be much safer to exclude seedling pines, particularly as there is grave 

 danger of importing the very destructive pine blister rust. 



Dichromeris marginellus Fabr. The European juniper webworm, 

 kindh" identified through the courtesy of Doctor Howard and Mr. 

 Busck, discussed below, appears to have become well established in 

 New York State, since abundant material M'as received in February 

 last from Mr. S. 6. Harris, Tarrytown, N. Y., and later throug'h the 

 State Department of Agriculture from L. D. Rhind of Plandome, 

 L. I. The light brown larvae some 6 mm. long were observed upon the 

 junipers in early ]March. They form an irregular web and appear 

 to live to a large extent, at least, upon the dead or nearly dried 

 juniper needles. At least a number of moths were reared the last 

 of May and in early June from nearly dried juniper twigs collected 

 the preceding March. This alone suggests that the larvi^e can thrive 

 to a considerable extent upon rather dry vegetable matter. 



Larva. Length 6 mm. Head dark reddish brown, sparsely clothed 

 with set«. Antennte yellowdsh brown, short; thoracic shield broad, 

 a variable dark brown, setose. Segments distinct. Body light brown, 

 longitudinally striped as follows : Median stripe reddish brown, sub- 

 median stripes whitish, sublateral stripes dark brown, the lateral 

 light reddish brown; all somewhat broken. Body seta? with a length 

 about half the diameter of the body, light brown ; tubercles small, 

 brown. Thoracic legs dark brown, prolegs yellowish white, light 

 brown apically. Ventral plate reddish brown, the middle paler, the 

 posterior margin dark brown, sparsely setose. 



Adult. Length 7 mm. AVing spread 15 mm. This beautiful moth 

 is most easily recognized by the reddish brown forewings bordered 

 anteriorly and posteriorly with a broad, silvery stripe, the latter 

 tapering slightly and disappearing near the tip of the wing. The 

 rather long palps are reddish basally, grayish distalh*, creamy white 

 dorsally and near the middle with a slender pencil nearly as long 

 as the palpi, extending dorsally. The head and the anterior portion of 

 the thorax mesially, is thickly clothed with long, creamy white scales. 



Hyponomeuta malineUa Zell. Apple seedlings with the web nests 

 of the above named species were found during June by agents of the 

 State Department of Agriculture, on blocks of recently imported 

 trees here and there in the state. This species and more especially 

 the allied H. padella Linn, were noticed earlier in some detail by 

 Professor Parrott^ and the record given below is of interest largely 

 since it records the continued introduction of members of tliis genus.
