nigntfall on several evenings in succession | saw a group of 
six or eight males of this species spinning slowly around the © 
trunk in zigzag course, rising and falling, but never depart- 
ing more than a few inches from the bark, nor rising as high 
as the spreading branches above. By climbing a pole that leaned 
against the trunk, and swinging a net above me I was able to 
capture a few specimens. The other situation in which 1! 
found this species was in my water tent trap [see preceding 
chapter]. Here were both males and females, doubtless re- 
cently emerged from the bed of the brook; or, possibly from 
the scanty layer of moss that was exposed on some of the 
stones in the brook. This is a very different habitat from 
that reported from the European species of the genus — excre- 
ment, or decaying matter | Wahlgren. Ent. Tidskr.]. 
4 Discobola argus Say. Several times reported from 
the State, hitherto, but not encountered by me. 
5 Dicranomyia badia Walk. I collected this species 
sparingly at “ The Glen” Ithaca in May, and there are speci- 
mens in the Cornell University collection dated in June.
