THE CRANE-FLIES oF NEw YorK— Part I. 851 
The following additional notes on chiefly local species are presented: 
Tanyderidae: In Protoplasa fitchti, of the family Tanyderidae, the 
antennae are 16-segmented; the scape is enlarged, and the flagellar seg- 
ments are elongate-oval with a dense pubescence and verticillate bristles. 
In other Tanyderidae the number of segments ranges from 15 to 25. 
Ptychopteridae.— In the genus Bittacomorpha of the family Ptychop- 
teridae, the antennae are apparently 20-segmented. In the males they 
are elongated; the scape.segments are short, the second one being short- 
cyathiform; the flagellar segments are greatly elongated, with a long 
outstretched pubescence and no bristles. In Ptychoptera the antennae 
are 16-segmented, with distinct scattered bristles and a short, somewhat 
uncinate, pubescence. 
Rhyphidae.— In the genus Trichocera of the family Rhyphidae, the 
antennae are almost hairlike, tho finely pubescent. 
Tipulidae, Limnobiinae-— Limnobini: In the tribe Limnobiini the 
antennae are 14-segmented. In Limnobia (fig. 125, c) the segments 
have numerous bristles and a close, dense pubescence; the terminal seg- 
ment is usually much attenuated, about as long as the two preceding 
segments taken together, often presenting a biarticulate appearance. 
In Rhipidia a curious modification of the organ is found, the flagellar 
segments being bipectinate in the subgenus Rhipidia (fig. 125, a), unipecti- 
nate in the subgenus Monorhipidia (fig. 125, B), and from subpectinate 
to almost normal in the subgenus Arhipidia. 
Antochini: As a rule the antennae are 16-segmented in the tribe 
Antochini. The first scape segment is rather elongated, the second 
is oval, not markedly cyathiform. The flagellar segments are rounded- 
oval or elongate (in the males of most species of Atarba), with bristles 
and a short, dense pubescence. ‘The antennae are of this normal structure 
in the genera Rhamphidia, Antocha, Dicranoptycha, Atarba, and Teucho- 
labis. In Elephantomyia there are 15 segments; the first segment of 
the scape is only a little larger than the second; the first flagellar segment 
is apparently formed by the fusion of two segments, and bears three 
strong hairs on the lower face in a line; the remaining segments of the 
flagellum are elongate-cylindrical, with strong verticils. In the genera 
Toxorhina (fig. 125, p) and Ceratocheilus there are but 12 segments; the 
second scape segment is larger than the first; the first flagellar segment 
is obconical, and is apparently formed by the fusion of five segments,
