hole from under the left foreleg to the mouth of the mouse." 

 The writer did not say whether the mouse was the common Mus 

 musculus or a native species. 



Phorbia fusciceps. 



The bean maggot was again reported from various parts of 

 the state doing much damage to yovmg plants. Some growers 

 reported the loss of half the plants. Injury to seed potatoes 

 was also recorded. 



Pegomyia vicina. 



Many leaves of the beets growing on the University farm at 

 Orono were found with the beet leaf miners. Some parasites 

 belonging to an undescribed species of Opius were bred from 

 this species. Lot 1392. 



Rhagoletls pomonella. 

 As in the past the apple maggot continues to be by far the 

 most serious dipterous pest in Maine. No better remedy than 

 that of the destruction of windfalls either by pasturage or by 

 gathering, advised by Professor Harvey years ago, can at pres- 

 ent be recommended. The announcement made 2 years ago 

 by Mally of South Africa that certain fruit flies related to our 

 Rhagolctis were controlled by poisoned sweetened bait has led 

 several entomologists in this country to experiment along this 

 line. The Cornell (N. Y.) and the N. H. Stations in prelimi- 

 nary notices give hopeful accounts of their experiments. Our 

 own experiments made this season upon two Talman sweet 

 apple trees, using a spray of arsenate of lead and brown sugar 

 in solution gave discouraging results. If circumstances permit 

 these experiments will be repeated upon a larger scale next 

 season, with a modification of the spray formula. 



LEPIDOPTERA. 

 Items of at least local interest are recorded of several 

 species of butterflies and moths some of which were particu- 

 larly significant in 191 1. 



Anosia plexippus. 

 Great migrating swarms of monarch butterflies were reported 

 to be passing through the southern end of Orr's Island late in 

 August and to be still flying in great numbers Sept. 15.
