they remain until they 'hatch the following spring. They are 

 exceedingly abundant the present season, on one small wild 

 cherry tree at Orono several dozen of these egg masses were 

 seen upon a single twig. 



Parasitic flies, Tachina mcUa, were bred from a number of 

 the larvae of both species taken in the vicinity of Orono this 

 summer. Descriptive circulars giving remedial measures -for 

 these two species are issued by the Maine Agricultural Experi- 

 ment Station. 



Dioryctria abietella and Hnarmonia youngana. 



In Insect Notes for 1911 (p. 233) mention was made of 

 injury to red spruce cones by insects. Among the insects 

 found in the cones were the larvae of 2 species of Tineid moths 

 which were later reared and proved to be the above mentioned 

 species. Lots 1303, 1386 Sub. 6.

"Fore wings dull ochreous or whitish tinted with ochreous. Near 

 the middle of the costa is a semi-oval blackish-brown spot containing 

 blackish dots, and sometimes a whitish spot on the costa. Along the 

 interior edge of this costal spot are a few tuf^, and near the base of 

 the fold of the wing is a single black one. The costa near the base is 

 slightly marked with blackish and the apical portion of the wing is 

 cloiided with reddish-ochreous-reddish. Hind wings shining, rather 

 dark gray." (Clemens). 



This common European species which is also found in east- 

 ern United States, has been rather abundant in the vicinity of 

 Orono for several seasons. The larva constructs a loose tube 

 of silk within the rolled up edge of a gray birch leaf similar to 

 that shown in figure 180 of Packard's Forest Insects (p. 507). 

 In the leaf axils of the tree upon which the larvae were found, 

 occurred curious little tubular nests each containing a larva very 

 similar if not identical with the above mentioned species. These 

 tubes are constructed of silk and debris and extend down into 

 the twig which is somewhat swelled at this point (fig. 482).
