Some fine specimens were secured of the different kinds of American 

 silk woi-ras. Actlas luna, the swallow-tailed luna moth was 

 particularly abundant both in the larval and perfect states, 

 as also was Telea Polyphemus. Platysamia Cecropia and Callosamia 

 Promethea occurred but not so commonly. The cocoons of the last 

 two, however, are not uncommon on our city shade trees ancl in gardens: 

 P. Cecropia chiefly on apple and maple trees, and C. Promethea 

 almost entirely on lilac {Syringa vulgaris). All of these moths are 

 preyed upon in their preparatory stages by bii'ds who pierce the 

 tough cocoons with their bills, and extract the juicy pupse. They are 

 also preyed upon in the larval state by parasitic Hymenoptera. 



The larvfe of ^J*^<l('jit.(( alblfntns were particularly abundant on 

 maple trees in September and October. Several species of Lepidoptera 

 have been reared from the larval stage during the past season; among the 

 most interesting were Darapsa versicolor, from larvae found on 

 Nes(ea verticil lata. Other larvse foimd on Cephalanthus occidentalis, 

 but not brought to maturity were referred to this species. Sjihinx 

 drupiferarum, from plum trees; Sphinx gordius, from apple trees; 

 Sphinx kalmioi, from a pupa found beneath drift wood on Kettle Island 

 by Mr. Harrington, on 19th May. This is particularly interesting as 

 it must have been submerged for some weeks during the spring 

 freshets. 



Smerinthus exccecatus. A pair of these handsome moths was taken 

 in coitu on the trunk of a white poplar in June. From these about 20 

 eggs were saved which began to hatch out on the 15th June. The first 

 caterpillar was ready to pupate, and buried on 9th July. Lust cater- 

 pillar buried on 19th July. 



CallimorjiJia militaris. The larvee of this moth were found very 

 abundantly on wild gooseberry and maple in the month of June. Some 

 larvae were collected which pupated on IStli June, and produced the 

 moths on 7th July. The moths were in great abundance, especially in 

 Beech wood. 



The Hickory Tussock moths, frotp larvae collected at Hull on 

 Carya amora. 



A single specimen of the rare Pldtycpriirafiircilld, Pack, was bi'ed 

 from a larva taken on Pinus strohas at Stewarton in September, 1882. 

 It spun up on 27th September, 1882, and emerged on 3rd June, 1883.
