82 CALOSOMA SYCOPHANTA. 



was made in and around the colony. A few molted skins were found under burlaps, 

 and also some 100 yards east of the original planting. 



Gloucester. — On June 23, 1908, 75 Calosoma larvae were released in a moderately 

 infested woodland area about 1 mile east of the West Gloucester station. July 14, 

 100 larvae were liberated in an infested woodland area half a mile east of the West 

 Gloucester station, and on July 30, 100 more larvae were placed in the woods a short 

 distance from the point where the last-mentioned liberation was made. 



These colonies were examined in 1909. Nothing was found in the first colony, but 

 in the second, beetle larvae were observed on July 10 and 16, and later in the year a 

 considerable number of molted skins was found. 



July 20, 1909, 200 Calosoma larvae were liberated in woodland off the State R.oad in 

 Magnolia, and on July 22, 200 were placed in a badly infested wooded area near Has- 

 kell's Pond. 



In 1910 all these colonies were examined during the summer, and in the early fall 

 the surrounding region was carefully scouted for molted skins. No indications of 

 Calosoma beetles were found in or around the colony liberated 1 mile east of West 

 Gloucester station. 



In the colony liberated near the West Gloucester station a few beetles were noted 

 during that summer. Later in the season molted skins were found 1 mile south and 1 

 mile west of the center of the colony. 



Molted skins were also found in the colonies liberated near the State Road at Mag- 

 nolia and at Haskell's Pond, which indicated that these plantings had sur\dved and 

 the beetles were increasing. 



Groveland. — On July 5, 1910, 200 Calosoma larvae were liberated in an infested 

 wooded area located on a hill near the center of the town of Groveland. 



Hamilton. — On July 14, 1909, a colony containing 60 male and 44 female beetles 

 and 100 larvae was liberated in infested woodland off Farm Road. June 1, 1910, 1 

 male beetle was found in this colony. Later in the summer examination showed that 

 several molted skins were present in the colony and a few were also found 100" yards 

 distant. 



Haverhill. — On July 5, 1910, 200 Calosoma larvae were liberated in badly infested 

 woodland about 1 mile north of the Groveland Bridge. On July 6, 200 larvae were 

 released in woodland in Bradford, near the electric car line from Haverhill to Andover. 



HopHnton. — On July 7, 1910, 50 male and 50 female Calosoma beetles received from 

 Europe were liberated in infested woodland in Hopkinton. 



Hudson. — On July 7, 1910, 50 male and 50 female Calosoma beetles received from 

 Europe the previous dav were liberated in infested woodland on Priest's Hill. 



Hyde Park. — On July 19, 1910, 200 Calosoma larvae were liberated in woodland near 

 the corner of West and Austin Streets. 



Ipswich. — On July 17, 1909, 200 Calosoma larvae were released in woodland off 

 Rowley Road. July 16, 1910, a male beetle was found in this colony. Gipsy moth 

 caterpillars were very abundant, and the trees were being stripped of foliage. A 

 later examination, made on September 20, 1910, revealed the presence of a consid- 

 erable number of molted skins of the Calosoma larvae in this colony. 



Lawrence. — On July 18, 1910, 200 Calosoma larvae were liberated in woodland off 

 Beacon Street, South Lawrence. 



Lexington. — On July 3, 1908, 100 Calosoma larvae were liberated in woodland near 

 the State Road in Lexington. The trees on the opposite side of the street had been 

 entirely defoliated by the gipsy moth caterpillars, and many of those in the area 

 where the liberation was made were badly stripped. Gipsy moth caterpillars were 

 very scarce, but some moth pupae were present on the trees where the Calosoma larvae 

 had been released. The colony was examined several times during the summer of 

 1909. No trace of Calosoma beetles or their larvae could be found. Gipsy moth 

 caterpillars were rather scarce. Several examinations were also made during the
