EuREMA LISA IN New HAMPSHIRE. — I liavc to rccord the capture of a male 

 of this species at Alstead, N. H., Aug. 27, 1904. It was flying in upland meadow 

 country at an altitude of about iioo feet, and five and a half miles from the Con- 

 necticut River. The specimen is fresh and uninjured. This appears to be the 

 first recorded occurrence of the species in the western portion of the .state. Previ- 

 ous records are almost strictly confined to the towns near the seacoast, though one 

 is from the Merrimac valley. — James A. Field.
