88 CALOSOMA SYCOPHANTA. 



outside were thoroughly examined. It was found that the general direction of dis- 

 tribution had been toward the north and west, and territory shaped like an onion 

 embracing the northern part of the town of Wellesley and the southern part of the 

 town of Weston, and extending to a point beyond the Weston railroad station, showed 

 marked evidences of the presence of this insect. 



Wenham. — On June 27, 1908, 6 male and 6 female Calosoma beetles and 75 larvae 

 were liberated in badly infested woodland off Cherry Street. In 1909 this colony was 

 examined and beetles and larvae were found. Late fall examinations showed that 

 they had dispersed over a relatively small area. In 1910 the entire western end of 

 the town was examined, and beetles were found over an area of about one-half 

 square mile. 



July 14, 1909, 43 male and 30 female Calosoma beetles and 100 of their larvae were 

 liberated off Grapevine Road. The territory was examined in 1910, and beetles and 

 larvae were found outside the colony. Beetles and larvae were also found in the towns 

 of Hamilton and Manchester at a distance of one-half mile or more from where this 

 colony was liberated. 



Westford. — On June 24, 1910, 100 Calosoma larvae were liberated in woodland in 

 the northern part of the town, and on June 28 100 more larvae were added to the colony. 



Weston. — On June 24, 1909, 100 Calosoma larvae were liberated in woodland near 

 the railroad station, and on June 26 100 more larvae were added to the colony. Exam- 

 inations were made several times during the summer of 1910. No Calosoma larvae or 

 molted skins were found in the colony, but several were secured in the area surround- 

 ing it. In the southern part of the town the beetles have become well established, 

 having spread from the colony at Wellesley. 



West Newbury. — On July 8, 1910, 200 Calosoma larvae were liberated in woodland 

 near the top of Pipe Stave Hill. 



Westicood. — On July 9, 1910, 200 Calosoma larvae were liberated in badly infested 

 woodland. 



Weymouth. — On July 19, 1909, 200 Calosoma larvae were liberated in woodland off 

 Commercial Street, Weymouth. The colony was visited several times in 1910, and 

 on July 6 a beetle and 33 larvae were found. Later in the season molted skins were 

 found to be very abundant in this colony. 



Wilmington. — On June 25, 1910, 100 Calosoma larvae were liberated in woodland 

 about one-half mile from the railroad station. June 30, 100 more larvae were added 

 to this colony. In 1910 beetles were found in the southern part of the town that had 

 spread from a colony planted at North Woburn in 1907. 



Winchester. — On May 8, 1906, Mr. Titus liberated 41 beetles in wood and brush land 

 off High Street. During the winter most of the woodland was cut off, and although 

 careful examinations were made during the summers of 1907, 1908, and 1909 no Calo- 

 soma beetles or larvae were found in the center of the colony, but in 1910 molted skins 

 were found about one half mile north of where the liberation was made. 



Woburn. — On July 31, 1907, 23 male and 24 female beetles were liberated in the 

 piece of woodland which had been partially stripped by gipsy moth caterpillars near 

 North Woburn. On August 2, 25 pairs of beetles were added to this colony. Larvae 

 were found during the summer of 1908, and in 1909 a number of beetles was discovered 

 in the colony and molted skins of the larvae were found a mile distant. In 1910 the 

 colony had spread over a much larger area, extending throughout the northern part 

 of Woburn and into the towns of Wilmington and Burlington. 



COLONIES OF CALOSOMA LIBERATED IN MAINE. 



July 22, 1908, 100 Calosoma larvae were snipped by express to 

 Capt. E. E. Philbrook, Portland, Me. They were packed separately 

 in glass tubes with earth and were liberated by him in Kittery and
