes this species in the Proceedings of the 

 Philadelphia Academy of Natural Sciences, page 357, under the 

 name Hedya Pyrifoliana. His description of the moth and also of 

 the larva is very good, and he says " it inhabits the pear and plum 

 trees." 



Since that time many persons have written about it more or less 

 fully, but nothing new has been given on its habits, so far as I have 

 seen, and it has generally been supposed to pass the winter in the 

 egg state. Mr. James Fletcher, in his Report for 1885 as Entomo- 

 logist to tlie Department of Agriculture of Canada, page 24, writes, 

 "I do not know for certain the life history of this little moth, but 

 believe it passes the winter as a larva on the branches of apple trees, 

 protected by a covering of silk." 



For some years past I have observed the habits of this insect, and 

 have been able to carry it through its transformations. The moths 

 emerge between the last of June and the middle of July, though 

 belated specimens are sometimes taken on the wing as late as the 

 middle of August, and one was taken at this place August 25, 1889. 



The fore wings expand about three-fifths of an inch. The head, 

 thorax, and basal third of the fore wings, and also the outer edge and 

 fringe are dark ash gray, the middle of the fore wings is cream white, 

 marked more or less with costal streaks of gray, and in some speci- 

 mens this part is ashy gray, but little lighter than the base. Just
