The Crane-Flies of New York — Part I 897 



9. Wings with three small brown dots along the costal margin; head dark; antennae darkened 

 toward the tips. [Proc. Acad. Nat. Sci. Phila., p. 216. 1859.] (Plate XXXII, 35.) 



L. trisiigma O. S. 



Wings yellowish, unspotted; head yellow, excepting the front; antemiae yellow. [Mon. 



Dipt. N. Amer., part 4, p. 95. 1869.] L. sociabilis O. S. 



Limnobia cindipes 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. cindipes 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 

 with the following key: 



1. Rostrum elongated, at least as long as the head 2 



Rostrum shorter than the head 4 



2. Rostrum about as long as the head or a very little longer Rhamphidia Meig. (p. 897) 



Rostrum about as long as the body 3 



3. Rs with two branches reaching the wing margin Elephantomyia O. S. (p. 898) 



Rs with a single branch reaching the wing margin Toxorhina Loew (p. 898) 



4. Gross-vein r lacking Atarba O. S. (p. 899) 



Cross- vein r present 5 



5. Anal angle of the wing prominent, almost square; Rs very elongate, straight; basal 



deflection of Cui before the fork of M Antocha O. S. (p. 899) 



Anal angle of the wing feeble; Rs shorter, more arcuated; basal deflection of Cui at or 

 beyond the fork of M 6 



6. Ri beyond the tip of Sc long, longer than the sector alone; veins issuing from cell 1st Mi 



very long Dicranoptycha O. S. (p. 900) 



^1 beyond the tip of Sc short, less than the length of the sector alone; veins issuing from 

 cell 1st Ml short Teucholabis O. S. (p. 901) 



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
