COLONIES LIBERATED IN MASSACHUSETTS. 81 



Cohasset. — On July 12, 1909, 200 Calosoma larvae were released in badly infested 

 woodland near the Jerusalem Road, and on July 27, 200 additional larvae were liberated 

 in woodland off Forest Avenue, about one-half mile from the colony previously men- 

 tioned. During the summer of 1910 the trees near where the first planting was made 

 were badly defoliated. The colony was visited by Mr. Schaffner on July 1, but no 

 beetles or larvae were observed. Mr. Frank A. Bates, one of the agents employed by the 

 State forester, informed me that he found several specimens of this beetle during that 

 summer in this colony. 



The colony off Forest Avenue was also visited by Mr. Schaffner on July 1. No 

 beetles or larvae were found, but the trees were not defoliated so badly as in the other 

 colony. Examinations later in the season failed to reveal any traces of the beetle in 

 this colony. 



Concord. — On July 10, 1908, 25 male and 25 female beetles and 100 larvae were 

 released near Fairhaven Bay in infested woodland. Only a moderate amount of 

 wooded area was infested, and most of the caterpillars had pupated at the time the 

 liberation was made. June 28, 1909, a colony of 200 larvae was liberated in the north- 

 western part of the town in badly infested woodland off Strawberry Hill Road. July 

 2, 1909, another colony of 200 larvae was liberated near Walden Pond, in a moderately 

 infested region. July 14, 1909, 200 larvae were liberated in infested woodland off 

 Sudbury Road. 



During 1909 the Fairhaven colony was examined several times, and a few beetles and 

 molted skins were found during the season. 



Examinations made in 1910 indicate that the Fairhaven and Walden Pond colonies 

 have survived, and that the beetles have spread a considerable distance from where the 

 liberations were made. Only a few visits were made to the other two colonies, but 

 no indications were found that the beetles had been working during the season. 



Danvers. — On July 15, 1909, 300 Calosoma larvae were liberated in woodland off 

 Nichols Street, Danvers. The trees had been badly defoliated, and many of the 

 caterpillars were dying from disease. A considerable number of gipsy moth pupae 

 was present. June 21, 1910, the colony was scouted by Mr. Proctor, and 2 male beetles 

 were found. On September 17 another examination was made, and molted larval 

 skins were found 200 yards from the center of the colony. 



Dedham. — On July 9, 1910, 200 Calosoma larvae were liberated in woodland off Sandy 

 Valley Road. 



Dover. — On July 2 1910, 200 Calosoma larvae were liberated in woodland off Pleasant 

 Street, Dover. 



Dracut. — On June 24, 1910, 50 male and 50 female Calosoma beetles were liberated 

 in badly infested woodland near Lak?view Park. 



Essex. — On July 7, 1909, 149 Calosoma larvae were liberated in infested woodland 

 near Wood Drive, near Chebacco Lake. July 22, 1909, 200 Calosoma larvae were 

 liberated in woodland near a bad gipsy moth infestation off Conomo Drive. July 24, 



1909, 200 larvae were liberated in woodland off the Old Essex Road, near the town line 

 of Manchester and Essex. All of these colonies were examined during the summer of 



1910. On June 14, 2 beetles were found in the last-mentioned colony, but in the 

 others no adults or larval skins were secured. 



Framingham. — On July 16, 1910, 200 Calosoma larvae were liberated near Framing- 

 ham Junction, in infested woodland. 



Georgetown. — On July 17, 1909, 200 Calosoma larvae were liberated in woodland 

 near Baldpate station. The infestation was moderate and conditions were favorable 

 for a colony. June 16, 1910, the colony was examined, but no beetles found. The 

 woodland had been sprayed, but many gipsy moth and brown- tail moth caterpillars 

 were present. July 5 examination was made in the territory immediately outside of 

 the colony and two Calosoma larvae were found . On September 19 another examination
