Inareolata punctoria R oman .— A single specimen of this ichneumonia 
parasite was recovered near the Erie Township, Monroe County, Mich., 
colony site, at a point where it has been taken for 5 consecutive years, 
the East, however, this parasite was generally dispersed m the vicinity of 
Boston, in southeastern Massachusetts, and around the colony site near 
Hartford, Conn. It was found to he present over an area of 524 square miles 
in the Boston area, with several collections from this area showing parasi- 
tization of over 10 percent and one of 17»3 percent. I_. punctoria was 
present throughout the area within 12 miles of Taunton, Mass., covering an 
area of 226 square miles, with parasitization as high as 10 percent (see 
map 2). 
In the East Hartford, Conn., area this parasite has increased very 
rapidly in abundance and in the extent of its distribution since 193^* Re- 
leased at this point in 1934, at the close of^L937 it covered about 15 
square miles and was recovered from 19 of the 26 collections made. One 
collection yielded 23 parasites, or 24.5-percent parasitization. This 
larval parasite was recovered from one sectiorf at Atlantic, IT. J.» but was 
not recovered from the Lee, Va. t district. At*the close of 1937 i.* punctoria 
was present in an area totaling not less than 75^ square miles in the in- 
fested area in the Eastern States. 
Macroccntrus gifuensis Ashm .— This species was not recovered from the 
Malden, Mass., area but its firm establishment and. continued maintenance 
were again confirmed for the Taunton, Mass., area. In the latter area 
M. gifuensis was reared from 15 separate collections obtained in a district 
extending over 45 miles from the vicinity of Tiverton, on Mount Hope Bay 
in Rhode Island, northeast as far as collections were made in the direction 
of Scituato, Mass, (see map 2). Since a number of scattered liberations of 
Macrocentrus were made in this area, its present distribution does not 
necessarily represent dispersion from any one point. However, it is probable, 
as judged by the relative abundance of the parasite in parts of the area 
from which it was recovered, that most, if not all, of its present distri- 
bution may be traced to the original release of 4l adults of the Oriental 
strain made at Bridgewater, Mass., in 1931* or 1° the release of 8,686 
adults of the same strain at the same locality in 1932. The 1932 release 
was the last liberation of the species in this locality. It was not until 
1936 that a parasitization as high as 20 percent was recorded. In the 
1937 fall collections, the highest parasitization was 33 percent. M. gifuen- 
sis had not yet been released at the other points surveyed in 1937 * 
Chelonus annul ip es Wesm. — The braconid parasite C. annulipes , which 
attacks corn borer eggs, was recorded in numbers from the Taunton, Mass. , 
area only but here it was obtained from 12 separa.te collections. The 
parasite is concentrated within an area of approximately 75 square miles 
centering at Berkley (see map 2), but was also recorded at 2 other points 
in the Taunton area, one near the town of South Wareham about 10 miles south- 
east and one near Abington, almost 15 miles no^th of the area of high concen- 
tration. In 3 collections made in the central part of the Taunton area 
parasitization by this species was 13*0, 15*2, and 24.0 percent. The only 
other point where C_. annulipes was recovered in the 1937 survey was in the 
Lee district of Virginia, where 2 specimons were taken in the immediate 
vicinity of the locations where this parasite was released in 1936 and 1937 .
