field, Dexter, Winterport, Readfield, Portland, Gardiner, Lis- 

 bon, Newcastle and Wiscasset, and about 15,000 cocoons dis- 

 tributed. 



A sufficient number of Meteorus versicolor were also obtained 

 to establish two colonies of this parasite which is handled in 

 a very similar manner to the Apanteles already described. As 

 soon as the work on the Apanteles and Meteorus was completed, 

 work with the Compsilura and Calosoma was taken up and con- 

 tinued until plantings of each had been made. The Compsilura 

 concinnata should prove of great economic value, as it will at- 

 tack both the gypsy and brown-tail moth with avidity and at 

 least sixteen of our native insects are known to serve as its 

 hosts. The cabbage butterfly and the tussock moth are readily 

 attacked and great good may be expected to this vicinity where 

 the tussock moth to Portland and the cabbage butterfly to Cape 

 Elizabeth have at times been considered as serious pests. Colo- 

 nies of this parasite have been liberated in the towns of Yar- 

 mouth, Gardiner, Georgetown, Waldoboro, Oxford, Baldwin 

 and Portland. Two colonies of the Calosoma beetle were estab- 

 lished, one in Portland and one in the badly infested woodlands 

 of York. We collected several hundred of the larvae of these 

 beetles and confined them in hibernating ground cages at the 

 laboratory, where they will be available for colonization in the 

 spring of 1914.
