and thus preventing the distribution of small caterpillars by wind. 

 New and very powerful spraying machines have been introduced 

 capable of forcing the spra}nng liquid through a mile of l|-inch hose. 

 An abnormally severe winter caused a material reduction in the 

 infestation in many localities, and this may have also reduced the 

 increase of some of the introduced egg-parasites, though this cannot 

 be determined till later in the season. Nearly 2,000,000 specimens 

 of Schedius kuvanae, the egg- parasite of the gipsy moth, were released 

 late in September and October. In the spring of 1918 less than 

 2,000,000 specimens of Anastatus bifasciatus, a single-brooded egg- 

 parasite of the gipsy moth, were liberated, being fewer than in the 

 previous year owing to the severe winter. Compsilura concinnaUi 

 was reared from a number of native caterpillars not previously known 

 to be hosts of this parasite. Blepharipa scutellata, a Tachinid that 

 parasitises large gipsy-moth caterpillars and emerges from the pupae, 

 was more numerous in the summer of 1917 than in any other year since 

 its introduction. Apanteles melanoscelus, which has two annual 

 generations, the first of which attacks small gipsy-moth caterpillars 

 and the second nearly full-grown ones, was satisfactorily bred for 

 colonisation by a new method. Calosoma sycophanta was more 

 abundant than usual in badly infested sections. No severe infestations 

 of the brown- tail moth having been recorded, there was a corresponding 

 decrease in the abundance of its imported parasites. Attempts have 

 been made to determine the abundance of the brown-tail moth fungus 

 in the winter webs, and studies have been made of an unnamed fungous 

 disease in eggs of the gipsy-moth, and of a bacterial disease which 

 originated in Japan and attacks the gipsy-moth caterpillars in the field.
