84 CALOSOMA SYCOPHANTA. 



Maiden. — On May 8, 1906, Mr. Titus liberated 40 specimens of Calosoma sycophanta in 

 badly infested woodland in Maiden near the Saugus-Melrose line. During June, on 

 visiting the colony, he was able to find 2 beetles. This colony was examined in 1907, 

 but no trace of the Calosoma beetles or larvse was found, and although several exam- 

 inations were made the next summer nothing was found until July 16. On that date 

 6 full-grown Calosoma larvae and about 25 molted skins were collected, some of them 

 being taken 100 feet from the point where the original liberation was made. In 1909, 

 Calosoma beetles and larvse were abundant in this colony and in the fall a careful 

 examination was made of the surrounding territory. It was found that the insect had 

 spread over a section of Maiden known as the Maplewood district and as far south as 

 the Linden station. The beetles were also found over a considerable area in the 

 southeastern part of Melrose, and in Saugus in the vicinty of Cliftondale. Some speci- 

 mens were found in a section of Revere not far from the center of the colony, known as 

 Franklin Park. In 1910 examinations showed that this colony had spread over prac- 

 tically the whole northern half of the city of Maiden and into the adjoining towns 

 and cities. 



. Manchester. — On July 27, 1909, 150 Calosoma larvse were liberated in woodland on 

 School Street, about one-half mile from the Essex town line. July 24, 200 Calosoma 

 larvae were liberated in a badly infested area off School Street, one-half mile farther 

 north. Examinations of these colonies made in 1910 showed that in the latter a few 

 beetles were present, but none was found in the first colony. Infestation by the 

 gipsy moth was less severe than the previous year, as a large number of the moth cater- 

 pillars died from disease. 



June 7, 1909, 39 male and 34 female Calosoma beetles were liberated off Crooked 

 Lane, in Manchester. July 10, 300 beetle larvae were liberated north of the area pre- 

 viously mentioned and not far from the Wenham line. Examinations made during 

 the summer of 1910 failed to indicate the presence of the beetles near the point where 

 the adult colony was liberated. Molted skins were found, however, near the larval 

 colony; some were in the town of Manchester, others in Hamilton, and still more in 

 Wenham. It is probable that some of these beetles spread from the colony located in 

 the eastern part of Wenham, which will be mentioned later. 



Marblehead. — On July 9, 1908, 100 larvae of sycophanta were liberated in Marblehead 

 about one-half mile east of the Forest River station. On July 15 of the same year 100 

 more larvse were added to this same colony. Plenty of gipsy moth caterpillars were 

 present and the Calosoma colony appeared to be in a flourishing condition when it was 

 examined about a week later. During the summer of 1909 several visits were made to 

 the colony, but no Calosoma beetles or larvse were found . On June 30, 1910, the owner 

 of the property said that he had seen two ' ' green beetles ' ' in the woodland earlier in the 

 season, which were undoubtedly specimens of Calosoma sycophanta. Later in the sum- 

 mer molted skins were found near the Forest River station. Some beetles evidently 

 had survived in this colony, but many had either migrated to other places or else con- 

 ditions were not as favorable as might be wished for the rapid increase of the species. 



Marsh field .—On June 30, 1910, 200 Calosoma larvse were liberated in infested wood- 

 land near Marshfield Center. 



Maynard.— On July 25, 1910, 200 Calosoma larvse were liberated in badly infested 

 woodland. Only a small number of gipsy moth caterpillars was present, but pupse 

 were more abundant. 



Med field. — On July 2, 1910, 50 male and 50 female Calosoma beetles were liberated in 

 infested woodland in Rocky Woods. 



Medford. — No colonies of Calosoma beetles have been liberated in this town, but dur- 

 ing the summer of 1910 indications of the presence of the beetles have been found 

 throughout the northern part of the city. 



Melrose. — On June 25, 1909, 100 Calosoma larvse were liberated in the northeastern 

 part of the city not far from the Saugus-Wakefield line. June 30, 100 larvse were added
