THIRTIETH KEPORT ON THE STATE MUSEUM. Q16] 



also of another extremly rare species (previous to 1876), that 

 instead of extracting from it, I present it in full : 



"In accordance with your suggestion that Brephos infans 

 might be found at Center, on the 3d of April last [1876], I 

 took the early train for that place. From 7. 30 A. M. to 

 12 M., I searched through the white birch swamps without 

 meeting with one, but on emerging in a clearing on the 

 west of the timber, I was at once brought in view of a half 

 dozen or more, sailing around, at a height of from ten to 

 twenty feet above the ground. In striving to capture a speci- 

 men, I observed that it would manage to keep from fifty to a 

 hundred feet distant from me, except when flying swiftly by. 

 They were evidently well aware of my presence. At 1.30 p. M. 

 when moving very slowly and scanning closely the ground 

 and brush, a B. infans rose from an open spot surrounded 

 by some newly cut birches. To my great delight, I captured 

 it. It proved to be a fresh and perfect specimen taken, 

 perhaps, in its first flight. Although they continued to fly 

 for some time afterward; I failed to secure another. 



April 17th, I again visited Center, but searched in vain for 

 more of the infans ; not a single example was to be seen. 

 The day was colder, with more wind and but little sunshine. 

 As the weather became more unfavorable, I left the birches 

 and devoted the remainder of the day to examining the fences 

 along the railroad, and was well rewarded by the capture of 

 three examples of the rare Xylina fagina. 



April 20th, visited the locality for the third time. At 

 1 P. M., I captured my second infans this time resting on a 

 small white birch the wind blowing freshly toward me, 

 with the sun bright and warm. I observed at least a dozen 

 others, but did not succeed in taking another, although the 

 chase was perseveringly continued for several hours. I 

 repeatedly saw them alighting on small birch trees, but the 

 moment a movement was made toward them, although at a 

 distance of a hundred feet, it was noticed, and the moth at 

 once took wing again. Later in the afternoon, the fine weather 

 changed to cold and blustering, with snow, and as not a 

 single infans was to be seen, I went in search of Xylina 

 fagina. My examination of the fences was rewarded by 

 the capture of nine specimens of the species including 

 those previously taken, twelve in all. Of these, ten were
