COLONIES LIBEEATED IN MASSACHUSETTS. 83 



summer of 1910 with the same result. Early in the season fire ran through the woods 

 and burned over the area where the liberation had been made . 



July 16, 1909, 200 Calosoma larvae were liberated on the east side of the town, in 

 woodland, off Paint Mine Road. The colony was examined several times during the 

 summer of 1910, but no beetles were found. On October 4 several molted skins were 

 found 100 yards outside of the planting, and also a large number of gipsy moth pupae 

 that had been eaten by the Calosoma larvae. 



Lincoln. — On July 18, 1908, 100 Calosoma larvae were liberated in infested woodland 

 about 1 mile northwest of the railroad station. The colony was examined several 

 times during 1909, but few beetle larvae were found. Gipsy moth caterpillars were 

 very abundant in a part of this colony, and some of the trees were stripped, and this 

 caused the owners to have a portion of the area sprayed. The colony was inspected 

 several times in the summer of 1910 and a few Calosoma beetles were found. In the 

 fall a careful examination showed that the beetles had spread about three-fourths of a 

 mile north and one-half a mile east of the planting. A number of molted larval skins 

 was found throughout this area. 



Littleton.- — On July 15, 1910, 200 Calosoma larvae were liberated in woodland about 

 one-fourth of a mile from the railroad station. Gipsy moth caterpillars were com- 

 mon, but none of the trees had been stripped . 



Lowell. — On July 18, 1910, 200 Calosoma larvae were liberated in woodland near the 

 Lowell General Hospital. 



Lynn. — No beetle colonies have been planted in this city, and up to and including 

 the year 1909 no evidence of the presence of this insect could be found, although 

 several days were spent in making careful examinations in various sections of the 

 Lynn woods. It was believed that the insects would make their first appearance in 

 that part of the city, owing to the fact that several colonies had been liberated in 

 Saugus and Lynnfield. In the summer of 1910, in several localities which had been 

 visited the previous summer, beetles and larvae were found. Later in the summer 

 examinations were conducted for molted skins, and in some parts of the Lynn woods 

 they were found abundantly. Molted skins were also found throughout the northern 

 part of the city and in the residential section nearest the woods. 



Lynnfield. — On July 7, 1906, 100 specimens of Calosoma sycophanta and 20 specimens 

 of Calosoma inquisitor were placed by Messrs. Titus and Mosher in woodland near 

 Broadway. This colony was visited several times during the summer of 1907, but no 

 beetles or larvae were found. In 1908 examinations on July 2 and July 8 resulted in 

 the discovery of several larvae in the center of the colony. Several visits were made in 

 1909 and a considerable number of beetles and larvae was found during June and early 

 July. Later examinations were made and it was found that the Calosoma had spread 

 over a large area in the eastern part of the town. It had also spread north and west so 

 that this colony had fused with another, which will now be mentioned. June 20, 1906, 

 Mr. Titus liberated 118 beetles in a pine grove which was nearly surrounded by hard- 

 wood growth. The trees were badly infested by gipsy moth caterpillars, and although 

 several examinations were made later in the season no Calosoma beetles or larvae were 

 found. July 31, 1907, a single larva was found by Mr. Collins, and on the same date 50 

 pairs of beetles were liberated a short distance from the point where the previous 

 planting had been made. Several examinations were made during the summer of 

 1908, and 2 live Calosoma beetles were found on July 23. In 1909 the Calosoma beetles 

 were more numerous, and the examination of the surrounding territory showed that 

 this colony had fused with the one in Lynnfield, already mentioned, and specimens 

 were also found west of the colony in the town of Saugus . Subsequent scouting showed 

 that two colonies in Saugus, which are treated under that town, had spread to such an 

 extent that they had joined with the Lynnfield colonies. In 1910 examinations were 

 made late in the season and traces of the beetles were found throughout the southern 

 part of the town as well as in adjoining towns, which will be mentioned later.
