REPORTS OF OBSERVATIONS AND EXPERIMENTS. 55 



long, slender, oval cocoon covered with pellets of excrement, within 

 which it changes to a chrysalis, the cocoon being situated under and 

 among the dead, reddish leaves. The larvae were observed July 1, and 

 the moth appeared the following spring. 



The Four teen- flapped Geometrid. — Several caterpillars of this species 

 from which I bred moths like Aplodes coniferaria occurred on witch 

 hazel, Hamamelis virginica, living among the tawny, yellowish-brown 

 leaflets of the ends of the shoots, September 8, at Brunswick, Me. Its 

 shape, markings, and color are such as to assimilate it to the peculiar 

 small yellowish leaflets at the end of the flower-twigs, and to enable it 

 to easily avoid the attacks of birds. It is an excellent example of pro- 

 tective mimicry. It changed to a chrysalis in a thin cocoon, and the 

 moth appeared in the breeding cage May 10 of the following year. It 

 probably lays its eggs in June on the opening buds or leaves. 



It is probable that my Aptlodes coniferaria is but a small form of A. 

 mimosaria, 



Xotes on Lepidopterons Larvae attacking Forest Trees. — From the chest- 

 nut I have reared Acronycta hamamelis Guen. It spun a thin but reg- 

 ular cocoon, and changed to a pupa October 7. Also from the yellow 

 birch, the pupa occurring September 15-20, Acronycta ovata Grote. 

 Acronycta grisea Walk, was bred from the willow and poplar. 



On the tupelo at Providence 1 found, September 28, the larva of 

 Catocala elonymplia Hbn. The caterpillar is pale gray, resembling in 

 markings and color a piece of the twig of this tree. It has no very 

 distinctive markings or prominent warts or humps. - It spun a thin 

 white cocoon and pupated October 4, and the moth emerged in the 

 breeding box on May 15 ensuing. 



From the choke cherry I have had Eutrapcla transversata Dr.. the 

 moth appearing August 24. 



From the willow I have reared at Brunswick, Me.. Boarmia crepus- 

 cidaria, the moth appearing August 30, the pupa having been found 

 August 8. 



From the chestnut at Brunswick, Me., I took, August 23, a pupa of 

 Acidalia insularia Guen., which disclosed the moth on the 27th of 

 the same month. I also collected from a maple, September •'». at Brans- 

 wick, Me., the pupa of an Eupiihecia near luteata in the shape of its 

 wings and markings, but yet apparently distinct. 



The larva* of Deilinia erytheinaria occurred at Brunswick, Me., not 

 uncommonly on the willow and poplar, the moth appearing August 6. 



Hypena. scabra Ilbn. was bred from the poplar, the moth appearing 

 September 5. 



The following Tortricids were reared: 



The pupa of Teras ferrugana Schiff. was found on a leaf of Betula 

 populifolia September 20, the moth appearing October 2. 



Cenopis rcticulatana Clem. The larva of this leaf-rollor, which is 

 recorded by Miss Murtfeldt (Fernald's Catalogue of described Tortri-
