This Mantis became established in the neighborhood of Phil- 
adelphia in the late '90's in the vicinity of large nurseries which 
imported plants from the Old World. Egg-masses from this 
colony have been distributed from time to time in the hope of 
promoting the widespread introduction in this country of this 
beautiful and useful insect. A few were placed out at Wellesley 
and a single adult was captured in the fall of the same season. 
Better luck attended their introduction into Connecticut, where 
Walden states that twenty-five masses were placed in five local- 
ities in the winter of 1904 with the result that about a dozen adults 
were seen in three of these localities the following autumn and a 
few were found the second season, showing that the insect may 
live through the winter in southern New England. It has also 
apparently been introduced a second time into Connecticut on 
plants received directly from Japan. It is, however, very doubt- 
ful whether it has become permanently established within our 
limits.

This well-known European insect has become established in 
the vicinity of Rochester, New York. The original introduction 
was probably accidental, with nursery stock. ''As this species 
often lays its egg-masses on the stems of grass it has been sug- 
gested that an egg-mass might have been in the hay which is often
