INSECT NOTES. 265 



just hatched on wild cherry at Orono June 12 was likewise bred 

 on apple leaves and the moths emerged August 5-12. As is 

 often the case with an insect which has for several seasons been 

 particularly numerous, the cherry-tree tortrix has been this sea- 

 son attacked by various insect parasites. 



Of the hymenopterous parasites, Pimpla conquisitor was 

 taken at the ugly nest of this tortrix at Portland, July 23. 

 Exochiis albifrons Cr. were reared from ugly nests receivea 

 from Otisfield, Maine. Labronchus* sp. were reared from ugly 

 nests from Otisfield, Waldoboro and Orono. Macrocentms* 

 sp. were reared from nests from Waldoboro and Orono. A 

 dipterous parasite, Dichcetoneura leucoptera Johnson, emerged 

 in great numbers from ugly nests from various localities. 



One of the solitary wasps, Odynerus sp., was observed on 

 the nest of this tortrix at Kennebunkport July 24. It had cap- 

 tured a full grown larva and with its jaws grasping the cater- 

 pillar just back of the head, was preparing to take flight. The 

 larva was limp and helpless. 



Archips fervidana Clem., the oak ugly nest, was reported this 

 year as last from Mt. Desert Island. September 8 a corre- 

 spondent from Southwest Harbor stated that from one to 

 several of these nests were in every oak and that the caterpillars 

 were denuding the oak groves rapidly. Some of the same 

 species of hymenopterous parasites which were present with 

 A. cerasivorana emerged from Mt. Desert nests of fervidana. 

 Dichatoneura leucoptera Johnson and one other dipterous para- 

 site were also bred from fervidana. 



Orchard Insects in Maine. 



There is probably no reason so far as insects are concerned 

 why apple raising should not be as profitably carried on in 

 Maine as in other parts of- the country. The conditions are, 

 however, in many places far more promising at present for 

 the production of insects than apples. Almost unbroken lines 

 of neglected and therefore dangerous apple trees stretch for 

 miles along the roadsides, scattering ungathered windfalls as

 20 other insects appearing in this bulletin, which were not named in the
