The Crane-Flies of New York — Fart I 851 



The following additional notes on chiefly local species are presented: 



Tanyderidae: In Protoplasa fitchii, of the family Tanyderidae, the 

 antennae are 16-segmcnted; 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. 



Tipididae, Limnohiinae. — Limnobiini : 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 Elcphantomyia 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, d) 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,
