296 THE CANADIAN ENTOMOLOGIST 



Sphingidce at Sugar. While collecting on St. Therese Island, 

 on the Richelieu River, from July 16th to 19th last, several 

 species of hawk moths visited the sugared patches, not resting, 

 but hovering as they do over flowers. Those taken proved to be 

 6 Sphinx kalmice, 1 Ampelophaga cheer ilus, 2 Ceratomia amyntor.

Notes on the Eggs of Macronoctna onusta Grote. 



A female of this moth was picked up from a window sill in 

 the business part of Montreal on September 22nd, and boxed for 

 eggs after being fed on sugar and water. Next morning a little 

 cluster of greenish eggs was on one side of the box but evidently 

 the moth did not like the conditions as she was wandering about, 

 poking her extended ovipositor into all parts of the box and the 

 11 eggs laid were not deposited in an orderly manner, some being 

 flat, some on their edges others on top of one another. 



The moth was transferred to a breeding cage with a supply of 

 leaves of Iris germanica from the garden, and at once began 

 climbing up and down the leaves. She soon selected a leaf with a 

 long crack at the base. Into this crack an egg was placed and 

 others were laid alongside of it in a row, the moth remaining in one 

 position merely moving her body. Other eggs were laid during 

 the day between the edges of the leaves where they overlap and 

 this is probably where most are placed in nature to pass the 

 winter. 



When laid the. egg is pale greenish but in a few days turns 

 purplish. It is very much flattened on top and bottom and may- 

 be likened in shape to a vest button. The width is .6mm. and 

 height .27mm., rounded at the edges. The ribs are shallow and 

 show most on the sides. Hatched May 27-29. 



Mr. Henry Bird tells me the larva? will feed on Gemmingia 

 chinensis as well as on the various species of Iris.
