78. BULLETIN OF THE BROOKLYN ENT. SOC. 



The influence of new conditions is plainly and remarkably evident in the 

 great change in the shape of the wings, and of the transparent lunules upon 

 the wings. The insect seems though the shape of the Promethea moth, 

 to be rapidly advancing towards the likeness of the Cecropia. 



I am not able to state it as an absolute fact, but casual observation 

 has led me to believe that the larva of the Cynthea does not run the meshes 

 of its silk so far from the main cocoon as formerly. As a consequence, 

 the cocoons on the Ailanthus tree are not so generally fastened to the woody 

 branch, and are more liable to fall and be destroyed.

Notes on Nemoria Chloroleucaria, 



Gue 



In July last we found a slender Geometrid larva feeding upon the 

 petals of the clustered flowers of the common oxeye daisy, Leucanthemum 

 vulgare. It had already passed its last moult and pupated not long after 

 we found it. At its full development it was 25 mm. in length by less than 

 2 mm. in diameter. The head was of a russety color and had two ear like 

 projections at the summit. There were also two similar smaller appendages 

 on the second segment of the body which were also of a russety color. 

 The body itself was dull green with" a yellowish tendency towards the back 

 which was marked with a line of purple. The legs were ten in number. 

 Before pupatation the larva made a slight cocoon drawing together leaves 

 with threads of silk. The pupatation took place July 24. The head was 

 slightly russetv, the body whitish green with black dorsal line. Before be- 

 coming an imago the eyes showed black and the body became pale dull 

 white. The length of the pupa was 8 mm. The imago a male appeared 

 August 4. The time of the pupal stage is therefore only 10 days. 



We have found the imago early in spring so the insect is undoubtedly 

 two brooded in this latitude. 



There is a brief statement concerning the larva of this insect in Pack- 

 ards Geometrid Moth page 371. Comparing these with our own observa- 

 tions we conclude there must be considerable variation in food-plant and 

 i of the larva. Mr. Goodell states his example made no cocoon but 

 olu^p.) fastened itself to the bottom of the box. It is likely that with loose 

 leaves this fastening would have been the slight cocoon of our experience.
