Undescribed Species of Dicranoptycha 
57 
Abdominal tergites brown, segments seven and eight dark 
brown, segment nine slightly paler; remainder of hypopygium 
yellow; sternites brownish yellow. Male hypopygium with the 
outer dististyle relatively short, rather strongly curved to the 
acute tip, with about the distal half to third of the style black- 
ened; base of style with microscopic setulae that become longer, 
more conspicuous and suberect outwardly, the surface of the 
style in the blackened portion microscopically serrulate on all 
surfaces. Inner dististyle longer, fleshy, with conspicuous setae, 
the style gradually narrowed to the blunt apex. Aedeagus 
small and inconspicuous, subequal in size to one of the lateral 
processes, the latter broad at base, thence gradually decreasing 
to the narrowly obtuse apex. 
Habitat. — North-eastern United States. 
Holotype, Greenfield Mt., Franklin Co., Massachusetts, 
September 6, 1925 (G. C. Crampton). 
Paratopotypes, cf $ , August 23-September 6, 1925 (C. P' 
Alexander); paratype, U, Niagara Falls, New York, September 
6, 1911 (M. C. Duzee). 
Type in the writer’s collection. 
All of the records for D. sobrina 0. S. in my “Crane-flies 
of New York,” Part I, Cornell University Agr. Expt. Sta. Mem. 
25: 797; 1919, pertain to this new species. Material was sent to 
various collections in 1925 with the determination of D. sobrina. 
The species flies late in the season and all of those seen alive by 
the writer occurred near sluggish streams of water, usually at the 
foot of wooded hillsides. 
Dicranoptycha megaphallus sp. n, 
Male. — Length about 8 mm.; wing 9.2 mm. 
Generally similar to D. sobrina O. S., differing conspicuously 
in several features, notably the short costal fringe of the male 
and the spinulose outer dististyle of the male hypopygium. 
The head and thorax of the type are greasy and the color- 
ation is discussed in general terms only. Antennae with the 
scapal segments light yellow, the flagellum darker. Head dark, 
any normal pruinosity destroyed. Thorax dark colored, un-
