COLONIES LIBERATED IN MASSACHUSETTS. 85 



to this colouy. Practically every section of this city was examined in 19i^and beetles 

 were found in small numbers throughout the entire area. It is j)robable that only a 

 few of these came from this colony. Large numbers must have migrated from the 

 colonies in Saugus and Maiden. In the northeast section of the Melrose Highlands 

 district the beetles were quite common in the woodland during the sununer, and it 

 was usually possible to lind one or more of the beetles or larvie at work if careful search 

 was made. 



Merrimac— On July J I, 1910, 200 ('alosonia larvae were liberated north of Main 

 Street, in Nichols Woods. 



Methiten. — On July 6, 1910, 200 Calosoma larvae were liberated in infested woodland 

 in the eastern part of the town not far from the Haverhill line. 



Middleton. — On June 23, 1910, 50 male and 50 female Calosoma beetles, which had 

 been received from Europe two days previous, were liberated in badly infested wood- 

 land off East Street. 



Milton-Qiiincy. — On July 6, 1909, 200 Calosoma larvae were liberated in infested 

 woodland near Shawmut Spring in Cunningham Park. This colony was visited only 

 once during the summer of 1910, and no beetles or larvae were found. At the time of 

 the examiuat ion many of the gi psy moth caterpillars were dying as the result of spraying 

 or from disease. 



Natick-Weston. — On July 22, 1910, 200 Calosoma larvae were liberated in badly 

 infested woodland on South Avenue near the Natick-Weston line. There were many 

 gipsy moth egg clusters and some moths present, but only a few gipsy moth pupae and 

 caterpillars. 



Newbury. — On July 8, 1910, 42 male and 46 female Calosoma beetles, which had 

 been received from Europe two days previous, were liberated in badly infested wood- 

 land near the Byfield station. 



Neu'huryport. — July 26, 1910, 200 Calosoma larvae were liberated in woodland near 

 the West Newbury line. Some gipsy moth larvae and pupa; were ])resent, but a 

 large number of the moths had laid their eggs. 



Newton. — On July 4, 1908, 100 Calosoma larvae were liberated in woodland off 

 Newton Street, about one-fourth of a mile from the Brookline line. July 6, 1909, 1 

 female beetle and 9 larvae were found on trees in the center of this colony, and later 

 in the season when the surrounding territory was scouted a large number of gipsy 

 moth pup;e was found that had been destroyed by the beetles. June 24, 1910, an 

 examination was made and beetles found in the colony. The trees had already 

 been sprayed. Late in July the territory between this colony and the one of Ueath 

 Street, Brookline, was visited and molted skins found in different localities between 

 the places where the original liberations were made. 



June 30, 1909, 200 beetle larvie were liberated in woodland off Langley Road, 

 Newton Center, and on July 13, 200 more larvae were placed in the sajne woods about 

 one-half mile from the original colouy. The territory where these liberations were 

 made was examined several times during the summer of 1910, and both beetles and 

 larvae were found. 



North Andover. — On June 16, 1910, 50 male and 50 female beetles which emerged 

 from hibernation at the laboratory were liberated in badly infested woodland off 

 Osgood Street. 



North Reading. — On July 6, 1910, 200 Calosoma larvie were liberated in woodland 

 about one-half mile from the State road. 



Peabody. — On August 28, 1907, 25 male and 25 female Calosoma beetles tliat were 

 received from Europe in August were liberated in wooded area which was badly 

 infested. All the gipsy moth adults had emerged at this time, and but few cater- 

 pillars of any kind were present to serve as food for the Calosoma beetles. Several 

 examinations were made during the summer of 1908, and on July 8 a full-grown larva 

 of C. sycophanta was found under burlap. In 1909 several beetles were found in the
