THe CRANE-FLIES OF New YorRK— Part I 897 
9. Wings with three small brown dots along the costal margin; head dark; antennae darkened 
toward the tips. [Proc. Acad. Nat. “Sei. Phila., p. 216. 1859.] (Plate XXXII, 35.) 
L. tristigma 0. S. 
Wings yellowish, unspotted; head yellow, excepting the front; antennae yellow. [Mon.

Limnobia cinctipes runs very close to L. immatura and apparently 
cannot always be distinguished from it; the character of an ocellate, 
yellow, brown-encircled mark at the stigma in L. cinctipes and a solid 
brown one in L. immatura does not hold in a series. L. hudsonica, L. 
solitaria, and L. fallax represent another group of closely related species. 
L. sociabilis is very rare and its exact status is still not well understood. 
Tribe Antochini 
The genera of the tribe Antochini may be classified in accordance

The author’s key to the Antochini given in Psyche (volume 20, pages 
40-41, 1913) is erroneous in the disposition of Dicranoptycha, which 
runs down into the couplet with Atarba as having the radial cross-vein 
lacking. The key was based on material that was not normal and 
should be emended as above. 
Genus Rhamphidia Meigen 
1830 Rhamphidia Meig. Syst. Beschr., vol. 6, p. 281. 
About eighteen species of the genus Rhamphidia are known, and they 
are distributed thruout all the major regions of the world. The larva 
of Rhamphidia longirostris (Palaearctic) has been found in the stems of
