were collected in 1920 and 1921, and we suspected that there might be 
some connection between them. 
More larvae were collected but were at once separated so that they 
could not injure each other, and on July 24, 1923, adult beetles emerged. 
Prior to their emergence, specimens of the larvae were sent to the Bureau 
of Entomology at Washington, and identified provisionally as Anomala 
orientalis Waterhouse by Dr. A. G. Boving. The beetles reared here 
were at once recognized as the same as those which had been collected, 
namely, Anomala orientalis Waterhouse. 
The locality where the collections were made was until two years 
ago a part of a nursery which several years ago imported many shipments 
of plants from Japan, and some of the plants came in balls of earth. 
This nursery has now removed to Woodmont, nearly six miles distant, 
and dwelling houses now occupy the land formerly covered with nursery 
stock. The infested lawns are not on the nursery grounds but across the 
street and extend for one or two squares northward and somewhat 
eastward from the point where the beetles were collected in the margin of 
the nursery. 
The scouting which has been done indicates that the injured lawns are 
all in a residence section and within five or six city squares or blocks, 
but we do not know how widely this pest may have been distributed 
from the nursery, or how far the infestation may have spread beyond 
the area where injury is apparent, as a small number of grubs per square 
yard would not kill the grass, and therefore would not be noticed. 
When this insect first appeared in Hawaii some ten years ago, it was 
so destructive to sugar cane that parasites were imported from Japan in 
the hope of controlling it. One of these, a Hymenopterous parasite, 
Scolia manilae Ashm., was established in Hawaii during the years be¬ 
tween 1914 and 1915, and proved effective. From an area where in 
1917, 3,500 Anomala grubs were collected, this parasite had so thor¬ 
oughly reduced the pest by 1919, that by careful search only four grubs 
could be found. Scolia manilae is one of the parasites introduced into 
New Jersey on account of the Japanese beetle, but does not survive the 
winters. Consequently we can hope for little help from this insect, 
though there is a possibility that some of our native species of Scolia 
or Tipkia may attack the grubs. 
The beetles do not seem to fly, but keep near the ground in the stubble 
or crawl upon the stems of grass and weeds. This habit is a distinct 
advantage where control measures are attempted.
